Suppose you have a record in Audacity and you wish to decrease its speed for editing purposes exclusively. Once you’ve selected the desired section, you can navigate to the “Effect” menu and choose “Change Speed” to adjust the speed until the audio plays at the desired slower pace. However, after completing the editing process, you may notice that the tempo and pitch of the song have become distorted. This leads to the question: How can one correctly slow down audio in Audacity?

Audacity is a freely available and open-source software for recording and editing audio. It can be used on Windows, macOS/OS X, and Unix-like operating systems. To address the aforementioned concern, the key lies in understanding the distinction between changing speed and tempo. The following instructions will outline a few steps to help you properly slow down audio using Audacity.

Step-by-step Guide to Slow Down Audio in Audacity

Step 4. Click File > Export as MP3, WAV, etc.

Note: Altering the speed will have an impact on both the pitch and tempo of the track. For instance, if you slow down a song sung by a female vocalist, it may end up sounding like a male singer. This technique is commonly employed when creating remixes or incorporating samples into projects where pitch and tempo variation is desired. However, if your goal is to change the tempo without affecting the pitch, an alternative approach must be taken.

How to Slow Down Audio without Changing Pitch

Audacity provides a straightforward method to adjust audio speed while keeping its pitch. Here’s a step-by-step guide:

1. Click File > Open to choose audio.

2. Click and drag to choose the area you want to slow down. Or choose Edit on the top bar > Select All when you intend to target the entire track.

3. Click Effect > Change Tempo. Then drag the slider to the left however much you want to slow the track down. This function can help you slow down the audio track while not changing the pitch. You can also achieve the same effect by typing in a specific number of seconds you’d like the audio to go.
