I find that the decoded version of "ONJ-Take Me Home Country Roads" has the chorus sounding much cleaner (less harsh sounding) and clearly defined. When her voice kicks in it is a little softer and purer sounding , with noticeably improved separation between elements for the rest of the track. This version sees me wanting to hear the whole track.

sandyk Posted September 10, 2019 Share Posted September 10, 2019 From Wiki : Quote Dolby A Dolby A was the company's first noise reduction system, presented in 1965.[1] It was intended for use in professional recording studios, where it became commonplace, gaining widespread acceptance at the same time that multitrack recording became standard. The input signal is split into frequency bands by four filters with 12 dB per octave slopes, with cutoff frequencies (3 dB down points) as follows: high–pass at 80 Hz; band–pass from 80 Hz to 3 kHz; a low–pass from 3 kHz; and another low–pass at 9 kHz. (The stacking of contributions from the two low-pass bands allows greater noise reduction in the upper frequencies.) The compander circuit has a threshold of -40 dB, with a ratio of 2:1 for a compression/expansion of 10 dB. This provides about 10 dB of noise reduction increasing to a possible 15 dB at 15 kHz, according to articles written by Ray Dolby in JAES (October 1967) and Audio (June/July 1968). As with the "B" system, correct matching of the compression and expansion processes is important. The calibration of the expansion (decoding) unit for magnetic tape uses a flux level of 185 nWb/m, which is the level used on industry calibration tapes such as those from Ampex; this is set to 0 VU on the tape recorder playback and to Dolby Level on the noise reduction unit. In the record (compression or encoding) mode a characteristic tone (Dolby Tone) generated inside the noise reduction unit is set to 0 VU on the tape recorder and to 185 nWb/m on the tape. Dolby A also saw some use as the method of noise reduction in optical sound for motion pictures.

Unfortunately, there is a little problem here ... the Pink Panther movie, along with the Mancini theme music, came out in 1963; but Dolby A was only announced in 1965, as a product - are we witnessing a "Back to the Future" moment here, where the distributed version of the recording was contaminated with the Dolby A virus in some mysterious way, . There were a plenty of opportunities for that to happen, because Audio CDs were not released until 17 years later in 1982 . It may have even been possible for the soundtrack to have come from the audio of the 35mm (?) film's soundtrack and been recorded to magnetic tape for the CD's release ???

sandyk Posted September 16, 2019 Share Posted September 16, 2019 The simple fact remains that although the differences between the original files and the latest versions will be obvious to most people, the numerous small increments made by John along the way could not have possibly been discerned reliably using the output from a Laptop's tiny speakers and it's mediocre audio system by Frank . There have been numerous different versions along the way from John, that most of you have not had access to. I have had some earlier Abba samples from John that go back as far as 16/03 /2019. John has worked to a very tight schedule for many months with this project, using mainly Abba, because it was the most challenging of all the incorrectly decoded Dolby A recordings.
