MP3 vs FLAC: Which audio format is better for you?

If you like listening to music, you’ve probably heard of the MP3 and FLAC formats. Both are popular, but which one is best for you?

What is the MP3 format?

MP3 is a very popular audio format used to compress music files. This means you can have more songs on your phone or computer without taking up a lot of storage space. Plus, it’s easy to play on most devices, including phones, computers, and MP3 players.

What is the FLAC format?

FLAC is a lossless audio format, which means that no audio quality is lost during compression. This means that you will hear the music exactly as it was recorded by the artists. FLAC is ideal for those who value audio quality and want to hear their music with maximum clarity and detail.

What is the difference between MP3 and FLAC?

The main difference between MP3 and FLAC is the audio quality. MP3 is a compressed format that may lose some audio quality during the process, while FLAC is a lossless format that maintains all of the original quality of the recording. Also, FLAC files are larger than MP3 files, which means you need more storage space to save them.

Which is best for you?

It depends on your personal needs and preferences. If you want more music on your device and don’t mind a slight drop in audio quality, then MP3 may be the best option for you. If you are a music enthusiast and want to hear your music with maximum clarity and detail, then FLAC is the perfect choice for you.

FLAC vs MP3

With the advent of digital technologies in the world of music, the question arose about the choice of methods for digitizing, processing and storing sound. Many formats have been developed, most of which are still used successfully in certain situations. Conventionally, they are all divided into two large groups: lossless audio and lossy audio. Among the former, the FLAC format is in the lead, among the latter, the real monopoly was for MP3. So what are the main differences between FLAC and MP3, and are they really important to the listener?

What is FLAC and MP3?

If the audio is recorded in FLAC format or converted to it from another lossless format, the entire frequency spectrum and additional information about the file content (metadata) is saved. The file structure looks like this:

four-byte identification string (FlaC);
Streaminfo metadata (required to configure playback equipment);
other metadata blocks (optional);
audiofrems.
It is common practice to directly record FLAC files while playing “live” music or from vinyl records.

When developing algorithms for compressing MP3 files, the psychoacoustic model of a person was used. In short, during the conversion, those parts of the spectrum that our ears do not perceive or do not perceive completely will be “cut off” from the sound flow. Also, if the stereo broadcasts are similar in certain stages, they can be converted to mono sound. The main criterion for audio quality is the compression ratio – bit rate:

up to 160 kbit / s – low quality, a lot of third-party interference, frequency drops;
160-260 kbps – medium quality, mediocre peak frequency playback;
260-320 kbps – Deep, smooth, high-quality sound with minimal interference.
Sometimes a high bit rate is achieved when converting a low bit rate file. This will not improve the sound quality in any way – files converted from 128 to 320 bps will still sound like a 128-bit file.

To hear the difference between a quality MP3 and FLAC file, you must have an excellent ear for music or an “advanced” audio system. The MP3 format is more than enough for listening to music at home or on the road, and FLAC is still the plethora of musicians, DJs, and audiophiles.

About formats.
A little history. The MP3 format (MPEG-1/2 / 2.5 Layer 3) appeared in 1994. Do you remember those days? There was no talk of gigabytes, hundreds of megabytes cost a lot of money and many still remembered the legendary phrase of Bill Gates: “640 KB of memory is enough for any computer”. And if the veracity of this phrase is still questioned, then as early as 94 no one doubted that music would be distributed over the Internet, and the files would be stored on a computer. Okay, keeping your entire music library on one hard drive and being able to take it with you wherever you go is a great idea. However, at that time the main carrier of “digital music” was the CD.

A standard CD contains 650 megabytes or 74 minutes of music at a bit rate of 1411.2 kbps. In order to preserve a dozen albums in pristine quality in the year 94, it was required to have a very solid quantity! Yes, and a personal computer cost a lot then, and the main task of the MP3 that appeared was the ability to transmit sound through channels with little bandwidth. At that time, transferring an entire CD over the Internet required tens of hours at best. Therefore, the developers were faced with the task of reducing the size of the audio file to the maximum, avoiding to a minimum the losses during the compression of the signal. However, the encoding technologies were not yet perfect, and the processors were not that fast, so it was decided to apply the psychoacoustic method, in which only part of the audio information is lost. For example, all “quiet” sounds above 17 kHz and all bass below 40 Hz. The developers have established various levels of compression for such files, taking the digital stream as the basis for measuring the quality: the more information is transmitted per second of time, the higher the sound quality, but also the larger the file size. The maximum bit rate in MP3 is considered to be 320 kbps, in which the sound is balanced and the quality is as close to the original as possible.

And this is the “closest” and tormented to good sound lovers so far. The fact is that listening to music on high-quality equipment allows you to fully feel the difference between the original recording and its MP3 version, even at 320 kbps.

