The audio quality of an MP3 file is determined by the sampling rate, which for CD-quality audio is 48 kHz. Testing an audio file may require you to use a variety of sampling rates, which may include 8 kHz, or 8 bit. This will result in a mono, or one-channel audio file. Converting MP3 files to 8 bit will require using a software program with an option for 8 kHz, such as the Easy Hi-Q Converter.
