AUDIO TESTING AT CORE SOUND
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?
Consider using Core Sound to do your audio testing. We have (and
maintain) some of the finest audio test equipment made in the world.
And we have the expertise to apply them to your needs.
Please call Len Moskowitz at 201-801-0812 to discuss what we can do for
you.
