DesktopRTA is a real-time sound analyser for your PC with many features only found in much more expensive sound analysis software. DesktopRTA provides accurate graphical feedback suitable for amateur hi-fi enthusiasts, A/V engineers / installers and electricians.

DesktopRTA samples sounds from the input of your PC's sound card and then applies a Fourier Transformation to the samples to obtain a frequency spectrum. The result is an accurate representation of the sampled sound broken down into its frequency components.

This version is a complete full screen PC version of our very successful PocketRTA program.
