In this article, we will explore the technical aspects of audio bitrates. We will discuss what a bitrate is, how it affects audio quality, and how to choose the right bitrate for your needs.
What is a bitrate?
A bitrate is the number of bits per second that are used to encode an audio file. The higher the bitrate, the more data is used to encode the file, and the higher the quality of the audio will be. However, higher bitrates also result in larger file sizes.
How does bitrate affect audio quality?
Bitrate affects audio quality by determining how much data is used to represent the original sound waves. Higher bitrates allow for more data to be used, which results in more accurate representations of the original sound waves. This results in better audio quality, such as increased clarity and reduced noise.
How to choose the right bitrate
The right bitrate for you will depend on a number of factors, including:
The type of audio you are listening to. For example, music and speech have different requirements.
The quality of your audio equipment. Higher-quality equipment can reproduce higher bitrates without introducing any noticeable distortion.
Your personal preferences. Some people may prefer the sound of higher bitrates, while others may not notice a difference.
General bitrate recommendations
Here are some general bitrate recommendations for different types of audio:
Speech: 32 kbps to 96 kbps
Music: 128 kbps to 320 kbps
High-quality audio: 256 kbps to 512 kbps or higher
It is important to note that these are just general recommendations. The best way to determine the right bitrate for you is to experiment and see what sounds best to your ears.
Final words about audio bitrates
Audio bitrate is an important factor to consider when choosing an audio file format or when setting up an audio streaming service. By understanding how bitrate affects audio quality, you can choose the right bitrate for your needs and get the best possible listening experience.
As an audio enthusiast, I understand how crucial audio quality is for enjoying music or movies. In simple terms, audio quality refers to how good the sound is. But what makes a sound “good”? It’s a combination of factors like bit rate, sample rate, dynamic range, and compression.
In digital audio, bit rate refers to the number of bits of data that are processed per second. The higher the bit rate, the more information is transmitted, resulting in better sound quality. Sample rate, on the other hand, refers to the number of samples per second. A higher sample rate means more data is being captured, leading to a more accurate representation of sound.
When it comes to audio compression, there are two types: lossless and lossy. Lossless compression reduces file size without losing any audio quality, while lossy compression sacrifices some audio quality to achieve smaller file sizes.
“Audio quality is not just about the equipment you use, but also about how the audio is recorded and produced,” as Ken Pohlmann states in his book “Principles of Digital Audio”. It’s essential to consider the recording and mixing process to ensure high-quality audio output.
Analog vs Digital Audio
Analog audio refers to sound that is recorded and transmitted as an electrical signal. It’s been around for decades and is still used in some recording studios today. However, digital audio has taken over in recent years, as it’s more accurate and offers better sound quality.
Digital audio uses a binary code to represent sound, which is then converted back into an analog signal for playback. This process results in a more accurate representation of sound, and the digital format makes it easier to edit and manipulate audio.
As filmmaker George Lucas once said, “sound is 50% of the movie experience.” The switch from analog to digital audio has allowed for more immersive and realistic audio in movies and music.
Dynamic Range and Equalization
Dynamic range refers to the difference between the loudest and softest parts of an audio recording. It’s an essential aspect of audio quality, as a higher dynamic range means a more natural and realistic sound. However, too much dynamic range can cause distortion or clipping, so it’s crucial to find the right balance.
Equalization, or EQ, is the process of adjusting the balance between different frequencies in an audio recording. It’s used to enhance certain aspects of the sound, such as boosting the bass or adding clarity to the vocals. However, overuse of EQ can lead to unnatural or distorted audio.
As composer Hans Zimmer once said, “the music is never the problem, the music is the solution.” By understanding dynamic range and equalization, you can achieve the perfect sound for your music or movie.
Lossless vs Lossy Audio Compression
As mentioned earlier, lossless compression retains all the original audio quality while reducing file size. Lossy compression, on the other hand, sacrifices some audio quality to achieve smaller file sizes.
