I just bought this app as another component to add to my mobile studio. I have to say it is an excellent application. Brilliantly responsive and really interesting to use. My plan is to use it to analyse the output from my work using my mobile studio to give me an idea on the range of the output. I’m looking forward to using it more in anger.

However, it is not an inexpensive application. I cost me about £20. I don’t mind as I think it is worth it to support developers who put these kind of apps together, and it helps me further build my mobile studio.

Here’s a few more of the technical details though:

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. (real-time analyser)

Features Highlight:

Waveform, fundamental frequency readout, plus either spectrum analyser 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:

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.
Spectrum analyser & 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.
Analyzer settings
Turn on/off grid lines.
HandDee preset analysis parameters for frequency and time averaging.
Three frequency scale selection.
15Hz-250Hz frequency range for woofer characteristic measurement.
15Hz-4KHz frequency range in monitoring musical performance or recordings.
15Hz-22Hz frequency range for all band response checking of hi-fi systems.

There’s a trial version available at palmgear. Try it out, it is fun to use.
