Publisher Description



Pocket RTA is a highly portable award winning real-time spectrum analyser for the iPhone.

Pocket RTA 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.

PocketRTA samples sounds using either internal or external microphones 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.

Various display modes include, linear narrow band, logarithmic narrow band, Octave, 1/3 Octave, Oscilloscope, SPL and Spectrogram displays with ANSI A and C weighting curves. Use the iPhone's multi-touch interface to perform real-time magnification of displays. The touch screen allows selection of the nearest FFT point giving a display of it's frequency and decibel level. Up to 16 times oversampling allow more stable readings for fluctuating or unstable input signals whilst our unique noise cancellation system allows you to remove unwanted background noise.

PocketRTA features the ability to calibrate the display using a 1/3 Octave display in order to compensate for imperfections in frequency response of both internal and external microphones. The program automatically detects and switches between both sets of calibration data.

Pocket RTA has the ability to capture up to 3 input signals and overlay them as a reference over live input. All display modes allow exporting of graphed data to the camera roll in JPEG format. These images can then by synced to your desktop PC for better analysis.
