It is now possible to increment the gain in 1db increments up to +/- 100db. Pink Noise has also been added to the Signal Generator.

Again this can be saved or exported for use in external packages.

A smoothing option has also been added (wide band averaging) to remove unwanted spikes and make the display more readable.Īnother new feature is the ability to capture a peak trace over time. The difference between the two traces are displayed using a 0dB reference point making it ideal for calibrating EQ''s. PocketRTA Pro also introduces a Compare / Transfer mode which allows you to compare a captured input signal against a live trace. You can even take snapshots of the screen which are saved in BMP format. Captured traces can be saved and later loaded as a reference or exported to ASCII text for use in packages such as Microsoft Excel. 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.Īnother new feature is the ability to capture any input signal and overlay it as a reference for a live signal. 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. The touch screen allows selection of the nearest FFT point giving a display of it''s frequency and decibel level. PocketRTA allows real-time magnification (up to 250 times) of a selected frequency range. 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. Sample rates up to 44Khz allow frequencies of up to 22Khz to be measured.

PocketRTA gives total control over input sample rate and FFT length, so you can tailor the display to your needs. The result is an accurate representation of the sampled sound broken down into its frequency components. PocketRTA 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. Uses include system calibration, monitoring of noise levels and testing of audio equipment. 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. Pocket RTA Pro is a highly portable real-time spectrum analyser for your PC and Pocket PC.