In all honesty, we admit that you can listen to music even at 64 kbps. If you just want to hear your favorite tune, then no obstacle is terrible. You can even play the nearest musical instrument yourself, if you have the skill, or listen through the speaker phone. However, if you want to enjoy a work in which all the inherent nuances and emotions, its interpretation by the sound engineer and the way the performers play, will be preserved, then MP3 (as, indeed, any other format of lossy compression) will. It will not be a joy, as the playback is excellent.Cd recorded and edited on a mediocre device.

The developers of the Flac format thought about how to reproduce high-quality compressed audio in high-quality Hi-Fi. In fact, FLAC (Free Lossless Audio Codec – “free lossless audio codec”) appeared only 6 years after MP3. However, encoding technologies have come a long way during this time, making it possible to create codecs that compress the audio signal without loss. Of course, it wasn’t possible to make the file smaller than MP3, but users now have an order of magnitude more spacious storage, so a couple hundred megabytes per album is a mere trifle. It is not?

FLAC vs MP3

Music lovers from all countries have been arguing for many years: is it possible to distinguish a high-quality MP3 from a lossless one in a blind test (FLAC, APE, etc.)? How much does compression loss affect the music experience? Should you give up MP3? Let’s try to answer these questions.

FLAC vs MP3 320 kbps
A little history

In the early 1990s, experts understood that the future of music was digital. However, hard drives were expensive then and fans preferred to store their music collections on cassettes and CDs. The researchers faced a problem: they needed a suitable format to store records on computers. At the same time, they were counted every hundred kilobytes – you can slightly sacrifice quality compared to CD discs, but save precious hard drive space.

In the late 1980s, the first functional prototypes of a new lossy compressed audio storage format, MP3, were created. The first publicly available MP3 encoder appeared in 1994, and the first playback software soon followed. The first encoding algorithms made it possible to obtain files with slightly “chopped” high frequencies. The sound quality was not comparable to that of a CD, but the output file sizes were quite acceptable.

In the early 2000s, the sizes of hard drives were growing rapidly and other audio formats that provide lossless compression began to appear. Relatively speaking, an audio track in this format can be restored to its original WAV from a lossless CD. Perhaps the most popular lossless compression format was FLAC, introduced in 2001. It is suitable both for storing home audio collections and for playing music on professional computers. However, a FLAC file can be 6-10 times heavier than a good quality MP3 (256 or 320 kbps). But does file size and losslessness mean consistently high sound quality?

A bit of anatomy: The human ear is theoretically capable of hearing sounds from 16 Hz to 20 kHz. However, much depends on the age and individual characteristics of the listener. The author of this article can hear sound with a frequency of 16 kHz, but not 17 kHz and above, but there are adults (25 years and older) who can still perceive 18 kHz. All of these frequencies are quite successfully supported by the MP3 format. If you are exceptionally clear, you will be able to hear some difference in the high frequencies, but the difference is almost subtle for most people.

Even if your favorite song in the spectrogram is clipped to 20 kHz, you won’t hear any distortion (unless of course you’re 8 years old).

The vast majority of people cannot, for natural anatomical reasons, distinguish between high-quality 320 kbps MP3 and FLAC (as long as both digital recordings are obtained from the same source). Of course, if you compress more MP3, for example, up to 96 kbps, the difference will be clearly audible even with cheap headphones. But in the age of terabyte drives, no one listens to music with such compression.

Of course, the equipment used for listening has a significant impact on the perception of music. It is impossible to listen to all the high frequencies in the recording of a symphony orchestra on headphones for 300 rubles, even if you have wonderful hearing and a high-quality recording. However, many specialists are dedicated to mixing music, taking into account the capabilities of the most popular audio equipment among consumers. Bill Ward (Black Sabbath drummer) said that while working on his solo album Accountable Beasts (2015), he first tried to achieve a clear and distinct sound from each note, but then realized that almost all listeners would use inexpensive equipment. and they wouldn’t hear all tones and halftones. As a result, Bill bought several relatively inexpensive headphones from a nearby store and mixed the album in them.

In the case of a file obtained from the Internet (even bought honestly), it is extremely difficult to understand which input was the original source. The sound quality of a file obtained by digitizing vinyl or CD (with or without remastering) will differ from a quality recording of Internet radio broadcasts, although all files can have the same bit rate.

Thus, we come to an obvious conclusion: the difference between high-quality MP3 and high-quality FLAC will only be heard by a trained music lover (most likely young, since after 40 years the range of audibility is reduced ). In addition, you will need quite expensive equipment to appreciate all the characteristics of the sound.

Placebo effect? Can you distinguish an mp3 320 kbs vs a FLAC?

Studies have shown that most people can NOT distinguish an mp3 at 323 kbs (That is, with the best quality) from a FLAC file.

MP3 vs FLAC

We all know that in theory an mp3 is a format that discards information to achieve a small size; or, indeed, due to this ability to take up little space on the disk, but sounding very similar to the original wav was what propelled fame to mp3.

