NeoDuction technologies – The answer NeoDuction technologies, present the solution to endemic problems and limits to sound communication. They model sound communication as a succession of transduction processes. Each transducer system presents a particular behavior, and imposes limits to the complexity and dynamic resolution they are able to transduct. NeoDuction Optimized Transduction Technologies, can model, virtually correct the behavior and optimize each one of the transducers implied in sound communication. In this way, we can produce... True CD quality music with 64 kbit/s. |
Music streaming - What we loose? Compressed music streams, only include contents that compression system considers enough relevant. Many important things to get a full musical experience are considered not relevant, and in music, as in other fields, real relevance sould not be established only by his relative energy content. If we would compress the human genetic information considering what MPEG or WMA does with relevance, no human, nor insect, nor Antediluvian organism could be obtained. If we would compare the best and the worst interpretation of a musical piece, we will find that differences are “subtle” in energy, but big in cultural meaning to the listeners. |
Sound resolution - Will you notice? What is sound resolution?..., sound resolution is the capacity to reproduce the little and the big contents at the same time. People and industry, makes believe that resolution depends on the number of bits and/or the precision of any of the elements in the the system, avoiding to consider that no usual or even professional loudspeaker/transducer is able to transduct more than around 45 dB of resolution. Simply looking at the specs sheet of any loudspeaker, we will notice that with one watt of power (the best), and continuous signal (the easiest to reproduce), distortion is down around 45 dB below, so any simultaneous signal 45 dB below will have a 100% distortion to fight with. Effective acoustic plans should be included within this range to be transductable, and conventional compression can not arrange this without destroying acoustic plans and musical attacks. |
Intelligibility – The essence of communication? In human languajes, vocals (30 to 300 ms.) are much longer than consonants (10 a 100 ms.), and consonants are much weaker than vocals (up to 27 dB less). As in any other senses, “sensorial masking” makes worst this situation, and... A 10% of the humanity has hearing diseases. At last, we imagine the parts we did not understand to give a meaning to the messaje, and is usual that we invent a 25% or more. The achieved real intelligibility is unknown. |
Transitions - The life of the music? Attacks and transitory contents are the first to be destroyed by information reduction algorithms and system pass band limits. Unfortunately, transitions are the main responsibles of the execution character, and also the principal cause of the differences among instruments. Transitions are how the things happen, and are the principal reason for compressed streams never having the original impact and clarity. |
| About
NeoDuction s.l.
NeoDuction S.L, (formerly acusta laboratories), has been dedicated to the investigation in digital processing for BETTERING THE PERCEPTION OF SOUND AND MUSIC since 1.989. As post-production studios, we have made hundreds of CD mastering and restoring works, serial TV, Film, Omnimax and Spectacular soundtracks, Publicity locutions and treatments of real time broadcast sound optimizing for TV, RADIO and PA, for companies as BMG ARIOLA, PHILIPS, EMI, POLYDOR, HISPAVOX, CBS and others, using the technologies issued from our investigation. Since 2004, we have been preparing industrial firmware solutions to apply a new paradigm to sound producing > streaming > reproducing going beyond the actual limits.. |
