During the CEA Audio Board’s strategy retreat back in June, the issue of the JAS (Japan Audio Society) adoption of Sony’s Hi-Res Audio logo was discussed. The original logo was designed by Sony and has been widely used on their new products and website. It has gained some traction amongst Japanese audio manufacturers. I’ve noticed it on Onkyo’s website.

According to Marc Finer of the DEG, Sony gifted the new logo to the JAS in the hopes that it would be widely adopted and help popularize high-resolution audio. Sony, as you may or may not know, is pushing high-res very aggressively with a line of new HD players, portable devices, and headphones. They’ve really taken the lead in the CE space.
Marc told the assembled group that the JAS was willing to make the logo available to the CEA to promote high-res audio in the states. Having a unifying logo couldn’t hurt the effort. We haven’t seen all of the details but it was a topic of discussion on today’s board call.
Back in June, I didn’t know any specifics about the logo or the associated “minimum specifications” that need to be satisfied in order to be able to license and use the logo. But I did know what was happening to the process of trying to define high-resolution audio in our CEA group. What should have been an open and meaningful debate and discussion was overrun by other parties and participants with the end result being a definition that is completely meaningless.
The DEG, CEA, NARAS and the major labels issued a press release back in late June defining “high-resolution audio as anything better than a compact disc”. And then they went on to accept any recording ever made as “high-resolution” just as long as it was converted to format better than a CD…including a CD to 192 kHz/24-bit transfer. It’s strange but true. I had off the record discussions with a number of the committee members about how flawed the existing definition was but nothing has been done to improve it. And now we’re being asked to consider a new hi-res audio logo.
But there’s hope. I received a single page PowerPoint deck that spells out what it takes to be able to use the Hi-Res Audio logo. Here’s it is:

This document is very good news…not an ultimate solution, but it does avoid the pitfalls that the DEG and others fell into. This is the JAS laying out the minimum specifications that have to be “satisfied” in order for a company to use the hi-res audio logo.
The left hand column lists the various processes that happen in the production and playback of a music recording. This includes the quality of the microphones, the recorder, the digital interface (I/O to and from the recorder), the encoding format (which require FLAC and WAV), the specs for DSP processing, the conversion from digital to analog, and finally the amplification. Wow! This is a very comprehensive list. Our group never even touched on any of these items.
The minimums standard for the digital part of the signal path is 96 kHz/24-bit PCM (notice they don’t include DSD anywhere…I’m surprised since Sony was the source of the logo). The analog portion of the signal path is put at 40 kHz or roughly twice the traditional maximum frequency for human hearing. This standard sets a pretty high bar.
The JAS is on to something. I’m very impressed. The DEG, CEA, NARAS, and major labels should be paying attention. Here is a definition that has some meaning. It’s clear and accurate. It’s not mushy and willing to accommodate every analog recording, DSD tracks, and CD quality PCM.
What is doesn’t do is speak to the provenance issue that still looms large. But it’s a huge step. If the CEA adopts the JAS high-res audio logo, then anyone that wants to use this logo would have to up their game to meet it. At least the hardware folks will. The content providers…that’s an entirely different issue.
