Audio Trimmer

Cut and trim audio clips with an interactive waveform visualizer. Select start and end timestamps and export clean MP3 or WAV tracks. Typical uses include creating custom smartphone ringtones and notification sounds, trimming unwanted silence or mistakes from voice recordings and podcasts, and extracting specific music samples and sound effects for video editing.

Decodes audio into an AudioBuffer, slices buffer samples between selected timestamps, and encodes the sliced buffer into an MP3/WAV file. Its controls cover visual interactive audio waveform display with zoom controls, millisecond-precision start and end trim markers, fade-in and fade-out transition effects, and real-time audio snippet preview before downloading.

Waveform generation requires initial client-side audio decoding. Processing speed and format support depend on the browser, device memory, and source file. Keep the original material supplied to Audio Trimmer until its trimmed Audio has been checked for the intended use.
