I can't... is only a square wave but i can't create this... a pcm format buffer with 2 constants intervals (and looping) doesn't create a perfect audio out whith a square wave... divergent pulses appear where de "jump" occurs... I say "divergent" because are bigger than amplitud of square wave (some …

I don't know much about audio processing; but that article suggests using a low-pass filter. "low-pass filter" is a electronic component.... I don't know how use this information in a program source code.... OpenAl, don't filter my wave....(no?)... ok... I think I'm undertand... I tried whit this: …

http://en.wikipedia.org/wiki/PC_speaker yes...but.... mmmm It's a square wave... but ... if you build a wav file with a perfect square wave, the sound card creates a ugly square wave (with pulses where the wave pass from positive to negative)... I must create a square wave with a bit smooth shape …

OK... I undestand,... I'm studying the OpenAl Library and I think i can build a wave like old pc-speakers... but I don´t know the shape of this wave, it's not a exactly square wave... do you know how the wave shape is? 😀 thanks

But I want use FreeBasic.... I dont know why SOUND and PLAY are not present in FreeBasic. If DosBox can emulate the soundspeaker, why FreeBasic can't generate the same sound (some type of square wave)???. FreeBasic needs a library that I think a DosBox developer know how create... Of course, if that …
