I’m working on a project using OpenAL and OpenGL, the latter I’m au fait
with but I’m new to audio programming and running into a bit of trouble.
To help me visualize any signal processing I’m doing I’m trying to
implement a crude oscilloscope with glPoint but I’m having a hard time
finding the amplitude of the waveform.
I’m loading a 16bit PCM wav with the following code:
alutLoadWAVFile("wavdata/Notify.wav", &format, &data, &size, &freq, &loop);
Now from my very limited knowledge of OpenAL and the PCM format, I was
lead to believe that ‘data’ should contain 16bit chunks of data
representing the waveform amplitude, but the access violations are
making me think otherwise.
Could anybody shed any light on this? I’ve been googling all night and I
can’t find anything of great use.
