This is my first post to linux-audio-dev, by the way, so hello everybody. :-)

Audio::* Perl modules. I like your Audio::Play module, it's the only Perl module I've been able to find that actually *works* for playing audio on Linux (Audio::DSP apparently has memory leaks, and Audio::OSS is just too complicated, and seriously lacking documentation). > Both have existing /dev/dsp style backends at present, which have been working > fine.

I cannot reproduce this on Suse 8.2 with an M-Audio Delta 66 card, but that card has other problems with the OSS emulation - I can only get it to play to ALL channels at once, which is kind of annoying when you have 6 out channels. > So I decided it was time to do a native ALSA backend(s). > I have rsynth backend working, and perl Audio:: one almost working. > But before going forward I would like to solicit opinions on what > is the "right" API to use. [ snip ] I might be biased because of my hardware setup, but I would really like a some ALSA (or maybe JACK) input/output modules with multi-channel support. I cannot really comment on the different drivers from a programming point of view, because I've only used them as a regular user, but some good, responsive multi-channel audio modules is just what I'm looking for. Then I could really put my LADSPA modules to some use :-) Joost. -- http://www.cpan.org/modules/by-authors/id/J/JD/JDIEPEN/
