Digital Audio Station Using Pro Logic Software


Before You Begin:


Identification


Make sure that the Digital Lab has the proper equipment to capture the audio format you are trying to convert. The lab currently has equipment that can transfer the following formats:
    • Reel to Reel
    • Turntable
    • DAT
    • Cassette
    • CD
    • Minidisk
  • If you are having trouble identifying your audio format, you may ask Dr. Gracy or consult Audiovisual Formats: A Guide to Identification.
  • Insert the audio format in which you wish to transfer into the correct device.
  • On the sound mixing board, make sure to slide the corresponding white slider all the way up. Figure 1 shows the correct example of how the cassette input slider should be configured. Each slider corresponds with a specific device input:
    • Reel to Reel = Input 1 and 2
    • Turntable = Input 4 and 5
    • DAT = Input 7 and 8
    • Cassette = Input 9-10
    • CD = Input 11-12
    • Minidisk = Input 13-14

Inspection

Make sure the audio you are trying to convert is in good condition. Inspect the tape or record to make sure there is no breakage, wrinkling, scratches, or residue. This is especially important for Reel to Reel. If you are unsure, please contact Dr. Gracy before you begin.

The Recording Process
  1. When you are ready to begin recording your audio, open Logic Pro located in the bottom dock on the computer desktop (lower right-hand side). Once open, choose New-->Empty Project (Figure 2).

    Before you save your new project, make sure that following settings are configured (Figure 3): For
    New Tracks, click Format-->Stereo; For Input, choose the corresponding number that appears on the sound mixing board. For example, for a cassette, choose channel 9-10 in the drop down menu. For Output, leave at 1-2. Make sure that Input Monitoring and Record Enable are checked. Click Create.

    Close the Settings menu.
  4. You are now ready to start recording. In the Pro Logic program, at the bottom of the screen, press Pause first so the recording process is cued up to capture audio. Then press the Record button (Figure 11).

    Figure 11
    Note: be sure play your audio first before recording in order to check the levels on the sound mixing board. The levels should not spike into the red color, but should stay in green. Start playing your audio device (the cassette, Cd. Turntable, Minidisk, DAT, or Reel to Reel). To start recording, press the Pause (not Play) button in Pro Logic immediately after you start playing your audio device. You may toggle the size of the audio frequency by sliding the sliders in the bottom right corner up and down or left and right (Figure 12).
