Overview

The Audio Punch In/Out tool allows you to replace a specific segment of an audio file with another clip. Upload your base audio, define the segment to replace using start time and duration, and provide a replacement clip to generate a new edited file.

  • •When updating specific parts of audio content, such as podcast segments or training materials.
  • •When inserting new audio clips at precise timestamps in existing files for customization.

How It Works

  • •Upload the base audio file that contains the segment you wish to replace.
  • •Enter the start time and duration of the segment in hh:mm:ss[.ms] format.
  • •Upload the replacement audio clip to be inserted at the specified segment.
  • •Process the inputs to download the new audio file with the segment replaced.
