== Project blog ==

=== April 10 ===
* Demonstration of the WFS system in the Listening room and the ''Fantasia'' video in class.

=== April 12 ===
* First discussion about the piece with Prof. Aquilanti. The other instrument will probably be a cello.

=== April 16-17 ===
* Meeting and discussion with Jens Ahrens at the Linux Audio Conference

=== April 19 ===
* For next class:
** Check Risset's pieces,
** Create a test for the WFS in the listening room.
* Idea: conversion of the trajectories in the solar system to Bezier curves for a smoother contour.

=== April 23 ===
* Tested the MIDI samples salamander (with Qsampler) for the virtual instrument with Nando.

=== April 25 ===
* Implemented a simple plane wave WFS (16 channels) in ChucK.
** Note: ChucK can't handle 32 channels

=== April 29 ===
* Started 3D implementation in Processing

=== April 30 ===
* Started implementation of the WFS in Faust (based on the code of J.O. Smith) to circumveine the limitation of ChucK. Compilation rather as a Jack plugin since a UGen could be limited on a similar way as the tested code last week.

=== May 1 ===
* Started porting solar system code to C++. It should be more efficient than ChucK, the information would be sent to the other part of the piece via OSC.

=== May 3 ===
* Discussed with Nando to get better MIDI samples for the computer-generated piano

=== May 4 ===
* Discussed with Carr to know the status of the Disklavier in the classroom. I'll be checking the system next week to (hopefully) get it to work.

=== May 5 ===
* Porting of the solar system code in C++ completed.

=== May 9 ===
* First prototype for 3D vizualization

=== May 15 ===
* Figured out how to enable OSC support on Faust standalone jack plugins

=== May 16 ===
* Planar wave WFS jack plugin tested in the Listening Room
* New Chuck beta version fixes the running problem for large number of channels

=== May 18 ===
* Implementation of observer movement in the system

=== May 20 ===
* Addition of star background in processing to improve the spatial impression.

=== May 21 ===
* Test of the point source WFS Faust plugin in the Listening Room was unsuccessful. The spatial impression was very disappointing. Reasons for this phenomenon unknown so far.
