Upload folder files or one ZIP. Output is always 44.1 kHz / mono / WAV.
Your files stay on your device. Conversion runs entirely in your browser; nothing is uploaded to this server. Special characters in folder/file names are normalized to ASCII. Unsupported characters are replaced with “-”.
SD CARD
Download the default TŒRN SD card content — sample packs, settings, and folder layout. Extract the ZIP and copy the contents to your microSD card.
Download SD-CARD-CONTENT.zipRecommended card
- SanDisk Ultra microSD (grey label)
- Speed class: UHS-I (Class 10)
- Capacity: up to 64 GB
- Use a genuine card from a trusted retailer — counterfeits often cause read errors or missing samples.
How to format
- Insert the microSD card into your computer with a card reader (not the TŒRN unit).
- Download and run the SD Memory Card Formatter from the SD Association.
- Select your card, leave Format type on Quick format, and click Format. Cards up to 32 GB are formatted as FAT32; 64 GB cards use exFAT — both work with TŒRN.
- Extract SD-CARD-CONTENT.zip and copy all files and folders to the root of the card (not inside a subfolder).
- Eject the card safely, insert it into TŒRN, and power on.
Avoid formatting through Windows Explorer or macOS Disk Utility if possible — the SD Association tool sets the correct partition layout for removable media.
