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.

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)

All about all audio file formats

Dematerialized music has evolved considerably for almost 15 years and has played an important role in the daily life of every individual. We’ve all heard more or less about FLAC, MP3, WAV, etc.! Few people really know the difference between each size, its pros and cons …

This article is intended to enlighten you to make the best possible choice for extracting and compressing your audio files.

There are different types of layouts that can be grouped into several large families:

– uncompressed files

-lossless compressed files

– Lossy compressed files

audio formats

-Uncompressed files

WAV: WAV (Waveform Audio File Format) is an audio file format created by Microsoft for Windows. This format is usually an uncompressed container. Therefore, an audio CD with a duration of about 80 minutes in WAV weighs plus or minus 800 MB

Advantages: the file remains in its original form, no loss of information (no loss)

Disadvantages: The WAV file is an uncompressed format that gives it a large size and therefore takes up more space in the storage space.

AIFF – Audio Interchange File Format (AIFF) is the Mac OS equivalent of the WAV format. Therefore, it has the same characteristics as this. The pros and cons of this format are the same as for WAV.

– Lossless compressed files

FLAC: The FLAC (Free Lossless Audio Codec) format is without doubt the most beneficial file for the user. Firstly, in terms of WAV and AIFF, this format is a lossless format, ie the digitization of the file does not imply any loss of information from the audio spectrum. The file is scanned and returned as is. The second advantage of this format is the size it occupies in the storage space. Nondestructive compression is applied to this type of format as a ZIP file, making the scanned file about 2 times less space than a WAV file. Therefore, for 80 minutes of music on CD, the occupied space will be approximately 400 MB. Finally, this format is universal, compatible with most multimedia players, it is compatible with all operating systems except iOS,

Advantages: file size, identical reproduction of the original file during scanning, free and compatible with almost all media players and operating systems

– Disadvantages: none

ALAC: The ALAC (Apple Lossless Audio Codec) format is simply the Apple equivalent of the FLAC file.

– Lossy compressed files

MP3: The MP3 format (Mpeg Layer 3) is a well-known format. It is a format with destructive compression, that is, a recording from which musical information has been removed thanks to the so-called psychoacoustic compression algorithm (taking into account the peculiarities of the human ear), so that less scanning is needed to create a lighter file to obtain . This format is most commonly used for dematerialized music, as it allows a significant space saving in the storage space with a size of about 150 MB for an 80 minute CD. Compression can be more or less destructive depending on the speed used, which can range from 4: 1 (320 Kbits / sec) to 12: 1 (128 Kbits / sec).

-Advantages: it takes up little space on the hard disk and does not affect the quality of the songs with a dynamic range and a limited variety of timbres

– Disadvantages: paid MP3 license, destructive compression for “richer” songs.

AAC: The AAC (Advanced Audio Coding) format is a format close to the MP3 format, but provides additional definition with an identical compression rate. Apple uses this specific format in the iTunes Store, but also on YouTube. the extension can be written in various forms, such as .AAC, .M4A or MP4

-Advantages: better compression quality than MP3

-Cons: compressed file format at a loss
