Hi, I have read WAV files as data/numbers into MATLAB before for fourier analysis etc and am now trying to do the same with Excel. I have found code online which has allowed me to make use of the winmm.dll from windows to be able to create a WAV sound file from excel and also to be able to play them. Now i can record and play sounds i need to be able to read the data in the WAV files and perform Fourier analysis etc. Has anyone done this or have any code which i can implement to do this? Kind regards, Barrett.