When it comes to music, many audiophiles prefer lossless formats like FLAC or ALAC, as they offer the best possible sound quality. However, these formats result in larger file sizes, which can be inconvenient for some users. Lossy formats like MP3 and AAC are more widely used, as they provide good sound quality while keeping file sizes small.
As filmmaker Quentin Tarantino once said, “When you’re watching a movie, you’re watching over the filmmaker’s shoulder.” The quality of the audio and video can greatly affect the overall viewing experience of a film. In this article, we’ll explore everything you need to know about audio quality, including bit rate, sample rate, and other related topics.
What is Audio Quality?
Audio quality refers to the overall fidelity, clarity, and richness of the sound in a recording. In other words, it’s how well the sound reproduces the original performance or source material. A high-quality audio recording will accurately capture the nuances of the original performance, while a low-quality recording will distort or lose some of these details.
Why is Audio Quality Important?
Audio quality is important because it directly affects the overall experience of listening to music or watching a film. Poor audio quality can distract from the content of the recording and make it difficult to understand what’s being said or played. In contrast, high-quality audio can make the recording more engaging and enjoyable to listen to.
As musician Brian Eno once said, “The quality of the sound is essential to the success of the music.” The same can be said for any audio recording, whether it’s a song, a podcast, or a movie soundtrack.
Understanding Bit Rate and Sample Rate
Two key factors that determine the quality of digital audio recordings are bit rate and sample rate. Bit rate refers to the amount of data used to represent each second of audio, while sample rate refers to the number of times per second that the audio is measured and recorded.
In general, higher bit rates and sample rates result in higher-quality audio recordings. For example, a CD-quality audio recording has a bit rate of 1,411 kbps and a sample rate of 44.1 kHz, while an MP3 file typically has a bit rate of 128 kbps and a sample rate of 44.1 kHz or lower.
Other Factors Affecting Audio Quality
In addition to bit rate and sample rate, there are other factors that can affect the quality of digital audio recordings. For example, the type of compression used can have a significant impact on the overall sound quality. Lossless compression algorithms, which preserve all of the original audio data, generally result in higher-quality recordings than lossy compression algorithms, which discard some of the original data to achieve higher levels of compression.
Other factors that can affect audio quality include the type of microphone or recording equipment used, the acoustics of the recording space, and the mixing and mastering process.
Conclusion: Why Audio Quality Matters
In conclusion, audio quality is a critical factor in any recording, whether it’s a song, a podcast, or a movie soundtrack. Understanding bit rate, sample rate, and other related topics can help you make informed decisions about how to record, edit, and distribute your audio content. By paying attention to audio quality, you can ensure that your recordings are engaging, enjoyable, and of the highest possible quality.
When it comes to creating video content, audio quality is often overlooked. Many content creators focus solely on the visuals and neglect the importance of high-quality audio. However, audio quality is just as important as video quality when it comes to creating engaging content. In this comprehensive guide, we’ll explore the importance of audio quality, the factors that affect it, and how to improve it to keep your viewers engaged and satisfied.
1. Defining Audio Quality
Before we dive into the specifics of audio quality, it’s important to define what we mean by “audio quality.” Audio quality refers to the clarity, richness, and overall sound of the audio content. This includes factors such as volume, tone, and background noise. The higher the quality of the audio, the more enjoyable the listening experience for the audience.
2. The Importance of Audio Quality
2.1 Improving User Experience
High-quality audio is crucial for a good user experience. Viewers are more likely to engage with video content that has clear and crisp audio. Poor audio quality can lead to frustration and disappointment, causing viewers to lose interest in the content.
For example, imagine watching a video with muffled or low-quality audio. You may struggle to understand what is being said, or you may become distracted by background noise. This can take away from the overall viewing experience and make it difficult to stay engaged with the content.
On the other hand, high-quality audio can enhance the viewing experience, making it more enjoyable and engaging. Clear and crisp audio can help to create a more immersive experience, drawing viewers into the content and keeping them engaged from beginning to end.

