objective c - How to use an Audio Unit on the iPhone -

-

I see a way to change the pitch of the recorded audio as it is saved in disk or played back Goes real-time). I think audio units can be used for this. IPhone audio units provide limited support (for example, as far as I can tell) it is not possible to create / use custom audio units, but many out-of-the-box audio units are available, One of these is AUPitch.

How do I actually use an audio unit (especially AUPitch)? Are you hooking it somehow in an audio queue? Is it possible to combine chain audio units together (for example, simultaneous buzzing effects and changes in pitch)?

EDIT: After inspecting the iPhone SDK header (I think AudioUnit.h, I do not, at this time in front of a Mac), I noticed that AUPitch commented. So it does not seem that the Apache is available on the iPhone after all. Receipt RoA

Apple has better organized its iPhone SDK documentation in developer.apple.com - now to find references about it More difficult in Apich, etc.

He said, I still am interested in answering the quality when using the audio units (normally) on the iPhone.

Here are some great resources () to use the RemoteIO audio unit on the audio units on the iPhone In my experience of working with, I have found that I can implement a change manually in the callback function. In doing so, you feel that you can solve the problem.

-
Using Visual Studio 2005, if I open the test in VSMFI and try to run the tests, then sometimes the projects are ready. However, they run very slow. CPU 99% waste and output window VS Shows things associated with compiling it. Is there any way to fix this? It does not make any sense. It is not necessary to upgrade that we are a viable alternative to those people who have to deal with the legacy code. Did you try to upgrade SP1? I do not know of any specific problem in this area, but this will be the first change I tried to do.

I am trying to install Ubuntu on a USB, the problem is that I do not want to repeat the boot once, I want to keep my windows, but I want to boot Ubuntu using the virtualbox and USB to the Ubuntu Want to use my hard drive, but how? The virtualbox will not recognize USB as a hard drive when installing an ISO In virtualbox, you have to create a virtual hard disk. Make a USB drive and tell the virtual box to install a virtual hard drive that you just created. EDIT: To answer some more questions: In the new Virtual Disk dialog, click the button next to the location field, click on the button Virtual Disk on Flash Drive To access, click the arrow next to Save in the Select File in the window next to Save In, and you can access your flash drive from there.
