Last post by pqyt -There's some confusion with the settings in v0.7.6.0. Peak is now right as you don't do any extra calculations to it.I just followed the article I quoted earlier. Like I said many times before: I'm not an audio engineer and don't understand this stuff half of the time. But when the specs are this confusing and 'people in the know' are debating definitions I prefer to stand by the sideline until the dust is cleared and a clear spec becomes available.
But RMS is incorrect. You always divide the real RMS value by 'Amax', which is the same as adding 3 dB to its value. Then in addition you offer an optional 3 dB addition to it.
Also the peak visualization bars go hidden here half the time (I have them moving horizontally from left to right). When I was playing stereo file, the right channel bar went invisible. I had to tweak the height of the UI element to make it visible. Then I played a mono file and now the size was incorrect for that size and it's invisible.It's a render bug caused by Direct2D or the driver. I thought I had solved it with the optimized calculations because I could no longer reproduce the bug here (after updating the GPU driver). It has to do with drawing the LED bitmap on odd coordinates. The filled rectangles don't have this problem, AFAIK.
I don't think the bars should go invisible under any circumstances.
