FLAC (Free Lossless Audio Codec) is a compressed audio format that preserves the original audio quality without loss of data.
Response to your inquiry in detail
FLAC (Free Lossless Audio Codec) is indeed a compressed audio format but, unlike lossy formats such as MP3, it retains the original audio quality without any loss of data. This makes it a popular choice among audiophiles and music enthusiasts who value high-fidelity sound reproduction. To understand FLAC in more depth, let’s dive into some interesting facts about this audio codec:
-
Lossless Compression: FLAC achieves compression by eliminating redundant information, making the file size smaller without sacrificing audio quality. It employs a lossless compression algorithm, meaning that the exact original signal can be reconstructed from the compressed file.
-
Preservation of Audio Data: Unlike lossy formats that discard certain audio details, FLAC preserves the entire audio data during compression. It accomplishes this by compressing the data without any loss or alteration, resulting in bit-perfect reproduction of the original audio.
-
Bitrate and Size: The compression ratio of FLAC can vary depending on the complexity of the audio being compressed. On average, it achieves a compression ratio of about 50-60%, which means a 50MB WAV file would be reduced to roughly 25MB-30MB in FLAC format.
-
Universal Compatibility: FLAC is a widely supported format across different platforms and devices. Many media players, both software and hardware, can handle FLAC files, making it convenient for playback and storage. Additionally, FLAC supports metadata tagging, allowing users to organize and categorize their music collections effectively.

Quote: “FLAC is a legal lossless internet audio codec developed by the Xiph.Org Foundation. It is a free and open-source codec that ensures the best audio quality while maintaining smaller file sizes than other lossless formats.” – Xiph.Org Foundation
To provide a clearer picture, here’s a table comparing FLAC with other popular audio formats:
| FLAC | MP3 | AAC | |
|---|---|---|---|
| Compression | Lossless | Lossy | Lossy |
| Audio Quality | Uncompressed | Loss of quality | Loss of quality |
| File Size | Larger | Smaller | Smaller |
| Supported Platforms | Wide support | Wide support | Wide support |
| Metadata Tagging | Yes | Limited | Limited |
In conclusion, FLAC stands out as a compressed audio format that offers exceptional audio quality while still maintaining smaller file sizes. Its lossless nature ensures that the original audio data is preserved, making it a fantastic choice for those who value high-fidelity music reproduction.
Response video to “Is FLAC compressed or uncompressed?”
In this video, Paul discusses the comparison between uncompressed and compressed audio files. While he acknowledges that uncompressed files have advantages such as lower strain on power supply and less noise generation, Paul emphasizes that streaming companies prefer compressed files for data usage and cost savings. For local storage, he recommends using uncompressed files like AIFF, which supports metadata. Furthermore, Paul mentions their upcoming server that uses galvanic isolation to completely isolate the digital signal from power supply noise, resulting in improved sound quality. Ultimately, he concludes that there is generally no need for uncompressed audio files unless streaming is a concern, as streaming will always be a part of the audio experience.

FLAC stands for Free Lossless Audio Codec, an audio format similar to MP3, but lossless, meaning that audio is compressed in FLAC without any loss in quality.
When FLAC files are compressed, there is no loss of quality because FLAC will always decode into the exact uncompressed audio track down to every single bit. The only difference between the compression levels is the resulting file size. With other compression methods, such as MP3, various aspects of the files are stripped out to save space.
FLAC is short for Free Lossless Audio Codec which means there is no loss of quality. It is a popular open-source lossless compression file format that offers CD-quality audio sound at half the size. FLAC offers varying levels of lossless compression from 1 through to 8. What are these compression levels?
FLAC files can also provide a resolution of up to 32-bit, 96kHz, so better than CD quality. Other lossless audio file formats include ALAC (Apple Lossless) and WMA Lossless (Windows Media Audio). The former is a good iOS and Apple Music-compatible alternative to FLAC, although the files are slightly less compact than FLACs.
While ZIP may reduce the size of a CD-quality audio file by 10–20%, FLAC is able to reduce the size of audio data by 40–50% by taking advantage of the characteristics of audio. The technical strengths of FLAC compared to other lossless formats lie in its ability to be streamed and decoded quickly, independent of compression level.
Unlike WAV files, FLAC files are compressed. FLAC files take advantage of the fact that an audio file can be compressed to 70 percent of its original size and remain identical to the original file. Compressed files are easier to share. File-sharing websites use FLAC files because compressed files can be downloaded for free.
By being uncompressed, WAV loses nothing in quality but occupies more space on your device, while FLAC is compressed and may lose certain details of the file during compression. However, you won’t notice any bump in quality since FLAC is lossless.