2.2 Impact on Perceived Video Quality
Audio quality also affects the perceived quality of the video content. If the audio quality is poor, viewers may assume that the overall video quality is also low. This can lead to negative perceptions of the content and discourage viewers from watching more videos from the same creator.
For example, imagine watching a high-quality video with poor audio. Even though the video quality may be excellent, the poor audio quality can make the content seem amateurish or low-budget. This can negatively impact the viewer’s perception of the content and the creator.
On the other hand, high-quality audio can enhance the perceived quality of the video content, making it seem more professional and engaging. When the audio quality matches the video quality, viewers are more likely to perceive the content as high-quality and engaging.
Long-tail keyword: “The effects of poor audio quality on viewer engagement”
2.3 Impact on Viewer Engagement
In addition to affecting the perceived quality of video content, audio quality can also have a significant impact on viewer engagement. When audio quality is poor, viewers may quickly lose interest and stop watching. This can result in lower audience retention, decreased watch time, and lower engagement rates.
Conversely, high-quality audio can help to keep viewers engaged and enhance the emotional impact of video content. Clear dialogue, well-balanced music and sound effects, and a lack of distracting background noise can all contribute to a more engaging and immersive experience for the viewer.
Studies have shown that high-quality audio can have a direct impact on viewer engagement and audience retention. For example, a study conducted by Dolby Laboratories found that viewers were more likely to remember and engage with content that featured high-quality audio. The study also found that viewers were more likely to share content that had good audio quality, indicating that high-quality audio can also have a positive impact on social sharing and virality.
2.4 Sound Design and Audio Quality
Sound design is an important aspect of audio quality in video content. It involves the use of music, sound effects, and other audio elements to enhance the emotional impact of video content and create a more immersive viewing experience. Effective sound design can help to establish the mood and tone of a video, convey important information, and create a sense of continuity between different scenes.
Music is a particularly important element of sound design, as it can evoke specific emotions and create a memorable experience for the viewer. For example, a fast-paced, upbeat soundtrack can create a sense of excitement and energy, while a slow, melancholy melody can convey a sense of sadness or reflection.
Sound effects are another important aspect of sound design, as they can help to create a more immersive and realistic viewing experience. For example, the sound of footsteps, doors opening and closing, and other ambient noises can help to create a sense of presence and realism in a video.
2.4.1 Music and Audio Quality
When it comes to music in video content, it’s important to use high-quality recordings that are well-mixed and balanced. Poorly-mixed music can be distracting and detract from the overall quality of the video, while well-mixed music can create a more immersive and engaging experience.
In addition to the quality of the recording, it’s also important to consider the musical style and genre. The music should complement the tone and mood of the video, and should be appropriate for the target audience. For example, a video aimed at children might feature bright, cheerful music, while a video aimed at adults might feature more mature or sophisticated music.
2.4.2 Sound Effects and Audio Quality
Like music, sound effects should be of high quality and well-mixed to ensure that they don’t detract from the overall quality of the video. When choosing sound effects, it’s important to consider their appropriateness for the scene and the emotional impact that they will have on the viewer.
For example, a video that features a dramatic car chase scene might use sound effects such as screeching tires, engine revving, and crashes to create a sense of excitement and danger. In contrast, a video that features a quiet, introspective moment might use sound effects such as birds chirping, leaves rustling, or a soft breeze to create a more peaceful and reflective atmosphere.
3. Conclusion
In conclusion, high-quality audio is a crucial element in producing engaging and impactful video content. Investing in the right equipment, such as a high-quality microphone, and optimizing the recording environment can greatly improve the overall audio quality.
Not only does good audio quality impact the perceived quality of the video, but it also plays a significant role in audience engagement and retention. Poor audio quality can result in viewer frustration and disinterest, ultimately impacting the success of the content.
By understanding the importance of audio quality and taking steps to optimize it, content creators can create a better experience for their viewers and increase the overall impact of their content. Additionally, sound design and music can further enhance the quality of the audio and create a more immersive and emotional experience for the audience.
