[igt-dev] [PATCH i-g-t v2 0/3] Check for audio noise and pops

[igt-dev] [PATCH i-g-t v2 0/3] Check for audio noise and pops

[Simon Ser]

This series is a continuation of "Add igt_audio self-tests and check for
noise/pops". Comments have been addressed on the last two patches of that
series, and a new commit adds a new phaseshift test.

In my real-world tests the power for these low frequencies go up to 0.0001 for
DisplayPort. In the self-tests a 0.0005 threshold detects a phaseshift of at
least 4 samples. Lowering the threshold to 0.0002 isn't enough to detect
phaseshifts with a lower number of samples. Thus I still think a 0.0005
threshold is reasonable.

The phaseshift self-test truncates 8 samples, just so that we have some freedom
if we want to change audio_signal_detect's logic. 8 samples is definitely a
very small phaseshift.

[igt-dev] [PATCH i-g-t v2 1/3] lib/igt_audio: detect noise and pops

[Simon Ser]

First, normalize the bin power by dividing it by the number of input samples.
We need to multiply by 2 since we get half as many bins as input samples.

Second, check that low frequencies are under a given threshold. If there is a
pop or some noise, the low frequencies will be affected.

I would prefer you repeating/holding the sample for multiple samples as
opposed to forcing 0.9.

How about naming the test "test_signal_detect_held_sample"?
