Others (such as noise analysis or analyzing live or recorded music) require no test signal. TrueRTA Self Test of an E-MU 0404 USB sound system, shown in Line Mode Some of the above applications require the use of the analyzer in combination with a test signal from the generator. The latter settings are appropriate for highly accurate frequency response measurements. Longer samples provide increased low frequency resolution with the tradeoff of slower updates. The size of the waveform sample is variable so that shorter samples can be used where a high frame rate is required, as in sampling live music. The audio spectrum analyzer shows the changing spectrum of live input signals up to 48kHz (half the maximum sampling frequency).
Here are the components that make up TrueRTA: High Resolution Audio Spectrum Analyzer TrueRTA 's audio spectrum analyzer software shows you a detailed picture of what you're hearing in real-time, that is, as it happens.
The screen shot below shows TrueRTA evaluating the performance of the E-MU 0404 USB sound system with a 1kHz sine wave where the 1 kHz distortion components are seen to be below -100 dB (i.e., less than 0.001%). Study the harmonic structure of musical instruments. Analyze the distortion characteristics of audio equipment. Measure the frequency response of various types of audio equipment. Observe the frequency characteristics of recorded music or other recorded audio. Study the noise characteristics of acoustic environments or electronic gear. Combine individual loudspeaker measurements into a spatial average frequency response measurement.
Measure the frequency response of a loudspeaker system using either pink noise or Quick Sweep.
TrueRTA runs under Windows Vista, 7, 8 and 10. TrueRTA turns your PC into a powerful audio test system normally seen only in better audio research and design laboratories.
