signals

inguz audio
out comes music

Transparent digital EQ and room correction system for the (discontinued) Logitech Transporter® & Squeezebox™ wireless network music players.

DSP processing pipeline (C#) and SqueezeCenter plugin (perl, HTML). Open source software (MIT license)

One day, I bet Daniel that my (cheap and partly hand-made) stereo could sound as good as his (expensive hand-picked components), with a little signal processing.

Resolving this took a few years' learning, a gapless DSP convolution engine, a very smooth filter generator, transfer function measurement with exponential sweeps, resamplers, acoustic room treatment, compression drivers with directivity control, dipole bass, and all that.

I think we both won.

Open baffle loudspeakers are amazing, by the way.

Magical-sounding dipole bass and compression driver with CD horn

noise

halfbricking
live and direct

Field and location recording.

For ambience, I like the Core Sound TetraMic Ambisonic surround microphone.

Surround sound is enveloping and fascinating. As well as field recording, field playback is fun too.

Also, hanging out in bars or in the countryside with a microphone.

social media

"Pushbutton radio frequency identification tag for media content delivery", US patent 8755919.

I wrote this up for a ThinkWeek. The idea is nice and simple:

Digital media (movies, music, etc.) should be distributed on paper. Paper with a pushbutton: "play".

We spend most of our time in a physically social environment.
That's almost the definition of "quality time".

The affordances of phsyical things
structure the ways we play with them together.

There aren't enough good design patterns for this.

sync

"Synchronization and collaboration within peer-to-peer and client/server environments", US patent 8010487.

Practical methods for integrating centralized and masterless databases, client-server and peer synchronization. Co-authored with several others in the Groove team.

Mixes of central and distributed data will probably be very common in the future.

This patent reads like a "kitchen sync", it contains a lot of stuff.

Many strong ideas and practical techniques to deal with
