Meridian Showcases Hi-Res Audio
Meridian Audio Limited is based in Huntingdon, near Cambridge, UK, and was founded in 1977 by Allen Boothroyd and Robert Stuart. With years of history of innovation and development of the highest quality consumer audio systems, the award -winning company is widely recognized as a world leader in digital and analogue audio reproduction. Meridian developed the world’s first audiophile CD player, the world’s first consumer digital surround controller, developed the MLP lossless packing systems mandated for use in DVD -Audio and now in emerging high -definition disk formats, and is the only UK audio hardware manufacturer to be a member of the DVD Forum. The company’s optical disk players, DSP -based loudspeakers and Digital Theatre systems are unique in the industry, maintaining a super -quality digital audio signal throughout the path from the source to the amplifier, and using digital signal processing to generate advanced crossover characteristics that would be impossible with conventional passive analogue systems. Meridian has recently become the exclusive manufacturer and distributor of Faroudja High -Definition video processors and projectors.
Meridian was instrumental in the early development of the much-anticipated MQA (Master Quality Authenticated) format unveiled in 2014.
People Can Hear The Difference In High Resolution Audio, Study Finds
Listeners can hear a difference between standard audio and better than CD quality, known as high resolution audio, according to a new study from Queen Mary University of London (QMUL).
The study compared data from over 12,000 different trials from 18 studies where participants were asked to discriminate between samples of music in different formats
Dr Joshua Reiss from QMUL’s Centre for Digital Music in the School of Electronic Engineering and Computer Science said: “Audio purists and industry should welcome these findings — our study finds high resolution audio has a small but important advantage in its quality of reproduction over standard audio content.”
Many in the music industry have been split as to whether people can really hear a difference between CD quality music and high resolution audio — even celebrity musicians have entered the fray with new music streaming services: Tidal launched by Jay-Z and Pono players and music service spearheaded by Neil Young and crowd funded through a Kickstarter campaign.
Both streaming services launched in the last two years have been met with scepticism. However, this new study found that listeners can tell the difference between low and high resolution audio formats, and the effect is dramatically increased with training: trained test subjects could distinguish between the formats around sixty per cent of the time.
Writing in the Journal of the Audio Engineering Society, the research suggested that careful selection of stimuli, such as using long samples of more than 30 seconds, may play an important role in the ability to discriminate between the formats.
Dr Reiss explained: “One motivation for this research was that people in the audio community endlessly discuss whether the use of high resolution formats and equipment really make a difference. Conventional wisdom states that CD quality should be sufficient to capture everything we hear, yet anecdotes abound where individuals claim that hi-res content sounds crisper, or more intense. And people often cherry-pick their favourite study to support whichever side they’re on.
“Our study is the first attempt to have a thorough and impartial look at whether high res audio can be heard. We gathered 80 publications, and analysed all available data, even asking authors of earlier studies for their original reports from old filing cabinets. We subjected the data to many forms of analysis. The effect was clear, and there were some indicators as to what conditions demonstrate it most effectively. Hopefully, we can now move forward towards identifying how and why we perceive these differences.”
The samples analysed were mainly classical and jazz music, though it’s not clear for which type of music high resolution recording and playback made the biggest difference.