It’s important to remember that good audio quality is not just important for video content, but it also plays a crucial role in other contexts such as in education, entertainment, and advertising. The use of audio has evolved over time, and platforms have adapted to the preferences of users.
Overall, by recognizing the impact of high-quality audio and taking steps to improve it, content creators can enhance the experience of their audience and increase the success of their content.
Note 1: Types of Microphones
There are several types of microphones that content creators can choose from to achieve high-quality audio. Understanding the differences between each type can help creators make an informed decision about which microphone is best for their needs:
1. Dynamic Microphones
Dynamic microphones are the most durable and versatile type of microphone. They are ideal for recording vocals and instruments with a high sound pressure level, such as drums and electric guitars. They are also less sensitive to background noise, making them a good choice for recording in noisy environments.
2. Condenser Microphones
Condenser microphones are known for their high sensitivity and clear sound quality. They are ideal for capturing the nuances of acoustic instruments and vocals, making them a popular choice for recording studios and podcasting. However, they are more delicate than dynamic microphones and require phantom power to operate, which may not be available on all recording devices.
3. Ribbon Microphones
Ribbon microphones are a specialized type of dynamic microphone that use a thin strip Hf metal suspended in a magnetic field to capture sound. They are known for their warm and natural sound quality, making them a popular choice for recording vocals and acoustic instruments, such as guitars and strings.
When choosing a microphone, it’s important to consider the specific needs of the recording environment and the type of content being produced. With the right microphone and proper techniques, creators can achieve high-quality audio that enhances the overall user experience.
How Noise Reduction Software Works
How Noise Reduction Software Works: Noise reduction software is a type of audio processing tool that analyzes an audio signal and removes unwanted noise or interference. It works by detecting patterns in the noise that are different from the patterns in the desired audio signal, and then subtracting those patterns from the overall signal.
One common approach is to use a technique called spectral subtraction, which works by taking a short-term Fourier transform of the audio signal to identify the frequency spectrum of the noise. The software can then create a filter that selectively removes those frequencies from the signal, leaving the desired audio intact.
Another approach is to use machine learning algorithms to train the software to recognize different types of noise and automatically remove them. This can be particularly effective for complex or variable noise sources, such as the sound of traffic or wind.
While noise reduction software can be effective, it’s important to note that it’s not a silver bullet. Some types of noise may be difficult or impossible to remove without degrading the quality of the desired audio signal.
Nota 3: Understanding Decibels
Understanding Decibels: Decibels are a unit of measurement that is used to express the intensity of a sound. The decibel scale is logarithmic, which means that a small change in decibel level represents a large change in actual sound intensity.
The threshold of human hearing is generally considered to be around 0 decibels, while the threshold of pain is around 120 decibels. Common sounds like conversation or music may be around 60-70 decibels, while a rock concert or chainsaw can easily exceed 100 decibels.
The reason for the logarithmic scale is that the human ear is not equally sensitive to all frequencies of sound. By using a logarithmic scale, we can better represent the way that the human ear perceives changes in sound intensity across different frequency ranges.
It’s important to be aware of the decibel levels in your environment, as exposure to loud sounds over time can cause permanent hearing damage. This is particularly important for people who work in loud environments, such as construction or music production.
The higher the kbps value of the mp3 file, the better the sound quality? Part 2
MPEG audio encoding has a high compression ratio, MP1 and MP2 have a compression ratio of 4:1 and 6:1-8:1 respectively, while MP3 has a compression ratio of up to 10:1-12: 1, which means that one minute Uncompressed CD-quality music requires 10 MB of storage space, but only about 1 MB after MP3 compression encoding, and its sound quality is basically distortion-free.
