Convert WAV To BMP And Back
On RentaCoder one of the other coders thought I just wanted him to
change the extension from WAV to BMP. Another coder brought up the
complexities of actually converting WAVs to JPGs and back again,
because JPGs are compressed. And someone else asked me how they could
actually convert it. It is easiest if we work with BMPs and WAVs
because if we worked with BMP image files you just have to get into the
binary code of the file, and swap the headers around. So as long as
photoshop thinks the WAV is a BMP file you will be able to see what it
looks like and modify it. But I don't expect a graphical
representation that looks like a traditional wav file. I expect a 1
dimensional colorful psychedelic mess. I might have to add more
dimensions to the image, depending on the frequency of the samples in
the music. It just depends on how many colors I have to work with.
You might want to look into FFT (Fast-Fourier Transforms). They're the
standard way of generating waveforms from audio data. As others have
mentioned, I fail to see how Photoshop is going to make a decent front
end for your program.
Cheers,
