Smaart has been compared to other software-based sound system measurement tools such as SIM by Meyer Sound Laboratories and IASYS by Audio Control, both of which offer delay finder tools. [11] Smaart has been described as "a newer, slimmer and much cheaper—but not necessarily better—version of the Meyer SIM system."
The measure of the low frequency (many tens of Hz) noise contributed by the turntable of an analogue playback system. It is caused by imperfect bearings, uneven motor windings, vibrations in driving bands in some turntables, room vibrations (e.g., from traffic) that is transmitted by the turntable mounting and so to the phono cartridge.
The human ear responds quite differently to clicks and bursts of random noise, and it is this difference that gave rise to the CCIR-468 weighting curve (now supported as an ITU standard), which together with quasi-peak measurement (rather than the rms measurement used with A-weighting) became widely used by broadcasters throughout Britain ...
Dynamic range is a measure of how small you can measure a signal relative to the maximum input signal the device can measure. Expressed in decibels, the dynamic range is 20 log (Vmax/Vmin). For example, a device with an input range of ±10 V and a dynamic range of 110 dB will be able to measure a signal as small as 10 μV.
Microphones, amplifiers and recording systems all add some electronic noise to the signals passing through them, generally described as hum, buzz or hiss. All buildings have low-level magnetic and electrostatic fields in and around them emanating from mains supply wiring, and these can induce hum into signal paths, typically 50 Hz or 60 Hz (depending on the country's electrical supply standard ...
Measurement Studio 7.0 adopted support for .NET and allowed for native .NET controls and classes to integrate into Visual Studio. As of Measurement Studio 8.0.1, support for Visual Studio 2005 and .NET 2.0 framework have been included, with support for Windows Vista first adopted in version 8.1.1.

A tetrahedral chamber is capable of measuring the low frequency limit of the driver without the large footprint required by an anechoic chamber. This compact measurement system for loudspeaker drivers is defined in IEC 60268-21:2018, [1] IEC 60268-22:2020 [2] and AES73id-2019. [3]
