All activities within the Signal Processor Emulation module require the use of a Macintosh G3 computer (or better) and Digital Performer 2.7 (or higher) software. To conduct the following activities in their entirety, you will need to download a StuffIt archive containing sample audio files and a Quick Time movie. Clicking on the link below will begin the download process.

Important Note: The archive file is quite large. It is not recommended that you attempt to download it if you are connected to the Internet using anything less than a high-speed connection (i.e. cable modem, T-1 line, DSL, etc.) If you do not have access to a high-speed Internet connection, please send a message to the Texas Collaborative Clearinghouse to request a copy of a CD-ROM containing all files for the Signal Processor Emulation module.

Activity 3.1
Reverberator Demonstration

Demonstrate common uses of reverberators.

Using audio files of single tracks and mixing windows of multiple tracks, students will adjust common effect send, reverberation and effect return settings.

Using a virtual mixing board with channels for audio, effect sends and reverb returns, students will apply reverberation settings, audio levels and return levels of dry and wet tracks. One example will use a single audio track to make the quality of reverberation easy to hear. Another example will contain multiple tracks for the student to mix.

Materials Provided
Audio files of a drum kit.
Reverb demonstration worksheet (.doc or .pdf)

Activity 1.2
Reverberator Drills

Identify reverberation settings by ear.

Using audio files of drums, students will compare their reverberation settings with pre-recorded ones, matching the setting of the reverberator. Only one setting will be matched as automation will keep the other settings from being changed.

Drum tracks using different room, reverb time, low pass and pre-delay times are prepared for student to listen to. Student will identify the setting changes by matching them with a reverb plug-in they can adjust. To reduce the variables, plug-in automation will prevent certain controls from changing. A review sheet will pose questions for the students to answer.

Materials Provided
Drum tracks with reverb plug-in settings
