What is a “FLAC file”?

FLAC

Introduction to FLAC.

Free Lossless Audio Codec FLAC

The base of the music files are the “Wave files”. If you draw a music file from a commercially available CD, it will be saved in this “Wave file” format. Therefore, this “Wave file” is the best in terms of sound quality.

However, the inconvenience is that the file size is very large.
Generally, “1 minute = 10 MB”, so even a small element of about 5 minutes will be “50 MB”, and a 1 hour masterpiece symphony will be “600 MB”.
When I try to download such a large file on a thin line in the first days of the Internet, it does not end, even if it takes hours (days?). (It is still difficult for “600MB” files ^^;)
Even so, the desire to share music widely through the Internet created a compression technology called “MP3 files”.

I will omit a difficult explanation, but the good thing about this “MP3 file” was that “reduced the deterioration of sound quality as much as possible” and “reduced the size of the file”. Now, even if the file size is reduced to 1/10, you can enjoy music with a sound quality that is not very different from that of a CD.
In other words, even if the file size is reduced to “5MB” for a small element of approximately 5 minutes, or “60MB” for a 1 hour box office success symphony, you can now enjoy music with a quality of Sound that is not very different from that of a CD.

It’s really great.

However, there is a difference in sound quality when compared to the grave.
With the growing interest in PC audio these days, more and more people pay attention to this sound quality. For those who say that, it is “natural” reproduce music in “Wave files” instead of “MP3 files”. In fact, due to the pc audio boom, the software that can only be played Wave files is appearing one after another. “CMP2 = CMP + CPLAY” and “WAVE FILE PLAYER” are typical examples, and high-quality sound playback that distinguishes it from conventional playback software is on sale.

Well, I do not care … if you say it, pass this page. (^^;

Weaknesses of MP3 files → irreversible

MP3 files are a really good technology. By compressing the size of the file to 1/10, it maintains an excellent sound quality so that you will not notice the difference with the original “Wave file” if you listened vaguely. Then, as I mentioned earlier as a joke, it is not surprising that some people say: “That is enough for the quality of the sound!”
It is such a good technology.

However, these “MP3 files” also have a fatal weakness.
That is “irreversible”.

It is difficult to say “irreversible”, but the point is that once a “Wave file” is compressed in an “MP3 file” and it becomes, you can not restore the original “Wave” file. It is about nature.
This “never return” property is called “compression with loss”, and compression with said property is called “compression with loss”.

However, you may be told: “If you decode the MP3 file, it will return to the Wave file!”
Usually, the conversion of the original file into a compressed file is called “encoding” and, in reverse, the conversion of the compressed file to the original file is called “decoding”. · · · Trivia (^^ V
Certainly, MP3 files can be converted to WAVE files using the appropriate software.

However, keep in mind that the “Wave file” created when decoding the “MP3 file” is not the same as the original “Wave” file. This is because the deterioration of sound quality caused by the first compression is not recovered and becomes a WAVE file in a deteriorated state.
Specifically, the “MP3 files” eliminate the high tone information that is difficult to listen for the human ear in the compression process. Therefore, even if you decode the “MP3 file” compressed in this way, high-frequency cut information will not be recovered.
Therefore, if you do something stupid as Wave-> MP3-> Wave-> MP3-> Wave …, the sound quality will deteriorate and you will end up in a “is not what you heard”.

What is really … FLAC?

FLAC (Free Lossless Audio CODEC): Unlike lossy formats like MP3 or the lossless AAC method of storing audio files. Any audio enthusiast who values the highest quality of their digital music collection should consider saving their tracks in FLAC format.

FLAC vs MP3

FLAC vs. MP3: lossless and lossy

As you can read from the English name, FLAC is free and lossless audio compression. Everyone knows the audio compression principle of the MP3 file format. On a commercially available audio CD, a typical three-minute song takes up around 30MB, after conversion to MP3, on average only about one-tenth of that, or 3MB.

