PassMark SoundCheck is a utility that you can use to test and to analyze the performance of your PC soundcard, speakers and microphone. It allows you to know their capacity and to adjust their settings for better sound quality. Thus, you can create tonality tests with different sample rates and use Spectrum analyzer to see the result. If you like, it is also possible to adjust the sample rate of your PC, the play back mode (stereo, mono) of a recording, the rhythm and to test the output devices (if several ones are installed), etc. Finally, this software is compatible with Windows 98 or higher and can be used freely for 30 days.
