What is a .FLAC file?
FLAC is a popular lossless audio format that compresses without losing any quality.
- Did you know
- FLAC was released in 2001 and is the most popular format for lossless music archiving.
- FLAC compresses audio without discarding a single sample, so a decoded file is mathematically identical to the original recording.
- Development was begun by Josh Coalson and the format now lives under the non-profit Xiph.Org Foundation, the same group behind Vorbis and Opus.
- On the web a .FLAC file is served with the MIME type
audio/flac. - Analyser spots a .FLAC file by its signature bytes
66 4C 61 43- ASCII for "fLaC".
- What Analyser shows you
- Inspect the waveform, spectrogram, codec, bitrate, channels, and tags of MP3, WAV, FLAC, M4A, AAC, OGG, and Opus audio, and play Apple Core Audio (CAF) files such as iMessage voice messages, decoded on-device with FFmpeg where the browser cannot.
- Open a .FLAC file
- Drag a .FLAC file onto the Analyser home page (or tap to pick one). It opens entirely in your browser - nothing is uploaded, there is no account, and it works offline once installed.
