Peter Brinkmann & Rich Eakin: Real-time audio synthesis with libpd

Interested in making creative audio/music/synth apps for iOS? Then this month's meetup is for you. Peter Brinkmann and Rich Eakin, two of the primary contributors to the libpd-for-ios project, will co-present "Real-time audio synthesis with libpd".

About the talk:
Pure Data (Pd) is a visual programming language for interactive computer music and more. libpd is a lightweight wrapper that turns Pd into an embeddable synthesis engine, letting developers deploy real-time synthesis code as easily as media files.

Peter and Rich will present a brief introduction to audio synthesis with Pd, an overview of the design and API of libpd, as well as a sample iPhone app that illustrates the interaction between Pd and Objective-C, with special emphasis on the workflow from prototype to production.

Presenter bios:
Peter Brinkmann (, @nettoyeurny) holds a PhD in mathematics and has published papers on group theory, topology, virtual reality, and computer music. He has contributed to several open source projects, was a college professor, and is now a software engineer at Google. His book on audio synthesis on mobile devices, "Making Musical Apps", was published by O'Reilly Media.

Rich Eakin (, @reakinator) studied music technology at U.C. San Diego and Universitat Pompeu Fabra, where he developed audio synthesizers and controllers for music performance. His interest in multitouch controllers led him to the iOS platform, whereafter, by day, he has developed production apps for businesses in Sydney and NYC. By night, he writes creative software with frameworks such as libpd and cinder, in hopes of contributing to a more interactive experience with art on digital devices.

Location details:
We'll be at Time Inc. this month. (Thanks Stacey!)

    Hi everyone, this is my first attendance of the ios meetup and I wanted to quickly introduce myself. I am iOS developer at night and IT Director at a healthcare company during the day. A month ago I released my first app in the App Store - please check it out http://iCorpApps/money
    If any one is interested in free copy send me an email and I will provide free promo code [masked]

    Hi everyone!

    Like Samantha, I made an announcement last night, and just wanted to reiterate that call out here:

    I am coordinating guest lecturers/ speakers for an Advanced Software Development program I am coordinating with CUNY. The students are learning Objective C, iOS, and will be working together on projects come 2nd Semester, so we want to supplement the basic class lectures with real world perspectives - the point is to deviate from strict academia and bring an influx of the practical knowledge that only working developers can relate in a mentor-like role.

    Email me at [masked] for more information, to join the fun, or for whatever else you can think of :)

    Hey guys. I'm a just-for-fun developer with tons of ideas (who hasn't?) but few collaborators. I'd enjoy to team up with someone and maybe work on something interesting. My work is here:
    I'd particularly like to update the music apps... (specially BluesMachine).
    If you're also not interested in becoming an "app star" and would like to discuss working on something on your your free time, feel free to contact me: cicconet at gmail dot com.

    A great set of presentations on pd and libpd on a totally new area for me, real-time audio.

    Could somebody post highlights? Had a hard time getting out of the office in time for check-in so I got turned away.

    Will the presentation be video taped?

    They're pretty serious over there. They hassled me for a pair of scissors in my bag and my colleague had to put his skateboard through the x-ray machine. They also checked my driver's license to answer your question.

    How strong is security? Do we need photo IDs or will a name tag on the left lapel suffice?
