Beta-test: DeltaWave Null Comparison software

[pkane]

Hi.
Can Deltawave be set to only compare 2 files down til -40 db ?
As standard the Deltawave can find differences the human cant hear, so if it could be set to compare from highest peak and down to -40 would be nice

I'm not sure what you mean by 'compare til -40 db'. DeltaWave compares signals of all magnitudes, you can decide to look at or ignore any range that isn't important to you. On any of the charts, just zoom in on the range you want and exclude anything else.

@start means apply the filter before any matching/processing, @end means after all matching/corrections are completed. @start&end means apply both.

The @start / @end / both determines when the filter is applied to the waveform. @start is before any processing, as soon as the data is loaded from the file, @end is after all the corrections are done but before the final measurements are computed. @start/end applies the same filter at the beginning and at the end of processing.

I'm sure 24th and 37th page of this thread is perfectly fine place for this information, but could we get it also on https://deltaw.org

Unless I'm still confused about the meaning of those options, I think there is some bug in applying the filters in some combinations when both are enabled (DeltaWave v2.0.25).

With 100 HP@end, 8k LP@end or 100 HP@start, 8k LP@end I get band-pass, as I would expect:

With 100 HP@start/end, 8k LP@start/end or 100 HP@start, 8k LP@start or 100 HP@end, 8k LP@start I get band-reject :

With 100 HP@start/end, 8k LP@end it's even weirder:
