How to Change Bitrate in Audacity

The audio bitrate in a music editing program should be adjusted before any work is started on an electronic composition. The bitrate determines the amount of information each second of sound can hold. The higher the bit rate the less likely your song will have distortion and the quality of the audio will be higher, but it also requires more memory on your computer. Audacity will allow you to choose three main bit rates: 16, 24 and 32. Even though a CD will only allow for 16-bit audio, it is still beneficial to record at a higher bit rate when possible.

Step 1

Start Audacity by double-clicking on the program icon. This will open up your default settings and allow you to choose a new or existing project.

Step 2

Select your options for a new file, or open a file you currently are working on. You do not need to have any music recorded before you change the bitrate.

Step 3

Click on the main Audacity menu and a drop-down menu will appear.

Step 4

Select preferences from the drop-down menu. A new dialog box will appear with several options on the left. The options include devices, playback, recording, quality and several other options.

Step 5

Click on the Quality option. In the panel on the right there will be options for sample rate and default sample format. The sample rate should be at 44100 Hertz or higher for CD-quality sound. The Default Sample Format is where you can change the bit rate. Select from the 16-, 24- or 32-bit drop-down menu.

Step 6

Click OK. You can now start using Audacity in the bitrate you have selected.
