Hi-Res Audio: Discover the audio formats behind digital music (part 2)

Posted: 29 May 2015
By: 

Welcome to the second instalment of our Hi-Res Audio Formats overview. In the fist instalment we looked at the Liner 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.

Hi-Res Audio: Discover the audio formats behind digital music

Posted: 19 May 2015
By: 

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.

Is 2015 the year of Hi-Res music streaming?

Posted: 22 April 2015
By: 

Emphatically yes! Here we will take a quick tour of the streaming landscape and which service providers are on track to deliver true high resolution streaming not just souped up MP3 at 320kbps, this year.

What is Hi-Res Audio?

High-resolution audio has been formally defined as: "Lossless audio that is capable of reproducing the full range of sound from recordings that have been mastered from better than CD quality music sources."

Typically hi-res downloads are a minimum of 96kHz/24-bit with 192kHz/24-bit becoming popular.

First some background. The way music is consumed has undergone a seismic shift, and 2015 is likely to see another momentum shift with the rise of Hi-Res Audio (see our 5 Key Trends blog for more on this) and the launch of the first true Hi-Res Audio streaming service.

In the last decade the music industry has seen the decline of the CD, the rise (and fall?) of digital downloads and the emergence of on-demand streaming.

On-demand streaming has grown exponentially since the first service was launched, and the latest reports estimate that streaming accounts for more than a quarter of digital music revenues compared to just 3% in 2007. And this trend is expected to continue.

Hi-Res Audio – Yesterday, Today and Tomorrow

Posted: 31 March 2015
By: 

Some of us are old enough to remember going to record stores and looking through the racks of LPs. Occasionally we would even be able to afford to buy one of these precious vinyl discs.

The age of vinyl and Hi-Fi hardware

In the days of vinyl, audiophiles would spend their money on Hi-Fi equipment that could reproduce the music exactly – looking to match the sound that was first heard in the recording studio when the track was originally created. This first wave of Hi-Fi enthusiasts focused on the speakers – purchasing the same type of professional reference monitors that the studio engineers used.
