But there is a limit what can be done for severely damaged discs (without investing in very expensive tools). On
very damaged records, you may be forced to decide between a “natural” sound which contains a few residual
defects, versus a more heavily processed sound which has collected new annoying artifacts to replace the old
annoying defects.
PG RTA DirectX Plug-In
The PG RTA Real Time Analyzer plug-in displays a third-octave frequency graph of a single track or the entire mix,
to find proper equalization settings.
The PG Real Time Analyzer is ONLY a frequency measurement tool. PG RTA never modifies the audio.
Control Descriptions
Enable Plug-in Checkbox
Toggle the checkbox to turn the RTA ON or OFF.
PG RTA only does processing when:
1. The plug-in is enabled.
2. The plug-in is visible.
If PG RTA is not enabled or it is not visible, it does not add to the computer load during playback.
It does no harm to leave several instances of the plug-in assigned to various Tracks, Aux Returns, or Masters.
When you don’t have the plug-in visible on-screen, it will not load down the computer.
Frequency Resolution
The Octave button displays ten bands, representing the level of each octave in the audio. The Third-Octave button
displays 28 bands, representing the level of each third of an octave in the audio.
There may be situations where it is more useful to have a 'general' overview at octave resolution, but the main
reason you might prefer Octave resolution is to reduce the CPU load. Compared to third-octave resolution, Octave
resolution only presents one third of the computer load.
Channel View
Channel View is only meaningful when metering a stereo track, or Aux/Master inserts (which are almost always
stereo). The Channel View setting has no effect on a mono track.
If metering a stereo insert, select the Left+Right button to view the summed frequency response of both the Left and
Right channels. Select the Left or Right buttons to view only one of the channels.
Zoom In/Out (Adjust the vertical amplitude resolution in dB.)
If a track has wide dynamics, zoom out to see all the bands without scrolling. If zoomed out too far, it can be
difficult to visually judge frequency levels. All the bands may appear about the same level.
