What is FLAC, and How to Use the Lossless Audio Format

What is FLAC, and How to Use the Lossless Audio Format

Music is a universal form of art and entertainment that people across generations love and consume. Because of its limitless diversity and timelessness, the consumption of music has continuously evolved through time. From antique vinyl records to the development of radio, portable disc players, digital music players, and music streaming platforms, the way people listen to music will only continue to evolve over time.

In modern times, digital audio has become the primary source of music for everyone since smartphones have evolved to become a necessity in today’s society. However, digital audio formats are as diverse as the countless genres of music that people listen to worldwide; because of that, several formats are not that familiar to everyone, and one of them is the FLAC audio format. In this article we will discover everything we need to learn about FLAC files to discover how to listen to them, what are FLACs, what are the best tools to play them, and how does it compare to the closely related ALAC audio files.

What Is FLAC

Part 1. What is FLAC File

For meticulous audiophiles who consider seamless audio listening as a part of their day-to-day lives, learning what is the best audio format for their favorite hobby is vital. With that in mind, FLAC or Free Lossless Audio Codec files will be the best format for them. As mentioned in the name itself, FLAC audio is saved with all of its audio codec intact, making its quality as high and as retained as possible, but it is compressed with more than half of its original file size.

In fact, it is often used by a niche community of music lovers, such as passionate music enthusiasts drawn to high-quality music since it’s almost a perfect copy of the original recording. Because of this, digital audio saved in FLAC format will be able to retain its original quality. With FLAC, high quality music files will retain their original quality but are compressed at half its original size.

However, its extremely high audio quality comes at a bigger price since, despite its lossless compression, its file size is about three to four times larger than regular MP3 audio. As an example, a four-minute song saved in MP3 format only clocks in at about nine megabytes; meanwhile, the same music saved in FLAC format is a whopping 28 megabytes in size.

FLAC MP3 File Size Comparison

When it comes to typical music listening sessions on a slow Sunday morning, digital audio saved on MP3 is more than enough since most sound systems and entry-level earphones and headphones won’t be able to pinpoint their differences. However, professional music producers, singers, and dedicated audiophiles are most likely equipped with advanced music tools to help them produce and listen to music at the highest level; this scenario is where FLAC audio will take its place.

To learn how to play FLAC files, please proceed to the next part of this article, where we will recommend the best tool you can use to listen to music of the highest quality possible.

Part 2. How to Play FLAC Files

Since FLAC files are still a digital audio format at its core, most media players will have no problem playing it since advanced digital music files are not as intricate as videos, whereas some formats require advanced media players. However, these basic music players won’t be able to bring the full experience that the lossless quality of FLAC audio provides to the table. With that, using an advanced multimedia player is the optimal way of listening to it, and the best program available today is none other than AnyMP4 Blu-ray Player.
