Pocket RTA Ultra is a portable real-time spectrum analyser for Windows Mobile and iPhone devices, and is the latest addition to 4Pockets range of award winning RTA software packages.
PocketRTA Ultra samples sounds picked up by the built-in microphone on the Pocket PC and then applies a Fourier Transform to the samples to obtain a frequency spectrum. The result is an accurate representation of the sampled sound broken down into its frequency components.
PocketRTA Ultra gives total control over input sample rate and FFT length, so you can tailor the display to your needs. Sample rates up to 44Khz allow frequencies of up to 22Khz to be measured. Various display modes include, linear narrow band, logarithmic narrow band, Octave, 1/3 Octave, 1/6 Octave, Sample, SPL and Spectrogram displays with ANSI A and C weighting curves. PocketRTA Ultra allows real-time magnification (up to 250 times) of a selected frequency range. The touch screen allows selection of the nearest FFT point giving a display of it's frequency and decibel level. Up to 64 times averaging and variable decay settings allow more stable readings for fluctuating or unstable input signals whilst our unique noise cancellation system allows you to remove unwanted background noise.
Other features include screen rotation via the built in accelerometer, RT60 reverberation calculations, ANSI A, B and C weighting modes, internal signal generator and mush more.
