Create sensible file names for files from ZOOM audio recorders

Zoom recorders name their files ZOOM0001.WAV, etc. This is not terrible informative. I made a script to auto-generate file names based date of modification of file (to be accurate you need to set the date correctly in the recorder). It is a Haskell script using the turtle and WAVE packages. To run it make sure the packages are installed and do “runhaskell rename_zoom.hs /path/to/your/files”.

audio-DH: sonic manifestations by 250 creators from Den Haag/The Hague

I have submitted a short piece for ‘audio-DH’, a collaborative project involving artists somehow related to Den Haag. An official public presentation/premiere will take place at Korzo Theater as part of TodaysArt Festival, on SEPTEMBER 22nd, although I will not be present.

The project ‘audio-DH’ presents the work of 250 experimental artists/creators from/based in The Hague. Some fifty invited curators have collaborated to probe the waters -both those normally reached by sunlight and other, more bathyal, ones- of the sonically adventurous creative ocean that has been persistenty flooding the city of The Hague for quite some time now.

Forcefully illustrating the worldwide, decades-long, explosive and expansive ‘socialization’ of creativity; including all kinds of groups, ideologies, collectives, generations and aesthetics; and encompassing the wide spectrum of ‘experimental’ practices –from noise to contemporary, from improvised to algortihmic, from documentative to highly composed- ‘audio-DH’ aims at unequivocally placing The Hague in its rightful place as one the most sonically creative cities in the world.

In addition to the individual work of the artists/creators involved, this project presents the results of a specifically developed software –aptly named ‘HARING’- that autonomously recombines and transforms all these sonic contributions into a new mega-composition. Taking center stage, and unassisted by any human controller, ‘HARING’ will perform the presentation concert of ‘audio-DH’ in Korzo Theater.

A simple music library browser using dmenu

I have a large music library, and all programs that I have tried (in Linux) are sluggish. Mostly I just want to select an album to play, and I want to do that quickly. I cooked up my own solution, a Haskell script that launches dmenu to select an album. It is instantaneous, I can get to an album from anywhere in the system in 3 or 4 seconds (I have the script assigned to cmd-alt-m). It requires generating a text file with all the music folders in the disk which should be updated regularly, I have also created a Haskell script for this. It uses the excellent turtle Haskell package for scripting. It also keeps track of the history of played albums.

Debian – getting a lowlatency kernel.

For audio work a lowlatency kernel or an rt-patched kernel should be used. Lowlatency is enough in most cases. Personally I’ve found that only an rt-patched kernel was capable of avoiding x-runs.

In Debian you can get an rt-patched kernel directly from the main repository. To install a lowlatency kernel, though, you need to compile one yourself, but that is quite easy. In the steps below change the version number to match the version number you want to use.

apt-get install build-essential fakeroot
apt-get build-dep linux
apt-get install libncurses5-dev libncursesw5-dev
apt-get install linux-source-4.2
tar -xaf /usr/src/linux-source-4.2.tar.xz
cd linux-source-4.2
cp /boot/config-4.2.0-1-amd64 .config
make menuconfig

In the gui:
enable preempt
enable timers 1000Hz

make -j4 deb-pkg LOCALVERSION=-lowlatency KDEB_PKGVERSION=$(make kernelversion)-1
cd ..
dpkg -i linux-headers-4.2.5-lowlatency_4.2.5-1_amd64.deb 
dpkg -i linux-image-4.2.5-lowlatency_4.2.5-1_amd64.deb
