## Overview

The Audio Tempo Change tool allows you to adjust the playback speed of audio files—speeding them up or slowing them down—without altering the pitch. It's designed for musicians, podcasters, and anyone needing precise tempo modifications for practice, listening, or editing.

## Inputs

- **Audio File** (file): Select an audio file
- **Tempo Change (%)** (number): e.g. 20 for +20%, -15 for -15%
- **Output Format** (select)

## When to use

- When practicing musical instruments at a slower tempo to master difficult sections without changing the key.
- To accelerate audio content like podcasts or lectures for more efficient listening.
- When synchronizing audio with video projects that require timing adjustments for better alignment.

## How it works

- Upload your audio file in a supported format, such as MP3, WAV, or AAC.
- Specify the tempo change percentage, ranging from -75% (slower) to +300% (faster).
- Select an output format from options like MP3, FLAC, or WAV to suit your needs.
- Process the file and download the audio with the adjusted tempo.

## Use cases

- Musicians slowing down complex solos or passages for detailed practice sessions.
- Podcast listeners speeding up episodes to consume content more quickly while retaining clarity.