Lossless FLAC Audio

The reduction is very high, especially noisy, and consciously non-perceptible parts of the original signal are lost, which is hardly a restriction for listening pleasure. However, it is never possible to calculate exactly which parts are really irrelevant to the listener, so useful information is also destroyed during compression – the quality decreases compared to the original.

This is where FLAC comes in. This codec does not compress the audio signal according to psychoacoustic methods, but rather mathematical ones. Although FLAC has a relatively low compression rate (on average, the above-mentioned three-minute track in FLAC format would be around 15MB in size), the quality is exactly the same as the original CD. The fact that the file size can still be reduced is due to the fact that musical signals contain redundant information from a mathematical point of view due to their high periodicity. Therefore, FLAC is perfectly suited to digitally archive your lossless CD collection.

How can I play FLAC files?

Common audio players can play FLAC files. In addition, more and more audio devices, such as AV receivers or Blu-ray players with USB or network connections, can play not only MP3 but also FLAC. Teufel’s audio transmission systems also reproduce the format flawlessly.

Finally, the small drawback: CD files in FLAC format quickly get very large. With 100 CDs, you get a storage requirement of around 40GB, while the same number as an MP3 file only takes up about 7GB. But if you have a superior (diabolical) system at home, you will quickly appreciate that you are hearing exactly what the music producer had in mind when the recording was made: an impressive listening experience with no compromises.

Conclusion: is FLAC the audio format of the future?

FLAC is a format that compresses audio data without loss. So it is qualitatively equal to CD.
FLAC files are as easy to create as MP3s, but they take up much more space than MP3s.
The audio format is ideal for digitizing CD collections and adapting them to the future.

FLAC or AAC? Find out which audio format is the best

With the “death” of MP3, formats like FLAC and AAC gain more space.

Music consumption on current devices may involve the use of non-MP3 files, as the creators of the format are abandoning their licensing program. Among the new types of audio files that have gained space are FLAC and AAC. With different proposals, they serve broader but conflicting usage and consumption profiles: FLAC is for those who demand the highest quality, giving up space, since the files tend to be large. AAC can be seen as a more conventional option: small file sizes, but with better sound quality than the previous MP3.

MP3 vs FLAC vs WAV vs AAC

Audio formats are divided between lossless (maximum quality) and loss, compact quality and lower

Understand the points that differentiate between FLAC and AAC files to find out which format best suits your needs.

Lossless and lossy audio

Digital audio file formats are divided into two types: lossless (lossless) and lossy (where, conversely, there is loss).

Flac vs AAC

The main characteristic of a lossless file, such as WAV or FLAC, is the fact that the sound stored in the package is faithful to the original: that is, in the process of converting the CD track, all the information has been preserved sound related to the song. completely, without any loss, ensuring high fidelity to the file. The problem with this is that the result is a large file – a WAV track can be over 40MB.

Lossy format refers to an approach in which the conversion of the original audio to the final file (MP3, AAC and etc.) goes through a compression process in which a variable amount is removed (depending on the chosen bit rate ) information to ensure a smaller file size. In the case of MP3, the ratio is 10 to 1: a 40 MB WAV returns a 4 MB MP3, at 128 kbps.

This information, removed in lossy type conversions, is generally automatically defined by the conversion software based on theoretical precepts related to the frequencies that our ears can identify. The problem with this approach is that there are ears and ears, there are sound devices and devices, and there are songs and songs: some details of the songs can be removed in an MP3 or AAC because the conversion ignores them.

And what is bitrate?

Not all AACs and MP3s are created equal: a low bitrate file will be of much lower quality than a higher bitrate version.

Simply put, it is the amount of information that is executed in a certain period of time when you listen to music. If the file is 128 Kbps, it means that 128 kilobits of information are executed every second. If the file is 320 kbps, it is 320 kilobits per second. The higher the value, the larger the sample, and generally the higher the sound quality of the file.

