Cool Stuff: A Box for Low-Bitrate Broadcasters

DaySequerra Eclipse LBR4 Digital Radio Processor

Radio World is featuring winners of its 2011 “Cool Stuff” Award this month.

DaySequerra targets this four-stream AES stereo audio processor to digital broadcasters. Its purpose is to improve audio performance of low-bitrate HD Radio multicasts, DAB and DRM channels with a “particular focus” on stereo at 24 kbps.

The Eclipse uses DTS Neural Loudness Measurement technology to provide loudness measurements and new psychoacoustic processing with look-ahead gain correction to make audio level adjustments that are transparent to listeners. DaySequerra says the proprietary codec pre-processing engine has been “specially tuned” for operation at 24 kbps, 32 kbps, 48 kbps and 64 kbps bit rates to reduce artifacts from lossy codecs and low-bitrate transmission significantly.
