Waavebox (TM)

Versatile, easy to use software based signal generator - - invaluable for audio testing and laboratory applications.

Waavebox was designed after considering the analog, bench-top function generator paradigm - plus: user configurable slide controls and push buttons, with keyboard support for precision settings.

General Information

Uses Macintosh built-in (or third-party) sound output capabilities for signal generation (and integrated, full-duplex analysis from Mac the Scope) User-friendly, interactive interface makes obtaining various output waveforms simple Default frequency range 20 Hz to 20 kHz (control limits can be set to be outside this range); waveforms from millihertz to ultrasonic (limited by output device) Precision, low-distortion waveforms computed with 64-bit math (here is a plot illustrating the spectral purity) Interactive, flexible controls with selectable "analog" (continuous) or "digital" (discrete) emulation modes, linear or logarithmic scales Controllable via AppleScript DIGITAL LOCK option matches binary sequence length to other analysis software; avoids frequency domain scallop loss and leakage effects On line help in main Console (just move mouse over item, for information about item)

Features

Sine, Triangle, Sawtooth, Square / Pulse (bipolar or unipolar, with variable period and pulse width), Inverted Polarity, Adjustable Phase Offset Dither option for periodic waveforms improves waveform quality Almost any audio frequency (6 digits of precision) may be obtained - - waveform frequencies are not constrained to even divisors of the sample rate Single- frequency or Swept waveforms Multi- Harmonic (independently adjustable amplitude, frequency, phase) super- or sub- harmonic waveforms, up to 128 summed harmonics White, Pink or "Red" Noise; selectable 1/3 octave bandpass filtering with band centers from 20 Hz to 20 kHz: single band or combinations of bands, boost or cut, "brick-wall" elliptical filters with 16-pole cutoff slopes and flat tops within 0.05 dB for single filters, 0.5 dB for summed filters Super flat Pink noise generator, better than other sources (CD recordings, hand-held generators, etc.)

Waavebox Plugin Edition is included with Mac the Scope. A demo also is included with the Mac the Scope Demo / Updater package.

For a limited time, Waavebox and Waavebox Lite orders include a free copy of Mac the Scope SE!
