WMA to WAV Converter
Inspect your WMA file metadata in the browser and generate the perfect FFmpeg command to convert it to uncompressed WAV — no upload required.
Inspect WMA Metadata
Drop a WMA (or any audio) file to read its properties. Nothing is uploaded.
FFmpeg Command Generator
ffmpeg -i input.wma -c:a pcm_s16le -ar 44100 -map_metadata 0 output.wav
Install FFmpeg free at ffmpeg.org.
Replace input.wma with your actual filename.
Batch convert (Linux / macOS)
for f in *.wma; do ffmpeg -i "$f" -c:a pcm_s16le -ar 44100 -map_metadata 0 "${f%.wma}.wav"; done
Batch convert (Windows PowerShell)
Get-ChildItem *.wma | ForEach-Object { ffmpeg -i $_.FullName -c:a pcm_s16le -ar 44100 -map_metadata 0 ($_.BaseName + ".wav") }
GUI alternatives
- VLC Media Player — free, cross-platform; use Media > Convert/Save, select WAV as output format
- Audacity — free, open-source; import WMA (requires FFmpeg library), then File > Export as WAV
- fre:ac — free, open-source, Windows / macOS / Linux, supports WMA input and WAV output
- dBpoweramp — paid, Windows / macOS, batch WMA-to-WAV with DSP processing options

WAV Bit Depth Reference
| Codec Flag | Bit Depth | Size / min (stereo) | Best For |
|---|---|---|---|
| pcm_s16le | 16-bit | ~10 MB | CD, playback, general use |
| pcm_s24le | 24-bit | ~15 MB | Professional recording, DAW |
| pcm_f32le | 32-bit float | ~20 MB | Mixing, DSP, avoid clipping |
Sizes assume 44,100 Hz stereo. WAV files are uncompressed — always larger than the WMA source.
WMA vs. WAV — At a Glance
WMA (Windows Media Audio)
- Small file size — good compression at low bitrates
- WMA Lossless variant preserves every audio sample
- Proprietary Microsoft format — poor cross-platform support
- Not accepted by most DAWs without a plugin or FFmpeg bridge
WAV (Waveform Audio File Format)
- Uncompressed PCM — zero quality loss during editing
- Universally supported by every DAW, video editor, and OS
- Ideal for professional workflows, mastering, and archival
- Large file sizes — 10–20x larger than equivalent WMA
- No metadata container standard — tags may be stripped by some players
Summary
Inspect your WMA file metadata in the browser and generate the perfect FFmpeg command to convert it to uncompressed WAV — no upload required.
How it works
- Drop a WMA file onto the inspector panel (or click to browse).
- The Web Audio API reads the file's sample rate, duration, and channel count locally.
- Choose a WAV bit depth — 16-bit for CD quality, 24-bit for professional audio, 32-bit float for editing.
- Copy the generated FFmpeg command and run it in your terminal.
- Verify the output WAV in a player or DAW before deleting your original WMA.
Use cases
- Convert a WMA recording to WAV for editing in Audacity, Adobe Audition, or any DAW.
- Prepare WMA files for import into video editors such as DaVinci Resolve or Premiere Pro.
- Archive WMA music as uncompressed WAV to preserve audio quality without re-encoding.
- Convert WMA speech recordings to WAV for transcription services or voice recognition tools.
- Batch-convert an entire WMA library by adapting the single-file command into a shell loop.
- Check a WMA file's sample rate and channel count before deciding on a conversion target.
- Estimate the WAV output file size before committing to a bit depth.
- Generate a ready-to-paste FFmpeg command without memorizing its flags.
