The minimum requirements to use TrueRTA are a PC witha 500 MHz Pentium III processor, 64MB RAM and full duplex 16 bit sound capability running Windows XP, Vista or Windows 7 / 8 / 10 Selected functions are displayed in the same window as the oscilloscope or spectrum analyzer display. TrueRTA Quick Sweep of a Highpass Filter (using sound card calibration, white background)Ĭrest Factor in mV/mV (ratio of peak to rms level) Only the response of the actual filter is measured when sound card correction is employed. Note the total absence of any sound card response error. When loaded by the input impedance of the sound card the series capacitor forms a high pass filter with -3 dB frequency at around 300 Hz. TrueRTA Quick Sweep WITH Sound Card Calibration (self test of E-MU 0404)īelow is a Quick Sweep measurement of a high pass filter created by inserting a 470 pF capacitor in the test loop. The response of any system you now insert in the test loop can now be measured very precisely plus or minus. Note that the response of the sound card has been removed from the measurement so that a self test of the sound card now shows a flat response. TrueRTA Quick Sweep WITHOUT Sound Card Calibration (self test of E-MU 0404, dark gray background)īelow is TrueRTA with Sound System Calibration switched on. Below is the measured response of an E-MU 0404 USB audio interface at 96 kHz sampling frequency. TrueRTA's Quick Sweep employs a short digitally generated sweep (chirp) to measure the frequency response of electronic and acoustical systems. Others (such as noise analysis or analyzing live or recorded music) require no test signal. Some of the above applications require the use of the analyzer in combination with a test signal from the generator. TrueRTA Self Test of an E-MU 0404 USB sound system, shown in Line Mode 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. Measure the frequency response of various types of audio equipment.Īnalyze the distortion characteristics of audio equipment. Observe the frequency characteristics of recorded music or other recorded audio. Study the noise characteristics of acoustic environments or electronic gear. Measure the frequency response of a loudspeaker system using either pink noise or Quick Sweep.Ĭombine individual loudspeaker measurements into a spatial average frequency response measurement. Observe the frequency characteristics of live music in real time. Here are some of the things you can do with a real time analyzer: The test instruments found in TrueRTA include: 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.
