Dublin, Ireland May 4, 2021 (Issuewire.com) - Intonation Audio Technology today announced the launch of a technique to recover the information lost in digital recording and preserve the analog quality sound. Intonation's ghost audio technology process retrieves the vital lost information originally discarded by the computer's indiscriminate compression during the digital recording process.
Their arc (analog recovery class) system preserves the now-analog recordings in their full original analog sound integrity, "cocooned" inside digital files. This is not an AD/DA conversion, it is ultimately a DA/AA - AA re-build. These two processes work in tandem and in real-time. The technology allows the vinyl to be realised as if printed from pure analog. This is a world first.
The technology also serves as the basis for another innovation, their mtt (muse tape technology) process which is designed for audio streaming and download. Built on ghost audio and arc technologies, it allows for full analog sound to be held in small file sizes suitable for download.
With Intonation technology 1.47 GB digital (AD/DA) audio is now available as original 384 kHz analog quality sound preserved in a digital file of 4.8 MB with no loss of integrity and information. This is an AA/AA vinyl on your portable digital player, streamable at 44.1 kHz.
While better audio quality is now available for streaming at 192 kHz, such as from Tidal and Amazon, it is still digital and does not carry the true analog sound. At the core is a set of proprietary algorithms built upon combined hardware and tape technologies, all engineered by Intonation.
Developer Dr. Kerrin McKenzie explains: "Having experience working with tape and electronics from the late 1970s onwards, we began to have ideas which demanded exploration and testing. This was the start of a long enquiry into the technology behind digital audio recording, its limits, and its possibilities, particularly when we realised pure quality analog sound could be preserved in its entirety through our newly developed algorithms and AIA. The arc breakthrough, when it came, was incredibly exciting in enabling us to preserve pure quality analog sound in the digital domain. Meanwhile, we had also been working to see if we could reclaim the analog detail which was lost in digital recording. This resulted in the ghost audio technology process, developed to work concurrently with an arc. The final breakthrough was when we worked out how to reduce the file size without compromising the analog integrity of the sound, the process which we call mtt."
''Intonation really have created a piece of the future ..." - Dan Polley, Digital Engineer, Enya
The arc, ghost audio, and mtt technologies are now market-ready and can be experienced on application at Intonation's website www.intonation.ie.

What it means for the industry
For the first time:
True lossless analog quality sound can be fully realised from digital recordings
Vinyls can be printed from "uninterrupted" analog quality signal, even if originally recorded digitally
Back catalogues of digitally recorded music can be re-issued as analog sound and heard as never before
True lossless analog quality streaming can be done
True lossless analog quality music can be downloaded in small file sizes
