Question 1

Does trimming audio upload the file?

Accepted Answer

No. Trimming is done locally in your browser, and the audio never leaves your device.

Question 2

Will the audio quality decrease after trimming?

Accepted Answer

No. This tool directly copies the audio stream without re-encoding, ensuring completely lossless quality, extremely fast processing, and output in the original format.

Question 3

Are the start and end positions accurate?

Accepted Answer

Sufficiently accurate for the vast majority of audio. Since it uses lossless copying, the cut point aligns to the nearest frame boundary, which may differ from the set time by a few milliseconds, with virtually no audible difference.

Question 4

Can you trim a segment from the middle of the audio?

Accepted Answer

This tool is for keeping the segment between start and end times. To remove a middle segment, you can trim the before and after parts separately, then use 'Audio Merge' to concatenate them.
