capture audio from mic input

``c++ ofxAudioCapture audioCapture;

// list all audio devices AudioCapture::printDeviceList();

// get a ofSoundStream device (using MS DirectSound API) ofSoundStream soundStream; auto devices = soundStream.getDeviceList( ofSoundDevice::Api::MS_DS );

// setup to capture from ofSoundStream / mic input:

ofSoundStreamSettings soundSettings; soundSettings.setInDevice( devices[0] ); // use specific audio device soundSettings.sampleRate = 48000; // hz, also 44100 is common soundSettings.numOutputChannels = 0; // no output, just input soundSettings.numInputChannels = 1; // one channel input soundSettings.bufferSize = 512; // ? seems to work soundSettings.numBuffers = 4; // ^

int bitsPerSample = 16; // bits per sample of audio writer, also 24 is common

audioCapture.setupAudioInputRecorder( soundSettings, bitsPerSample );

// begin capturing auto path = ofToDataPath( "audio_capture.wav", true ); // absolute path audioCapture.beginRecording( path );

// ... mic input is automatically piped to the audio capture writer ...

// later - end capture audioCapture.endRecording();

// now WAV is saved to bin/data/audio_capture.wav

capture audio manually

c++ ofxAudioCapture audioCapture;

int numInputChannels = 1; // number of channels int sampleRate = 48000; // Hz sample rate (e.g. 44100) int bitsPerSample = 16; // bits per sample of audio writer (e.g. 24)

audioCapture.setupManualRecorder( numInputChannels, sampleRate, bitsPerSample ); std::vector<float> buffer;

// begin capturing auto path = ofToDataPath( "audio_capture.wav", true ); // absolute path audioCapture.beginRecording( path );

// fill buffer... // add audio frames... audioCapture.audioIn( buffer.data(), buffer.size() );

// later - end capture audioCapture.endRecording();

// now WAV is saved to bin/data/audio_capture.wav ``
