[BUG] in Record Count Down; + Quirk & Questions

[dreammachine_nl]

Bug (Mulab 8.5.4 32-bit demo version):
Record button -> right click 'Edit Record Setup' -> Property 'Count Down': when set to zero the recording doesn't start immediately. In demo version 7.7.4 it works fine.

Quirk: Open an audio stream in the audiolab editor (this can only be done via the compose area, right? No option to show the stream undocked/windowed; for example via the Mulab Browser) and zoom in to extreme levels. At a certain point a kind of visual cutoff (much like a windowing function for FFT) appears, only on the right side of the editor (see also picture below, in the red circle). Opening an audio sample in the audiolab editor and zooming in extremely doesn't show this behaviour.

Question 1: Zooming in in the audiolab editor always happens at a sample zero-crossing; is there any specific reason for this? Like this, it is never possible to zoom in on a peak without horizontal scrolling. Or when a sample starts/ends at any non zero value, it also not possible to zoom in on the start/end without horizontal scrolling. Not a big deal, but I was just wondering.

Question 2 (or maybe FR): While doing some testing with looping stereo samples, I wondered how a stereo wavefile was graphically presented in the audiolab editor. I found out it is not a summed (or mono) version of the two channels (like the Oscilloscope module presents it), but it's a graphic overlay. To illustrate this I imported a stereo wave file with a sine wave on one channel and an inverted sine wave on the other. Mulab's audiolab shows the file like this (ignore the red circle this time ):

Am I correct? I only found one other thread on this topic, and it was said that showing stereo samples on separate channels is on the wishlist, but I was wondering if an inbetween solution could easily be implemented, for instance coloring the two channels separately in the audiolab editor? Maybe with adjustable color transparency, like the stereo view in the Frequency Spectrum Analyser module. Or better, implementing the dropdown menu 'mono mix, stereo, left, right' from the Freq Analyser as well.

Thanks again for the reply, TDM.

Will be fixed in the next update. Thx for reporting this.

Quirk: Open an audio stream in the audiolab editor (this can only be done via the compose area, right? No option to show the stream undocked/windowed;

When you have selected an audio stream part in the composer, right-click the Edit button at the top to open it in a floating window. You can also Shift+doubleclick the part to open its editor as a floating window.

Please email me a full size screen shot of this.

In the next update this has been finetuned so zooming in the audio editor will be pure on the mouse cursor point.

Excellent, thank you and an email has been sent.
