What would be the right way? about novocaine HOT 8 CLOSED

NSData is not the best storage format for live audio, but you might consult this post: http://stackoverflow.com/questions/4859760/obj-c-how-to-convert-nsdata-to-an-array-of-ints

If you're performance limited, I'd suggest unloading all the audio ahead of time into an array, and reading through it when it's time to play it.

The guide says "All you have to do is put your audio into "audioToPlay". What would be the appropriate way to do it? I have a NSData with the audio.

Thank you very much!

My audio is coming from an udp socket, so I didn't have many options I guess(as far as my limited knowledge goes)

Thanks for the link, I am going to try it out!

Sorry for bothering, hopefully it is trivial enough so you can help me.

I got my array of ints from my NSData. But can't put it into audioToPlay

for (int i = 0; i < numFrames * thisNumChannels; i++) {
     audioToPlay[i] = ?
}

Thank you once again!

If your data is a single channel, then

for (int i=0; i < numFrames) {
for (int iChannel=0; i < numChannels) {

audioToPlay[i*iChannel] = audio_array[i]

}
}

But it will definitely depend on the format of your audio.

As a future reference, these types of question depend more on managing C
arrays, and wrangling NSData from Objective-C, and I think you'll find much
quicker and more in-depth answers at StackOverflow.

I had a question on this and i have already posted it here. But nobody is replying me.

Would you please take a look at this question ? >> #61

@partho-maple, this question is more suited for StackOverflow, since it is not a bug in Novocaine, but a more general programming question. If you tag the question with "novocaine" and "obj-c" and "ios", many more users will be able to see the question and help you there, since not many people watch the issues here.

@alexbw I have already posted it on Stackoverflow about 14 days ago from now but nobody had replied that. This is the link >> http://stackoverflow.com/questions/19212699/how-to-change-input-and-output-audio-settings-of-novocaine-project

WOuld you like to take a look and answer it ?
