[LAU] Audio measurement at LAC 2014

LAC 2014 wil start in less than 48 hours, with what looks like a fully charged program of papers, workshops, installations and concerts. For those interested in audio measurements, there will a paper by Robin Gareus about audio metering (in a production context), and yours truly will present a workshop about audio measurements (i.e. the more technical side). The workshop will start with some essential theory (no rocket science maths), followed by hands-on practice. If you attend the workshop you can bring your laptop and audio interface [*] and have it calibrated against a precision RMS meter so you can later use it to measure other things. Make sure to have jaaa and jnoisemeter installed in that case. The best audio interfaces for this sort of thing are those having fixed or at least exactly repeatable analog gains. I'll also introduce some python extensions and code I've been using to measure audio HW and SW. For this you will need python, numpy, scipy and matplotlib. I'm using python 3.4, but things should work with 2.7 as well. See you in Karlsruhe ! [*] Internal audio interfaces are usually not worth the effort. Also, we'll have an assortment of XLR, TRS and RCA cables but no 3.5mm jacks ! -- FA A world of exhaustive, reliable metadata would be an utopia. It's also a pipe-dream, founded on self-delusion, nerd hubris and hysterically inflated market opportunities. (Cory Doctorow)
