3. Wait until the app finishes analyzing your audio device.
4. View the results and have fun.
You can use the app to perform a quality test on your audio equipment.
The following parameters are available:
Frequency response curve: This is a graph that shows the frequency range of the sound that is being outputted. This range is defined in terms of the percentage of the total frequency spectrum.
Dynamic range: This is the ratio of the maximum level of the sound to the minimum level of the sound.
Harmonic distortion: This is the ratio of the second harmonic distortion to the first harmonic distortion.
Intermodulation distortion: This is the ratio of the third intermodulation distortion to the second intermodulation distortion.
Other nonlinear distortions: This is the ratio of the nth harmonic distortion to the nth intermodulation distortion.
The Audio Analyzer app is capable to form the output audio signal with practically ideal rectangular spectral characteristics in the user-defined frequency band in the two separated bands plus some fixed frequencies simulanuesly.
