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 the Applications folder in the dock. Open the software and click File >> Open, selecting the audio to be edited.

Step 3: Highlight, Change Tempo + Export
It really is that simple. Click and drag with the mouse cursor or for those keyboard enthusiasts out there use Shift + Left / Right arrow keys to make a selection.
For the Change Tempo effect, our readers will want to make sure to select the area which encompasses the intended duration for which the effect is to be applied.
Here our readers will want to select Effect >> Change Tempo as seen below:
Immediately after selecting the Change Tempo effect, the following pop-up window will appear:
Use the Percent Change value / slider to adjust the Length (seconds) or type in a custom value in either box for specific adjustments. Use the Beats per minute value boxes to set a custom BPM.
Use the Preview button to sample the effect before making a commitment and press OK to confirm the settings and apply the effect.
Note: This effect is very helpful if you enjoy the tone of your audio but still need to adjust the overall time aka tempo.
When satisfied, select File >> Export to save the newly edited version and head over to AudioAcrobat in an internet browser to begin the upload process.
