โ Frequently Asked Questions โ Audio Trimmer
What audio formats can I trim?
You can load any audio format your browser supports for playback โ typically MP3, WAV, OGG, FLAC, AAC, and M4A. The trimmed output is saved as WAV (lossless), which is compatible with all music players and editing software.
How precise is the trimming?
The trimming uses the Web Audio API which works at the sample level, allowing precision up to milliseconds. You can enter decimal values like 12.345 for 12 seconds and 345 milliseconds. For most practical purposes, the precision is more than sufficient for cutting music, podcasts, or voice recordings.
Is my audio file uploaded to a server?
No โ your audio file never leaves your device. All processing happens entirely in your browser using the Web Audio API. This makes the tool 100% private, and it works even without an internet connection once the page is loaded.
Can I trim multiple sections from one file?
Currently the tool trims a single continuous segment (start to end time). To extract multiple sections, trim and download each section separately by adjusting the start/end times for each desired segment. For complex multi-cut editing, a desktop app like Audacity (free) would be more efficient.
