Frequently Asked Questions

This tool supports all common audio formats including MP3, WAV, OGG, FLAC, AAC (M4A), and more. FFmpeg handles format detection automatically, so most audio files will work regardless of extension.

For lossless formats (WAV, FLAC), trimming preserves perfect quality. For lossy formats (MP3, AAC, OGG), we re-encode at high quality settings. To minimize quality loss on MP3 files, the output uses 320kbps encoding.

Click on the waveform to set the playhead position, then use the Start and End time inputs to set exact timestamps. You can type precise values like '1:23.5' for minute:second.millisecond accuracy. Preview your selection before exporting.

Currently, this tool extracts one continuous segment per operation. For multiple cuts, trim each section separately. For more complex editing like removing middle sections, use dedicated audio editing software.

Basic metadata (title, artist, album) is preserved when possible. However, some metadata may be lost during re-encoding. For critical metadata preservation, consider using a dedicated audio editor.

Processing happens in your browser, so limits depend on your device's memory. Most devices handle files up to 100MB or 30 minutes comfortably. Larger files may work but could be slower.

Yes! Use the Preview button to hear the selected portion before exporting. This helps ensure you've selected exactly the right segment without wasting time on full conversions.

The output matches your input format by default. MP3 in = MP3 out, WAV in = WAV out. This maintains format consistency and avoids unnecessary transcoding.

Trimming is accurate to the millisecond. FFmpeg precisely cuts at the specified timestamps. For frame-perfect cuts in lossless formats, the precision is sample-accurate.

No. All processing happens entirely in your browser using FFmpeg WebAssembly. Your audio files never leave your device, ensuring complete privacy.
