Frequently asked
Is WAV better quality than my AAC file? +
WAV is lossless, uncompressed PCM, so it keeps the audio with no further loss. But your AAC source is lossy. The WAV can't recover detail AAC already threw away, so the original AAC quality is your ceiling.
Why would I convert AAC to WAV? +
WAV stores uncompressed PCM, so an editor reads it without decoding and re-encoding between edits, which avoids generation loss. The tradeoff is a much larger file.
Does my AAC file get uploaded? +
No. Decoding runs entirely in your browser with WebCodecs, so the audio never leaves your device. One heads-up: WAV is uncompressed, so the output is much larger. Long files can get big.
