FCL Audio Analyzer

1.Frequency test mainly tests the analytical ability of specified frequency for audio equipments. It contains standard sine wave audio files supporting for testing the frequency of 300Hz, 2000Hz, 8000Hz and 12000Hz. It also supports custom output and the user can adjust the frequency of the audio device which will be analyzed by the frequency testing tool.

2.Frequency response test includes frequency response and phase response test. Frequency response can measure the response and distinguish ability of audio equipments for signal. Measurement of phase response is meaningful for judging the quality of frequency divider design and determining the relative position of unit sound center. These parameters are related to the design and production of sound equipments and it is very important for user to balance system on different occasions.

3.Signal-noise ratio test can measure the ratio of introduced noise when the audio equipment plays the normal signal. The test result can reflect the quality of audio equipment.

4.This tool distinguishes the test between left and right channel so that the audio performance of mobile devices is more accurate."
