Manufacturer: True Audio

TrueRTA is available in 3 levels that provide 1/3rd, 1/6th and 1/24th octave real time analysis of audio signals. This is the 1/6th octave (Level 3) version of TrueRTA. TrueRTA's audio spectrum analyzer software shows you a detailed picture of what you're hearing in real-time, that is, as it happens. You can create your own professional measurement system starting with TrueRTA software on your PC. Then add the measurement microphone, preamp and USB interface of your choice. TrueRTA accurately tests audio systems using a Windows PC with basic sound capability. TrueRTA turns your PC into a powerful audio test system normally seen only in better audio research and design laboratories. TrueRTA applications: Measure the in-room frequency response of a loudspeaker system using either pink noise or Quick Sweep. Save measurements in up to 20 memories for later recall and overlay comparison. Combine individual loudspeaker measurements into a spatial average frequency response measurement. Observe the frequency characteristics of music, sound, or noise in real time. Study the noise characteristics of acoustic environments or electronic gear. Observe the frequency characteristics of recorded music or other recorded audio. Make high resolution measurements the frequency response of various types of audio equipment. Analyze the distortion characteristics of audio equipment. Use as a voice and music learning aid. Study the harmonic structure of musical instruments.
