Frequently Asked Questions
How do I cut out a fragment from the middle of a song?
Go to the "Cut Out" tab and select the area on the waveform you want to remove. The parts of the track before and after will automatically be joined into one audio file.
Can I trim audio with millisecond precision?
Yes! You can manually enter time in the "Start" and "End" fields with precision to thousandths of a second (e.g., 1.234 sec). Our editor provides professional-grade trimming accuracy.
Can I save the trimmed file in a different format?
Yes! After trimming, you can choose any output format — MP3, WAV, FLAC, OGG, and more. The tool automatically converts while trimming, so you get a clean cut in your desired format without a separate conversion step. Need a ringtone? Use the ringtone maker for iPhone and Android.
How do I add a fade out at the end?
Go to the "Fade In/Out" tab and enable Fade Out. Adjust the fade duration with the slider — from 0.5 to 15 seconds. This will make your track ending sound more professional.
What is the maximum file size? Can I process large files?
The maximum file size is 1 GB. Files up to 150 MB are processed quickly on most devices. For larger files (150 MB – 1 GB), processing speed depends on your device's RAM and processor. Modern devices with 4+ GB of RAM typically handle large files without issues. All processing happens locally in your browser.
