Core Sound offers audio testing services to support new product development, equipment evaluation, maintenance and calibration.
Are you designing a new analog, digital or mixed analog/digital audio device?
Do you need to test it but don't have the resources?
Are you modifying or upgrading your studio and want to quantify the improvement?
Do you need to match two or more pieces of audio equipment?
Does your soundfield sps200 a-format microphone need calibrating?
