Overview
Audio Splitter is a PySide6 desktop application for splitting audio files at user-defined points. Load an MP3 or WAV file and the full waveform renders immediately. Drag split markers freely to define exact cut positions — no snapping, full manual control.
Transcription runs automatically in the background using a local faster-whisper model the moment a file is loaded. No API key, no internet required after the initial model download. The transcript is saved as a .txt file alongside the audio.
Splitting uses ffmpeg stream copy — no re-encoding — so splits are instant and bit-perfect. Output always matches the input format. The linked chunks/duration controls let you set how many pieces you want or how long each should be, and markers redistribute automatically.
