Drop Straight into Your DAW
WAV is the native import format for Pro Tools, Logic Pro, Ableton Live, FL Studio, and every other major DAW. Converting your AAC file first removes any re-encoding step and keeps your project chain clean.

No Compression Artifacts in Your Mix
AAC uses lossy compression that can introduce subtle smearing and pre-echo artifacts. Working from a decoded WAV file means those artifacts do not compound when you export your final mix or bounce stems.

Deep Dive
AAC vs WAV: What Changes When You Convert
AAC compresses audio by discarding data the ear is unlikely to notice. WAV stores every decoded sample without any compression. Here is what that difference means for your workflow.
Output sample rate and bit depth match the decoded AAC stream. No upsampling or bit-depth padding is applied.

Frequently Asked Questions
Does converting AAC to WAV improve audio quality?
No. AAC is a lossy format and any audio data discarded during the original encoding is gone permanently. Converting to WAV decodes the existing audio into an uncompressed container, which prevents any further quality loss in subsequent editing or re-exporting.
Why is the WAV file so much larger than the AAC?
WAV stores every decoded audio sample without compression. A one-minute 128 kbps AAC file is roughly 1 MB; the same audio as a 16-bit 44.1 kHz WAV is about 10 MB. The larger size reflects the full uncompressed waveform, not a quality improvement.
What sample rate and bit depth will the output WAV use?
The output sample rate and bit depth match what the AAC decoder produces from your source file. No upsampling or bit-depth padding is applied. A typical AAC decoded from an iTunes or streaming source will produce 44.1 kHz or 48 kHz 16-bit PCM.
Will the converted WAV work in my DAW?
Yes. WAV with PCM encoding is the native import format for every major DAW including Pro Tools, Logic Pro, Ableton Live, FL Studio, Cubase, and Reaper. No additional codec or driver is needed.
Is there a file size limit?
The upload limit is 100 MB per file. Most AAC tracks and albums are well within this limit.
Can I convert M4A files containing AAC audio?
Yes. M4A is simply an MPEG-4 container that typically holds AAC audio. Upload your .m4a file the same way you would an .aac file and the converter will decode the AAC stream and output a WAV.
