Sample Rate and Bit Depth settings are found in a drop down menu in the audio or sound control panel
of your computer. You can adjust these variables to fit your needs. Select a lower sample rate for podcast
recording, when it is important to have a smaller file for easy download. Select a higher sample rate for
music and more dynamic recordings.
Tip: Record at a higher sample rate and bounce down to an M4A for a file with the highest sound quality
at a manageable size.
Tip for PC users: Make sure that the sample rate and bit depth microphone settings, found in the sound
control panel of the computer, match with the sample rate and bit depth selected in your software.
