Audio Signal Generation and Acquisition ActiveX Control
Raga is an ActiveX control for generating and recording audio signals using a standard PC sound card.
Raga can generate sinusoidal, rectangular, triangular, multi tone, white and pink noise signals as well as
arbitrary waveform signals and signals stored in wav-files. Signals can also be combined to form complex
sequences and composite signals. Raga's triggerable recorder can record up to 16 channels simultaneously
and saves data to disk or memory. Each of the sound card's inputs and outputs can be calibrated individually.
