audio

A Google I/O 2013 talk by Android audio engineers on why reliable, low-latency audio is hard on the platform. It covers problem areas across the stack, platform work underway and techniques apps can use.

Timur Doumler's CppCon 2015 talk on how C++ is used in the audio industry. It covers the patterns and tools audio developers rely on, including handling real-time constraints.

An excerpt of the 2005 Harvard debate in which Steven Pinker gives his prepared case on biological sex differences and the under-representation of women in science. It covers cross-cultural patterns in preferences and abilities and the overlap between male and female distributions.

Chris Ford builds up from a single sine wave through layered abstractions to a Bach canon, using Clojure and the Overtone audio environment. The talk shows music theory as a natural fit for functional programming.

David Kriesel's 31C3 talk, in German, on the discovery that Xerox scanner-copiers silently replace digits and letters in scanned documents. He explains how the bug stayed unnoticed in the wild for years.

Mick Gordon's GDC 2017 session on composing the Doom (2016) soundtrack. He details his compositional process, production techniques and the experimental instrument and synth design behind the music.

K Lars Lohn's PyCon 2016 keynote weaves together music theory, programming, biking road trips and fractals. It is a personal, wide-ranging talk rather than a Python how-to.

David MacKay's 2007 Google Tech Talk presents Dasher, a text-entry system driven by continuous gestures and a language model, reaching about 35 words per minute with one finger and 25 hands-free. It explains the information-theory reasoning behind the design.

Bassist Victor Wooten argues that music should be learned the way children learn their first language: by immersion and play, without early correction or rigid academic instruction. He draws on how babies pick up speech from the people around them.

Adam Neely's Ableton Loop 2017 talk links rhythm, pitch and synaesthesia. He shows that polyrhythms sped up become chords, so tempo and pitch are related by ratios.

Andrew Sorensen's OSCON 2014 keynote in which he live-codes generative music on stage using his Impromptu environment while narrating his computational and musical choices. It imagines concert programmers as a performing art.

Sam Aaron, creator of Sonic Pi, gives a demo-heavy GOTO Chicago 2018 talk on live coding music. He covers the history of Sonic Pi, how it evolved, and what it can do for education and professional musicians.

David Kriesel's FrOSCon talk on how Xerox scancopiers, due to JBIG2 compression, silently replaced digits in scanned documents. He walks through how he discovered the bug and why it is so dangerous.

Edward Kmett's 2013 talk at Prezi in Budapest on succinct data structures, which store data in close to the information-theoretic minimum space while supporting fast queries. It ties together the research and walks through his Haskell succinct library.

Donald Knuth explains at Stanford's CCRMA the constraint-based methods he is using to compose a major work for pipe organ.

Ilya Sutskever gives a Simons Institute talk on why neural networks generalize, framing learning as finding short descriptions, like compression. It was part of the Large Language Models and Transformers program.

Andrew Ng presents unsupervised feature learning and deep learning, showing how algorithms can learn representations from unlabeled data instead of hand-designed features. He gives examples in vision and audio, including visualizations of features learned by successive layers.

Audio of Charlie Munger's 1995 Harvard speech on the psychology of human misjudgment, laying out a framework of cognitive biases and mental models for decision making. It covers factors like incentives, social proof and denial.

PS5 lead system architect Mark Cerny gives a deep dive into the PS5's architecture, covering its SSD, I/O, audio and design goals. He explains how removing bottlenecks shapes future games.

A clean-audio clip from Apple's 1997 WWDC where Steve Jobs answers a hostile question from a developer about OpenDoc. He argues you must start with the customer experience and work backwards to the technology.

Bret Copeland, in an astronaut costume, gives an energetic talk on how the Space Shuttle landed from orbit, including reentry and the unpowered glide. It includes real-time landing footage with HUD and audio.

Part 2 of the IROS 2011 keynote by Sebastian Thrun and Chris Urmson on Google's self-driving car. It shows how the car perceives its surroundings with a lidar point cloud and recognizes traffic lights and pedestrians. The audio is poor because it was recorded on a pocket camcorder.

A 2015 talk by David Deutsch with slides and audio about constructor theory and how physics, in particular the many-worlds interpretation, can be framed without probability.

A 95-minute recorded debate at the ARITH23 computer arithmetic conference between John Gustafson, proponent of unums/posits, and William Kahan, architect of IEEE 754 floating point. They argue the merits of the new number formats versus conventional floats and interval arithmetic.

Audio-only recording of the first part of John Carmack's QuakeCon 2010 keynote, taken from G4TV. It covers id Software's work around that time, including Rage and platform topics such as PC, PS3 and Xbox 360, and includes his informal audience poll about paying for mobile apps.

A London Haskell talk on the algebra of algebraic data types, showing how sum and product types behave like arithmetic. It frames types as numbers obeying algebraic laws.
