Introduction.

Audio Analyzer is the App that allows you to perform some technical measurements of quality of the audio equipments such as amplifiers, pre-amplifiers, loudspeakers, headphones, receivers, microphones, equalizers, mixers as well as the whole audio track that including all of these audio components. Also the App is capable to measure audio parameters of separate electronic circuit components such as filters, transformers, operational amplifiers in the frequency range from 20 Hz up to 22050 Hz.

The following audio characterictics can be measured by this App: frequency response curve, dynamic range, harmonic distortion, intermodulation distortion and other non-linear distortions.
The idea of the App consists of receiving the input feedback audio signal and compare it with the output audio signal that the same Android device is generating.

The 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.

It takes less than one second to build the frequency response curve in the full audio range of 20-20000 Hz in 2.5 Hz resolution with the wideband audio signal generated by the same device.

An input and output of the signals are provided through the audio jack of the device. The microphone line is used as the input, the headphones line as the output.

Features.

  • Completely NO ads.
  • Selectable frequency resolution between 2.5 and 10 Hz.
  • Separate analysis in the left and right audio channels is possible.
  • Fine-detailed viewing the frequency response spectrum with up to 16384 spectral points by zooming and dragging.