FLAC: lossless audio

FLAC-type sound files are converted to original using a compression process called lossless. This testifies that the compression of the music on a CD, for example, does not represent loss of information: the sound quality faithfully represents the experience of listening to the same track from a medium.

The point is that the FLAC format ends up “charging a high price” for all that quality. First, files get bigger (a single song can be over 20MB in size), which restricts the number of tracks you can store in a player and makes it difficult for anyone who consumes music to stream with Tidal: The weight of the file It can consume your plan and represent a bad experience, if your connection is slow and it is necessary to interrupt the playback to load the song.

Also, in general, the user does not have sound reproduction equipment that really takes advantage of the high quality of the FLAC without losses. Using low-quality headphones, along with inferior media players, can eliminate the benefits of higher quality lossless files compared to MP3 or AAC.

Which is better, after all?

If you value sound fidelity, you have good audio equipment and disk space is not a problem, lossless format is the best alternative: FLAC, ALAC and APE guarantee the highest audio quality. In this scenario, the discussion about AAC loses its meaning, since the gain will only be in the file size, but with loss of quality.

However, the AAC is a good option for those who don’t have high-quality headphones or sound systems. AAC is even a great format for users who have amassed a large, low-bit-rate MP3 library at 128 kbps. If you don’t have good equipment and good headphones, the FLAC is superior.

FLAC versus MP3: Does it make sense to use a “lossless” audio codec?

Free Lossless Audio Codec (FLAC) is an audio format that is unknown to the public, but is particularly loved by the most demanding audiophiles: unlike MP3, AAC and their partners, FLAC is lossless, which means that it compresses audio with no loss of information. The advantage is the superior quality and the certainty that a 1: 1 copy of the original can only be made from the files. The disadvantage is that the tracks “weigh” significantly more. Is it a winning engagement or not?

Let’s go to the conclusions

If you have original, rare and / or valuable audio recordings that you want to keep indefinitely for years (even if the original media wear out), FLAC is the optimal choice.

But if you only make it a matter of quality, think twice about it: it might not be worth it.

Never convert from MP3 to FLAC – it would take up extra space for free.

FLAC is … an audio codec

Let’s start with FLAC being an audio codec: that is, it is used to compress music or other sound sequences so that they take up less space than storing the same information directly.

To get an idea of how basic this is, keep in mind that an hour of uncompressed audio (no video) takes 620MB.

FLAC is … “free”

Then there is the word “free” which should be interpreted as “free” and “free”. FLAC is distributed in open source mode (GPL license). This means that its specifications can be used by anyone without paying any commission.

In contrast, there are MP3s that must be used within software and device manufacturers by Thomson Consumer Electronics and the Fraunhofer Society.

FLAC is … lossless

The third aspect concerns the type of compression used. While MP3 and AAC reduce the weight of the file by permanently eliminating frequencies and nuances that are generally unrecognizable to the human ear, FLAC retains every last bit present in the source and then applies only a number of specific optimizations, before the file is saved result in reducing the size on the hard drive. When the file is opened, however, the process is reversed and FLAC returns the original audio perfectly.

The procedure is similar in many ways to that of compressing in zip format: when the file is unpacked, we get the perfectly preserved initial file again. The difference is that FLAC was specially developed for working with audio and significantly reduced the size of the source file.

Lossless = quality + flexibility

Audiophiles complain that the “cuts” in the MP3 codec are too heavy and that the quality is unacceptably affected. In contrast, the performance at FLAC corresponds 100% to the original “master”.

Added to this is the aspect of optimal data storage: FLAC supporters point out that a “ripped” CD in this format can later be recreated from the files themselves and that a bit-by-bit result is achieved that corresponds to the original. However, the same procedure used for MP3 extraction would produce a different, lower quality disc.

The disadvantages: size and compatibility

The disadvantage is that FLAC files in megabytes are much heavier than compressing them with MP3. Although the actual efficiency depends on the sound characteristics of the respective source, an average reduction of 40-50% can be expected: For example, an hour of audio ranges from approximately 600 MB of the uncompressed format to 300 MB in the optimal case

With MP3, compression is much more intensive – the same hour of compressed audio at 160 kbps (or very high quality anyway) is expected to be around 70 MB.

