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.

Features:

• K-System metering, closely following the K-System specification, with three metering sets:
  1. K12 for broadcast productions.
  2. K14 for home theatre, pop, rock, folk, etc.
  3. K20 for wide dynamic music.
• Regular, non K-system scale also available.
• High resolution metering of peak and loudness levels, on the same scale.
• Intersample peak metering mode.
• Correlation meter.
• Peak-hold function with resettable indicators or 10 seconds hold.

• Pink noise output (left, right or stereo) for monitor calibration of 0dBr / 83dB.
• Adjustable number of consecutive overs before clipping.
• Resettable clipping indicators.
• Resettable clipping incident counters.
• Mousewheel support.
• All samplerates supported.
• Low CPU load.
• Settings can be saved.
• 64 bit resolution.
