A lightly used industry-standard loudness meter. If you're trying to make your stream, audio files or podcasts consistent in perceived level from production to production then you need a LUFS meter to check that you're at the right level. This unit can show either conventional peak reading levels or the current LUFS value. Full details may be obtained from the User Manual at https://www.prostudioconnection.net/2103/LM100_User_Manual.pdf. I don't have any of the software files but previous purchasers have been able to obtain them from the Dolby Customer Support portal (but this is not guaranteed). In my testing I was able to configure all of the important parameters via the front panel interface.
The Dolby LM100 Broadcast Loudness Meter is a tool for measuring the subjective loudness of dialogue within broadcast programming.
Differences in audio levels between programs, or between programs and commercials, are a major annoyance to TV viewers. However, although obvious to the viewer, these differences have proven difficult for broadcasters to measure with conventional methods and equipment. The Dolby LM100 Broadcast Loudness Meter solves that problem through Dialogue Intelligence, a revolutionary technology developed specifically to measure the perceived loudness of dialogue.
Research shows that most viewers adjust TV volume to normalize dialogue levels. By analyzing the input signal and measuring program loudness only during the presence of speech, Dialogue Intelligence objectively measures what viewers subjectively experience.
Applications for the LM100 range from postproduction and quality control to final transmission, program turnaround, and cable head-end facilities.
Easy-to-Read Measurements - The LM100 utilizes ITU-R BS.1770-1 as its core measurement algorithm. Users can also select Leq(A).
The LM100 presents its measurements in an easy-to-understand numerical format. This eliminates the variations in results multiple operators often find when using VU or PPM meters, neither of which was designed to measure subjective loudness.
The LM100 can also determine the unweighted peak and a range of other information about the signal. The unit can simultaneously display the incoming
dialogue normalization (dialnorm) value of a Dolby Digital program (or any program within a Dolby E bitstream) for direct comparison to the actual measured value.
Front- and rear-panel serial interfaces provide capabilities for software updates and the LM100 software remote application. The remote application will assist users with advanced loudness measurement, logging features, and enhanced error reporting.
A set of user-definable alarms and monitoring functions can inform an operator of input loss, signal clipping, overmodulation (LM100-NTSC version), high or low signal levels, silence, and incorrectly set dialnorm values.
