I'm making a sound for the iPhone and I'm interested in adding background music and background sounds.
Is CoreAudio right for the job?
And if so, how do I use it?

I am writing a program in Objective-C (XCode 3.2, on Snow Leopard) that is capable of either selectively blocking certain sites for a duration or only allow certain sites (and thus block all others) for a duration. The reasoning behind this program is rather simple. I tend to get distracted when I…

Hi,
I made an Objective-C project for the iPhone. I had only one cpp class, the soundEngine taken from some Apple demo. Now I'm trying to merge OpenFeint which is coded in Objective-C++. As soon as I drop in the code without even referring to it from my code, when I hit Build, my Objective-C code…

Does anyone know of a way to add additional attribute types to the @property keyword without modifying the compiler? Or can anyone think of another way to genericize getter/setter creation?
Basically, I have a lot of cases in a recent project where it's handy for objects to lazily instantiate their…

I often display the same webpage, but with a different content. I would like to use a template HTML file, and then fill it with my diffent values.

@end

I am new to CoreAudio, and I would like to output a simple sine wave and square wave with a given frequency and amplitude through the speakers using CA. I don't want to use sound files as I want to synthesize the sound.
What do I need to do this? And can you give me an example or tutorial? Thanks.

I have been using Virtual DJ on my machine. The setup is where I want audio to play over the headphones and use a USB sound card to play audio into my headphones so I can listen to music before I play it for everybody.
However, the last time I tried, I got an error message saying "Error in the…

There are three major frameworks for iPhone audio :
AVFoundation Framework
CoreAudio Framework
OpenAL Library
And in turn CoreAudio Framework has
AudioToolkit Framework and
AudioUnit Framework
Is this correct?
Suppose I import AVFoundation Framework into my project and it in turn needs…

I am working on understanding Core Audio, or rather: Extended Audio File Services
Here, I want to use ExtAudioFileRead() to read some audio data from a file.
This works fine as long as I use one single huge buffer to store my audio data (that is, one AudioBuffer). As soon as I use more than one AudioBuffer…
