Hi, I am fairly new to the sound processing and some stuff bugs me, if you have answer to my following questions please help me with them. - I have PCM data in the 16bit format, therefore I need to convert them to float and then apply some algorithms on them. The float conversion means that I each 4 bytes of the pcm will be converted to 1 float number - Now that I have the float numbers, what exactly these float numbers represent? I think they are the real part of the whole sound wave, is that right? - This float numbers, are they the the y axis of the sound graph or the byte numbers are the y axis of the graph? Please help with this questions, any one of them that you know can shed lights on my doubts.
