3rd Party Plugins - (fb2k) / Re: foo_truepeak True Peak Scanner
Last post by Defender -Sorry for copy-paste of my post from DR Meter topic but it is related.
@Case, would it be possible to add all features of DR Meter (per-channel DR, RMS and peak) to True Peak Scanner? The output log placed in the folder with actual audio files (as in old component) would also be very much appreciated (I would love to see every measurement in it, including LRA, Clippings and Peakstamps).
How does this plugin behave with files containing several streams (like bluray m2ts with more than one version of the album - ex. stereo, instrumental, DTS, AC3, THD...)? Will it measure the first stream (or which one?) or is it possible to measure all streams (changing the stream with stream-selector and measure them all one by one and getting different results not owerwriting the previous ones)? And if it is possible, how to write such tags with your external tags? In case of SACD-iso we can write an xml containing two sets of tags/measurement (one for stereo and one for 5.1) (I know that those are different, not two streams but separate sets of "audio files").
I have noticed that your component measures slightly different than buil-it RG scanner concerning True Peaks and Gain. I know that True Peaks are just (gu)esstimation of what would happen in the DAC but tried to manipulate the options in both components and never got exact the same measurements. My RG sacnner always was an 8xupsampling but I tried it with other options (SOX, SRC, 4x..) and yours with 190k and 384k. The results were always slightly different (rarely the differences were quite big, on some mp3 and the differences go both ways - sometimes yours shows less and sometimes more). Why is it so and is there a way to make them as similar as possible?
Of course results are different. With RG you can only use a fixed truepeak method. In other words it does not base the amount of upsampling on the content.
The truepeakscanner upsamples based on the content (up to a minimum of 192k if I remember correctly).
So the used upsampling methods differ, therefore also the results.
I don't exactly understand why this tool should give the exact information as the original DR component which is ancient.
Why not use the exact info from the scan resultscreen? Everything including LRA is there.
Only thing that could be better is to remove all Album stuff from the tracklines and show this info (preferably on top) as a separate line.
And it would be nice if tracknumbers&length would be included in the grid (eg total tracks/ total time for the album line).
