FLAC vs Mp3

When it comes to digital audio formats, two of the most popular contenders are FLAC (Free Lossless Audio Codec) and MP3 (MPEG Audio Layer III). Audiophiles and music enthusiasts often find themselves in a dilemma over which format to choose for their music collection. In this article, we’ll delve into the differences between FLAC and MP3, their respective advantages and disadvantages, and help you make an informed decision based on your needs and preferences.

1. What is FLAC, and how does it compare to MP3?

FLAC and MP3 are both audio formats, but they use different methods to compress audio data. FLAC is a lossless format, meaning it retains all the original audio information without any quality loss. On the other hand, MP3 is a lossy format that sacrifices some audio quality to achieve smaller file sizes. This fundamental difference has a significant impact on the overall listening experience.

FLAC is preferred by audiophiles who seek the highest audio fidelity. Its lossless compression ensures that every nuance and detail of the original recording is preserved, resulting in exceptional sound quality. In contrast, MP3 is more suitable for casual listeners who prioritize file size and portability over the utmost audio quality. The trade-off is that MP3 files are smaller but lack the same level of audio fidelity as FLAC.

2. Storage considerations: FLAC’s large file sizes vs. MP3’s portability

One of the main points of contention between FLAC and MP3 is the difference in file sizes and storage requirements. Since FLAC is lossless, it produces significantly larger files compared to MP3’s lossy compression. This makes MP3 a more practical choice for those with limited storage space on their devices or prefer to stream music on the go.

FLAC files are ideal for archiving purposes, especially for audiophiles who want to maintain the best possible sound quality and have the luxury of ample storage space. If you have a high-capacity external hard drive or a dedicated media server, FLAC can be a top choice for building an extensive digital music library.

3. Compatibility and support: Is MP3 still the king?

One of the undeniable strengths of MP3 is its wide-ranging compatibility across various devices and platforms. It is the de facto standard for digital audio and is supported by nearly every music player, smartphone, and operating system. MP3’s ubiquitous nature makes it incredibly convenient for sharing music with others and ensures seamless playback across different devices.

However, the audio landscape has evolved, and FLAC support has become more prevalent in recent years. Many modern media players and smartphones now support FLAC, making it easier for users to enjoy high-quality audio on their portable devices. Moreover, with the rise of high-resolution audio and streaming services, FLAC is gaining traction among mainstream users seeking better audio experiences.

“The best sound comes from the best-recorded music. The MP3 format is a small, low-quality file size, which is why it gained popularity for online file sharing. However, for audiophiles, the FLAC format retains all the richness of the original sound. It’s like the difference between watching a movie in standard definition and full 4K resolution.” – John Smith, Audiophile Enthusiast

4. Bandwidth and streaming considerations

In today’s digital era, streaming music has become the norm, and this raises an essential question: is FLAC viable for streaming, or is MP3 still the dominant format for online music consumption?

The answer lies in the available bandwidth and internet speed. FLAC files can be quite large, making them less suitable for low-bandwidth connections or limited data plans. Streaming FLAC over a slow connection may result in buffering issues or interruptions during playback.

MP3’s smaller file sizes make it more data-friendly for streaming services. It allows users to listen to music seamlessly, even on slower internet connections. Therefore, when it comes to online music streaming, MP3 remains the preferred choice for the majority of users.

5. Perceived audio quality and listener preferences

The perception of audio quality is subjective and varies from person to person. Audiophiles and discerning listeners often swear by FLAC’s superior audio quality and the immersive listening experience it offers. However, the difference in sound quality between FLAC and high-bitrate MP3 is not always noticeable to the average listener, especially when using standard earphones or inexpensive headphones.

Listeners with more sophisticated audio equipment or trained ears may appreciate the nuances in FLAC audio, while casual listeners may be content with the convenience of MP3 and the ability to carry thousands of songs in their pockets.

“You don’t need expensive audio gear to enjoy FLAC music, but if you invest in good speakers or headphones, the difference becomes apparent. FLAC is like an art gallery for your ears, presenting music with stunning detail and accuracy.” – Jane Doe, Audiophile Blogger

6. FLAC vs. MP3: The Verdict

In conclusion, the FLAC vs. MP3 debate boils down to personal preferences, use cases, and the level of importance placed on audio quality versus file size and portability. Audiophiles and music enthusiasts seeking the best sound experience and have ample storage should opt for FLAC. On the other hand, casual listeners, frequent travelers, and online music streamers may find MP3 to be more practical and convenient.

Ultimately, both formats have their place in the world of digital audio, and the right choice depends on what you value most in your music listening journey.

Final Words

FLAC and MP3 are two distinct audio formats, each with its strengths and weaknesses. While FLAC offers unparalleled audio fidelity and is ideal for archiving, MP3’s smaller file sizes and widespread compatibility make it the go-to choice for everyday listening and online streaming. Regardless of your choice, both formats serve the purpose of delivering music to our ears and enriching our lives through the power of sound. The key is to find the format that aligns with your preferences and enhances your overall music experience.

Mp3 vs Flac: Which is Better?

MP3 vs. FLAC: Understanding the Difference and Choosing the Best Audio Format

In the world of digital music, two audio formats have dominated the landscape for years: MP3 and FLAC. Each format has its own unique characteristics, advantages, and disadvantages, making it essential for music enthusiasts to understand the differences between them. This article delves into the comparison of MP3 and FLAC, aiming to shed light on which format might be the better choice for different scenarios.

MP3: The Pioneer of Digital Audio Compression

The MP3 format, short for “MPEG Audio Layer III,” revolutionized the way music was consumed and shared since its introduction in the 1990s. Its main advantage lies in its ability to significantly reduce the file size of audio tracks without compromising audio quality too severely. This compression is achieved by discarding some audio information that the human ear may not easily perceive. As a result, MP3 files are much smaller compared to the original CD-quality audio, making them easy to store and share.
However, this level of compression does come at a cost. Audiophiles and music purists argue that the removal of some audio data can result in a loss of sound fidelity, leading to a phenomenon known as “lossy” compression. While the difference in quality might not be noticeable to the average listener, those with a keen ear or listening on high-end audio equipment might discern a slight reduction in audio clarity.

FLAC: Uncompromising Audio Quality for Audiophiles

FLAC, short for “Free Lossless Audio Codec,” is the go-to format for audiophiles and music professionals seeking the highest level of audio quality. Unlike MP3, FLAC uses “lossless” compression, which retains all the original audio data during encoding. This means that no audio information is discarded, resulting in bit-for-bit identical sound quality to the source material, typically CD-quality audio.

The advantage of FLAC lies in its ability to offer pristine audio quality while maintaining a much smaller file size compared to uncompressed audio formats like WAV. This makes it an ideal choice for audiophiles who demand top-notch sound reproduction and a preference for archival purposes. However, due to the lack of audio data removal, FLAC files are considerably larger than MP3s, which can be a drawback for those with limited storage space or slower internet connections.

As J.R.R. Tolkien once said in “The Lord of the Rings,” “Not all those who wander are lost.” Similarly, in the realm of digital audio formats, not all users have the same requirements. Deciding between MP3 and FLAC ultimately depends on your individual needs, preferences, and listening habits. If you prioritize convenience, easy sharing, and reasonable audio quality, MP3 might suit your needs. On the other hand, if you’re an audiophile who values uncompromising sound fidelity and doesn’t mind the larger file sizes, FLAC could be the perfect fit.

In conclusion, the choice between MP3 and FLAC boils down to a trade-off between file size and audio quality. MP3 offers convenience and reasonable audio quality, making it an excellent choice for casual listeners, while FLAC delivers unparalleled sound fidelity for the most discerning ears. Regardless of your choice, both formats have significantly shaped the way we enjoy and consume music in the digital era. So, whether you’re on a road trip, at the gym, or relaxing at home, the right audio format will ensure you have a memorable musical experience.

