Audio sounds bad Check in the top left corner of the application that the MV88 is fully plugged in and recognized.
The audio may be from the built-in microphone.

Headsets with microphones override the MV88 as the audio device. Use the included headphone
monitor adapting cable to disable interference from other microphones.
Audio is distorted Use the audio meter to ensure that volume peaks are within the target range. If level is reaching
the red peak indicator of the input meter, turn the gain down.

Sampling Rate and Bit Depth
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 record-
ing, 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 micro-
phone settings, found in the sound control panel of the computer, match
with the sample rate and bit depth selected in your software.
