Frequently Asked Questions
Everything you need to know about lossless frequency conversion, science, and privacy.
Are my songs uploaded to a server?
No. All audio decoding and pitch-shifting executes directly inside your browser using WebAssembly. Your files never leave your device.
What export format is produced?
Free and PRO exports default to 24-bit 48kHz WAV files, the worldwide standard for video editing, DAWs, and pristine audio playback. PRO users can also choose 32-bit Float 96kHz or 16-bit 44.1kHz.
Can I preview my song before converting?
Yes. Once you select or drop a file, the "Experience the Shift" player loads your track and allows you to toggle live between standard 440Hz and any Solfeggio frequency in real-time.