Although it is a distorted compression, its biggest advantage is a higher compression ratio in exchange for very little sound distortion. Usually a CD can only store a dozen CDs, but it can store hundreds of MP3 songs, which is why MP3 is popular all over the world. Currently, MP3 is the most common music format on the Internet. Music files of the same length are stored in the MP3 format, usually only 1/10 of the WAV format. Due to their small file size and good sound quality, they can achieve a sound effect that is closer to the original sound source. Therefore, until now, the status of MP3 format as the mainstream audio format is still hard to shake. Simply put, WMA is smaller than MP3 and MP3 has better sound quality than WMA. Currently, the music format with the best sound quality is APE, which is equivalent to the sound quality of a CD, but relatively large. A song weighs about 20 MB! 1 or so, another advantage of WMA is that content providers can add copy protection through DRM (Digital Rights Management) solutions, such as Windows Media Rights Manager 7. This copyright protection technology built-in author can limit the playback time and number of playback, and even the playback machine, etc., which is a boon for music companies that have been defeated by piracy. MP3 format: MP3 technology originated From MPEG technology, MPEG is short for Moving Picture Experts Group. MPEG audio encoding has a high compression ratio, MP1 and MP2 have a compression ratio of 4:1 and 6:1-8:1 respectively, while MP3 has a compression ratio of up to 10:1-12: 1, which means that one minute Uncompressed CD-quality music requires 10 MB of storage space, but only about 1 MB after MP3 compression encoding, and its sound quality is basically distortion-free.
The higher the kbps value of the mp3 file, the better the sound quality?
Kbps refers to the number of bits (bit rate) of mp3, and bit rate refers to the amount of information that can be transmitted per second in a data stream.
Kbps means “kilobytes per second,” so a higher value means more data, a higher bit rate, more information, and better sound quality, but it also means more processing to decode the information. the more space the file should take up. (But this is nothing compared to today’s hardware, and many people put ape directly on the hard drive!) For mp3, 128kbps is a qualified quality! As for the bit rate you use, it depends on your own needs. If the requirements are high, use CBR320kbps, CBR192kbps or VBR variable bit rate. If the file size is required to be small for network streaming or online playback, please use CBR128kbps or lower bit rate can be. Sound quality is closely tied to its compression ratio. In fact, WMA is slightly worse than MP3 at a rate of 192 kb/s or higher, but it is quite close to the effect of the original WAVE file. The difference is that the treble component of WMA in the same ratio is greater than that. of MP3 in the ratio of 96K and 64K. Simply saying that WMA is more advanced than MP3 is untenable. In fact, their principles are the same, and they are similar in the case of high ratios. Also, there is a problem with the compression software: if you use Hero Jieba to compress high-quality MP3, it will definitely be worse than WMA. Now LAME has grown considerably and is stronger than WMA at ratios above 128K. Comparing 96K WMA with 128K MP3, MP3 is definitely better. So it depends on your needs, if you need low baud, MP3 PRO or WMA is recommended (MP3 PRO is much better than WMA at 64K ratio), and if it’s high quality MP3, it doesn’t matter, but it’s still recommended. MP3, because after all it is a fairly open format, unlike WMA, which is monopolized by the Microsoft family, and can only be played with WMP. For that, I only use MP3. WMA format: WMA sound quality is stronger than MP3 format, its “body” is thinner than MP3, and it supports data transmission technology (Stream), which can be downloaded and listened to on the Internet. The characteristic of WMA is that when a song is compressed to a very small size, it can still maintain good sound quality, which is much better than RA format. It is the same as the VQF format developed by YAMAHA in Japan. Reduces data stream but maintains sound quality method to achieve higher compression ratio than MP3. The compression ratio of WMA can generally reach around 18:1. Another advantage of WMA is that content providers can add copy protection through DRM (Digital Rights Management) solutions, such as Windows Media Rights Manager 7. This built-in copyright protection technology can limit the playing time and the number of plays, and even the playing machine, etc., which is a blessing for music companies that have been defeated by piracy .MP3 Format: MP3 technology originated from MPEG technology, MPEG is short for Moving Picture Experts Group. MPEG audio encoding has a high compression ratio, MP1 and MP2 have a compression ratio of 4:1 and 6:1-8:1 respectively, while MP3 has a compression ratio of up to 10:1-12: 1, which means that one minute Uncompressed CD-quality music requires 10 MB of storage space, but only about 1 MB after MP3 compression encoding, and its sound quality is basically distortion-free. Although it is a distorted compression, its biggest advantage is a higher compression ratio in exchange for very little sound distortion. Usually a CD can only store a dozen CDs, but it can store hundreds of MP3 songs, which is why MP3 is popular all over the world. Currently, MP3 is the most common music format on the Internet. Music files of the same length are stored in the MP3 format, usually only 1/10 of the WAV format. Due to their small file size and good sound quality, they can achieve a sound effect that is closer to the original sound source. Therefore, until now, the status of MP3 format as the mainstream audio format is still hard to shake. Simply put, WMA is smaller than MP3 and MP3 has better sound quality than WMA. Currently, the music format with the best
People often use Kbps to describe the hearing effect and audio quality.
