Converting a lossy AAC file to WAV doesn't restore any detail AAC's compression already discarded, that damage was done during the original encoding and no format change afterward gets it back, what actually happens is the compressed audio gets decoded into an uncompressed, universally readable container instead. This tool converts AAC into WAV, producing a file virtually any audio editor or piece of hardware can open without needing an AAC decoder installed at all.

Quick answers for AAC to WAV Converter

How does the AAC to WAV conversion work?
The tool decodes your AAC audio with the browser's Web Audio API, then writes the decoded samples into a standard 16-bit PCM WAV file at the same sample rate and channel count as the source.
Is the WAV output lossless?
The step from decoded audio to 16-bit PCM WAV adds no further compression, so you get the full decoded signal. Quality lost during the original AAC encoding can't be recovered at this stage, since AAC is a lossy format.
Does it handle stereo audio correctly?
Yes. The tool reads the channel count from the decoded audio buffer and writes each channel into the WAV file, so mono and stereo sources both convert correctly.
