Re: HELP!!! read/write WAV files for pitch shifting

Hi,

i'm currently working on this project which involves reading a wave
file, converting the data into a range of [-1,+1), then using STFT to
dopitchshifting, then play thepitch-shiftedwavfile. I have
already found information on STFT but it requires .wavbeing read intointegerarrays, then FT it into another array. Where can i find source
codes or examples on reading, writing and playing wave files fromintegerarrays? I've done some research, it seems that most people are
suggesting two ways:
1. DirectX SDK consists of examples of CSound CWaveFiles...etc. that
reads and play wave files, but how does it do that? the tutorials are
very complicated and i am currently using DirectMIDI to play
instrument sounds in my project(another part of the project other than
thewav) so I dont want to import all the DirectMusic files again
2. using mmioXXX functions seems to be another solution but again is
there any examples? Ive looked at the MSDN website, but im not really
sure wat to, how to and when to use the mmoiOpen,Read, Write...etc.
functions, how does this related to theintegerarraysthat i need for
my project? some people also mentioned about the MSDN LOWPASS sample,
but where can u find it online?
So which one of these two method is better? or is there another way?
actually the only thing i need is something similar to the miniAIFF
library onhttp://www.dspdimension.com/index.html?miniaiff.html
but this library only read AIFF files, is there a similarWAVlibrary?

Thanks very much

oopss....forgot, im working on VC++, so sample codes in VC++ would be
helpful
