Core capabilities
Everything you need before transcription.
Replace repetitive preprocessing steps with one desktop workflow built around long-form recordings and AI transcription.
Audio & Video Input
Process common audio and video formats, with automatic video-to-audio extraction before preprocessing.
Custom Chunk Duration
Choose 5, 15, 30, 45, 60, or 120 minute chunks, or enter a custom duration for your workflow.
Smart Chunking
Create standardized 16 kHz mono PCM WAV chunks with a 10-second overlap to reduce the chance of words being lost at boundaries.
Noise Reduction
Reduce unwanted background noise such as fan, AC, hiss, traffic, and environmental noise to help produce cleaner speech.
Volume Enhancement
Improve the audibility of quiet speakers, distant microphones, and recordings with inconsistent speech levels.
AI-Transcription Ready
Prepare standardized audio chunks for downstream transcription systems such as Whisper and other speech-to-text engines.
Broad media support
