There will be available: - MME - Windows Direct Sound - Wasapi - WDM kernel streaming The feature request does nevertheless also apply to other operating systems. One can set different options in Preferences --> Recording...

The said plug-in does of course a lot more than just analysing a stereo track. It is in fact the most versatile of its kind--which easily overwhelms some users. Its main purpose is to regard a simple stereo track as made up of 3 channels, namely Left, Center and Right. Let's say you have a stereo tr...

That's better.

The deepest pitch on an Hammond organ is nominal ~8 Hz. In contrast to church organs, those deep basses are actually square waves in order to be audible, i.e. they include some upper partials. In any case, the deeper the frequency is, the greater the needed resonator body must be--exponentially--up ...

If somebody asks you a question and you shake your head no, that's what it would sound like.

A beautiful analogy, Koz.
It is one of the frequencies you have to feel in your belly, rather than to hear it (Bellyphones?

).

(referring to the C code example) The pitch detection is the difficult part within this scheme. We have very low frequencies and therefore a high integration time. This means that a tracking algorithm needs 882 samples to detect a 50 Hz cycle. Nyquist has a built-in function to find a fundamental fr...

What do you mean by launched? As an example, if you open the Windows Command Prompt, the prompt will indicate the current directory. If you then launch Audacity from the Command Prompt, *default-sf-dir* will indicate the same directory as was shown in the Command Prompt. If you then close Audacity,...

How about (print *default-sf-dir*) No that's not reliable. It seems to show the location from which it was launched rather than where the executable is. What do you mean by launched? I launch it via link on the desktop, but it returns the right directory. Another way but probably giving the same re...

Thanks folks, I've accidently confused the function order. For FM it wouldn't even be audible--just half a Hertz off...

How about
