SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Noisy recordings with ambient sound, background music, or echo degrade podcasts, interviews, and voiceovers, and manual audio cleanup requires specialized editing tools and expertise.

Core Features & Use Cases

  • Noise Removal: Strips ambient noise, background music, reverb, wind, traffic, and electrical hum from audio recordings.
  • Vocal Isolation: Extracts clean voice tracks from mixed audio, supporting WAV, MP3, FLAC, OGG, and AAC up to 500MB and 1 hour.
  • Pipeline Integration: Chains with transcription, voice changing, and video merging workflows through the belt CLI.
  • Use Case: A podcaster records an interview in a café; run the voice isolator to remove background chatter, then transcribe the cleaned audio with speaker diarization.

Quick Start

Files are limited to 500MB and one hour, and the tool targets non-voice sounds like noise, music, and reverb. Overlapping speakers or extremely degraded sources may still retain artifacts after processing.
