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:

• Engine Crank and Cam Sensor Simulator, with custom RPM test schedule. Now supports single or dual cam Variable Valve Timing (VVT).
• DaquinOscope turns an inexpensive Arduino board into a high-speed multi-channel oscilloscope and function generator.
• DC_Chart_Recorder records up to 8 channels from Arduino or Numato.
• Arduino_Counter, Arduino_Meter, Arduino_Oscillators, Arduino_Race_Timer, and Arduino_RCtime macro mini-apps.
• Numato_Meter and Numato_Oscillator macro mini-apps.
• Event Triggering options for launching Daqarta operations (typically macros) via key press or sound card input, or via external Arduino or Numato device detection of switch, resistance, digital input, or analog voltage changes.
• Triggered_Burst macro can be used by above Event Triggering options to create single "one-shot" bursts or burst trains.
• Auto_Recorder sound-activated recorder with adjustable start/stop parameters.
• Arb_From_Equation with 47 Arb (arbitrary waveform) files now included in the Daqarta distribution, plus waveform images in Help with full code you can modify to create your own Arbs.
• Convert BMP image to WAV file, whose spectrogram is the original image... in color.
• Audio phase audibility demonstration.
• Missing Fundamental perception experiments.
• MIDI Music Creation:
  • DaqMusiq running GlossyTracks plays over 4 billion unique tracks... and they all have names!
  • Music_From_Anything creates live music from any source: Image, data file, text, sound recording, live microphone, mouse-drawn, or random. Editable features, no musical ability required!
• Compute response curves from equations for equalization, filters, etc.
• LCR Meter measures inductors, capacitors, resistors, ESR, DF, Q.
• HMS Timer / Stopwatch / Alarm all-in-one timer.
• Multi-Channel Meters, 10 measurement types plus plotting and logging.
• File Navigator for cursor-scrolling through large files.
• Channel difference (L-R, etc).
• THD and IMD distortion meters, including low frequency THD meter.
• Precision phase meter/plotter/logger.
• Pulse meter (4-channel pulse width, duty cycle, frequency).
• FFT Filter demo.
• Lissajous Figures.
• Multi-speed chart recorder.
• WAV file Stereo-to-Mono conversion.
• Arbitrary Random Distributions.
• Real-time Thermocouple voltage to temperature.
• Phantom Signals auditory hallucination.
• Auditory beats demo, including:
  • Monuaral beats
  • Binaural beats
  • Isochronous beats
  • Surf sounds
  • Moving noise
  • Jet sounds
  • Middle ear thumping

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.
