Some thoughts on non-linear presentation tools

Many people rely on what I will call linear presentation tools when they lecture. This includes software such as LibreOffice Impress, Google Presentation, MS PowerPoint, or Keynote. These tools are great for smooth, timed, linear lectures. I also use them from time to time, but mainly if I know exactly what to say. They are also good when I lecture with others, and we need to develop a presentation together. However, linear presentation tools do not work equally well for general teaching, where spontaneity is required....

Sound and Music Computing at the University of Oslo

This year’s Sound and Music Computing (SMC) Conference has opened for virtual lab tours. When we cannot travel to visit each other, this is a great way to showcase how things look and what we are working on. Stefano Fasciani and I teamed up a couple of weeks ago to walk around some of the labs and studios at the Department of Musicology and RITMO Centre for Interdisciplinary Studies in Rhythm, Time, and Motion....

Running a hybrid conference

There are many ways to run conferences. Here is a summary of how we ran the Rhythm Production and Perception Workshop 2021 at RITMO this week. RPPW is called a workshop, but it is really a full-blown conference. Almost 200 participants enjoy 100 talks and posters, 2 keynote speeches, and 3 music performances spread across 4 days. A group photo of RPPW2021 participants, taken in a Zoom Room before the last poster session....

Running a successful Zoom Webinar

I have been involved in running some Zoom Webinars over the last year, culminating with the Rhythm Production and Perception Workshop 2021 this week. I have written a general blog post about the production. Here I will write a little more about some lessons learned on running large Zoom Webinars. In previous Webinars, such as the RITMO Seminars by Rebecca Fiebrink and Sean Gallagher, I ran everything from my office. These were completely online events, based on each person sitting with their own laptop....

New publication: NIME and the Environment

This week I presented the paper NIME and the Environment: Toward a More Sustainable NIME Practice at the International Conference on New Interfaces for Musical Expression (NIME) in Shanghai/online with Raul Masu, Adam Pultz Melbye, and John Sullivan. Below is our 3-minute video summary of the paper. And here is the abstract: This paper addresses environmental issues around NIME research and practice. We discuss the formulation of an environmental statement for the conference as well as the initiation of a NIME Eco Wiki containing information on environmental concerns related to the creation of new musical instruments....

Normalize audio in video files

We are organizing the Rhythm Production and Perception Workshop at RITMO next week. As mentioned in another blog post, we have asked presenters to send us pre-recorded videos. They are all available on the workshop page. During the workshop, we will play sets of videos in sequence. When doing a test run today, we discovered that the sound levels differed wildly between files. There is clearly the need for normalizing the sound levels to create a good listener experience....

Making 100 video poster images programmatically

We are organizing the Rhythm Production and Perception Workshop 2021 at RITMO a week from now. Like many other conferences these days, this one will also be run online. Presentations have been pre-recorded (10 minutes each) and we also have short poster blitz videos (1 minute each). Pre-recorded videos People have sent us their videos in advance, but they all have different first “slides”. So, to create some consistency among the videos, we decided to make an introduction slide for each of them....

Launching NOR-CAM – A toolbox for recognition and rewards in academic careers

What is the future of academic career assessment? How can open research practices be included as part of a research evaluation? These were some of the questions we asked ourselves in a working group set up by Universities Norway. Almost two years later, the report is ready. Here I will share some of the ideas behind the suggested Norwegian Career Assessment Matrix (NOR-CAM) and some of the other recommendations coming out of the workgroup....

Combining audio and video files with FFmpeg

When working with various types of video analysis, I often end up with video files without audio. So I need to add the audio track by copying either from the source video file or from a separate audio file. There are many ways of doing this. Many people would probably reach for a video editor, but the problem is that you would most likely end up recompressing both the audio and video file....

Strings On-Line installation

We presented the installation Strings On-Line at NIME 2020. It was supposed to be a physical installation at the conference to be held in Birmingham, UK. Due to the corona crisis, the conference went online, and we decided to redesign the proposed physical installation into an online installation instead. The installation ran continuously from 21-25 July last year, and hundreds of people “came by” to interact with it. I finally got around to edit a short (1-minute) video promo of the installation:...
