# How it Works

Split your audio files into meaningful segments with ease. On supported devices, optional local browser-based Whisper word detection can make speech and AI voiceover cuts easier.

#### Lightning Fast

Browser-based processing with Web Audio API

#### Auto-Detection

Smart silence-based segment detection

#### Save Hours

Process 60+ minute recordings in minutes

#### Word Detection

Optional local Whisper AI for supported speech files

## Simple 4-Step Process

1

### Upload Your Audio

Drag and drop any audio file (MP3, M4A, WAV) or click to browse. We support all major audio formats.

### Create Segments

Use auto-detection for long files (8+ minutes), manually select segments on the waveform, or use optional word detection for supported speech files. When you trim a segment boundary, AudioMultiCut instantly previews the first or last second so you hear the change right away.

Manual Selection:

Instant Boundary Preview

As you adjust a segment's start or end inside its card, the app auto-plays the first or last second so you can trim by ear instead of guessing.

Optional Speech Word Detection

On supported computers and browsers, AudioMultiCut can run a small browser-based Whisper AI model to find spoken words and rough word timings. It can miss words and may not be available on every device, but it makes voiceovers, lectures, podcasts, and interviews easier to cut by what is said.

## Powerful Features

Instant Boundary Preview

#### Trim by ear, not guesswork

End trims replay the tail so you can hear clean cutoffs.

What the app is doing

As soon as the new start lands, AudioMultiCut auditions the first second so you can hear the new attack immediately.

Works with both the precision sliders and the mini-arrow buttons inside every segment card.

### Speech Word Detection

For speech files, supported devices can optionally run a local browser-based Whisper AI model to find spoken words and approximate word timings. The words can make it easier to create cuts from a transcript, preview what is under the mouse on the waveform, and see which words fall inside each segment.

Availability varies

This is cutting-edge browser AI. It needs a capable device and compatible browser, may take time to prepare, can miss words, and may not work on every operating system or browser version.

### Auto-Detection (Beta)

For audio files longer than 8 minutes, our smart algorithm analyzes silence patterns to automatically detect natural segment boundaries. You can pick a preset for rehearsals, lectures, podcasts, lessons, or live sets, then tune how much silence stays inside one part versus how long a pause should be before a new part starts.

#### Before Auto-Detection:

🎯 Auto-Cut Detection

#### After Auto-Detection:

**Pro Tip:**The fast auto-cut mode runs a quick envelope scan (<1s) and adapts thresholds to each file without manual tuning, while still enforcing a sensible time-based cap on the total number of detected parts.
