About this conversion
What happens
After consent, conversion runs offline, preserves the admitted sample rate and channels, removes metadata, and passes independent RIFF validation.
Limits
250 MiB input. 15 minutes, up to 0×0, and 200 MiB output.
Things to know
WAV is uncompressed and usually much larger than M4A; it cannot restore detail already removed by AAC compression. Video, multiple or unsupported streams, malformed ISO-BMFF, excessive expansion, or invalid WAV output fail closed.
