General - (fb2k) / Re: Binary Comparator version 2.0
Last post by dumbbird -
hey there, thanks for the awesome audio comparator taking gap offsets into account. I find it quite useful when i need to compare two audio tracks with different gap offsets - this tool helps to eliminate the difference caused from gap offsets and compare the actual audio.

now, on top of this, im not sure if this tool can be developed into something smarter, to be capable of doing things like:

1. when comparing two audios with different levels of track gain, to eliminate the difference caused by the gain levels and only to compare the real contents of the audio works? Or in other words, given two sets of audio tracks with different gain levels, first step to unify the gain levels, then do the comparison?

2. when comparing two audios with different play speed, to eliminate the difference caused by speed variances and compare the real contents?

I am not sure how valid and how niche these are. It's likely that we are not supposed to rely on binary comparison tools to make such comparisons. and instead, we should make use of more professional audio tools like Adobe Audition etc. to do so.
However, just wondering if there is any tools or methods that are as efficient to use as this binary comparator tool - without having to manually align the offsets/alter the gain levels/unify the play speed in professional audio tools; and be able to return a readable summary of comparison results like what binary comparator tool does.

Thanks for any thoughts/insights in advance!

Using (old version) ffmpeg of cli tool for performance comparison is flawed and extremely biased.
Also current ffmpeg cli tool have bad performance with smaller packets due to clumsy MT work of ex-developer.
Also just to run generic build of ffmpeg for the first time takes extra time... That is just few points I wanted to emphasize how such comparison is unfair and biased.

@Case sorry to bother you again but could you please consider implementing PLR in your scanner. Recently you have incorporated LUFS so now PLR is the last thing we have to calculate with enormously long formula and it does not go to tags.
Thank you for this (and many other) great component.

Hey, it's all good! We now have DR built into Foobar natively, with this component (and the True Peak Scanner), so can use what we need. It's brilliant for mastering as I can get an instant readout of many different variables, track to track. Well done Cae. Does the True Peak Scanner now make this DR component redundant?

MAAT Digital obtained the rights to the DR intellectual property from Pleasaurize and immediately issued the plug-in meter as well as the off line stats generator.  LUFS may be standard, but it fails to accurately represent some genres of music, which is why DR is useful.

Yup! We are the guys who created the PMF back in the day. I was a board member along with Karl Maria Brandenburg, and my MAAT co–founder Friedemann Tischmeyer was the PMF’s creator. Friedemann is a member of the ploud group that formulated 1770. We designed and launched the DRi standard to provide an easy to understand and repeatable measurement method to represent the perceived loudness of pop music.