On Windows systems and some players, kbps is called “bit rate” and “bit rate”.
16Kbps=phone sound quality
24Kbps=Increased telephone sound quality, short wave transmission, long wave transmission, European standard medium wave transmission
40Kbps=US standard medium wave transmission
56Kbps=Voice
64Kbps=Voice boost, mobile phone ringtones the best bit rate (Kbps) setting value, mobile phone The best setting for mono MP3 players is
112 Kbps = FM FM stereo transmission 128 Kbps =
best setup for cassettes, mobile phone stereo MP3 players, best setup for low-end MP3 players
192 Kbps = the best setting for mid-range MP3 players The fixed value of
320 Kbps = the best setting for high-end MP3 players (the highest bit rate on the
MP3 format) The highest quality of the MP3 format is 320 Kbps
2. How to distinguish true and false KBPS
The maximum quality in MP3 format, the bitrate is 320Kbps, but it is not ruled out that some unscrupulous merchants convert low quality audio (such as: 40, 64, 128 kbps) to the maximum quality (320kbps);
for a long time, many people Judgment on sound quality depends entirely on the bitrate of the dance music, i.e. whether the audio file is 192k, 256k or 320k (the bitrate in the file mp3-properties-detailed information), but in fact, this parameter does not really reflect a song. The sound quality of music is data that can be falsified and cannot fully represent the actual sound quality of a song. For example, using software such as QianqianjingTing, you can convert a 64Kbps music to 320Kbps, but before conversion and conversion After the sound quality is the same, the sound quality has not really improved.
With the proliferation of digital storage and streaming, few people listen to music with physical objects.
Earlier I asked a high school student that he didn’t use the tape and that he didn’t know what it was. It was really shocking!
That’s the tape thank you!
Now almost all the music we listen to comes from the internet, be it Youtube or Soundcloud, Spotify or songs downloaded from iTunes or Beatport. Most of the time we don’t think that the sound transmitted by these different platforms is different, but there are times when we suddenly feel that the “sound quality” is not very good, but often we don’t know what the sound is. quality is What is the meaning?
Today we will introduce you to what this “sound quality” really means and the principle behind it.
First of all, everything we hear from the Internet are digital files, that is, the real (continuous) sound is saved by sampling (slicing) and then restored by decoding. So generally the quality of the sound we hear has two levels: one is how finely the song itself is sampled, and the other is how realistic our playback system is when playing it.
If you take a video as an example, you can see the fineness of 480p, 1080p, 4K video in the image below.
And this is similar to the finesse of the song itself: the finer the sample, the better the sound quality. But we actually see the image through the screen, so even though I have 4K HD video, I still see it on a traditional VCR. It may be the same as 480p, because your player can’t play it. Good quality. It’s like buying a CD and listening to it with the 39 yuan headphones Daiso bought.
