I was hoping somebody could help me out with a quick question are there any functions available to delete sample values from a data chunk in a wave file. I'm not sure you can do this with mmioread or mmiowrite. I was hoping to edit the values inside the data chunk a wave file. I can read and display the sample values but can you use mmiowrite to write over these values or would there be a better/easier way to go about it, any advice is greatly appreciated
