With the development of digitalization and Omni Media, Volume changes of sound on vision between materials, programs and channels comes more normal and intolerable by listeners. That also makes loudness increasingly concerned.

SLALC series Embedded audio Loudness processor adopt the latest loudness control technology, DSP technology, multiband processing, and real time forecast, calculation, filter, weighted according to the ITU - R BS1770 standard. Automatic processing to embedded audio within preset loudness range, SLALC with fast response, low latency, high stability, effectively avoid the volume differences, maintains the total energy in appropriate loudness not only intensity.

SLALC Embedded Audio Loudness Processor is widely used in all levels of radio and television stations, studios, vans, computer rooms, government, schools, enterprises and institutions, etc.
