Welcome to our latest guest blog, where XMOS customers discuss their experiences of using xCORE multicore microcontrollers.
Joining us this time is Dominic Baker, Technical Director at Cambridge Audio.
For more than 40 years, UK-based Cambridge Audio has been at the forefront of hi-fi innovation, designing and building a range of award winning products for music lovers. Each product is designed to deliver the best performance and sound quality from a range of sources.
Back in March of this year we announced a first for XMOS … a dedicated audio processor, called xCORE-AUDIO Hi-Res 2. Well we’ve had the samples back in our lab for a while now and the device is now ready to be let out into the wild. Here at the factory we are very excited about the new development.
So what is xCORE-AUDIO Hi-Res 2?
Simply put it’s a dedicated audio processor which offers high resolution stereo (hence the 2 … clever eh?) audio interfacing for consumer audio applications such as DACs and headphone amplifiers.
Welcome to the second in our series of featured guest blogs, where XMOS customers discuss their experiences of using xCORE multicore microcontrollers.
This time out we talk with Thorsten Loesch, Director of Technology for iFi Audio.
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.
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.
Welcome to the first in our series of featured guest blogs, where XMOS customers discuss their experiences of using xCORE multicore microcontrollers.
First up we talk with Jason Liao, CTO and VP Product Development of OPPO Digital, Inc. OPPO Digital designs and market high quality digital electronics that deliver style, performance, innovation, and value to A/V enthusiasts and savvy consumers alike. OPPO’s attention to core product performance and strong customer focus distinguishes it from traditional consumer-electronics brands.
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.
So you love your music. You value those immersive moments in sound. You’ve got the high end headphones. But still something is missing. The music lacks the depth and clarity of a live performance. Could a DAC (Digital to Analog Converter) be the answer? In this blog we explore the world of DACs, what they are and why you should consider using one.
Is the audio market finally getting to grips with Hi-Res Audio (HRA)?
Here are 5 key trends emerging in this competitve and fast paced market.
