Some sites dealing with the subject are quite specialized. This combination of classic tube technology and state-of-the-art digital equipment re-creates for compact disc the wide dynamic range, lifelike clarity, and spatial perspective of Mercury Living Presence.īecause of the historical significance of the Mercury Living Presence recordings, and in response to requests from record collectors, it was decided to use the original LP covers and liner notes whenever possible."įor those wishing to know more (much more) about Mercury recordings I highly recommend the following site. in addition to providing the exact reciprocal of the original equalization curve, the tube technology replicated the full, rich sound, clarity of instrumental timbre, and solid convincing soundstage preserved on the original tapes or film. Throughout the CD mastering process, the digital master was compared to and matched against the 3-track master to ensure as true and faithful digital reproduction as possible.įor the transfer of these masters to the digital domain, the original Mercury vacuum-tube Westrex film recorder and Ampex 3-track tape machine were restored. The actual analog-to-digital conversion device used 128 times oversampling with proprietary noise-shaping techniques. Only the original masters were used for CD transfer, and, as in the recording sessions themselves, no equalization, filtering, compression, or limiting was used.
"In bringing these historic recordings to compact disc, the aim of the production and engineering team was to capture as accurately as possible the true sound of the original tape and film masters.
