Research

Over the last year, I’ve been extensively researching an effect called clock drift in the multimedia domain. Clock drift is the deviation of a clock’s speed from the world time standard, resulting in shifts in sampling rates, and this shift leads to parallel recordings from different devices not being […]

The ITEC MediaPlayer library is a lightweight VideoView/MediaPlayer replacement for Android’s default components, enhancing it with exact frame seek, playback speed adjustment, GLES shader effects, picture zoom/pan by gestures, and DASH support. The source code and a more detailed description is now available on GitHub, its accompanying demo showcase app on the Google Play Store.

This is the accompanying website for the paper presented at MMM 2015, providing the download of the synchronization ground truth for the Jiku dataset.

Conducting high precision audio drift or audio frequency measurements doesn’t have to be expensive. In this guide, I’m showing you how to do it with an ordinary computer, an audio interface, a GPS receiver, and a bit of tinkering.

AudioAlign is a tool that I started developing in 2010 for my master’s thesis (and have been actively developing since then), with the goal to create a software for the automatic synchronization of audio and video recordings. Although I never quite reached the point of a fully automatic synchronization system, it showed promising results compared to the few similar commercial applications available on the market, and continues to be a helpful tool for my research purposes. I gave up on the plan to commercialize it due to patenting problems I didn’t know how to deal with, but instead decided on open sourcing it, so others can make use of it and hopefully even help me improve it.

Aurio is a library extracted from AudioAlign, providing the underlying core audio processing functionality, including audio fingerprinting and time warping algorithms. Both Aurio and AudioAlign are now available on GitHub under the AGPL license.

Protyposis Multimedia Solutions is the label under which I provide professional software development services in the multimedia domain.
