It's surprising how few people have heard about the most flexible tone generator (=synth) out there: csound http://www.csounds.com The latest package has a Gentoo ebuild, too, which is not in the repository, however. You can do *everything* with it, and it's so fast you can use it as MIDI player, too. Regards ralf -- gentoo-user@lists.gentoo.org mailing list

One of my friends coded something like this once as a plug-in for
XMMS. Can't seem to find it now. Perhaps you'd have better luck than
I.
On the other hand, a little bit of C++ should be fairly easy. First
you need the 'play' program from sox. 'play' can play files in the
'raw' format, which is just a stream of words that gives the amplitude
of the waveform. For example
play -t raw -s l -f s -c 1 -r 3 -
takes as input stdin, plays mono channel sound from a stream that is
signed-linear, 30 hertz sample rate, and with amplitude described
by 32 bit long word. Next you just need a waveform generator. A C++
snipplet from something I cobbled together several years ago (yes yes,
my coding practice can stand much improvement, so sue me)
#include stdio.h
#include unistd.h
#include math.h
int main()
{
int rate = 3;
int coramp = 0xCEF;
int tempamp=0;
float totalamp=0;
int f_count;
while(1) for(f_count=0; f_count rate; f_count++)
{
totalamp=sinf( ((float)f_count) * 440 / rate * 2 * M_PI);
tempamp = (int) (coramp * totalamp);
printf(%c%c%c%c%c%c%c%c, (char) (tempamp), (char) (tempamp
8), (char) (tempamp 16), (char) (tempamp 24), (char) (tempamp), (char)
(tempamp 8), (char) (tempamp 16), (char) (tempamp 24));
}
return 0;
}
Yes, it is an infinite loop.
The sinf makes it a sine wave. You can code your own triangle wave.
THe 440 makes it output A-440. It is the frequency.
coramp is an amplifying factor.
compile it, run it like
./a.out | play -t raw -s l -f s -c 1 -r 3 -
And you should get A-440 out of your speakers.

The defaults of aplay is sampling it incorrectly, which is why the file sounds off. Now, I think I know what the problem is with sox: 1) the commandline syntax changed between 12.* and 14.0, the switches I need should be play -t raw -s -4 -c 1 -r 3 (c.f. man play). 2) Despite what the man pages say, the '-' switch for reading from stdin seems to be broken. Probably a bug. I'll test more and possibly file a bug report. On the other hand, since you have aplay installed, the right syntax should be ./a.out | aplay -t raw -f S32_LE -c 1 -r 3 Which says to use 32 bit little endian with 1 channel at a sample rate of 3.
