Frequently Asked Questions
What audio formats can I cut?
Any format your device can decode — MP3, WAV, FLAC, OGG, M4A, and more. The tool uses the Web Audio API's built-in decoder, so format support matches your device's native capabilities.
How precise is the trim?
Sample-accurate. Drag the left and right handles on the waveform to set your start and end points. The minimum selection is 0.1 seconds. Timestamps display in minutes:seconds.milliseconds format for precise editing.
Is there a duration limit?
Up to 30 minutes of audio. The waveform renders as a peak-amplitude display showing the full timeline, with each pixel representing the min/max sample values for that time slice.
What format is the export?
Multiple export formats are available via the format selector. The trimmed clip preserves the original sample rate and all audio channels from your source file.
Can I use the trimmed clip in other TuneLab tools?
Yes. The trimmed audio automatically saves to your device's local storage. Other tools like BPM Finder or the format converter can pick it up directly — no need to re-upload.
Is my audio uploaded to a server?
No. All trimming and waveform rendering happens entirely on your device. The audio file never leaves your machine.
