If your audio production is lacking that certain ‘crunchiness’, then man oh man have we got an easy-to-follow tutorial for you!
In today’s post we will walk our readers through the process of using our favorite free, open source audio editing software for Mac OS X, aka Audacity to boost bass levels, reduce treble and introduce a bit of (welcome) distortion, all in one fell swoop.
Looking for Setup instructions? Our recent Audacity 2.0.0 for Mac OS X Installation Tutorial should do the trick!
For today’s walk-through, we’ll be applying the Leveller effect using Audacity 2.0.0 (Windows 7) as run on Parallels; a virtual machine booted in ‘coherence mode’ running on a MacBook Pro.
Step 1: MP3 Download
Before one can edit their AudioAcrobat recording in Audacity, the first step is to make sure that the file resides on the hard drive of the computer on which editing will be performed.
1. Login to your AudioAcrobat account
2. Click Audio (L)
3. Click the Title of the Audio you wish to Download
4. Click Download Audio

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

Step 3: Highlight, Leveller + 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 Leveller 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 >> Leveller as seen below:
Immediately after selecting the Leveller effect, the following pop-up window will appear:
To best explain what exactly these settings represent, we’d like to share an excerpt from the Audacity manual regarding the Leveller effect:
The Leveller effect makes quiet passages louder and loud passages quieter. It does this in a way that is different from the Compressor effect. As a result it does add some distortion to the processed audio. The only way to be sure if the effect does what you want is to try it. For example, applying this effect twice at its Heaviest setting on a normally-recorded voice can produce an “air traffic controller” effect.
Click the Preview button to preview your equalization in real-time. Select OK to confirm your selection and Audacity will immediately render the effect.
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.
Well that was quick … we’ve already walked through the process of downloading and opening our file, applying the Leveller effect using Audacity 2.0.0 for Mac OS X and exporting the file for upload to the Web … and yet it seems as though we had just begun.
