Detailed Description of Pocket RTA Professional 1.31
Pocket RTA Pro is a highly portable real-time spectrum analyser for your PC and Pocket PC.
PocketRTA Pro has many advanced features which are normally only found in much more expensive sound analysis software, providing fast and accurate spectrum analysis suitable for both amateur hi-fi enthusiasts and professional A/V engineers. Uses include system calibration, monitoring of noise levels and testing of audio equipment.
Pocket RTA Professional samples sounds picked up by the built-in microphone on the Pocket PC or the input of your PC's sound card 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.

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 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.
PocketRTA Pro features the ability to calibrate the display using a 1/3 Octave display in order to compensate for imperfections in frequency response of the internal microphone.
PocketRTA Pro also introduces a Compare / Transfer mode which allows you to compare a captured input signal against a live trace. The difference between the two traces are displayed using a 0dB reference point.
