Sample converter

What it does
- Accepts a folder of files or a single ZIP
- Converts everything to 44.1 kHz · mono · 16-bit WAV (TŒRN’s sample format)
- Runs entirely in the browser (ffmpeg.wasm) — files are not uploaded to a server
- Normalizes awkward characters in folder/file names to ASCII
- SD CARD section: download
SD-CARD-CONTENT.zip— default packs, settings, and folder layout for a fresh microSD
Use with the device
- Convert your samples (or grab the default SD ZIP).
- Copy the result to the card root (or into
samples/as documented on the tool page). - Or push files while the card stays in the unit via the SD tool.

Local run

cd standalone-tools/audio-converter-standalone
python3 -m http.server 8080
# open http://127.0.0.1:8080/
