Re: [SoX-users] fun with sox - barefoot mp3 streaming

[D. S. <new...@gm...>]

Now that i have sox 14, streaming from a .pls url using sox->play
works great. This will be nice for talk shows too; I use compand
0.1,0.3 -60,-60,-30,-15,-20,-12,-4,-8,-2,-7 to give audio a consistent
high volume. (I hate it when one talk show speaker is too loud,
another too soft.)  Now I can more easily use it for streaming,

I did have a little "play" -related snag in Cygwin where I use -t
ossdsp /dev/dsp to play to the soundcard, but, I also have libao
installed. In sox.c, I needed to make set_device() not attempt using
ao for the play device (I have libao, so not sure why that was a
problem).

Before I got:

$ ./play monkey.wav
./play ao: Could not find a default driver
./play soxio: Can't open output file `default':

So, as a work-around for cygwin (which has ossdsp*) I changed
set_device to not use ao in Cygwin.(sox.c:373)

 371 static void set_device(file_t f, sox_bool recording UNUSED)
 372 {
 373 #if defined(HAVE_LIBAO) && !defined(__CYGWIN__)
 374   if (!recording) {

So now it uses -t ossdsp /dev/dsp for the v14.0.1 sox play, and works fine.

(* Cygwin OSSDSP hint: I had to copy over /usr/include/sys/soundcard.h
 and /usr/include/machine/soundcard.h headers from a linux system to
the Cygwin  system before I could get -t ossdsp /dev/dsp to work in
sox.)
