## How it works

This tool allows you to trim audio files quickly and easily without uploading them to a server.

Drag an audio file into the box or select it. Once loaded, the waveform is displayed. Use the sliders to set the start and end points. You can preview the selected area and export it in various formats and qualities.

Loads audio files into memory and renders the waveform on a canvas. Trims the selected time region and exports it as a new WAV or MP3 file.