Then there is the compatibility problem: MP3 is natively compatible with any Smart TV, radio, PC, smartphone or media player that is still in circulation. FLAC, on the other hand, can only be played natively on Android, Linux and Windows 10. On the other platforms, if possible, you need to download a dedicated player or convert songs in advance.

Better 16 bit or 24 bit? Which audio sampling rate should I choose?

Record 16 bit or 24 bit, what changes?

Today we live in the middle of the digital age, which has made the total distribution of music possible. Thanks to this, we can download an entire album “free” from the Internet in a few minutes. The benefits of the digital age were really impressive, but today we’re not going to talk about it, but rather focus the discussion on what the ideal recording is, choose between 16 bit or 24 bit and identify the sound differences between the two registration modes with the case’s various useful tips . The times when everything was recorded in analogue are far away. Think of the sound of Pink Floyd’s “Dark Side of the Moon”, “In the Court of the Crimson King” by King CrimsonO, Lonely Hearts Sergeant Pepper’s club band by The Beatles.

We live in a time when digital is the master, but it is true that analog resists and can offer much higher quality. Let’s see what the differences between these two recording modes are between 16 and 24 bit. Before we start the decision with rather challenging speeches, we need to know what the word “bit” means, which indicates the amount of information in each sample and describes its resolution. Let us take a few explanatory examples: 16 bit is the sound depth used on audio CDs, while 24 bit is the definition of audio that can be achieved on an audio DVD. Now think about it: The CD generally has a storage capacity of around 700 MB instead of a 4.7 GB audio DVD, okay?

How are the audio files played?

We can say that a set of digital information is converted into an analog signal, which allows the sound waveform to be reproduced. Among the advantages that we undoubtedly have for an absolutely perfect sound cleaning, the digital audio file takes up considerably less space than the analog one, or rather we can determine the size of the file that we want to record or capture.

Let’s start with the recent past, when the widespread frequency on compact discs was 16 bit and 44,100 Hz, all albums and collections were recorded on audio CDs. This limit began to exceed thanks to the launch of new devices. Like drum machines, for example, the bits began to gradually increase from 16 to 18, 20 to 24 bits.

Today it is evident that an audio interface can work with 24 bits, including other alternatives to the recording mode, which can be performed at frequencies of 44.1, 48, 88.2, 96 to 192 kHz. Digital systems convert an analog signal to a digital format to store and transmit data using PCM (pulse code modulation). This quality is given by two factors, the first being determined by the bit depth and the second by the recorded frequency of samples. The first factor, bit depth, indicates the number of bits used that quantify the number of levels that characterize a tone in a second. In other words, the more bits a sound has, the more it is defined in level (for example, 16,536 levels are available per second for 16-bit recording.) We can say that the higher the sampling frequency, the more the sound area becomes defined, with the result that the transformation of the signal from analog to digital would be more accurate.
That means we can conclude with one consideration, ie the greater the bit depth, the greater the sampling frequency and the more audio information is stored, the more defined the audio quality. The development and continuous search for effective systems is a subject in which many studies are carried out.

Now we will delve deeper and deeper into our discussion by analyzing the different modes of audio resolution that enable sound quality and size. Suppose the larger the sound you want, the larger the file size.

What are Flac files?

FLAC is an acronym that stands for Free Lossless Audio Codec. As the English terms indicate, this literally means that it is a type of coding with which a signal can be read and written without data loss and which differs from the “lossy” types (Ogg Vorbis, MP3 or AAC). FLAC was deliberately designed and developed to compress audio files, which was not the case with other encoding types such as ZIP and gzip. For this reason, significant compressions can be achieved, which can be reduced from 30 to 50%

What are Flac files?

For some time now, people have been hearing about Flac files. But what are these ghost files and what are they for? If you read the following, you will have a clearer idea and the basis to delve into the matter.

