How to Convert AAC to WAV

AAC is a lossy compressed format — efficient for streaming but awkward for editing. WAV is uncompressed PCM — the universal exchange format for audio editing software. Converting AAC to WAV decodes the AAC bitstream into uncompressed samples that any DAW or editor can read directly.

Step-by-step instructions

  1. 1

    Upload your AAC file

    Select your .aac file. The converter decodes the AAC bitstream into 16-bit or 24-bit PCM at the source sample rate (typically 44.1 or 48 kHz).

    Go to converter
  2. 2

    Choose WAV as output

    Select WAV. Choose 16-bit for compatibility (CD-quality, lower file size) or 24-bit for headroom in editing (higher file size, room for processing without clipping).

  3. 3

    Download and import to your DAW

    Open the WAV in Audacity, Logic Pro, Pro Tools, Reaper, or any DAW. WAV requires no codec — it loads instantly with full editing capability.

Why convert AAC to WAV?

Frequently asked questions

Will AAC to WAV recover lost quality?
No. AAC is lossy — information was permanently discarded during the original AAC encoding. Converting to WAV creates an uncompressed file from the lossy AAC, but the discarded information cannot be recovered. WAV will sound exactly like the AAC, just larger.
FFmpeg command for AAC to WAV?
`ffmpeg -i input.aac -c:a pcm_s16le output.wav` for 16-bit. For 24-bit: `-c:a pcm_s24le`. For 32-bit float: `-c:a pcm_f32le`.
How much larger will the WAV be vs the AAC?
AAC at 256 kbps is about 1/10 the size of 16-bit WAV. A 5 MB AAC will become roughly 50 MB as 16-bit WAV at the same sample rate. 24-bit WAV will be 50% larger again.
