Are your ears worthy of your headphones?…

The process of human hearing sound is very complicated.

But compared to the metaphysics of headphones and audio, the complexity of the human ear is basically not worth mentioning. But before we get into whether Beats is shallow, whether Sony is good, and whether headphone noise reduction is good for your ears, let’s take a look at what we’re talking about when it comes to sound quality. It may be that when you feel that the sound quality of a certain headset is not good, the problem is in your ears or in the sound file itself.

01 What is sound quality?

The essence of music and sound is the vibration of air, and sound quality is generally attributed to three aspects: volume, pitch, and timbre.

Everyone knows the volume and the tone is Do Re Mi Fa Sol La Ti. And what is the tone?

The American National Standards Institute defines timbre as “…a sensory attribute by which a listener can judge that two tones of the same volume and pitch are not the same.” We can tell the difference between a guitar playing a 440Hz tone and a piano playing a 440Hz tone.

The sound reproduced by different headphones is different, and the timbre is also different. However, in terms of volume, different headphones will also have a certain volume difference due to different internal circuitry; as for the tone, there is no obvious change without accident.

02Digital recording and analog recording

There is no doubt that pre-CD audio carriers: magnetic tapes, vinyl records, etc., are all analog recording products. The word “analog” is also translated as “analog”, in short, it restores and reproduces the vibration in the air at that moment in a physical way. Whether it’s vinyl or tape, physical features such as bumps, depressions, or magnetic dust splits on tape or disc are used to restore the vibrance detail of the audio.

But in the age of CDs and computers, all audio vibrations are converted to 0 or 1 on the surface of the disc and go into the so-called binary algorithm. After decoding, it is restored to physical vibration.

In popular music recordings, there are probably three most common formats:

44.1 kHz, 16-bit waveform

320kb mp3

128kb mp3

Mp3, is it the best format for music and sound?

People are looking for the best audio and video quality in 2022, what is it?

If you are seriously looking for high-quality audio and video, we advise you to stay away from the data-throwing fundamentalists and adopt a more practical attitude.

First of all you must ask yourself, on which devices will you listen to the audio or see the videos.

We have listened to dozens of fundamentalists who use numbers and certain statements as dogmas and have turned even this discussion of quality into a dogma.

And that is diametrically different from the simple my real aspiration to really enjoy the best audio and video quality that your equipment can deliver and that your eyes and ears are capable of detecting.

Mathematical statements are useless if you do not have an HD computer to listen to your audios and watch your videos.

Nor if the extreme is reached where the difference is already indistinguishable for 99.99% of the population.

It is fully demonstrated that for 99.99% of the population, even for those who have auditory training, an mp3 with 320 kbps and 48000 as sample rate is indistinguishable from a WAV or FLAC.

You can improve your audio with Mp4Gain regardless if you decide to continue using mp3s or prefer to switch to FLAC (Mp4Gain can convert and use these and other formats like ogg, m4a, etc)

In short, the discussion of sound quality should be based more on actually hearing the best possible audio and not a fundamentalist discussion about numbers.

The audio formats with the best sound quality

audio formats

In addition, when editing, because some details have been compressed and sacrificed, the editing space is relatively small.

audio formats

It should be noted that the sound quality will be compromised every time these formats are output. After too many output programs, the quality can be terrible, so the number of times of recompression and conversion should be reduced.

Pros: small file size, maximum device compatibility

Disadvantages: destructive compression leads to loss of sound quality, less spatial flexibility for reissue

Resume
When it comes to sound files for editing, it’s ideal to work with uncompressed formats like .WAV or .AIFF. Such a format allows users to get the greatest degree of tolerance and freedom when editing, and most of these file formats are still supported, regardless of software or equipment. Also, when the video is output at the end of the project, the music file will still be compressed, so it’s ideal to use a file format with higher sound quality from the start, which is ideal for a project that needs to go through post-edit layers. But if it is based on the premise of convenient, fast and easy-to-use transmission, .MP3 can still meet your needs without sacrificing sound quality.

