Phase:  Engineering

Version:  None

Summary of Activities:

As mentioned in the weekly summary, one of this week's objective is to complete the functionality of the delay/filter section, which is on schedule and nearly completed.  The only step left is to complete functionality of the comb filter.  As promised, the following is a screenshot and a summary of the updates made to the surround1 sub patch and the prototype module.

Seen on the right of the first screenshot above (the prototype module), the delay filter section will allow the user to apply a delay as well as a filter to the signal.  The filter section comprises of an on/off toggle, filter type selection (6 types total), and channel selection. The delay section contains an on/off toggle, delay length (ms), and channel selection. The user will have the capability to shape the timbre as well as the finite time in which recorded material will play, thus reproducing acoustic effects found within our urban environment.

Additional Information:

Filter types

Notes:

As the first objective of this week is nearly finished, the next stage will be started by Saturday.  This includes some testing/debugging of the prototype module as well as the beginning of the duplication process.
