With rumours of upgrades to the iPhone's audio capabilities set to be announced next week at the iPhone 7 launch, let's look at how this could affect the Hi-Res Audio sector.
It's fairly safe to say that the way we consume music has changed significantly over the last five years. The CD is clinging on, but if Google Trends (see graph below) is accurate this is mostly as Christmas presents. Vinyl has made a comeback among audiophiles. And streaming services have really taken off; Spotify alone receives a greater proportion of Google searches than CDs, overtaking it for the first time in March 2015 and staying ahead for all except the Christmas period.
A lot has changed in the streaming audio sector since I wrote my blog last year. And while outwardly it looks similar, some companies have gone into receivership and others are seriously contemplating IPOs mainly due to the costs involved in delivering a lossless streaming service. Yet the rewards are likely to be great for those that can make it work, so let's see what's happened to the main players in the last year.
Welcome to the second instalment of our Hi-Res Audio Formats overview. In the fist instalment we looked at the Linear PCM (Pulse Code Modulation) encoding scheme used on CDs and which continues to dominate the digital audio world today. If you missed it, you can read the blog here.
Today we are going to look at the other primary format for high resolution audio files, DSD or Direct Stream Digital.
PCM remained as the dominant encoding technique for digital audio until the introduction of the Super Audio CD (SACD) in 1999 which used DSD to encapsulate a higher resolution layer alongside an optional CD layer with the familiar 16-bit, 44.1kHz PCM encoding.
This is the first instalment of a two part blog, which provides a brief introduction of audio formats that have emerged since the 1980s.
Why the 1980s? Nothing to do with frilly shirts and leg-warmers, it was when the tide firmly changed from analog to digital audio. Sure, analog audio still existed in the 1980s (and continues even now) but the focus of technology development switched firmly to digital.
