¿Qué es Audio Trimmer?
Trim any audio file to a precise start and end point and export it as WAV or MP3 — entirely in your browser. Set your clip range using interactive sliders, choose your output format, and for MP3 select a bitrate of 128, 192, or 320 kbps. WAV output is instant (pure PCM); MP3 encoding uses the lamejs library and shows a real-time progress bar. Ideal for cutting podcast excerpts, clipping sound bites, removing silence from the start or end of a recording, or shortening a music track for a presentation. Your audio file never leaves your device.

Consejos y buenas prácticas
- 💡Listen to the original audio player first to identify the exact timestamps for your start and end points.
- 💡Use WAV output when the trimmed clip will be edited further in a DAW — it's lossless and avoids generation loss.
- 💡Use MP3 at 128 kbps for voice-only content (podcasts, interviews) and 192–320 kbps for music.
- 💡The estimated file size shown updates in real time as you adjust the range — useful for keeping clips within a target size.
Cómo se compara
Most online audio trimmers (e.g. mp3cut.net, Clideo) upload your file to their servers before processing. TinyTool's audio trimmer runs entirely in your browser, meaning no upload delay, no file size limit imposed by a server, and complete privacy. The trade-off is that MP3 encoding speed depends on your device's CPU.
