よくある質問
Quick answers.
›Which audio formats are supported?
You can trim standard audio formats including MP3, WAV, OGG, and AAC. Support depends on your browser's native capabilities.
›Is my audio file uploaded to a server?
No. All processing happens locally on your device via your browser. Your files never leave your machine.
›How precise is the trimming?
The tool provides millisecond precision. Use the waveform visualiser to find exact transients or silent gaps for clean cuts.
›Can I fade in or fade out?
This specific tool is designed for simple cutting and trimming. For complex effects like crossfades or multi-track editing, a dedicated digital audio workstation is required.