Music, especially for the needs of broadcasting through the Internet, has been subjected to compressions, sometimes even violent, with specific algorithms, of which the best known and most used is MP3. This compression is capable of dramatically reducing the size of the part and unfortunately also counteracts the quality, while ensuring an acceptable quality reproduction. This sound treatment is called “lossy”, that is, with loss of information compared to the original.

waveform mp3 and flac

The search for the quality of listening shocks with this treatment ensures that you can store large amounts of musical pieces in small spaces, but at the same time makes listening less “exciting” and mortifies the commitment of musicians and sound engineers. So what can we do to have listening quality, easy storage and archiving? just use Flac encoding.

Flac stands for Free Lossless Audio Codec. By reading the definition well, we learn that it is:

Free: means it can be used at zero cost; The specifications of this format are open source, that is, free to use and are not covered by a patent that would impose the payment of royalties to the owner.
Lossless: Compression with this system is free from loss of audio information, therefore it means that the copy is gradually identical to the original and therefore the listening quality is preserved.
Files encoded in this way can be played on a wide variety of platforms, including PCs, home hi-fi systems, portable players (often called DAPs, short for Digital Audio Player), in the car, and more. Currently, DRM is not implemented, that is, there is no copy prevention method. This standard also supports labels that include cover images.

At this point a series of questions arise:

How can I create Flac files?

Files can be created from a software encoder installed on your computer. The best known is Mp4Gain, a program that additionally allows you to normalize the audio volume.

Can I buy Flac files?

Yes, you can buy Flac files online on the web at specific sites. The feature of these sites is that it can provide some artists with high-resolution encodings that can be up to 4 times higher than a CD – virtually the quality of the original Master recording!

How can I play Flac files?

Files can be played with devices that support this encoding: personal computers, hi-fi systems, portable digital players, and car audio sources. You should read the product specifications and make sure they are compatible.

What are the advantages over an MP3 file?

The quality, above all, equal to that of the original CD from which you made the “Audio Recording” to the high resolution similar to the original master of the recording room.

What are my disadvantages compared to MP3?

The file size, clearly larger. The limited diffusion to date of compatible players with the Flac.

Compared to a CD, what are the strengths and weaknesses of Flac files?

The strengths compared to a CD are the consistency of the quality of the file encoded in Flac, the CD is influenced by a series of variables, the state of wear of the reading lens, vibrations, humidity of the environment determine an intervention Systems to correct errors that affect listening quality. The Flac file, once carefully encoded, will always offer the same listening quality after listening as it cannot be influenced by the factors mentioned above. Storing a large number of tracks is very easy: portable HDs are small in size and very easy to transport. The same number of tracks stored on CDs would be difficult to handle, especially in the car. The weak point is undoubtedly the ease of use: CD players are widespread in all environments, home.

Audio quality in different formats (flac vs. mp3)

In this post I am going to talk about what differentiates music from mp3 and flac. First, and before you begin, go ahead with the following:

The quality of a musical hearing depends (and a lot) on the audio card and the musical equipment (amplifier, headphones / speakers) used, and on the other hand it also depends on the sensitivity of one’s ear. A newborn with perfect hearing can hear from 20 Hz to 20,000 Hz. The normal thing for a young person is to hear nothing above 18 kHz, although some people with exceptional hearing can hear 20 kHz or even more. , and a person 25 years of age or older begins to lose hearing from 15,000 – 16,000 Hz. In addition to the frequency response (quantitative aspect), the qualitative aspect is equally or more important: that the waves at each frequency are produced in the most similar way to the original source.

Having said that, we fully enter the subject at hand.

