Speaker Check Utility

In Progress

I need a software utility (exe file) to test speakers. The speakers are normal home speakers (not audiophile ones).

What I need to test are:

- need to check if the speakers are functioning properly by giving a left-or-right signal.

e.g. we can use [url removed, login to view] to check the left speaker and [url removed, login to view] to check the right one.

The content of each mp3 is recorded appropriately to perform such function.

- need to check the polarity of the speakers (in-phase or out-of-phase).

e.g. each left and right speakers need to be checked by playing back another recorded file ([url removed, login to view] or [url removed, login to view]).

- finally, need to check the performance of the speakers by using pink noise.

e.g. each left and right speakers need to play a specific pink noise ([url removed, login to view]). Then we check a few important frequency band (maybe for this case, we do NOT have to use the full 31 bands). We will most likely to use 6-10 bands to detect the performance, e.g. 80Hz, 250Hz, 1000Hz, 2000Hz, 4000Hz & 10kHz.

The software will perform step-by-step check and will report if the speakers are NOT functioning properly.

The flow should be:

1. Test number 1 (Speaker Balance Check), when a left or right speaker is broken, a light will flash showing which speaker is broken. then it should NOT proceed to the next test.

2. Test number 2 (Polarity Check), when a left or right speaker is out of phase, a light will flash showing which speaker is broken. then it should NOT proceed to the next test.

3. Test number 3 (Frequency Response Check), when done analyzing the frequency response of both speakers, please show the 1/3 octave level representation of each chosen frequency.

That's about it.

Please note that a normal PC microphone is used for this test.
