Overview
LMS is a swept sine wave analyzer for legacy PC computers and consists of an ISA full length PC slot card, connector interface cables, the Windows based application software, and includes a calibrated M31 microphone. LMS can be used for production QC testing of loudspeakers, engineering/development of loudspeakers, and a wide array of general purpose electroacoustic measurements.
The LMS system also includes its own precalibrated M31 measurement microphone. Absolute SPL measurements are made at the touch of the mouse! The small size of the M31 mic is also ideal for near field measurements.
The
LMS system provides a vast array of powerful computer based features
which are specifically focused on the unique requirements of loudspeaker
development and QC production testing. While it operates on a "legacy" platform of decade-old PC architecture (i.e. ISA boards, not compatible with PCI slots) the system is robust.

LMS provides the ability to achieve
very high log frequency resolution across many decades of frequency
that typical FFTs can't match.
