## 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.

## Inputs

- **Base Audio** (file): Select the base audio file
- **Replacement Audio** (file): Select the replacement audio file
- **Replace Start (hh:mm:ss\[.ms\])** (text): e.g., 00:00:10
- **Replace Duration (seconds or hh:mm:ss\[.ms\])** (text): e.g., 5

## When to use

- When correcting errors or unwanted sections in audio recordings without re-recording the entire 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.

## Use cases

- Editing out mistakes or background noise from interview or podcast recordings.
- Updating outdated segments in educational or corporate audio presentations.
- Customizing audio files by inserting new intros, outros, or sound effects at exact points.