Mp4Gain is a program that allows you not only to normalize the audio of your sound or cvideo files, but also to improve the quality and offers you to perform a whole series of modifications so that you have better audio quality used.

The audio formats with the best sound quality

First of all, divide all types of music files into three parts as follows:

Uncompressed file formats: .WAV, .AIFF

Lossless compression formats: .FLAC, .ALAC (Apple Lossless)

Destructive compression formats: .MP3, .AAC, .WMA, .OGG

Below are their respective advantages and disadvantages.

1. Uncompressed file format
Uncompressed music files are just like the concept of Raw files. Essentially no compression will of course have the best sound quality. (The sample rate and bit rate of the original recording are also very important. If the compressed music file is converted to an uncompressed file, the music won’t magically improve the sound quality.)

The most common disadvantage of uncompressed files is the file size. Generally, the file size of a song is around 25 ~ 40 MB. While that capacity is no longer an issue for cloud hard drives, it is still an issue for email. Also big (25MB max for Gmail attachments). Also, some portable music players or devices may not be able to play such music files.

Advantages: original sound reproduction, no compression, lossless, easier to use in post production

Disadvantages: large file format, fewer supported devices

2. Lossless compression format
The term “compressed and lossless” seems contradictory, but compression does not necessarily affect sound quality. More precisely, it’s more like “compressed to save space”. It’s like compressing a high quality file into a .ZIP and decompressing it when you want to use it, the quality of the file will not be affected.

Therefore, this type of file has a compressed capacity, but the file will be decompressed during playback to restore sound quality. Although the concept of reducing capacity without affecting sound quality is great, the downside is that support for this format is extremely low and in order to decompress the file during playback, an additional codec is required to use it, and it will. also take some performance.

Advantages: small file capacity (about 1/2 ~ 1/3 lossless files), good sound quality

Disadvantages: Decompression can eat performance when used, and support from hardware or software is extremely low

3. Destructive compression format
The destructive compression format is currently the most common music file format, the main reason is that it has the greatest compatibility with portable devices (mobile phones, MP3 players, etc.), and the files are small and have a space of limited storage. , users can store more music (compressed capacity is about one-tenth of lossless sound quality), and most of the music provided by today’s streaming media is files in this format. There is always a price to pay for smaller files. Compared to lossless formats, this destructive compression will affect the audio range that the original sound can present and will cause some distortion. So, to be safe, keep the compression rate above 320 kbps as much as possible.

What sound quality is best for the music we listen to in the car?

Listen music in the car

There are two suggestions for car music sound quality:

1. Many music lovers, who are looking for extremely high music quality, will be interested in high quality and lossless formats like OGG, FLAC or AAC.

However, due to the limited music formats that the car can recognize, music files of the above formats may not be recognized by the car.

Let alone play it.

2. In general, in the field of car music, the most commonly used formats are MP3 and WMA.

Although these formats are not as good as the ones mentioned above in terms of sound quality, they are expensive because almost all car systems can recognize them.

So, if you want to say which music file format is the best in car music, it has to be MP3 and WMA.

What sound quality is best for the music we listen to in the car?

The best audio hardware equipment is one of the most important factors that determine sound quality.

This is also related to the degree of distortion of the music being played, that is, how well the sound reproduction is restored.

This directly affects the mood of the listener. Because if the sound is loud and has no sense of hierarchy,

If you listen to it for a longer time, it will irritate you or make you feel dizzy when driving.

The other is to adjust the sound effect by yourself. After all, everyone’s sense of hearing is different.

It depends on what you adjust to make it comfortable to listen to. Adjust different parameters according to different types of music.

There will be unexpected effects.

I myself belong to the latter, although I am not a professional,

But with lossless sound quality (my car supports it, but it’s not a luxury car)

It can also bring out the feeling of fat low-frequency, clear mid-range, and bright highs (this takes some skill to distinguish),

But not all cars have sound quality adjustment.

As for the best car music sound quality, as mentioned in the article above, car music can download music with sound quality wav, ape, flac,

This is lossless sound quality, better than MP3 (as long as the device supports it).

