The EAP-3901 is an advanced embedded audio processor which can simultaneously process up to 32 channels of audio (16 channels of embedded audio from the video plus others generated internally). Functions include down-mixing, proc amp, channel shuffling and mixing. Options include automatic loudness control, dynamic processing (limiter, compressor and expander) and loudness measurement. The EAP-3901 generates audio/video fingerprints (via an iControl option) to detect and measure lip sync errors in a broadcast facility. The new loudness measurement option allows the measurement and logging of up to four audio programs with iControl loudness monitoring software to analyze and report compliance with respect to various loudness regulations.