What is MP3?

MP3 is a type of audio file that is compressed using a specific algorithm to reduce its size while maintaining its sound quality. MP3 stands for MPEG-1 Audio Layer 3 and was developed in the 1990s. Since then, it has become one of the most popular audio file formats in the world.

How does MP3 compression work?

MP3 compression works by removing sounds that are less important to the human ear. This process is called psychoacoustic analysis. The MP3 algorithm uses this analysis to determine which sounds to keep and which ones to discard.

For example, when you listen to music, you may not be able to hear sounds that are below a certain volume level. The MP3 algorithm takes advantage of this fact by removing these quieter sounds from the audio file.

In addition to removing quiet sounds, the MP3 algorithm also removes sounds that are masked by louder sounds. For example, if a loud drumbeat is playing at the same time as a quieter guitar solo, the algorithm will remove the guitar sounds that are masked by the drumbeat.

What are the benefits of using MP3 files?

There are several benefits to using MP3 files. One of the main benefits is that they take up less space than other audio file formats. This makes them easier to store and share.

Another benefit of using MP3 files is that they can be played on a wide variety of devices. Many music players, smartphones, and computers can play MP3 files without the need for additional software.

How are MP3 files encoded?

To create an MP3 file, you need to encode it using an MP3 encoder. The encoder takes the raw audio data and applies the psychoacoustic analysis and compression algorithms to create the final MP3 file.

There are several software programs that can be used to encode MP3 files, including iTunes and Audacity. Many music players also include built-in MP3 encoders.

What are the drawbacks of using MP3 files?

One of the main drawbacks of using MP3 files is that the compression process can result in a loss of sound quality. While the human ear may not be able to hear the sounds that are removed during the compression process, some people may be able to notice a difference in sound quality between an MP3 file and a file that has not been compressed.

Another potential drawback of using MP3 files is that they may not be suitable for all types of music. The psychoacoustic analysis used by the MP3 algorithm is based on the characteristics of typical music. As a result, some types of music, such as classical music, may not be compressed as effectively as other types of music.

What is MP3 Decoding?

MP3 decoding is the process of converting an MP3 file back into a digital audio signal that can be played by speakers or headphones. This process is the reverse of MP3 encoding and involves decompressing the audio data that was removed during the compression process.

To decode an MP3 file, you need to use an MP3 decoder. Many music players and software programs include built-in MP3 decoders that can be used to play MP3 files.

MP4Gain for Converting and Normalizing Audio and Video Formats

If you are looking to convert and normalize various audio and video formats, including MP3, you may want to consider using MP4Gain. MP4Gain is a software program that allows you to adjust the volume and normalize the loudness levels of your audio and video files.

In addition to MP3, MP4Gain supports a variety of other audio and video formats, including MP4, AAC, FLAC, and more. With MP4Gain, you can ensure that your audio and video files are all at a consistent volume level, making it easier to listen to and enjoy your media collection.

Conclusion

MP3 is a popular audio file format that is widely used for storing and sharing music. The MP3 algorithm uses psychoacoustic analysis to compress audio data and remove sounds that are less important to the human ear. While MP3 files have several benefits, they may not be suitable for all types of music, and the compression process can result in a loss of sound quality.

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.

Mp4Gain is the ideal program to normalize and convert both formats because it is the software developed exactly for that purpose for most audio and video formats.

Still using MP3? If you want to listen with real sound quality, maybe you should use “FLAC”.

MP3 vs FLAC

“MP3” is said to be the most popular music file format, but few people know about “FLAC”.

Flac vs Mp3

FLAC is great. If you still use MP3, try this FLAC.

It will surely bring you beautiful sound quality instead of poor sound quality MP3.

Differences in each music file format
music

I will explain the following three typical in advance.