Although now it connects via Bluetooth mobile phone or Baidu Carlife

Playing music online on mobile phones has become mainstream, but there are still a small number of people,

Insist on downloading via U disk, and use the car USB interface to play music.

What is the best audio format to get the best sound quality?

Best Audio Format

Mp3, Wav, Flac… Which one is better?

Best Audio Format

We’ve heard so many discussions about whether mp3 can sound the same as wav or flac and there are advocates for both.

There are people who staunchly defend mp3 and show and prove that an mp3 generated with certain settings can sound so similar to a WAV that not even 1% of people with ear training can distinguish it.

Others, on the contrary, argue that the method used by the mp3, causes a lot of information to be discarded in order to make the file smaller and this necessarily causes the quality to be diminished.

But everyone forgets that the number one point is to think about what kind of device or audio player we will listen to the music. Because for all these niceties mentioned above to make sense, we’ll have to have equipment that can play HD audio, otherwise we won’t easily tell one from the other.

And the truth is that most people play music on a medium quality equipment in a car on a phone or on a laptop, which makes the question of whether an mp3 sounds very different from a wav is unnecessary.

Mp4Gain is a program that manages to make audio, whatever the format, sound the best it can be.

What is the best sounding audio format? Is it MP3?

The audio formats with the best sound quality are

mp3
b, wav
c, wma
d.rm

Answer: The

B wav format files are usually stored on the computer The most widely used file format is an uncompressed format, which stores the most authentic and original sampled data, that is, the sampled data of the set frequency and bit depth they are true and lossless, like 44.1 kh/16-bit audio CD quality, other frequencies and bit depths can of course be stored.

Below are other audio file formats:

1. Format

MP3 MP3 is an audio compression technology that compresses files to a small volume on the premise of losing a certain amount of high-frequency timbre data. The highest bitrate can only reach 320K. The frequency part is basically lost.

2. Format

WMA WMA is Windows Media Audio from Microsoft. The WMA format has a higher compression rate than MP3 and the generated files are smaller. It is suitable for transmission in low-speed networks many years ago.

3. Format

FLAC FLAC is lossless audio compression. Since it is lossless compression, it will not destroy any original audio data information and can restore the sound quality of the music on the CD. FLAC is very similar to MP3, but it is lossless compression.

4. The format

APE APE is similar to FLAC and is also a lossless audio compression technology.

Something very important, that we will develop in another article and that is almost always ignored when it comes to comparing audio formats, is the equipment or device that we use to play music.

That is the point from which we should start.

What audio format should I choose?

What audio format should I choose?

Best Audio Format
Everybody loves music. Some listen to it on the way to work, and others can’t go a minute without their favorite songs. Listening to music comfortably depends not only on the mood, the time, the moon phase and good headphones, but also on the audio format in which it is stored on our devices.

In the 21st century, streaming services are becoming popular, but most people still store music offline and listen to it from their phones, players, audio systems, etc. But this post is not a discussion “Which headphones are better?”, “Why listen to music?” or “Why vinyl, not CD?”, but a brief summary of today’s most popular digital audio formats, their pros and cons. I will not analyze them all, and I will not compare different encodings, the differences “this AAC from this AAC”, but I will try to count in an accessible way the differences of some popular audio formats from each other.

So what is the best way to store your music collection? Today, there are many digital audio formats, and if you want, you can see a list of them on Wikipedia. But we will focus only on MP3, AAC, WMA and FLAC.

MP3

The most popular audio format and nobody can argue with that. Why is it so popular? It’s simple, because Mp3 was the first audio format with the best ratio (at the time) of file size and quality when compressed. Therefore, most of the songs were translated into MP3, which served as the undisputed primacy of the audio format on the market.

The advantages are clear from the previous paragraph: small size, tolerable compression loss, ubiquity, compatibility with all devices, and also, due to the small size, you can store a large collection of songs on a medium with little memory capacity, which it is also an advantage for some.

