ofSoundStreamclass

Gives access to audio input and output devices.

ofSoundStream controls access to your computer's audio input and output devices. For example, you could use an ofSoundStream to get live input from a microphone, or generate sound in realtime for your computer's speakers.

A typical openFrameworks app will use just one ofSoundStream, and you might not even need to use this class directly at all if you don't need to query things like the sample rate or buffer size. In order to start receiving or generating audio, your ofApp should implement either ofBaseApp::audioIn() or ofBaseApp::audioOut() respectively, and then call ofSoundStreamSetup(). You can find examples of this in either the audioInputExample or the audioOutputExample.

Starting a stream with 0 input or output channels will prevent audioIn() or audioOut() from being called, respectively.

Some platforms (iOS, for example) will expose additional platform-specific sound stream functionality. See the platform-specific examples for demos.

Warning: Be aware that audioIn() and audioOut() will be called on a different thread from your app's update() / draw() thread.

nOutputChannels	number of requested output channels (i.e. 2 for stereo).
nInputChannels	number of requested input channels.
appPtr	pointer to the app which will own the sound stream (optional).

nOutputChannels	number of requested output channels (i.e. 2 for stereo).
nInputChannels	number of requested input channels.
sampleRate	requested sample rate (44100 is typical).
bufferSize	requested buffer size (256 is typical). Smaller values will be more responsive, but less stable.
nBuffers	number of buffers to queue. Less buffers will be more responsive, but less stable.
