Direct Sound problem (DirectX)

Zombrex · 2004-01-14 00:41:54

I have been trying to write a program with Direct Sound (part of DirectX) that will play two pure tones together (sine waves at 1000Hz and 700Hz). Created the buffers and changed primary buffer to 16 bit 44100 samples, loading in two .wav files at the correct settings (16bit, 44100 sample rate again) Each tone plays fine…

I have been trying to write a program with Direct Sound (part of DirectX) that will play two pure tones together (sine waves at 1000Hz and 700Hz).

Created the buffers and changed primary buffer to 16 bit 44100 samples, loading in two .wav files at the correct settings (16bit, 44100 sample rate again)

Each tone plays fine when I play it on its own. The problem is the program is for a project that deals with 2 or more pure tones played at the same time, so I need both buffers to play at the same time.

When I play both buffers at the same time I get really garbled output from DirectSound. I have played the two tones in a sound player and they don't sound at all like what DS is producing when they are played together.

Anyone have any ideas.
