Desktop converters require downloads. Online converters upload your files to unknown servers. AudioUtils does neither. It runs WebAssembly in your browser tab.
The conversion is fast. A typical 5-minute audio file converts in under 3 seconds. No progress bars that stall at 99%.
AAC is lossy. Converting to WAV won't restore lost data, but gives you an uncompressed container for editing workflows. Works on Chrome, Firefox, Safari, and Edge. Any device, any OS.
Frequently Asked Questions
Will converting AAC to WAV restore lost quality?
No. AAC is lossy, and the discarded data can't be recovered. The WAV file will have the same audio quality as the AAC source, just in an uncompressed container compatible with more tools.
How much larger will the WAV file be?
Roughly 7-10x larger. A 5MB AAC file becomes about 40-50MB as WAV. Uncompressed audio takes significantly more storage.
What's the difference between AAC and M4A?
AAC is the compression codec. M4A is a common container file that holds AAC audio. Both convert to WAV the same way — this tool handles either.
