Converting single bits into a sine waveform

[greenelephant]

Hi everyone


I am trying to create a program which reads 8 bits segments (1 byte segment) of an input file and converts that into a modulated audio sine wave that is outputted from the soundcard. The modulation is done in terms of amplitude, so a 1 bit has a high amplitude and a 0 bit has a smaller amplitude. I want to create a continuous sine wave whose length is directly proportionate to the amount of bytes in a selected input file

I have been given a sample code from a friend of mine which is attached. however I need the code edited to allow the following HEX values converted into sine wave


* 00 00 00 00 00 00 00 00 00 00 00 00 (represents break/separation between end of file and beginning of file)
* FF FF FF 22 22 22 (represents carrier wave to notify vb program the start of binary data represented by sine wave is due to commence)
* File binary data
* 22 22 22 FF FF FF end header (represents carrier wave to notify vb program the end of binary data represented by sine wave has occured)

I dont have the skill-set necessary to modify the original code given to me to suit my new proposal. Can anyone help me?

Thank you so much in advance for any help given
