Aaron McLeran and Dan Reynolds joined us over Skype to talk about the new procedural audio features in Unreal Engine 4.16. Aaron began with an introduction to UE4’s visual scripting system, Blueprint, picking out topics such as execution order, data structures and messaging, and making useful comparisons to the way various features are implemented in MaxMSP.

After a demo video of his procedural music system, Dan Reynold’s opened up his Blueprint graphs for a deep dive into the logic flows controlling several pre-built synthesisers – each one engineered in Blueprint using data structures, and each running in real-time in the engine. Video of the presentation and Q&A is below!

Download Unreal Engine 4.16 here and start making stuff! We hope to run a UE4 procedural audio workshop + show and tell at PANow later in the year.

It was great to welcome Leonard Paul back to PANow, to give a presentation on his procedural music composition for the movie, ‘Beep: A Documentary History of Game Sound‘, a screening of which preceded his talk. Leonard gave us a run down of his work to date with Pure Data, and took us through some of the patches he created while working on the score; revealing the constituent parts and how they are put together, before diving in for some live performance.

Video of the presentation and Q&A is below.

We were very pleased to have procedural audio veteran and PANow regular, Paul Weir, speaking at the May meetup.

Paul has been involved in some groundbreaking generative music projects for games and retail spaces over the past 20 years, and he began his talk with an overview of his work to date – discussing the pros and cons of PA, some of the challenges you might meet, and how the technology has progressed over time. Following on from that we had a listen to audio examples of the works and took a look at some of the custom software used.

His work for retail spaces is often driven by the client’s need to stimulate a specific mood in the customer. Paul spoke about how he approaches each brief: weaving together location recording, sound design, system design, and finally on-site installation of the standalone music systems, in places as diverse as banks, airports, outdoor public spaces, and high-end department stores.

Video of the presentation and Q&A is below. (The video framing is off-centre for the first couple of minutes).

Paul Weir is an Audio Director, Composer and Sound Designer, currently working as an Audio Director with Microsoft and for Hello Games’ procedural sci-fi game, No Man’s Sky.

Anthony Prechtl was at April’s event to talk about his current research at the Open University. He is developing generative music software for games which uses run-time data to change a variety of musical features.

Anthony’s Unity demo, Escape Point, is a first person puzzle game in which the player wanders round a 3D maze also inhabited by an AI enemy. He demonstrated the game first without music, then with a static score, and finally with a dynamic score (see video below, far right). For the dynamic score, the intensity of the music increased as the distance between player and enemy decreased and among the musical features affected were: a distortion DSP affected the synth parts, harmony and chords transitioned to minor scales, tempo and volume seemed to increase, The net result gave a feeling of tension that ebbed and flowed in relation to distance from enemy…

Video of the presentation, and audio from the discussion that followed, can be found below.

It was a pleasure to welcome procedural audio pioneer, Leonard Paul, to February’s meetup! Leonard shared some of the highlights of his procedural audio career to date, and talked in depth about his early ambitions to develop tools for videogame integrations, using Pure Data to build prototypes that might one day emerge in a AAA title. He went on to discuss the current state of play, looking at the movers and shakers in the field and where they could be heading next, before leading us into a Q&A session and some open discussion.

During a demo of his music and SFX systems for the educational game, Sim Cell, he explained how he used oscillators, variable delay lines and granular synthesis patches in Pure Data to generate a dynamic soundtrack that could react to different game states, as well produce as the more routine sound effects used for GUI navigation and spacecraft propulsion.

Jorge Garcia is a PANow regular and we were very happy to have him at the front of the room for November’s meetup! His presentation looked at some of the current challenges and opportunities when implementing and controlling procedural audio models in games. He showed how the Open Sound Control (OSC) protocol can be used to establish communication between game engines and audio patching environments like Pure Data, and went on to discuss his own open source implementation of OSC for Unity3D. Since 2011 UnityOSC has been used to build dozens of community-driven prototypes, demos and projects, many of which can be seen in the slides below.

Heavy: A Procedural Audio Development Workflow: generating DSP code from Pure Data for integration into a Wwise/Unreal environment

Martin Roth, Joe White and Andy Farnell presented different aspects of their new procedural audio workflow, Heavy. Addressing many of the common concerns held by audio designers and programmers, they unveiled a workflow that can generate highly optimized C code from (but not limited to) Pure Data synthesis patches, and seemlessly implement them in a UE4 game environment as Wwise plugins.

You can watch a video of the presentation below!

Ignacio Pecino gave a demo of some recent research in procedural audio, and talked specifically about his use of spatial data in simulated physical systems such as cellular automata (‘Life’) to drive sonification models in SuperCollider.

In his Apollonian Gasket simulation, he takes data gathered from the motion of the component discs when they are made to spin like coins, and uses it to dynamically modify parameters in a SuperCollider synthDef.

Using flocking behaviour alogorithms in another simulation, ‘Boids’, he generates complex, evolving soundscapes that have a highly satisfying correlation to the movement of a flock of birds in a 3D virtual environment.

We look forward to more hearing sonifications on his next visit!
