10 Apr 2012 - PocketRTA Ultra for iPhone now Available

Pocket RTA Ultra is a highly portable award winning real-time spectrum analyser for the iPhone 4 & 4s.

Pocket RTA Ultra 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 Ultra 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.

PocketRTA Ultra brings you all the features you have come to expand from a 4Pockets RTA with the following great additional features.

-Variable Sample Rate from 8K to 48K.
-Added 8K 16K FFT Sizes for more accurate measurement.
-Improved 32bit floating point sampling.
-Smoothing (alternative to averaging).
-Improved SPL (Sound Pressure Level) display with LEQ mode.
-RT60 Calculations on Impulse Recordings.
-Variable definable decibel scales.
-Improved Signal Generator with log & linear sweep tones.
-Save & Load Profiles (for multiple calibration and graph settings).