The Mp3 is dead.

Dozens of times it has been written about the undeniable advantages of the formats that do not lose information (looseless), it could be thought that people would turn their backs on the mp3.

MP3 vs FLAC

Some have warned that it is not so likely that this will happen, since most of the audio players (for example, those that come from the factory with the cars) play mp3s but not Flac.

Placebo effect?

But others have pointed out that untrained human hatred CANNOT distinguish an mp3 recorded at its highest quality from the FLAC.
For which to show yourself as a lover of FLAC and a fanatic defender of that format, it is more a snobbery full of blah, blah blah and technicalities that ignore that the human ear is not a robot and that in reality most people they cannot distinguish between one and the other.

And we combine the convenience of using mp3s because the devices are designed for mp3 and not for FLAC, together with the fact that in reality most people cannot distinguish one from the other … this should explain that that the mp3 is dead, is more a product of fanaticism than realism.

Also, they forget another problem.

When digital music is recorded it requires using a compressor … which did not happen with music recorded on tape, that is, vinyl.

That is why there is another faction that does not proclaim and sing songs in favor of FLAC but rather the return to vinyl (forgetting all the advantages and comforts of digitization).

In other words, all these discussions seem more like a mixture of snobbery and puritanism than something realistic.

What studies have shown

What we cannot ignore is that undoubtedly 99% of people (including many experts, musicians, etc. who talk hours about bitdepth, bitrate, etc.) can NOT distinguish a WAV, from a FLAC, from an mp3 recorded at qualities superior to 160 kbs.

Personally, we celebrate that all these formats exist and that we are coming to the time where every person can use and love the format of their choice and even defenestrate and even hate other formats and discuss long hours about their technical knowledge.

But yes, it seems that it is basically a placebo effect.

Flac vs Mp3, differences

In today’s world, it is important to understand the difference between the different audio files available.

The most common and current files are practically the files in the formats MP3, Flac and WAV.

Is there really a difference between MP3, Flac and WAV files? The answer is absolutely yes.

The difference is in the audio quality that these files can play.

What is the difference between MP3, Flac and Wav files? MP3 files are of lower quality because they are more compact and smaller. Flac files are a kind of compromise. With files in Flac format, it can be of very good quality and remain true to the original, which in any case is compressed by a certain percentage. Finally, there are the WAV files that do not use compression.

Therefore, the quality is better, but the size of these files is quite large, it is not compatible with any device these days.

It may not be easy to understand which audio file to use for your work, especially if you are a beginner in this area.

However, you don’t have to be afraid of it.

Once you’ve learned all the differences between the three audio files, you can really fix the problems by always using the appropriate file.

What are the differences between the categories in detail and when should you use a specific audio file?

Here’s a complete analysis for each audio file format that really helps you understand everything you need to know about MP3, Flac, and WAV files.

What is an MP3 file?
It starts with one of the most common files in the world of information technology, namely the one called MP3.

MP3 files have been around for years, so their development is common.

But what an MP3 file really represents.

Well, a general audio file is a series of numbers obtained by sampling the analog signal.

This scan responds to some parameters, which are the frequency measured in Khz and the resolution expressed in bits.

The MP3 file represents the most compressed form of an audio file, so to speak.

Finally, you need to understand that the MP3 file can remove all unnecessary parts of the digital file from the sequence and the final sampling, taking advantage of some imperfections of the human body to give it a clear and clean melody.

On the other hand, the MP3 file significantly reduces the quality of the sounds played.

In fact, all the different nuances of a certain melody come to the bone.

An MP3 is small if you speak it from the perspective of the memory. You should think of it as a kind of concentrate that gives you a remarkable but not 100% complete end result.

In the most extreme cases, an MP3 file can reduce the original tones and nuances of music or melodies to a percentage of 90%.

However, these formats are widely appreciated and used because they are not only practical and direct, but are now compatible with all technological devices, e.g. B. MP3 players, for which we recommend that you read our guide.

This means you can take them with you at any time and any product you have can read an MP3 file.

What is a flac file?
So at this point you need to understand what a Flac file is.

Well, it should be said that the Flac file has some major differences from its MP3 counterpart.

In fact, a Flac file is much more complex than a regular file and can be reduced by 90%.

First, you need to understand that Flac is actually an acronym that stands for Free Lossless Audio Codec.

It is always a format that is somewhat compressed, but files with this name have a certain property.

In fact, the file is lossless with no loss and maintains higher fidelity than the original sound.

With a Flac file, you have a clearer quality of the audio file, so you can clearly hear some details that can be lost if you use a different audio format.

The limited storage space when using the Flac format is very small and can reach a maximum of 50%.

However, when using such files, you should be aware that their use on the storage hard drive is important.

Not surprisingly, Flac files take up a lot more space than regular MP3s. In some cases, a special reader must be downloaded to read them. Many home theaters and receivers support this compression format.
