Turn M4A recordings and music into uncompressed WAV files for editing, mastering, transcription, or software compatibility. No signup, no software, and local browser processing for files from your device.
Drop a M4A or another supported file here to convert, or import from:
M4A recordings can be inconvenient in older editors, transcription pipelines, samplers, and delivery systems. WAV provides an uncompressed PCM working file with explicit technical settings.
Choose sample rate, bit depth, and channels, or keep compatible source parameters to avoid unnecessary resampling before the next production step.
Upload M4A or another supported source while this workflow keeps WAV as the destination format.
Convert one file or process up to 10 tracks sequentially, then download individual WAV files or a ZIP.
Set sample rate, bit depth, and channels, or retain compatible source parameters.
WAV output does not recover detail removed by AAC compression inside the M4A source. It creates an uncompressed working copy.
Upload one M4A recording or a batch, set the PCM requirements, review the output-size estimate, and create WAV working copies.
Drop one file into the uploader, or choose Batch Convert for up to 10 files. Source formats and technical details are detected automatically.
Choose sample rate, bit depth, and channels, or keep compatible values from each source. Check the estimated output size.
Start sequential browser processing, preview a single result, or save batch files individually or together in a ZIP archive.
Choose this format direction when WAV's compatibility or workflow fit matters more than keeping the original M4A container.
Convert an M4A Voice Memo, interview, or podcast recording into WAV for a DAW or waveform editor.
Use WAV when speech tools, datasets, or production systems request uncompressed PCM audio.
Create a broadly accepted WAV handoff without changing the original M4A file.
These recommendations are specific to M4A sources and WAV delivery rather than generic conversion advice.
Convert Voice Memos and AAC-based recordings when a DAW, transcription tool, or production system expects PCM audio.
Keeping the original sample rate and channel count avoids an unnecessary resampling step before editing.
PCM WAV stores every sample without perceptual compression, so use the output estimate before converting long recordings or batches.
The formats solve different delivery needs. Keep the source when you may need its original quality or metadata, and create WAV as the working or listening copy.
| Format detail | M4A | WAV |
|---|---|---|
| Format type | MPEG-4 audio, usually encoded with AAC | uncompressed PCM audio |
| Typical file size | Small to medium | Large |
| Quality model | Usually lossy AAC | Lossless when created from a lossless source |
| Best used for | Apple devices, mobile playback, podcasts, and compact music files | Editing, DAWs, mastering, transcription, and production handoff |
| Compatibility | Excellent in the Apple ecosystem and modern players | Excellent in editors and desktop software |
WAV is uncompressed, so the converted file will normally be much larger than the M4A source.
Add a M4A file, confirm WAV as the output, select Convert Audio, and download the finished file. The conversion runs in your browser for files chosen from your device.

Files selected from your device are decoded and encoded locally in the browser. Imports from a link, Dropbox, or Google Drive first use the selected provider and configured import service.
Single files are limited to 200 MB. Batch mode accepts up to 10 files or 500 MB total and processes them sequentially to reduce browser memory pressure.
Yes. Switch to Batch Convert, add up to 10 supported files, and download each WAV result separately or together in a ZIP archive.
Yes. WAV remains the output for this focused page, but the uploader accepts every supported audio source and MP4 audio input. Use the main Audio Converter to choose a different output.
Keeping the detected sample rate and channels is the safest default. Choose 48 kHz only when a video or broadcast workflow specifically requires it.
No. WAV stores the decoded signal without another lossy encode, but it cannot restore information removed by AAC compression inside the M4A.
Convert MP3, WAV, M4A, FLAC, OGG, AAC, AIFF, WMA, Opus, and AMR, with optional MP4 audio input and ALAC output.
Convert MP4, MOV, AVI, MKV, WEBM, FLV, or WMV entirely in your browser.
Detect monophonic pitch, clean up timing, transpose notes, preview the result, and export a standard MIDI file.
