How severely does this bug affect you?:
Steps causing the bug to occur:
Hi I hope this is useful. I'm unsure whether this is a bug or a known limitation of the node. But here goes...
The "calculate amplitude for frequencies" sends data that doesn't match well the information received by other software frequency analysers. In particular the lowest bins appear much too loud. I've tried using exponential, logarhythmic scales etc etc on the x-axis but the best I can acheive is still well off what I see on other software.
Have you found a workaround?:
A workaround is to apply subsquent maths nodes to compensate.
Please see the pictures below. The first is a fairly basic plotting of the data from the calculate frequencies node. The Frequency Bin Averaging is set to none and the X-axis is exponential. This is about as good as I can make it look. The second picture is a free software analyser VST from voxengo. Both analysers are receiving the same pink noise audio.
