Meridian invented Meridian Lossless Packing, the mandatory lossless format selected for DVD-Audio in 1998. Meridian and Dolby Laboratories, Inc. co-developed Dolby TrueHD, selected for Blu-ray Disc in 2005, based on MLP.
• Lossless encoding/decoding for Blu-ray Disc (2005: WinMLP, Dolby Media Producer)
• Editing Dolby TrueHD Streams for seamless connections (2009: Dolby Media Producer, 2010: Sonic Solutions Scenarist)

From the development of lossless encoding and decoding systems that have become embodied in international standards for both consumer and professional audio, to three-dimensional with-height surround sound based on principles developed in the UK, Meridian's research and development team is at the forefront of research worldwide.
Meridian pioneered high-resolution digital signal processing for audio with work on filter topologies, noise-shaping to maximise the dynamic range available in a channel, upsampling and apodising.
• Double-precision feedback filtering (1991: D6000 DSP Loudspeaker)
• Noise-shaping (1995: 518 Resolution Enhancement)
• Double-precision feedforward and feedback filtering (2000: DSP8000 DSP Loudspeaker)
• Apodising filters (2007: 808.2 Reference CD Player)Meridian brings the best of spatial sound to its customers for both music and movies. Innovative Trifield and Ambisonic technologies have been included in Meridian surround sound decoders from their introduction in 1994. Meridian was the first with a DSP implementation of ProLogic (1994), Dolby Digital (1995) and DTS decoding for 5.1 (1996).
• The 861 Surround Controller is capable of driving loudspeakers delivering height information as well as speakers in the horizontal plane for a fully immersive three-dimensional audio experience.
• Meridian demonstrated full 3D (with height) immersive Ambisonic sound at the 2007 UK AES Conference.
• Meridian’s popular M80 compact sound system employs proprietary stereo widening techniques to create a large sound from a small box.
• Meridian Room Correction controls the interaction between loudspeakers and room, using automatically generated filters to manage the reverberation time of the room modes for optimum clarity and localisation.Meridian introduced the first DSP loudspeaker – the D6000 – in 1991, combining the best of DSP filters, active electronics and acoustic design. Additional algorithms for DSP Loudspeakers include:
• Dynamic bass extension (1993: DSP5000 DSP Loudspeaker)
• DSP drive-unit thermal protection (2000: DSP8000 DSP Loudspeaker)
