常见问题
Why is there a file length recommendation?
Audio reverse loads the entire file into memory before reversing. Short clips (under 5 minutes) work best. Longer files may cause memory issues in the browser.
Does reversing audio change the pitch?
Yes, reversed audio naturally plays at the same speed but with all frequencies reversed in time. It creates the characteristic 'backwards' sound.
Can I reverse a portion of the audio?
Use the Audio Trimmer first to cut the section you want, then reverse the trimmed clip.
