TL MasterMeter uses the DSP power of Pro Tools to model the conversion process found in typical consumer devices. In technical terms, the TL MasterMeter algorithm uses a 31-tap Blackman-Harris windowed sync conversion with oversampling ratios from 2x to 8x depending on the session sample rate. The output of this DSP algorithm is then displayed visually. This assists engineers in highlighting potential distortion which may be introduced on playback of mixes, especially mixes which have been processed to be particularly loud or “hot.”TL MasterMeter can be used in two different ways during a session: Real-Time Metering or Historical Metering.TL MasterMeter can be used to monitor live signal levels, even if the Pro Tools transport is stopped. This can be useful in quickly determining the appropriate level for mixing and mastering.When used in real time, the timecode information displayed in the browsers should be ignored.To gain an overall picture of the levels in an entire session, TL MasterMeter can be inserted on a Master Fader track and the entire session played from beginning to end. This is typically done during final mix and mastering.When session playback is complete, TL MasterMeter shows historical peak and event information for the entire session, as well as a historical list of events in the browsers for both signal clips and oversampled clips. You can then manually examine the relevant parts of the session using the timecode listed in the browsers to determine any appropriate corrective actions.
