CLEANING ‘VINTAGE’ DIGITAL AUDIO FILES
Suppose you have an older digital audio file that you would like to bring up to date.
The RESTORATION SUITE Plug-Ins can manage sample rates from 22 kHz to 192
96 kHz. If you are cleaning an older file, such as an 8 kHz 8 bit file, it is advised to
convert the Sample Rate from 8 kHz to something more contemporary, such as 96
kHz. This can be done in a number of audio utilities such as Wavelab or SPARK XL.
Once you have re-sampled your audio material, you follow the steps described in the
‘CLEANING AUDIO’ portion of the manual earlier in the tutorial.
APPENDIX A: PROCESSING DELAY AND LATENCY
In addition to the typical latency delay associated with DSP Plug-Ins, RESTORATION
SUITE Plug-Ins also have an internal processing delay that the COMPENSATOR Plug-
In does not compensate for. NOTE: This latency is in ADDITION to the latency of
POWERCORE and varies by Plug-In.
The following chart will provide you with offset values, in samples, for each Plug-In at
specific sample rates. If you use the RESTORATION SUITE Plug-Ins as inserts in a
multi-channel application, you will want to set your track backwards in time in order
to line up with the other tracks in you mix.

You will notice that Declick has a constant latency value, while Denoise and Descratch
have dynamic latency values. This is required to maintain the high resolution of
processing at all common sample rates.
AUTOMATIC PLUG-IN COMPENSATION
Most multi-track host applications have automatic Plug-In compensation only for track
inserts, and under most circumstances, this is the best solution for managing latency.
AUTOMATIC PLUG-IN DELAY COMPENSATION IN LOGIC AUDIO
Logic Audio will compensate a maximum of 8820 samples, which can be inadequate
for use with a session that contains the Descratch Plug-In as an insert in a channel or
group. If you are using Logic Audio, disable Automatic Plug-In Delay Compensation
and only use manual methods of compensation. Any automatic compensation solution
will result in timing errors that cannot be fixed with the TC COMPENSATOR Plug-In.
Do not use a TC COMPENSATOR Plug-In in Logic when ‘Automatic Plug-In Delay
Compensation’ is active!
