How to Convert WAV to MP3 (or Other Formats)
When to convert WAV to MP3, when not to, and the file-size trade-offs. Browser-side metadata inspection for audio without needing server-side encoding.
Tool vs conversion
Audio Extractor inspects metadata (duration, bitrate, sample rate, channels). For actual WAV → MP3 encoding:
- ffmpeg (desktop, command line)
- VLC (GUI)
The WAV vs MP3 trade-off
WAV: uncompressed, ~10 MB/minute, CD quality. MP3: lossy compressed, ~1 MB/minute, requires a quality level.
Is it worth converting?
When storage matters more than the audible difference, yes. Otherwise no.
Note
MP3 encoding requires LAME or a similar codec; in-browser implementations are heavy (>100 KB JS) and we don’t ship one at the moment.
