How do I convert AAC to WAV?

AAC delivers efficient compression, but audio editors and mastering tools prefer uncompressed WAV for clean, artifact-free editing. Converting to WAV turns your AAC into the raw PCM format those programs expect.

Your WAV is ready Download WAV

Upload your AAC file and choose WAV as the output, then download it. AAC is a compressed lossy format and WAV is uncompressed, so the WAV will be much larger and will not sound better, since decompressing cannot restore detail AAC already discarded. WAV simply gives editing software a raw PCM file to work with.

How it works

1

Upload your AAC file

Select or drag in the AAC audio you want to convert. M4A files using AAC work too.

2

Choose WAV as the output

Set WAV as the target so the audio is decompressed into uncompressed PCM.

3

Download your WAV

Save the WAV, ready for your DAW, editor, or CD burning software.

Frequently asked questions

No. AAC is lossy, so anything removed during its compression cannot be recovered. WAV decompresses the audio into a lossless container but does not add back lost detail.
WAV is uncompressed, so it stores every audio sample as raw data. A WAV is often around ten times the size of the AAC it was made from.
Nearly. M4A is a container that usually holds AAC audio, so both convert to WAV the same way and give you an identical uncompressed result.
Use WAV when editing, mastering, or burning to CD. Audio tools work most reliably with uncompressed PCM and avoid extra compression artifacts while you work.
No. The conversion runs online with no signup and no software to install, and your file is deleted after processing.
