Pocket RTA is a new realtime spectrum sound analyzer for the iPad.
Pocket RTA provides fast and accurate spectrum analysis, for 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, 1/6, Oscilloscope, SPL and Spectrogram displays with ANSI A and C weighting curves. Use the iPad's multitouch interface to perform realtime 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, 1/6 or 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 CSV file or camera roll in JPEG format. These images can then by synced or transferred via FTP to your desktop PC for better analysis.
