Meter

With the Sonoris Meter, you can measure peak and loudness levels of audio signals, simultaneously at one scale. Besides a regular meter scale the Sonoris Meter supports the K-System, from Bob Katz, mastering engineer and founder of Digido masteringstudio. The end product closely follows the K-system specifications, including Leq(A) loudness metering and bandlimited pink noise monitor calibration.

The SMTR features an oversampling peakmeter mode. In this mode the SMTR catches intersample peaks that can cause ear fatiguing sound when audio is played on consumer CD players. Many CD players have inferior D/A converters with little headroom that will distort with samples above the clip level. These peaks occur when the audio is clipped (read squashed / limited) or otherwise digitally manipulated (eg. VSTi's). In oversampling mode the SMTR models the D/A conversion process and allows for maximizing the level but avoiding this distortion.

At the bottom of the interface a correlation meter can be found. This meter enables the user to monitor the phase relationship between the left and right channels.
