You are here: Signal Processor Emulation

Students will learn to operate common signal processors using "plug-in" models found in audio recording software such as Digital Performer. 
Teaching and Learning Methodology
First, the instructor will prepare suitable audio files that contain background noise, poor tonal quality, dry signal, etc., that students will improve using compressor, equalizer and reverberation plug-ins. Next, the instructor will prepare Digital Performer files that contain the problematic sounds and plug-in settings that correct the defect. For example, a Digital Performer file emulating equalization would contain files with excessive hiss or rumble and plug-in circuits with low or high pass filters pre selected. The students will then adjust the cut-off frequency to hear the filter performing.

Each demonstration portion of the sub-topic must explain the basic functions of the processor and illustrate their use with appropriate sound files.  Since some students prefer auditory modes of instruction, one might wish to record the written instructions as a Quicktime movie and import it into the Performer file. Each sub-topic should also test the student's comprehension by having them match processor settings to files already altered by the processor. Digital Performer allows one to do this by synchronizing two tracks (one dry and one processed) and soloing between the two. The student then adjusts the parameters so that the timbres match.
