- **Keywords:** audio, speed, resample, pitch

## Overview

Varispeed-style change: resamples the audio so speed and pitch move together, like tape speeding up or slowing down.

## Inputs

- **Audio File** (file): Select an audio file
- **Speed Factor (resample)** (number): 1.2
- **Output Format** (select)

## When to use

- When you need to adjust the tempo of an audio recording without separating pitch and speed changes.
- For creating varispeed effects in audio production, like tape-style speed adjustments.
- To quickly speed up or slow down audio for review, practice, or editing purposes.

## How it works

- Upload an audio file in a supported format such as MP3, WAV, or AAC.
- Set the speed factor between 0.25 and 3 to increase or decrease playback speed.
- Choose an output format like MP3, FLAC, or WAV for the processed audio.
- Process the file and download the resampled audio with the new speed and pitch.

## Use cases

- Adjusting the tempo of music tracks for practice, remixing, or creative projects.
- Speeding up podcasts or audiobooks to save time during listening.
- Slowing down audio recordings for detailed analysis or learning purposes.

## Frequently asked questions

### What audio formats can I upload?

You can upload common audio formats including MP3, WAV, AAC, and others, with a file size limit of 200 MB.

### How does resampling affect pitch?

Resampling changes both speed and pitch together; increasing speed raises pitch, and decreasing speed lowers it.

### Can I change speed without altering pitch?

No, this tool uses resampling, so pitch always changes with speed. For pitch-independent adjustments, use a time-stretching tool.

### What is the range for the speed factor?

The speed factor can be set from 0.25 (slower) to 3 (faster), with a default of 1.2.

### Is there a limit on audio file length?

There is no specific length limit, but files must be under 200 MB in size.
