The ventilation system in my office

I’m sitting in my office, listening to the noisy ventilation system that inspired my AMBIENT project. Here is a short sample: At the moment, I am primarily focusing on completing my book Still Standing. However, as part of my year-long #StillStanding project, I have also started thinking about the sounds found in indoor environments. Asking ChatGPT for help I have yet to begin a proper literature review on ventilation noise, but as a start, I asked ChatGPT for help. We have had lots of discussions about what students can use ChatGPT for at the university this spring. The consensus is that it is a technology we cannot avoid and should embrace its possibilities and limitations. I have previously explored essay writing with You.com. To prepare myself for advising students on ChatGPT, I have decided to test it for various tasks. ...

Understanding the GoPro Max' File Formats

I use a GoPro Max 360-degree camera in my annual #StillStanding project. That means that I also have had an excellent chance to work with GoPro files and try to understand their inner logic. In this blog post, I will summarize some of my findings. What is recorded? Recording “a video” with a GoPro Max results in recording multiple files. For example, each of my daily 10-minute recordings ends up with something like this: ...

100 Days and Still Standing

Today marks the 100th day of my annual #StillStanding project. In this blog post, I summarize some of my experiences so far. Endurance Some people questioned whether I would be able to stand still every single day for an entire year. But, hey, it is only ten minutes (out of 1440) per day, and even though my life as a centre director is busy, it is always possible to find time for a standstill sometime during the day. ...

Sound vs Audio

What is the difference between sound and audio? I often hear people confuse the terms. Here are a couple of ways of thinking about the difference. A good summary can be found in this blog post: Sound is vibrations through materials Audio is the technology to hear sounds coming from natural or human-made sources Another good definition is that audio is electrical energy (active or potential) that represents sound. From this, a sound recording is stored as an audio file. It is important to note that we are not only talking about digital audio files. Audio can also be stored on an analog medium, such as an LP or cassette, from which it can be used to play back sound. ...

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. So I want to continue the tradition with a different project, and I have developed a concept that fits my current research interests. I am currently in the phase of starting up my AMBIENT project. The team is almost in place, and we have had many good initial discussions. ...

365 Sound Actions

1 January this year, I set out to record one sound action per day. The idea was to test out the action–sound theory from my book Sound Actions. One thing is writing about action–sound couplings and mappings, another is to see how the theory works with real-world examples. As I commented on after one month, the project has been both challenging and inspiring. Below I write about some of my experiences but first, here is the complete list: ...

Open Sourcing My Sound Actions Book

Last week, my book was published by the MIT Press, and I am happy to announce that the source code is available on GitHub. Most people are probably mainly interested in the content of the book. If so, you should grab a free copy of the final version. This blog post explains why I have made the source code available. License I was fortunate to secure funding from the University of Oslo to make the book freely available, what is often referred to as Open Access. Hopefully, this will be the norm in the future of academic publishing, but it is still a case-by-case decision for books. MIT Press published my book with a CC-BY-NC-ND license. I would have preferred a less restrictive license, such as the CC-BY-SA license, but that is how it is. ...

New Book: Sound Actions - Conceptualizing Musical Instruments

I am happy to announce that my book Sound Actions - Conceptualizing Musical Instruments is now published! I am also thrilled that this is an open access book, meaning that is free to download and read. You are, of course, also welcome to pick up a paper copy! Here is a quick video summary of the book’s content: In the book, I combine perspectives from embodied music cognition and interactive music technology. The approach is what I call “embodied music technology”. ...

Add fade-in and fade-out programmatically with FFmpeg

There is always a need to add fade-in and fade-out to audio tracks. Here is a way of doing it for a bunch of video files. It may come in handy with the audio normalization script I have shown previously. That script is based on continuously normalizing the audio, which may result in some noise in the beginning and end (because there is little/no sound in those parts, hence they are normalized more). ...

Video visualizations of mountain walking

After exploring some visualizations of kayaking, I was eager to see how a similar approach could work for walking. On a trip to the Norwegian mountains, specifically at Haugastøl, situated halfway between Oslo and Bergen, I strapped a GoPro Hero Black 10 on my chest and walked up and down a nearby hill called Storevarden. The walk was approximately 25 minutes up and down, and a fast-forward version of the video can be seen here: ...