WAV
MP3
FLAC
The general picture is like “compress WAV (original data) and convert it to MP3 or FLAC”. Once you understand the basics, you’ll be able to figure it out with no problem, so let’s take a closer look.

WAV (uncompressed)
wave

This “WAV” is the original music file format.

It is recorded on music CD in this “WAV” format, a file format with the best sound quality.

However, since there is only original data that has not been compressed, the file size is quite large and the duration of one hour is about 600 MB.

Few people listen to this “WAV” format as it is.

MP3 (lossy compression)
mp3

It is a famous “MP3” file format.

This “MP3” is a wonderful format that can compress WAV, which is the original data, and reduce the file size to about 1/10.

Until recently, 2GB and 4GB of memory were common, so it was very useful due to its small file size.

However, due to compression, “sound quality” deteriorates significantly, and audiophiles who are picky about sound will not use “MP3” first.

FLAC (lossless compression)
flac

It is “FLAC” that is gaining popularity in the audio world.

The best thing about this FLAC is that the sound quality is the same as WAV (original data). Also, the file size could be compressed to about a fifth of WAV.

Recently, large-capacity memory such as 64GB has become widespread due to cost reduction, so this “FLAC” begins to be widely used. Even if you think of a song in 5 minutes, you can fit about 2000 songs in 64GB memory.

* By the way, Apple products (iPhone, etc.) do not support FLAC, and the “ALAC (Apple Lossless Audio Codec)” format is mainly used, which is the same as FLAC and does not deteriorate the sound quality.

Which is better, “MP3” or “FLAC”?
music

Advantages of “MP3” over FLAC
Since the size of “MP3” is about half that of FLAC, you can fit a lot even with a small memory capacity.
Most older music players support MP3, so you can use any device.
The advantage of “FLAC” over MP3
Since the sound quality is the same as the original data, you can enjoy cleaner and more vivid sound quality than MP3.
Since it’s “lossless compression”, it’s possible to go back from FLAC to “WAV” (I don’t use it much though).
My personal conclusion is that “FLAC” is better than MP3
music

All the files in my music player are “FLAC”.

As mentioned above, the reason is that high-capacity memory is available cheaply these days, so even FLAC is less likely to fill its capacity.

Amazon’s microSD card is sold at a very reasonable price, with 32GB memory for 1,750 yen and 64GB memory for 3,779 yen. Since the capacity of memory cards is expected to increase in the future, the number of FLAC users will continue to increase.

And finally, there is a point, “highest sound quality”.

It is not possible to clearly distinguish the sound between MP3 and FLAC, but still, the placebo effect (believing effect) is created just by saying “this is the most beautiful sound quality”. It is just that.

Is the difference between FLAC and MP3 reversible?

When enjoying music while commuting to work or school or relaxing at home, many people put their favorite music on their portable music players and smartphones and play it. However, few people seem to have a good understanding of what music is like as data.

Even if it says “put music on a device”, there are actually several types of data formats.

In most cases, compressed audio files are used because the data size is too large to save the audio file as is.

Now let’s talk about the features of FLAC and MP3, which are the most commonly used compressed files.

MP3 is “lossy compression”
MP3 is one of the files compressed by a method called “lossy compression”.

Lossy compression, as its name implies, is a compression method that cannot be restored to the state before compression. In the case of MP3, the data size is obtained by cutting very high and low frequency sounds that are difficult for the human ear. to hear It gets smaller.

MP3s are characterized by huge savings in size and capacity at the cost of slightly deteriorated sound quality.

FLAC is “lossless compression”
FLAC, on the other hand, is one of the files compressed by a method called “lossless compression”.

Files in lossless compression format can be restored to the state before compression during playback, so FLAC can be saved with the same sound quality as the original sound source.

Although the capacity is larger than that of MP3, it is characterized by good sound quality.

MP3 saves space, FLAC emphasizes sound quality!
Even for the same music file, it can be said that MP3 emphasizes saving space and FLAC emphasizes maintaining beautiful sound quality.

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.

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.
