What it does
Media Converter extracts and decodes audio from common media files, then exports a standard WAV (PCM) you can use in DAWs, editors, or other Music Identifier tools.
Conversion runs locally: the browser decodes the file and we write an uncompressed WAV. There is no server-side transcoding. Output is always WAV for maximum compatibility; formats like MP3 or AAC encoding would need a heavy WebAssembly encoder and are not part of this lightweight version.
If you drop a video file, only the audio stream is converted.
Why WAV instead of MP3 or AAC
WAV stores audio as uncompressed PCM samples, so writing one out is a simple, fast operation the browser's native Web Audio API can do on its own. Encoding to MP3 or AAC requires a proper lossy codec, which is a meaningfully heavier piece of software to ship and run entirely client-side. WAV also opens without conversion in every DAW and editor, which makes it a safe universal intermediate format even if it is larger on disk.
Typical reasons to convert
Preparing a clip for the Song Recognizer, feeding a video's soundtrack into another local tool, standardizing mixed-format voice memos before editing, or simply getting a playable file out of a container your media player refuses to open.
How to use it
Choose a media file
Upload MP3, WAV, OGG, FLAC, M4A, or a video container the browser can decode.
Wait for decoding
The file is read and decoded in memory. Large files may take a moment on slower devices.
Download WAV
Export a PCM WAV suitable for editing, analysis, or archiving.
Use with other tools
Feed the WAV into Normalize, Compressor, or Song Recognizer without leaving the site.
Tip: If your source file will not open at all in your editor, converting to WAV here first often fixes container or codec compatibility issues before you do any real editing.
Questions about Media Converter
01Can I export MP3?+
Not in this lightweight build. WAV avoids lossy re-encoding and works everywhere. MP3 would require an extra encoder library.
02What about video?+
If the browser can decode the audio track, it is converted. Video frames are not kept.
03Is quality lost?+
You get PCM from whatever the browser decoded. Starting from a lossy file cannot restore original studio quality.
04Is the file uploaded?+
No. Everything stays in the browser.
05What input formats are supported?+
Anything the browser's built-in decoder can read, which typically covers MP3, WAV, OGG, FLAC, M4A, and the audio tracks of common video containers like MP4.
