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.
More HandDee than standalone handheld audio RTA.

Features Highlight:

• Waveform, fundamental frequency readout, plus either spectrum analyzer or1/3 octave ISO bar display.
• Fading reveals trends in waveform and spectrum plots.
• Transition effect is even better than long persistence phosphor used in oscilloscopes.
• Pause function for detailed inspection of waveform or spectrum / ISO bar display.

Other Features:

1. 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.
2. 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.
3. 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.
4. Analyzer settings
   • Turn on/off grid lines.
   • HandDee preset analysis parameters for frequency and time averaging.
   • 500Hz frequency range for bass characteristic measurement.
   • 4KHz frequency range in monitoring speech, musical performance or recordings.
