About WAV (Waveform Audio)
WAV is audio with nothing hidden and nothing removed: raw PCM samples in a container Microsoft and IBM defined in 1991, unchanged in spirit since. Every digital audio workstation, editor, sampler, transcription tool, and broadcast system reads it, because there is almost nothing to read — no compression to decode, no codec politics, just numbers describing a waveform.
That purity has a price measured in megabytes: about ten per minute of stereo. WAV is the format for making and editing audio, not for moving or storing it — which is why the classic workflow is record and edit in WAV, then publish in MP3. Both directions of that workflow live here, plus a third: extracting WAV straight out of a video when its audio track is headed for production work.
One honest note this site repeats wherever relevant: converting a lossy file to WAV does not restore quality that compression already discarded. It buys compatibility and edit-safety — real benefits — but no tool can un-discard data.
Strengths
- Bit-perfect, uncompressed audio — the reference everything else is judged against
- Universal support in DAWs, editors, samplers, and analysis tools
- Survives unlimited editing and re-saving with zero generational loss
- Conversion here needs no special browser support — it works everywhere
Limitations
- Huge: roughly 10 MB per minute of stereo — painful to email or stream
- No efficiency benefit over lossless-compressed FLAC at half the size
- Converting lossy sources to WAV inflates size without restoring quality
- Minimal metadata support compared to modern formats
