TrueRTA
Andersonville, Tennessee, USA
What it is
TrueRTA is Windows software for testing and evaluating audio systems with a PC that has basic sound capability. Its instruments include a real-time spectrum analyzer, low-distortion signal generator, digital level meter, crest-factor meter, and dual-trace oscilloscope. The analyzer displays live input spectrum up to 48 kHz; shorter samples update faster, while longer samples provide better low-frequency resolution. The maker describes using it to measure speaker frequency response, combine speaker readings into a spatial average, study noise, and analyze equipment distortion. The signal generator produces sine waves from 5 Hz to 24 kHz and pink noise. Higher levels add a digitally generated logarithmic sweep from 10 Hz to 48 kHz. Users can add their choice of measurement microphone, preamp, and USB interface. All four levels include data import and export, project files for data and notes, and report printing in color or black and white. Level 1 is free and never expires; paid levels are one-time purchases at $39.95, $69.95, and $99.95.
