About WAV Compressor
WAV is uncompressed, so its size is set by three things: sample rate, bit depth and number of channels. CD-quality stereo uses about 10 MB per minute. If a system requires WAV, you can still shrink it a lot: 22.05 kHz mono at 16-bit is about 2.6 MB per minute, roughly a quarter of the size, and still clear for speech. This tool resamples and re-writes WAV files with the settings you choose. If the file doesn't have to stay WAV, converting to MP3 will make it far smaller still.

Questions
Which settings are best for voice recordings?
16 kHz or 22.05 kHz, mono, 16-bit. Speech stays clear and the file is a small fraction of CD-quality stereo.
Should I use 8-bit?
Only if size matters more than quality. 8-bit halves the size again but adds audible hiss, especially in quiet passages.
Why not just convert to MP3?
MP3 is much smaller, and the WAV to MP3 converter does that. Use this tool when software, a phone system or a device specifically requires WAV files.
Is the audio uploaded?
No. Decoding, resampling and writing the new WAV all happen in your browser.
