HDMI is great for video, but could it be made great for audio too? HDMI is the primary method of transporting AV signals in the consumer environment. It works great with high resolution audio and video, but it has never found its way into the hi-fi world.
Apart from some non-technical reasons, one of the biggest issues associated with HDMI audio is quality of the clock recovered from the HDMI stream and electrical noise associated with it. Despite many improvements in the newest HDMI receiver devices, the recovered clock always suffers from high levels of phase noise. While this is usually not an issue in consumer audio – home theatres, sound bars, etc., in the discipline of critical listening the imperfections of HDMI audio are instantly noticeable. Also, HDMI audio is notoriously known to be sensitive to various forms of electro-magnetic interference, cabling quality, ground loops and in the hi-fi world generally considered as inferior when compared to dedicated digital audio transport methods such as SPDIF, AES/EBU or proprietary links based on the I2S bus.
There is usually nothing wrong with the audio data itself, provided the receiver can take advantage of all the digital formats and sampling rates available on the source side. It is mainly the way the audio data is packed and interleaved with the video data in a high frequency digital signal and eventually recovered on the HDMI receiver (sink) side. There are many cheap HDMI audio extractors in the market, and some of them being able to output digital audio via S/PDIF up to 192kHz sampling rate. But they still don’t come even close to a good digital transport in terms of audio quality.
How is the VanityPRO different from all the other HDMI audio extractors? It basically addresses all the imperfections associated with the HDMI audio, one by one, with a ton of extra features the others don’t have.