But Mp3 also has some disadvantages. Even though compression losses are not visible to ordinary people, knowledgeable people will notice them immediately. This is a low sound quality compared to other audio formats, as well as a “cut” of frequencies above 17 kHz, which is felt by ear with good headphones.

AAC

The young audio format AAC, mainly promoted by Apple, can be considered the successor to Mp3. AAC seems much more advantageous because Compared to MP3, AAC file compression is more efficient. At a bit rate of 128 kbps, an AAC composition is comparable in sound quality to the same MP3 composition at a 192 kbps bit rate.

Better compression quality is a major advantage of AAC. The disadvantage is not the same prevalence as in the same mp3. Some devices do not yet support this format. And also the compositions in AAC take up more space than in MP3. Not as much as FLAC, but still, for some it is a critical factor.

WMA

The WMA format was created by Microsoft as an alternative to Mp3 for Windows users. It was believed that with half the bit rate of MP3, WMA produces similar quality. But, in fact, the composition in WMA at 128 kbps is noticeably lower than that of Mp3. The advantages include full Windows support, but the disadvantage is extremely low quality at a low bit rate. By personal observation, I will say that I have not seen people storing their music in this audio format for a long time.

FLAC

One of the most common audio formats for music lovers in good quality. FLAC compresses the data, leaving it in the output identical to the original, without losing any data, which is the main lossless compression algorithm. Furthermore, decoding the FLAC format does not require as much processor resources, allowing you to listen to music on portable devices.

The advantages of music in FLAC are excellent quality and fast decoding, but a disadvantage, as a result, is the large file size.

So in what audio format should you keep your music collection? If you are not so critical of losses after compression, if you want to make a mistake with the support, so that your collection does not become a bunch of useless files in 5 years, you have a limited amount of memory for your music, then choose Mp3. If free space allows you to store larger files, switch to AAC. I personally don’t recommend WMA. I think this audio format is dead, although most people will not agree with me. And if quality is important to you, you have a good audio system or headphones, and even minimal compression loss is inexcusable for you, then FLAC definitely is. But be prepared for the fact that you must have plenty of room for music.

The best popular audio formats

The best popular audio formats

I looked around the forest of audio formats for normal use and chose the 5 most important ones. It is true that, in part, a bit simplified, a bit rough in presentation. I refrain from differentiating the exact settings of the respective codecs, that would be too complex.

I also don’t want to get into the nasty topic of DRM. The most important one I dropped is probably Vorbis. . Of course, I assume that the correct settings are used when encoding and that a high quality level is selected.

1st place:
MP3 (MPEG-1 Audio Layer 3)

The most widespread digital format, with good encoding (for example, with LAME) in high bit rates, a format of the highest quality and transparency.

Quality (4.5 / 5 points)
Popularity (5/5 points)
Compression (4/5 points)
Total: 13.5

2nd place:
AAC (advanced audio coding)

It became famous especially for its use in the Apple iPod, a codec that has small advantages over MP3 at low bit rates due to technical developments.

Quality (4/5 points)
Popularity (4.5 / 5 points)
Compression (4.5 / 5 points)
Total: 13

3rd place:
WMA (Windows Media Audio)

Windows proprietary format. Of course, Microsoft has the reins here, so variable format doesn’t run on all playback devices. Otherwise, no major strengths and weaknesses and, for example, the standard format with Napster.

Quality (4/5 points)
Popularity (4/5 points)
Compression (4/5 points)

Total: 12

4th place:
FLAC (Free Lossless Audio Codec) !!

As the only lossless codec on this list. FLAC works in something like a ZIP program: the original can be restored from the compressed file by approximately 50% without restrictions. In times of low hard disk space, a real alternative, especially since many playback devices can play this format. My winner of hearts, the popularity will certainly increase in the future.

Quality (5/5 points)
Popularity (3.5 / 5 points)
Compression (3/5 points)

Total: 11.5

5th place:
Wav

The original format of the normal audio CD data. Impeccable quality and still widespread thanks to the well-known compact disc. It actually started out of the competition because it’s completely unzipped.

Quality (5/5 points)
Popularity (5/5 points)
Compression (0/5 points)
