Waves TDM Dorrough Stereo Meter

The Waves TDM Dorrough Stereo Meter features models of Dorrough’s most popular loudness meters: 280D/240D, 380D/340D, and 40AES/EBU. Developed in association with Dorrough Electronics, they provide precision loudness monitoring for every conceivable audio scenario. As Input Meters to attain optimal recording levels, as Group/Auxiliary Meters to achieve optimal group loudness, or as Master Output meters, the Waves Dorrough Meters do it all.

About Dorrough
Dorrough Electronics designs and manufactures precision audio and video monitoring devices. For over 20 years, Dorrough has pioneered new technologies in audio signal processing and monitoring for the broadcast, motion picture, and recording industries.

Dorrough Electronics founder Mike Dorrough grew up with a love for radio and an insatiable desire to understand how sound devices worked. In the early 1960's, Mike worked as a sound mixer for a recording company owned by radio icon Casey Kasem and Bob Hudson. During that period, he devised a revolutionary Multi-band (or “Discriminate”) Audio Processing system. By achieving optimum relationships between frequency, time, and amplitude in the complex waveform, Discriminate Audio Processing provided greater loudness with no reduction in fidelity.

The initial success of Discriminate Audio Processing led Mike to a position with Motown and later to RCA Records. Realizing that his system had even greater implications for the broadcast market, in 1965 one of his first Multi-Band Composite Audio Processors was installed at a popular LA radio station.

In 1971, Mike decided to set up his own factory to produce his processors, and launched Dorrough Electronics. Within a few years, a variety of terms widely used in the audio field today like “Multi-band Processing,” “Psycho-Acoustics,” “Relative Audio-Power to Peak Amplitude,” and “Sound-Density” would either be coined or popularized by Dorrough, to describe the effects and benefits of the Discriminate Audio Processor.

Dorrough realized that the perceived loudness of sound is a mathematical function of time and amplitude, and the Dorrough Loudness Monitors grew directly out of the Discriminate Audio Processor. Using patented technology developed to give broadcast and recording engineers a true indication of loudness as perceived by the human ear, Dorrough Loudness Monitors graphically display audio power. Because Average and Peak readings are based on a real-time waveform analysis, the degree of processing, compression, and even distortion are indicated by the relationship between the average and peak indicators.

The patented Dorrough Ballistic is based on the mathematics intrinsic to audio waveforms. The average integrates amplitudes in the context of time, for a true reading of audio power that satisfies both ear and machine. Simultaneously, users are provided with a real time peak, which picks up destructive "burst anomalies" the ear might miss, but that are all too noticeable to recording devices.

The mathematical cohesion between Peak and Average also provides users with a unique window into qualitative aspects of the sounds they are recording. By observing the relationship (gap) between the Peak and Average displays, the user can observe graphically the effects of processing, compression, and even detect distortion. While traditional VU meters are useful for determining average sound levels, and PPM meters are known for their ability to catch fast transient peaks, neither provides both average and peak level displays, which are needed to get an indication of overall program loudness.

Dorrough Meters are fully compatible with AES/EBU standards.