But today we are more focused on the level of sophistication of the original song. The two most important elements that affect the sound quality of digital music are the sample rate (Hz) and the bit depth (bits), which are the horizontal and vertical axes in the figure below.
The so-called sample rate is the number of points we want to take in 1 second to sample (horizontal axis), and the bit depth is the density of the scale we want to set on the vertical axis.
The following image shows the difference between the sample rate of 100 Hz and 33 Hz, respectively. The black line is the original waveform.
Connect the sampled lines and compare them to the original waveform to learn the effect of the sample rate on the sound. 100 Hz is significantly closer to reality than 33 Hz.
At this time, someone will ask, so you can get 100 million Hz, and it is guaranteed to be the same as the real thing. Basically yes, but there will be a big problem with this, the file will be very big and it can take a year to upload a song. And the numbers are generated to speed up the transmission speed, so this is not acceptable!
To achieve a perfect balance, you need to set a suitable sample rate, which makes people sound good, but the file is not too big, and the bottom line is that it should be at least 44.1kHz. Because according to the sampling theory, the sampling frequency should be greater than twice the bandwidth of the sampled signal, and people can hear the sound up to 20,000 Hz, so we take a little more than 2 times as the standard minimum.
The object of comparison is that the general local dialect is 8000Hz. You can listen to the CD and compare the microphones.
Of course, there are 48,000 Hz and 96,000 Hz or even more, but 96,000 Hz is enough by industry standards.
The following is the common bit depth of 16 bits, 24 bits, which is the 16th power of 2 and the 24th power. What it affects is the part of the vertical axis that we just mentioned, as shown in the figure.
It can be seen that the dynamic range that 24-bit can record is larger than that of 16-bit, in other words, the sound you hear can be more vivid, in other words, it can accommodate a larger dynamic range.
When downloading music, we often see these options: lossless sound quality and normal sound quality, lossless sound quality requires members to download, otherwise only normal sound quality can be downloaded. Since it is a fee, the lossless sound quality must be higher than the normal sound quality, so what are the differences between them?
What does kbps mean?
Different compression encoding methods
Commonly seen MP3, WMA, OGG are called lossy compression. As the name suggests, lossy compression is to reduce the audio sample rate and bit rate, and the output audio file will be smaller than the original file, which is normal sound quality. we often see.
Another audio compression is called lossless compression, which can compress the volume of the audio file to a smaller size on the premise of saving 100% of all the data in the original file. Same size, same bitrate. Lossless compression formats include APE, FLAC, WAV, WavPack, LPAC, WMALossless, AppleLossless, TTA, Tak, TAC, La, OptimFROG, Shorten, while common and conventional lossless compression formats today include APE, FLAC, TTA, TAK, WAV, Generally CDs are lossless music.
What does kbps mean?
different file sizes
Common MP3, WMA and other formats occupy about 1M-5M space for single-handed songs, while for music in lossless formats such as ape and flac, the space occupied by a single song can generally reach tens of megabytes, or even more than 100M.
different bit rates
Bit rate (Kbps) refers to the transmission rate of digital signals, that is, how many thousands of bits of information are transmitted per second (K means thousands of bits, Kb means how many thousands of bits). For music, theoretically this The higher the value, the better the sound quality. Ordinary music, such as WMA, is generally 128kbps music, MP3 is mostly 128 or 192 or 320kbps/, while the bit rate of lossless music generally reaches 800-900kbps, and traditional CD even reaches 1411 Kbps. Using lossless compression, the sound quality is the most perfect.
What does kbps mean?
different sound
The feature of lossless music is that regardless of whether there is sound between the beats, its data always flows smoothly, so the fast magnetic vibration in your headphones is stable, and the sound is natural and real; while lossy formats such as MP3 are due to the loss of people The ear can not hear part of the data, so the magnetic block in the earphone vibrates unnaturally, causing it to vibrate when there is sound, and do not vibrate when there is no sound, so the magnet block vibrates excessively and unstable, which will produce burr noise. If professional equipment is used, it is easy to hear right and wrong.
