Making a big noise with Linux, again.

Walter Lapchynski will be presenting on doing audio with Linux.

Hopefully he won't get sick this time around.

    Thanks, everyone, for coming. I had a great time. I look forward to sharing Overture livecoding with you in the future! Slides are here: http://files.meetup.com/8125762/big%20linux%20noise.pdf

    Awesome. More than met my expectations. Glad to see such an enthusastic group of Linux users.

    I'm interested in the physical modeling synthesis as shown here: https://ccrma.stanford.edu/software/stk/index.html

    I have compiled some of the examples in Ubuntu.

    I eventually want to port some of these algorithms to an embedded platform.

      That's cool stuff. I haven't seen that before. Certainly appropriate on an embedded platform. Sound design is certainly possible in a million and one other possibilities— Pure Data for example (in fact, there's a book written on the subject that's really great). I'm not sure it's small enough for your application, but I've been working a lot with ChucK which, being written in C++, is very powerful. Unfortunately, it does use a virtual machine which might be a wee bit too much overhead, but it's super powerful. Have you seen Supercollider? It's also C based. I've also been working with Overture, which is a cross between Clojure (read: Lisp) and Supercollider. Clojure does use a virtual machine, though.

    I have my plans on what I'm going to do, but anyone else have any particular areas they're interested in? I could spend all day talking about the subject, honestly.

      I run a heavily tweaked Lubuntu. I've actually included kxstudio's repos in my sources.list. They serve up a low latency kernel. If you've got that, you're pretty much good to go. Depending on your system resources, there many be things to tweak about buffers and periods in JACK but that's about it. There's some additional group set up involved in rt, but there's not much to that. I have relatively limited experience with interfaces (most of my work is done virtually) but most of what I've done is pretty plug and play. Devil's in the details, of course.

      What I was really planning on doing needs a separate session so maybe this will be a little more introductory :)

    I want to play WAV files from a BASH script using Debian. I have struggled with this and I gave up. Goal is to play sound on motion detect.

      Not sure what sort of sensor you have, but given your experience with embedded applications/home automation I'm sure you got that figured out. I'm also guessing that since that's your application, you probably want to keep the footprint small. I've a bit less experience with OSS, but assuming Alsa's your sound server, you can just `play /path/to/your/file`.

I'm surprised by the level of growth I've seen since becoming an organizer, it's given me more confidence in my abilities.