Many people think that an mp3 sounds like the quality of a CD. This is not exact. Apart from the fact that a CD sounds with the quality that those who have recorded it have given it, mp3s are formats with loss, and that means that a good part of the original information is discarded to save space. The trick is that the information that is discarded is, as a rule, information that is “hidden” among the rest of the information. To give a simple example so that the idea is understood, if a person is speaking to me at a normal volume and suddenly a helicopter passes in front of us, the sound of the helicopter will eclipse in my ears the voice of that person; the wave of his voice will continue to reach my ears but I will not perceive the sound. Another example, so that I am also understood: if we could play two very similar pianos at exactly the same time in such a way that their vibrations coincided, the mp3 would “say” that “one of the pianos is left over”. This type of operation (but, of course, at a much more subtle level, of microscopic changes) is what is done so that the initial 40 or 50 MB that a song occupies on the CD are reduced, at most, to 9 MB or less, depending on the bitrate (128, 160, 192, 256, 320 kbps) of the mp3.

But all that information that the mp3 removes at a stroke is information that, from the original source, would reach us, and it is information that would affect us emotionally (an mp3 violin can hardly give us goosebumps), although consciously most of the time we do not know how to express the difference in words. The same happens, for example, when a person is recreated in virtual reality: sooner or later we will know that this person is not real, because virtual reality technology has not yet managed to recreate the microscopic details that we are capable of capturing and that make us identify a person as real and not virtual.

Other differences between an mp3 and a wav (Microsoft’s uncompressed wave file) or a flac (Free Lossless Audio Codec, free lossless audio codec) are noticeable after spending a long time listening to music. The mp3 ends up giving you a headache, while the original sound doesn’t. And to this we must add that there are certain songs that have the musical information arranged in such a way that the mp3 algorithm is not able to “guess” what it is that you are not going to be able to listen to, and the result is that there is a notable loss quality, especially in the treble. In fact, a 128 kbps mp3 cuts all frequencies starting at around 15 kHz, and this is something that most people with normal hearing can easily perceive.

So that you can hear the REAL differences that exist between the different audio formats, I have prepared several tracks in which I have done the following:

1) I have loaded the song from the original disc.

2) I have recorded it in different formats: flac, mp3 to 128, mp3 to 160, mp3 to 192, mp3 to 256 and mp3 to 320 kbps.

3) I have then loaded all the waves into the Sound Forge Pro 10.0 program.

4) I have synchronized all the waves bit by bit. This is necessary because the mp3 introduces a certain lag of milliseconds with respect to the original.

5) I have copied each mp3 wave (lossy quality) and mixed it on the flac wave (original quality, without loss) with the reverse polarity. If both waves were identical, the result would be silence. But instead, as the mp3 has less information (the wave has fewer resolution points, so that it is understood) there is a residual noise that corresponds, neither more nor less, to what the mp3 has less than the flac added to what the mp3 has more than the flac (the mp3 not only loses information; it also introduces noise that was not in the original recording).

6) I have recorded everything on flac. Contrary to what most people think, the fact of converting an mp3 to a higher quality format does not add quality, since the additional information “cannot be invented” by the mp3, and it is still absent. An mp3 transferred to CD continues to sound like an mp3.

Important note: In order to listen to the files, your player must be able to play flac. First of all, associate the files with the .flac extension to your player so that it opens them when you click on them. If they still don’t sound, then install the necessary codec or plugin.

As a player I recommend the AIMP2 or the Foobar2000; both are free and give exceptional audio quality (they reproduce the sound as it is recorded, without any attachments of any kind). For my taste, the best of the two is the Foobar2000, because it is also more stable and lightweight. The Winamp and the Windows Media Player color the sound (or in other words, they equalize it), which can be interesting if you have low-quality audio equipment and play mp3s at low bitrate (128 kbps), but, If the equipment is hi-fi and the music is encoded in a lossless format or played directly from the original CD, then the difference between Winamp or WMP and AIMP2 or Foobar2000 is quite noticeable.

Lossless audio formats

We will show you the formats that maintain all the quality of the audio files, compressing just enough. Lossless formats tend to maintain the original quality almost totally, suffering a minimum loss of quality. In summary, they are slightly compressed so that the audio remains intact and the size on disk is smaller.

