The HandDee Spectrum Analyzer generates real-time fading frequency spectrum or scrolling spectrogram on the pocket PC. An intelligent wave monitor window gives you a stable waveform display. Smart peaking envelopes are provided for music monitor and audio system calibration. HandDee features makes speaker system frequency response & IM (intermodulation) distortion check a snap.
Better than standalone handheld or portable RTA (real-time analyser).

Features Highlight:

• Works with MediaPlayer and most MP3 players running in the background (Model dependent).
• Waveform, fundamental frequency information readout, plus either spectrum analyser or spectrogram display.
• Fast update rate. Normally about 6-20 spectrum plots per second depending on Pocket PC model.
• HandDee one-touch background sound removal substracts background sound level to reveal the real signal.
• The program intelligently subtracts white noise in the environment as well as digitising noise and interference of the Pocket PC.
• HandDee one-touch auto dB ranging let's you get the best view of the spectrum.
• Fading effect reveals trends in waveform and spectrum plots.
• Transition effect has excellent quality and is even better than long persistence phosphor used in oscilloscopes.
• Pause function for detailed inspection of waveform, spectrogram or spectrum display.
• Support for Xscale, ARM, MIPS (Casio E-115 & E-125) and SH3 (HP 54x) machines.
• Small program size.
• Free Sound Test Files for download

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.
