Research and development of software, hardware and services for audio

New technologies and formats for production, distribution and reproduction of spatial, personalizable and interactive sound

The market for digital sound media is quite diversified. New paradigms go with solutions which are flexible, reconfigurable, interactive, scalable and personalizable.
We conduct research and developments projects in audiovisual engineering. In our projects we priorize the use of state-of-the-art technologies in digital coding, multichannel audio and sound immersion (sound 2D/3D).

Services we can do:
• Applied technological research
• Research and development of software, IP's, DSP algorithms, audio circuits and equipments - eg. scalable amplifiers, high-density channel sound distribution systems, etc.
• Design and implementation of audio and video solutions, specific applications and services.

Surround decoders: example of a mpeg-aac decoder with multichannel output, for surround sound.

Some examples of technologies we can work with:
• 2D/3D audio
• Surround n.m (5.1, 6.1, 7.1, 10.2, etc.)
• Coding and decoding of multichannel audio in several formats: MPEG-1/2, MP3, AAC, MP4, MPEG-4 and MPEG-7
• SAC (Spatial Audio Coding) and MPEG Surround
• Ambisonics, Wave Field Synthesis
• DVD-Audio, DSD/SACD, WMA, OGG Vorbis, FLAC, and others
• Protocols for distribution/transport of audio.

Sonic Virtual Reality: example of a virtual sound space, creating a sensation of the instruments positioned surrounding the listener.  

Areas we can develop solutions and applications, and implement strategic conception of new products and services:

  • Technologies for multichannel and surround sound production
  • Interactive digital music/audio players (for desktops e portable)
  • Software for sonic virtual reality
  • Surround players and decoders
  • Sistems for acoustic rooms simulations, for production, edition and projection of acoustic sound scene 3D.
  • Loudspeakers arrays/matrixes for immersive audio
  • User interfaces for playing platforms and audio processing programs
  • Modules (hardware and software) and audio sub-systms for DTV receptors and home-theaters
  • Transcoding among multichannel and surround audio formats
  • Compressors (encoders) in high definition (HD)
  • Systems for coding and classification
  • Systems for storage and distribution
  • Software for music analysis, processing and synthesis
  • Technologies for managing sound material/content

We also work with training and technical education in multichannel audio and surround.

Clients: companies developing products, solutions and audio programs and multimํdia systems; professional audio consumer audio industry; service providers; broadcasters (market TV and digital radio); institutions for education, training, research and development; multichannel audio systems users
