About WAV and FLAC
WAV .wav
Raw uncompressed audio samples in a thin container. Exactly what came off the recorder, at roughly 10 MB per minute of stereo CD-quality sound.
Good for
- Bit-for-bit perfect — nothing is discarded
- No decoding overhead, so editors handle it fastest
- The standard working format for recording and editing
Trade-offs
- Very large — around 10 MB per minute
- No built-in tags for artist or album
- Impractical for distribution or streaming
audio/wav
FLAC .flac
Lossless compression for audio. Roughly half the size of WAV, and it decodes back to the original samples exactly — nothing is approximated.
Good for
- Perfect reconstruction — identical to the source
- Around 50–60% of the size of WAV
- Full tagging, and an open royalty-free format
Trade-offs
- Still far larger than MP3 or AAC
- Not supported by every portable player or car stereo

What changes when you convert WAV to FLAC
This is a re-encode, not a repackage
Some tools can move a stream into a different container untouched when the codecs happen to line up. We do not — every job here is decoded and encoded again, so the conversion takes time in proportion to the length of the file and costs a small amount of quality even where a repackage would have been possible. In exchange the output is predictable: it plays everywhere, rather than inheriting whatever the source happened to contain.
What your FLAC will contain
The output is FLAC — which is lossless, so there is no bitrate to set — the size is decided entirely by how compressible your audio turns out to be, usually landing near half of the equivalent WAV while preserving every sample exactly.
Nothing is lost in this step
WAV and FLAC both store every sample exactly, so this changes the container and the file size rather than the audio itself. Convert freely and as often as you like — the waveform that comes out is the waveform that went in.
Tags may not survive intact
WAV stores its metadata as RIFF INFO chunks, which many players ignore entirely, and FLAC uses Vorbis comments. Standard fields such as title, artist and album normally map across. Anything without an equivalent on the other side — unusual custom fields, some ratings and play counts, occasionally embedded artwork — has nowhere to go. Check the tags before deleting the original if your library depends on them.
