Many of you have seen/heard me on Scott Wilkinson’s excellent webcast “Home Theater Geek”, which is part of the twit.tv network of webcasts. I was alerted to another show hosted by the head guy at twit Leo Laporte called Triangulation because Neil Young was the guest. I watched the whole thing late yesterday afternoon. It’s time for an update on Pono and the Ponomusic website.
Coinciding with the new interview…and demonstrated on Leo’s show…was the release of the “PonoRevealer” application. According to the Pono website, the PonoRevealer allows listeners of any “high-resolution” song to instantly switch between different formats and different specifications. I’m not sure whether Pono Revealer is two words or not…the video tutorial has it as two but the emails and notices make it one word.
Neil used a version of the Revealer prior to the Kickstarter campaign last year in his souped up Cadillac to impress his rock star friends. Any tune in your Pono library can be prepared for the Revealer. This means that the original 192 kHz PCM files is downsampled and converted inside the player. It’s not as they claim as simple “resolution” change…whatever that means…it’s doing a sample rate conversion from 192 kHz to both 96 and 44.1 kHz AND format conversion from high-resolution PCM to AAC (the format for iTunes downloads including “Mastered for iTunes” processing) and MP3 (at the same quality offered at Amazon). The bitrate of both iTunes and Amazon is 256 kbps, although AAC is generally acknowledged to provide better fidelity than MP3 files at the same bitrate.
