- Click New Project in the sidebar (or the "Create Project" button on your Dashboard).
- Choose your upload mode: - Single Track: One before/after comparison (optionally with a third audio file for A/B/C). - Playlist Mode: Multiple tracks in a single player, each with their own before/after files.
- Upload your audio files. Free plans accept lossy formats only (MP3, AAC, OGG, Opus, M4A, WebM). Pro and Studio plans also accept lossless formats (WAV, FLAC, AIFF, ALAC). Maximum file size: 500 MB per file.
- Click "Upload & Create Project" to create your project.
- You'll be redirected to the Edit Project page where you can set the title, artist, genre, description, customize the player appearance, and more.
Tip: Keep your before and after files time-aligned so the toggle switch is seamless. Listeners should hear the exact same moment in the track when they switch.
