Im working on a project that manipulates Wav files such as being able to add an echo to it and so on. So far ive managed to read in the Wav, split it up into the header file and data and manipulate the data by adding an echo to it and flange type effect. However, I am struggling with volume. Id like to know how I can increase and decrease the volume of a Wav file. Ive googled around and found nothing that can help me so any help on where to start would be appreciated.
