By selecting the beep and using Plot Spectrum you can see that the beep is at 1046 Hz.

Assuming that all of the beeps have exactly the same frequency, you can make the beeps easily visible with the following method:

  1. Make a duplicate of the recorded track (Select the track then Ctrl+D)
  2. Select the duplicate track
  3. Download the attached “1046.xml” file.
    1046.xml (187 Bytes)
  4. Open the Equalization effect from the Effect menu and select the “Draw Curves” mode
  5. Import the 1046.xml file. This will load a new preset called “1046”
  6. Apply the “1046” equalization preset to the duplicate track and it will virtually silence everything in the track except for the beeps, which will become significantly bigger and should be very easy to see.
