Experimenting with 3rd order spatial transfrorms


Ambisonic 3rd order spatial transform from Trond Lossius on Vimeo.

Yesterday in a video chat, Joseph Anderson suggested some ways of transforming higher-order ambisonic sound fields. This video demonstrates a prototype test of one of them, similar to the ATK Push/Pull transform, but in 3rd order.

Edgelands - New work at Ultima festival



Ewa Jacobsson and Thom Johansen:
Soundcheck for another piece to be premiered tonight.


I have a new work premiering at a concert at Sentralen in Oslo tonight. The work is a commission from NOTAM, and the concert is part of the Ultima Contemporary Music Festival.

A lot of research has gone into the making of this work. It is the first time that I make use of field recordings done using the Zylia microphone that enables recording of third-order ambisonic sound fields. I have also done a lot of research and development into processing and transformations of first- and third-order ambisonic field recordings. Some of this research I presented at the conference in Vilnius last week, and I will also do some demos at the Sonic Wunderkammer workshop tomorrow. The creative process has been an opportunity to revisit thoughts on artistic research and how they relaste to my own practice. Tim Ingold’s book “Making : Anthropology, Archaeology, Art and Architecture” has been a valuable and inspiring conversation partner during the process. Finally comes questions pertaining to the kind of places and soundscapes that I tend to focus on in field recordings; the suburb and the outskirts of urban zones.

From the program notes for the concert:

Trond Lossius is one of Norway’s most prolific sound artists, and in Edgelands he has combined his field recordings of suburbs and city limits, those liminal zones where human activity fades away and nature takes over. An engaging and surprising soundscape merging human infrastructure with the wild.

I would like to thank NOTAM, and in particular former and current artistic directors Notto Thelle and Christian Blom for giving me this opportunity, and Ultima for including it in their festival program. The commission is supported by Arts Council Norway.

Zylia: Comparing plugins



I am listening to some recent field recordings made using the Zylia mic. I first encode them to 3rd order ambisonics and then decode them to binaural (headphones) using the IEM Binaural decoder.

I am shifting back and forth between using the Zylia Ambisonics Plugin and the Sparta Array2SH Plugin for encoding to ambisonics, to compare how they perform. My initial impression is that the Sparta plugin sounds more clean, spatially articulated and open.

The recordings sound pretty amazing at the moment.

One immediate lesson from this is that when I prepare encoded field recordings as part of the post-processing after a field recording excursion, the name of the encoder needs to be part of the filename. This way, if I use the file at a later point, I can review if I need to do the encoding anew.

Granular delay



At the end of the day: A four channel granular delay. Tasty!

Work grant from The Municipality of Bergen



Yesterday I was awarded a work grant from the Municipality of Bergen. I am truly grateful and honoured. The continuous support for the arts from the Municipality of Bergen means a lot to the local art community. For me, this grant offers the possibility to work in-depth over the next year.
