Hi! I know some self-taught c++ and i want to dive into digital sound processing, but I lack even the most basic thing - sound output.
How can I take a set of samples and output it on the sound card? I don't want to do it with a wav file, but actually with a bunch of values I have generated.
I've tried googling, but I haven't found too much useful stuff.
Thanks
Is this on a Windows system? Try the "directsound" API, perhaps?

Yes, it's a windows box.
Meh. isn't there a way without involving directX?
using a low-latency ASIO mixer, perhaps?
DSP usually means a digital signal processor, which is sometimes found on sound cards. which one do you want to know?
i knew that it means processing, but i guess that it can mean both.
I want to know how to output chunks of values on the soundcard so i can hear them :)
I wouldn't know - of course, you could always try opening the soundcard itself and send IRP's directly, but I'm not sure that's a particularly good way to do it. Have you had a look at what the DirectSound API contains? [I had a very brief look, and it seems like you need a WAV format, but then I suspect you can't just give some arbitrary samples to the sound driver anyways, so you will most likely end up with a WAV or similar format - but you shouldn't need to write it to a file].

I'll check. Thanks!
Well, a WAV file contains a pretty long list of samples. My point was that I don't want to open the WAV, and send it via two commands, I actually want to generate the samples and send them out to the sound card.
