ofxAddons
openFrameworks addon to render vector<float> data by uploading frames to FBO textures.
Forks
Forks pushed to more recently than paulreimer/ofxRingBufferTexture itself, plus any admin-confirmed fork with commits of its own — worth checking if you're hitting issues with the original.

How to use in an openFrameworks app
testApp.h
``c++ include "ofxRingBufferTexture.h"
class testApp : public ofBaseApp { public:
void setup(); void draw(); void audioIn(float input, int bufferSize, int nChannels);
ofxRingBufferTexture spectrogram; }; `
testApp.cpp
`c++ //-------------------------------------------------------------- void testApp::audioIn(float input, int bufferSize, int nChannels) { for (size_t i=0; i<bufferSize; ++i) audioChannel.inputBuffer[i] = input[i];
audioChannel.process(); spectrogram.addFrame(audioChannel.spectrum); }
//-------------------------------------------------------------- void testApp::draw() { spectrogram.uploadToTexture(); spectrogram.getTextureReference().draw(windowRect); } ``
