Daqarta v11.7.0

Stereo inputs and up to
EIGHT independent output channels!

DAQARTA turns your Windows sound card into a precision laboratory instrument, loaded with advanced features. Put your sound card to work!

Now with Arduino and Numato support.

Besides all its built-in standard features, Daqarta contains a macro language that allows you to create your own dedicated applications with customized displays. An ever-growing collection of Macro Examples and Mini-Apps is included. You can use these as-is, or modify them as desired. NOTE that you don't need a license to use most of these, even past the trial period, only those that use sound card inputs:

Daqarta also allows custom reports, custom data logging, and remote control by an external program. Sample rates up to 256 kHz are supported, as well as slow input sampling (down to one sample per day or slower) while maintaining full output sample rates for simultaneous high-frequency stimulus generation. Allows slow scroll rates for chart recorder display of DC signals like temperature and pressure, and provides circuits to allow ordinary sound cards to handle DC measurements.

Built-in Help is always available. Right-click any control to jump to its Help topic, over 950 in all. Need more help? Contact Us... we respond to all questions, usually in 24 hours or less.

Download Daqarta v11.7.0 now and try it FREE for 30 sessions or 30 days.

You can purchase Daqarta for only
US $29.00 (Personal/Hobby)
US $99.00 (Professional)
These are permanent licenses that will work with all future versions of Daqarta... you only pay once.

But, even if you don't buy, Daqarta will keep on working with only the signal inputs and Pro features disabled. Essentially, it reverts to a freeware 8-channel signal generator, plus advanced Daqarta features like:

Arduino and Numato macro mini-apps like DaquinOscope, DC_Chart_Recorder, Arduino_Counter, Aruino_Meter, Arduino_Oscillators, Arduino_Race_Timer, Arduino_RCtime, Numato_Meter and Numato_Oscillator.

DaqMusiq allows creation of unique ever-changing musical performances that you can save, load, and exchange with other users, or record to standard MIDI files.

Data file operations allow you to save signals for later analysis, as single-screen or arbitrary-length ( DDisk) files. Even after the trial period, this allows you to to create your own Arb or Play Wave files for the Generator, for example.

You can open saved files, including standard .WAV files collected elsewhere, to analyze waveform, spectrum, or spectrogram displays of file data. Even many "unsupported" formats can be opened via manual selection of format parameters.

Extensive Help includes tutorials on Fourier Transforms, synchronous waveform averaging, applications, and much more.
