What is an FLAC file?

FLAC (Free Lossless Audio Codec) is an open-source lossless audio compression format that supports multi-format conversion via FFmpeg. FLAC is widely used for high-fidelity audio storage, providing high-quality sound without any loss of audio data, suitable for music production, recording, and audio editing. FLAC files are typically smaller than uncompressed WAV files but retain all the details of the original audio, ensuring the best audio quality.

How to open and play an FLAC file?

FLAC files can be opened and played using various tools. The most popular choices include [VLC](https://www.videolan.org/), [Foobar2000](https://www.foobar2000.org/), and [Audacity](https://www.audacityteam.org/). These tools support not only FLAC files but also a wide range of other audio formats. Most modern media players also have built-in support for FLAC files. On Windows and macOS systems, you can also use built-in media players to play FLAC files. On Linux systems, the `ffplay` command-line tool (part of FFmpeg) can be used to play FLAC files. Regardless of the tool you choose, the process is straightforward: simply double-click the file or right-click and select 'Open'. If you need to convert a FLAC file to another format, FFmpeg provides powerful command-line tools, such as `ffmpeg -i input.flac output.mp3`.
