The Future of Audio is Personal
 I just returned from another edition of the International Broadcasting Convention (IBC) in Amsterdam. This increasingly influential trade-show is an excellent follow-up to the IFA Berlin consumer electronics tradeshow and provides a broader market perspective from what can be seen at the National Association of Broadcasters (NAB) convention in Las Vegas. It also provides an industry insight to many of the technologies that are normally introduced to the consumer market at the CES Show in January.
I attended the IBC in search for all the missing pieces of information which were lacking since the latest announcements regarding new television and home video distributions formats which have mainly focused on the visual side. Ultra-High Definition (UHD) is the first truly multi-platform audiovisual technology being introduced to consumers, targeting traditional broadcast platforms, IPTV, Internet streaming and physical media. Offering increased image resolution (4K) allowed the industry to also implement significant improvements in Higher Frame Rates (50/60 frames per second or even 120 fps are considered), together with High Dynamic Range (the extension of brightness levels from white to the deepest blacks) and Wider Color Gamut.
 All international industry consortiums and standards bodies represented at IBC 2015 agree that 4K UHD content is the next evolutionary step for the whole industry and, even though there might be some years until broadcasters complete the transition from current HDTV standards, the technology adoption in cable and satellite and certainly in Internet streaming (Netflix being the leading example) is a reality. At IBC 2015, announcements regarding new 4K channels and content distribution from major CDN providers (Amazon, Akamai, etc.) were everywhere.
Among the organizations promoting the technology and, most importantly, the content, the UHD Alliance, is currently promoting unified, premium quality standards to govern the next generation ecosystem - from consumer electronics to content and distribution. The intention is to provide a new and differentiated next generation entertainment experience - through advances in resolution, contrast, color and audio. Licensing of the specification, name and logo is expected to begin early 2016.
At the Amsterdam show it was also obvious that the debate around 4K will not be restricted to Ultra-HD Blu-ray or the distribution of pre-produced content. Broadcasters are discussing the potential for real-time programming - which increasingly is accepted to be the most important revenue stream for traditional (linear) TV services and is also becoming attractive for premium streaming services. Sports, News, reality-shows, all sorts of live entertainment are already being produced in 4K. Still, the discussion about sound remains and not even the UHD Alliance is certain of what will be featured in its soon to be published specification.
 At the IBC 2015 show we have seen impressive demos from Dolby - with its new AC-4 delivery framework, which together with Technicolor's And Fraunhofer's MPEG-H Audio Alliance TV System are currently both candidates for the future ATSC 3.0 television broadcasting system in the US. In Europe, discussions around the new DVB-UHD Phase1 standard also include Dolby AC-4, MPEG-H and DTS:X.
DTS decided to step aside from the ATSC 3.0 race and instead is focusing on promoting the foundation if its DTS:X technology for immersive audio production and object-oriented audio distribution. DTS promotes the technology for content production, theatrical release and distribution to mobile platforms, based on Multi-Dimensional Audio (MDA), DTS' open platform for creation of object-based immersive audio, which has been submitted to the SMPTE for standardization.
In common with all the demonstrations we have attended is the fact that all the fundamental technologies are being introduced to the content-production and broadcast industry not only as "new immersive audio formats" (e.g., Dolby Atmos or Auro 3D) as they have been previously promoted but, instead, focusing on "personalization."
All the demonstrations - Dolby AC-4, MPEG-H and DTS:X - included additional flexibility for viewers to optimize their experience on a broad range of devices, whatever the data rate of the channel. This means that object-based audio or the additional metadata layer which complements the standard multichannel information (from stereo to 7.1 formats) can be applied not only to create immersive experiences, but also for advanced personalization of the user experience - much more attractive for current users.
 Since the end user decodes and renders the object-based metadata on top of channel-based audio, even with live broadcasts, users are able to adjust commentary levels and ambience, independently. This means being able to select different language commentary, selecting between broadcast commentary or listening to communication channels of a sports team, adjusting dynamic range, loudness and selective output level to the playback device. The experience can be freely customized depending on the user device (TV, tablet, set-top-box) and the listening scenario, including the possibility of creating headphone virtualization and full immersive experiences in home-theater installations. It could also be as simple as offering dialogue enhancement or "late-night modes" with optimized loudness and dynamic ranges.
Who knows? As the technology matures and the infrastructure evolves, this could even allow personalization options for users to chose between optimized codecs for low bit-rate or high-resolution lossless audio for playback in high-end equipment. Suddenly, this seams like a whole new and exciting perspective for audio evolution.

Testing the Spin-Clean LP Washer Machine - A Handy System for Cleaning Vinyl Records
By Victor Staggs
The Spin-Clean Record Washer MKII was reviewed in audioXpress April 2013. The company continues to manufacture and hand-assemble the Spin-Clean in Pittsburgh, PA, since 1975, and enjoying international success. The package includes seven drying cloths and enough washer fluid to clean almost 6,000 records and they also sell extra supplies of their non-alcohol-based cleaning solution. The fluid is great for removing dirt, dust, and oily fingerprints from records without harming any of the vinyl's properties, and even works well with moldy records. Read the Review Available Online

Plastic Speaker Cone History
By Mike Klasco
Consulting for multiple loudspeaker and driver manufacturers for more than 30 years, Mike Klasco explains the evolution of speaker cone materials, from paper to the first experiments in plastics and finally to Polypropylene (PP), which became the preferred resin sheet material for thermoformed speaker cones. The article also discusses recent trends in woven composite cone fabrication, like glass, aramids, and carbon fiber. This article was published in Voice Coil, February 2014.
