An analgesic for high-performance audio on the iPhone, iPad and Mac OS X.
Really fast audio in iOS and Mac OS X using Audio Units is hard, and will leave you scarred and bloody. What used to take days can now be done with just a few lines of code.
Novocaine *audioManager = [Novocaine audioManager];
[audioManager setInputBlock:^(float *newAudio, UInt32 numSamples, UInt32 numChannels) {
// Now you're getting audio from the microphone every 20 milliseconds or so. How's that for easy?
// Audio comes in interleaved, so,
// if numChannels = 2, newAudio[0] is channel 1, newAudio[1] is channel 2, newAudio[2] is channel 1, etc.
}];
Novocaine *audioManager = [Novocaine audioManager];
[audioManager setOutputBlock:^(float *audioToPlay, UInt32 numSamples, UInt32 numChannels) {
// All you have to do is put your audio into "audioToPlay".
}];
Yep. Novocaine is result of three years of work on the audio engine of Octave, Fourier and oScope, a powerful suite of audio analysis apps.
