ASIO loopback driver

The ASIO loopback driver is a virtual ASIO sound card that sends its output directly to the input. You can compare it to a digital connection between the input and output of a sound card. This function is ideal for feeding the signal generator into the analyzer without cables. This virtual connection has an ideal frequency response and causes no noise. This ASIO driver also works with other ASIO software such as Cubase or WaveLab.

We offer a free version with stereo 16 bit and a commercial version with 192kHz 32bit and 64 channels.
