8-Channel Sound Card Signal Generator Features


[Daqarta Generator Waveforms (50K image)]

Dreaming of the ultimate audio signal generator?

Imagine a precision generator, packed with features, capable of creating all kinds of standard waveforms or arbitrary shapes. With drift-free, low-distortion signals, and a resolution of 0.0001 Hz and 0.05 degrees.

Imagine a generator that can use recordings such as speech, music, or animal calls as signal sources, played with adjustable speed and direction.

Imagine that it can also create random noise with controlled characteristics like white, Gaussian, pink...
... or band-limited, with spectra you can manipulate like this:

Imagine a generator with built-in modulators: Amplitude, frequency, phase or pulse-width modulation, plus bursts and sweeps. Use any or all at the same time.

Now imagine EIGHT of these generators, with perfect tracking: Set a sine on one and a cosine on another, and they stay in sync forever. Combine a white noise source with an identical source that is delayed in time, and the result is comb-filtered noise. Modulate the time delay and it becomes a "jet takeoff" sound.

Or use the output of one generator as the modulation source for another: A pulse waveform, with frequency, phase, or pulse-width modulation driven by a noise source from another generator to give controlled jitter. Amplitude modulation of that noise source to vary the jitter strength, controlled by another generator stepping through an arbitrary file holding a specified test sequence.

The cost of this lab full of equipment? FREE!

But it's even better than a lab full of hardware, because everything is done with your sound card. No matter how complex the setup, it can be saved and loaded instantly... perfectly repeatable every time.

Just download Daqarta and put your sound card to work. After the 30-day / 30-session trial period expires, a few of Daqarta's other features will stop working ( inputs, Auto-Calibration, macro file saves, Spectrum Limits, and memory trace arrays)... but the signal generator is yours to keep on using forever !
