Tips

• The 3 dB tolerances are adjustable to be tighter or looser depending on the

requirements and what needs to be proved.

• The purpose of the /tmp/autodred.dat file is that it provides easier viewing of

all the data. The same signal levels are shown in the component data viewer.

Distance above noise floor is only shown in the file.

• The background noise test (test 5) can be useful, but it should only fail if

there is a drastic change in background noise level. In the Mathplan tables

for levels and thresholds, the background noise test is the first entry in the

“5” column. To start, set a larger threshold, perhaps 6 dB.

This TableXY should be populated with the measured RMS signal level for each

speaker, for each test. These levels should be copied from the /tmp/autodred.dat file

following a setup run.

Enter failure thresholds (in dB) into this TableXY for each speaker, for each test.

The AutoDRED test will fail if one of the measured signal levels differs from the

reference levels by more than the specified failure threshold.
