HandDee-SA (UIQ) Spectrum Analyzer - With the HandDee Spectrum Analyzer, a PDA becomes probably the world's cheapest, smallest and easiest-to-use color graphic handheld real-time audio spectrum analyzer, not to mention the expensive & bulky portable RTA.
The software generates real-time fading frequency spectrum or 1/3 octave ISO bar. An intelligent wave monitor window gives you a stable waveform display. Smart peaking envelopes are provided for music monitor. HandDee features makes speaker system frequency response & musical recordings check a snap.
Waveform Display features
HandDee intelligent display with automatic triggering shows stable sound samples upon receiving stable sound input.
HandDee automatic scaling to expand low level sound signal for easy examination.
Digital frequency readout and marking on spectrum
HandDee fundamental frequency measurement with overtone rejection.
Loudest note display when multiple sounds detected.
Accuracy of about 0.5% or 1Hz, 10 times better than Fourier Transform./ul>
Spectrum & ISO bar Display features
Grid lines can be turned on or turned off.
HandDee musical sound peak power envelop.
1/3 octave ISO bar display.
Turn on/off grid lines.
HandDee preset analysis parameters for frequency and time averaging.
