Set it once. Finish the whole folder.
Build the workflow you need
Trim silence, cut start or end, match perceived loudness with Streaming, Podcast or Broadcast presets, peak-normalize and fade. Reorder the steps and Batch remembers the setup next time.
Your originals stay untouched
Every result goes to a folder you choose. Existing files are never overwritten, and cancelled or failed work leaves no partial export behind.
Choose the result
Export WAV or AIFF at up to 96 kHz with 16, 24 or 32-bit PCM, or make a compact high-quality M4A at up to 48 kHz. Preserve source metadata when you need it, or remove it for a clean export.