Among the Lossless formats we have:

FLAC, is a format whose algorithm is similar to ZIP or GZip, but specially designed for audio compression. While ZIP would compress a CD quality audio file from 10% to 20% of its original size, FLAC would compress it from 30% to 50% while maintaining the full quality of the source.

Monkey’s Audio (APE), like FLAC allows lossless compression, but the greatness of Monkey’s is that it compresses bit by bit, reaching data rates of up to 700kbps without any loss of quality.

Apple Lossless (ALAC) uses an MP4 container (with a .M4A extension) for its files just like the MPEG-4 AAC and is specially created for use on the iPod.

Shorten is another Lossless format with characteristics similar to Monkey’s Audio or FLAC, but using the .SHN extension and requires fewer resources for its reproduction.

WavPack uses a hybrid mode, unlike the other Lossless formats, since it uses a Lossy file, which creates a relatively small file at high quality, and a corrector file that recovers the remaining quality of the original file, resulting in an audio file at averages between Lossless and Lossy, but with the same quality as a compressed file with any other Lossless algorithm.

TTA (True Audio) is a free and free LossLess format that reduces by 30% the original size of the source audio file and uses compression / decompression in real time.

What are the advantages of listening to music in FLAC format?

The FLAC format allows us to save audio without loss of quality. This codec encodes the file with the same information that the original CD would have (which would be the WAV file).

It is an open source format (Free Lossless Audio Codec) that could be improved, thanks to its registration as an open source license.

Higher quality, especially for HiFi equipment: this format allows us to enjoy a bitrate between 900 and 1100 kbps that does not delete information as it does in the MP3, even if it is of high quality. You will notice a warmer, fuller and cleaner sound.
The information is continuous between tracks: just like on the original CD, you can listen to music without interruptions between tracks.
The music is not altered: and that is the main reason why FLAC is ideal. Well, the file you use is the same one that you would download from the CD.
The FLAC format supports unlimited sampling rates – a FLAC can reproduce frequencies of 192,000 Hz without problem.
However, all that it reduces is not gold. There are also some problems with FLACs that you should be aware of, although they are not serious at all.

Disadvantages of listening to music in FLAC format

They take up more: as a FLAC file usually takes up a little more than half of the original CD file. It is easy for an album to go to 300 MB.
Many players do not support FLAC – this is changing in a beastly way. But the industry has fought for the MP3 to the last breath and many players, radios, etc. do not yet support this standard.
That is, the disadvantages are or rather were. In the future we will have a new cleaner format, which will surely take up less space and be an evolution of FLAC. Currently, however, it is the format par excellence and the one that we should all use, although I am not sure that a new, closed format will not come out, that can cope with it before it reaches its peak.

What is FLAC?

FLAC which is short for Free Lossless Audio Codec is an audio codec developed by the Xiph Foundation. Nonprofit org. It is a lossless audio format, which means it produces digital audio files (with a .flac file extension) that are identical to the original source.

In fact, many users who want to back up their original audio CDs (ripped CDs) choose to use FLAC to preserve sound instead of using a? Lossy format.

Doing this ensures that if the original source is damaged or lost, then a perfect copy can be reproduced using the pre-encoded FLAC files.

Of all the lossless audio formats available, FLAC is perhaps the most popular in use today. In fact, some HD music services now offer tracks in this format for download.

Nowadays, listening to music in high definition is no longer a luxury and has become almost a requirement. There is nothing like hearing a song as the artist decided it should be heard. Due to this, various technologies have been developed that allow us to enjoy Hi-Fi audio. Among them are some audio formats, such as FLAC.

Before explaining what the FLAC format is, you need to understand a technicality:

What is bitrate

It is the bit rate, that is, the amount of bits or data that is processed in a given unit of time.

In the case of audios, the measurement of kilobits per second is normally used. For example, if you see that the music is in 256 Kbps quality, it is understood that there are 256 kilobits of information stored in every second of the song.
