# Slow Down Audio Without Changing the Pitch

Learn a fast guitar solo, practise a language, or transcribe a fast talker. Slow the recording down while voices and instruments stay in tune.

**Quick answer:** To slow down audio, open the file, keep 0.75× (or choose 0.9× or 0.5×) and press Slow it down. With Keep the pitch on, the sound is time-stretched so it stays in the same key; switch it off for the deeper tape-slowdown effect. The result is saved as MP3, M4A or WAV, and nothing is uploaded.

## How to use it

1. Choose the song, lesson or recording.
2. Keep 0.75×, or pick 0.9× for a gentle slowdown or 0.5× for half speed.
3. Leave Keep the pitch on so it stays in tune.
4. Press Slow it down, listen, and download the slower file.

## Which speed for what

| Speed | Good for |
| --- | --- |
| 0.9× | Fast podcasts and lectures, still natural |
| 0.75× | Transcribing, language learning, practising along |
| 0.5× | Working out fast solos and tricky passages note by note |

Any speed from 0.25× to 4× is possible with Other.

## Pitch kept or not

With Keep the pitch on, the audio is time-stretched: small slices of sound are repeated and blended so the playback is longer but every note stays at its pitch. The stronger the slowdown, the more you hear a slight echo or smear, especially on drums. With it off, the audio is simply played slower, like a record at the wrong speed: the pitch drops, which some people use for slowed-and-reverb edits.

## Faster, and videos

## Frequently asked questions

### How do I slow down a song without changing the pitch?

Open it here, choose a speed below 1× and keep Keep the pitch on. The song plays slower in the same key.

### Why does very slow audio sound echoey?

Time-stretching repeats small slices of sound. At 0.5× and below that becomes audible, especially on percussion.

### Can I make the slowed version deeper?

Yes. Switch off Keep the pitch and the pitch drops with the speed, like a slowed-down tape.

### Is my audio uploaded?

No. It is processed in your browser.
