In the DefaultOutputTest in the SDK there's a simple example of using an AudioConverter directly I think

Hi,
I must convert some audio data. I am on page 50-51 of the CoreAudio pdf. I am not sure I understand the process of the AudioConverterRef. I understand that I set up a converter instance with two AudioStreamBasicDescriptions, in and out. However, on the AudioConverterFillComplexBuffer(converter, inputProcPtr, userData, &ioOutputDataPacketSize, &bufferList, NULL) I don't understand how the &bufferList is working. Am I to create an instance of an AudioBufferList and fill in the mBuffers[i]->mData with the data I need converted? Also, the userData, must I set up constants that define what the new fields of the mData will be set to in the inputProc function (like on page 51)?
Or, is there any further documentation, or examples of a working AudioConverterRef out there?
