Miranda Technologies’ Automatic Loudness Control (ALC), which eliminates loudness jumps during commercials, is now available with Linear Acoustic AEROMAX™ processing. By incorporating adaptive multi-stage wideband and multiband algorithms from Linear Acoustic, ALC ensures that audio is free from abrupt loudness shifts. The first products available with Automatic Loudness Control are the Densité XVP family of 3Gbps/HD/SD signal processors, including the top of the range XVP-3901 up, down and cross converter with audio processor.

With ALC, the desired Loudness Target, or Operating Level, and Peak Level can be set once, and thereafter the processing offers continuous control, regard¬less of the source. Automatic Loudness Control with Linear Acoustic processing is available in 2, 6 and 8 channel versions, which can provide 5.1 and stereo processing. The output loudness from modules equipped with ALC can be monitored according to ITU-R BS.1770. The XVP-3901 3Gbps/HD/SD up, down and cross converter provides many other advanced audio abilities in addition to ALC. Other options include Dolby E encoding, Dolby Digital (AC-3) encoding, and Dolby E/Digital (AC-3) decoding. Additional audio features of the XVP-3901 include 16 channel embedded audio processing, with automatic delay to keep lip-sync. The processor also provides shuffling, upmixing and down-mixing, loudness metering, and four AES inputs/outputs for additional flexibility.
