Making 2D Images from 360-degree Videos

For my annual Still Standing project, I am recording 360 videos with audio and sensor data while standing still for 10 minutes. I have started exploring how to visualize the sensor data best. Today, I am looking into visualization strategies for 360-degree images. I have written about how to pre-process 360-degree videos from Garmin VIRB and Ricoh Theta cameras previously. The Theta records in a dual fisheye format like this:...

2023, A Year of Still Standing

Yesterday, I completed my 365 Sound Actions project, during which I recorded one sound action per day as part of preparing for the launch of my book Sound Actions. Today, on 1 January 2023, I start this year’s project: recording myself standing still 10 minutes every day. You can follow the progress on Mastodon. Starting up AMBIENT Although I am happy about completing my sound actions project, I have enjoyed the ritual of doing something every day....

Starting up the AMBIENT project

Today, I am starting up my new research project AMBIENT: Bodily Entrainment to Audiovisual Rhythms. I have recruited a great team and today we will have our first meeting to discuss how to work together in the coming years. I will surely write much about this project on the blog. For now, here is a quick teaser to explain what it is all about:

Kayak motion analysis with video-based horizon leveling

Last year, I wrote about video-based motion analysis of kayaking. Those videos were recorded with a GoPro Hero 8 and I tested some of the video visualization methods of the Musical Gestures Toolbox for Python. This summer I am testing out some 360 cameras for my upcoming AMBIENT project. I thought I should take one of these, a GoPro Max, out for some kayaking in the Oslo fjord. Here are some impressions of the trip (and recording)....

Removing audio hum using a highpass filter in FFmpeg

Today, I recorded Sound Action 194 - Rolling Dice as part of my year-long sound action project. The idea has been to do as little processing as possible to the recordings. That is because I want to capture sounds and actions as naturally as possible. The recorded files will also serve as source material for both scientific and artistic explorations later. For that reason, I only trim the recordings non-destructively using FFmpeg....

Completing the MICRO project

I wrote up the final report on the project MICRO - Human Bodily Micromotion in Music Perception and Interaction before Christmas. Now I finally got around to wrapping up the project pages. With the touch of a button, the project’s web page now says “completed”. But even though the project is formally over, its results will live on. Aims and objectives The MICRO project sought to investigate the close relationships between musical sound and human bodily micromotion....

Recruiting for the AMBIENT project

I am happy to announce that I am recruiting for my new research project AMBIENT: Bodily Entrainment to Audiovisual Rhythms. The project will continue my line of research into the effects of sound and visuals on our bodies and minds and the creative use of such effects. Here is a short video in which I explain the motivation for the project: https://www.youtube.com/watch?v=7BFFfIydL5U Now hiring The idea is to put together a multidisciplinary team of three early career researchers experienced with one or more of the following methods: sound analysis, video analysis, interviews, questionnaires, motion capture, physiological sensing, statistics, signal processing, machine learning, interactive (sound/music) systems....
