Download WAVUse one mono or stereo AAC-LC stream in unprotected ADTS framing, with one raw data block per frame. CRC-protected ADTS, other AAC profiles, M4A and MP4 containers, LATM/LOAS and other framing are not supported. WAV matches the inspected signed 16-bit decoded samples without a new lossy encoding; it cannot restore detail lost in AAC encoding and can be much larger. Use a sample rate of 8–48 kHz.
How to convert AAC to WAV
- Choose your AAC (ADTS) file. The current file and duration limits appear above.
- Choose Inspect AAC (ADTS) to upload the original and check its audio.
- Review and confirm each required choice, then choose Convert to WAV.
- Preview if your browser supports it, or download the .wav file.
Which AAC (ADTS) files can I convert?
This page accepts one mono or stereo AAC-LC stream in an .aac file using unprotected ADTS with one raw data block per frame. CRC-protected ADTS, other AAC profiles, M4A or MP4 containers and LATM/LOAS are not supported.
Will WAV restore the original sound?
No. These inputs already use lossy audio compression. WAV preserves the inspected signed 16-bit decoded samples without a new lossy encoding; it cannot recover detail already lost.
What happens to metadata and sample precision?
Inspected tags and chapters are omitted after your confirmation. If decoding requires a reduction to signed 16-bit samples, review and confirm that separate choice before converting. WAV does not add a new lossy audio encoding.
Can I use the related audio containers here?
Use the M4A or MP4 converters for AAC in those containers; this page is for ADTS .aac files.
What are the file and duration limits?
The converter shows the current file-size and duration limits before upload. Only mono or stereo audio at 8–48 kHz is supported. WAV output can be much larger than the compressed input and must also fit the output limit.
