Measurement card support for extended frequency rangeWinAudioMLS has many applications beyond audio. The powerful analyzer is widely used for e.g. noise+vibration in the sub and supersonic area. Many of these industrial applications require a frequency range from DC to 250kHz. Typical soundcards (example) have a low cut filter with -30dB at 1Hz. In addition the gain is not deterministic and requires calibration. Therefore there are limitations for low frequencies (1-20Hz) in the important vibration area. WinAudioMLS supports the DS2200 and DS1M12 "Stingray" measurement card from www.usb-instruments.com. We offer a driver that allows to the powerful analysis features of WinAudioMLS with these cards. The advantage compared to soundcards is a frequency response down to DC and a preamplifier with controllable gain. The benefits of this device are:
