DirectSound-Buffer manipulating

An good idea for the next pure basic would be ,DirectSound-Buffer manipulating commands.

indeed, I want some sound buffers!
Maybe something like this:
LoadSound(#Sound, FileName$ [, Buffers])

I mean new commands to manipulate the soundbuffer directly.

Example:

result.l = GetInputSignal (mixer.l)
result.l = SetBaseFrequency (Sound.l); in percent
result.l = SetMiddleFrequency (Sound.l); in percent
result.l = SetHighFrequency (Sound.l); in percent

Sorry, what are these commands supposed to do?

Just an example,of course ...

result.l = GetInputSignal (mixer.l) ; Get the actual samplevolume( For effekts like spectrum-analyzers)
result.l = SetBaseFrequency (Sound.l,percent.l); Set the base-frequency of your sound(for equalizers)
SetMiddleFrequency ,SetHighFrequency for nearly the same.But for the other frequency-spectrums.

IsSoundPlaying(#Sound) and OGG Stream would be more important.

Hroudtwolf>you can't do a spectrum analyzer only with the sound volume value, you ll have to FFT the signal and the fonction will then return you an array of linear (or not) values of the signal.
I don't understand the SetBaseFrequency function ?
For the Middle, High, Low frequencies, you can write a biquad filter or, better, a FIR filter with windowing or remez polynominal interpretation.
Remember that the LoadSound PB function return you a DIRECTSOUNDBUFFER(8 ?) pointer.
