AAC to WAV Converter

How it works

1. Choose your AAC file, or drop it on the page. You can add several files at once.
2. Pick the sample rate and bit depth, or keep the source values to avoid any change.
3. Click Convert. Processing happens on your device and shows progress; you can cancel at any time.
4. Preview the result and download the WAV file. With several files, download them all as one ZIP.

About AAC to WAV conversion

AAC (Advanced Audio Coding, raw ADTS stream) suits streaming-style files and hardware that expects a plain AAC stream. WAV (Waveform Audio File Format, RIFF container) suits editing, mastering, sampling and handing audio between programs without quality loss.

AAC is lossy, and no converter can restore detail that was already discarded. The WAV file will sound the same as the AAC source and will be larger; the point of the conversion is compatibility with software or hardware that needs WAV.

For a 4-minute track, a typical AAC file is about 5 MB and a typical WAV file is about 42 MB. Your own result depends on the bitrate and the audio itself.

AAC vs WAV

WAV support: Opens in every audio editor and operating system. Browsers and phones play it, though not every player shows tags.

AAC support: The codec is everywhere. A bare .aac stream is less common than M4A and often lacks duration and tag information.

Quality and compatibility notes

• WAV: Large files: about 10 MB per minute at CD quality. The classic format stops at 4 GB, which RF64 extends.
• AAC: A bare ADTS stream has no real tag container, so title, artist and cover art are usually missing.
• Tags: WAV stores limited: RIFF INFO chunks, and BWF or iXML metadata in broadcast files.
