Frequently Asked Questions
What is the difference between Trim and Cut?
Trim preserves only the selected region and removes everything else. Cut removes the selected region and joins the remaining audio together.
Will trimming lower the audio quality of my MP3?
No. OnlineAudioEdit renders high-bitrate audio buffers ensuring your export sounds as crisp as the original.
