I have a montage, and I would like to examine in glance the correlation graph, as a curve, over the multiple waves display.
This would be much easier and quicker than listenting to entire album and checking the phasescope during the music.
I could not find a way to achieve this so far. I thought the analysis tool would be able to do this, but it’s only about different kinds of loudnesses.
How can I examine visually this correlation graph, maybe like with loudness, with different time scope (local means etc) ?
This is a feature I wanted to implement in the visual analysis tool of WaveLab, but I had no time, unfortunately. This will probably happen in the future.
There is, however, something you could do which can be useful. You open a given wave into the audio editor. Then you select the analysis mode “edit cursor”.
Then you click and drag the mouse cursor over the time ruler, left and right, and you watch the phase scope meter.
This is not what you are requesting, but it is a way to quickly check the correlation over an audio file. I mean faster than playing it in real time from start to end.
Many thanks fo the workaround. It works, but I ended up writing my own tool to scan a wav file, and output graphes (with gnuplot), for instance one for a given window (I use 0.3s-0.7s), with a histogram ([1,-1] divided in bins) and a few statistical key values (like mean and worst P5). It’s useful to evaluate many recordings through time and finalise a meaningful simple value. Here an example (piano recording), without histogram.
