With Sonoris Meter you can accurately measure peak and loudness levels of audio signals, at one scale. Besides a regular meter scale the Sonoris Meter supports the K-System, from Bob Katz, mastering engineer and founder of Digido mastering studio. The end product closely follows the K-system specifications, including Leq(A) loudness metering and band-limited pink noise monitor calibration.
The SMTR features an oversampling peak-meter 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 (e.g. VSTis). 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.
