sinus wav file creation

sinus wav

anyone an idea on howto write a function that creates a wav file where the users can select the frequency? thanks

I don't want to use any library I want to create an easy example.

sinus.wav

I believe you can do it by changing the sample rate on the header of the wav file. It should speed up or slow down the "music".


Hope it helps.

sinus beep & music

If i understand good you need program wich produce sinus wav sound.
If is this you dont need function you only need API call Beep.

here is example in Creative basic:

DECLARE "kernel32",Beep(dwFreq:INT,dwDuration:INT),INT

and you call them with simple:

Beep(1600,100)

wich means 1600 Hz with 1 second duration.

If you wish complet program i will made one.
