Save Changes to a New File

If you want to save the changes you made, export the audio as a new file. Here's how:

  1. Select File > Export and choose a format type.

    Whichever file format you select, you have the option of changing it in the window that appears.

  2. Type a name for your file in the File name text box and select Save.

If you see a message saying that you can’t save in the MP3 format or you receive a lame_enc.dll error, download and install the LAME encoder plugin. For more information on installing this, read this Audacity tutorial on converting WAV to MP3 (scroll down to the LAME installation section).

Step 2: Open in Audacity

Now that the file our readers wish to edit is on their computer’s hard drive, they will want to open the file with Audacity.  Right-click the file and choose Open With and select Audacity from the list.  Don’t see it listed?  Open Audacity from Programs folder in the Start menu.  Open the software and click File >> Open, selecting the audio to be edited.

Once the file opens in Audacity, our readers will see something like this:

Use high quality stretching (slow)

If this checkbox is enabled, the same SBSMS high quality algorithm is used that is used in the Sliding Stretch effect. Change Pitch will process much more slowly if this checkbox is enabled, but the exact length of the selection will be preserved. For small to moderate tempo changes, the resulting quality will usually be higher, especially with percussive music (such as piano music).

How to change BPM in Audacity?

Whenever you are using audacity to mix two or more sound clips or are using a sound mixer, you might face the problem of excessive difference in the tempo or BPM in the audio clip. So, the question which arises over here is that how can we change the tempo or Beats per minute in audacity? Well, we have prepared some step by step guide for you by which you can easily change the BPM from audacity:

Step 1 – Launching the app

The first step which you have to undertake is that you will need to launch the audacity app on your desktop.

Step 2 – Opening the audio clip

Now, once you have launched the audacity app, you can now initiate the opening of the audio clip. In order to open the audio clip, you will need to click on the tab showing File and once the drop down menu comes out, you will need to click on Open and select the appropriate audio clip.

Step 3 – Click on Effects

Once you have opened and selected the audio files for which you want to change the BPM, you will now need to click on the tab showing “Effects”. Once you have clicked on Effects, you will need to select the tab showing “Change Tempo” from the drop down menu.

Step 4 – Adjust the tempo

Here, you can enter the percentage change of the tempo or beats per minute, according to your requirement. However, one thing which you should be careful in this step is that if you are working on a multi-audio project, you should adjust the beats per minute in such a way that there should be no lag or difference in the tempo of both the audio clips. You can also select a particular time interval in the audio clip and change the tempo of that particular time frame.

Step 5 – Change the pitch

Apart from this, you can also alter the pitch as well as both pitch and tempo together in the audacity app. You will just need to select the tab of “Effect” and then, click on “Change Pitch” from the drop down menu to adjust the pitch rate of the audio clip.

Test 2: Pitch

Comparing this screenshot to the original, we see

Comparing this screenshot to the original, we see that the Initial and Final Pitch values have been moved to -50% and +100%, respectively.  From here, select OK to confirm changes.

Looking at the waveform below, we don’t see very much of a change from our original, which is a good thing, as the only thing changing would be Pitch, as opposed to the previous example’s Tempo change.

Listening to the audio, we do hear a BIG difference as the low beginning of the beat steadily pumps along, winding up to a high-pitched finish!
