Interview Questions

I have recently been on the job hunt (and come out of it with a new job, thanks for asking). I talked to a number of interesting organisations and answered a proportionally  interesting number of questions. No less interesting is that fact that nearly all of these questions, whilst being ideal interview material, were also the kind of questions that would come up every day as part of the job.

Global object appears not to load in Play framework

Visualising folk tune structures

Traditional tunes have a particular shape to them. Many, especially northern European, have two parts, each repeated, possibly with first and second time bars. Within this arching structure that spans the tune in a few leaps, there are smaller repeated phrases, callbacks and variations. I remembered a visualisation I saw a long time ago which took a MIDI file and visualised the structure. I wanted to do something for the tunes in FolkTuneFinder.

The trouble with buttons without captions

Oxford Laptop Orchestra – Lecture 4 — Modulation

oxlork

This is number 4 in my series of lectures in music technology and ChucK to the Oxford Laptop Orchestra. Delivered on the 5th of November 2012 at the Faculty of Music. Give the first three a read before reading this.

The content is complete here (except for a bit about Nyquist) so feel free to read this. But I intend to do a bit of copy-editing, and include sound samples before I declare it complete.

This week we look at low frequency oscillators, using them to modulate other oscillators and in the process how to do more than thing at once.
