Remasterização de disco de Elis Regina é 'restauração' que usou 'muita tecnologia'

·26 min·2 clips

Elis Regina's brother Rogério kept a secret 16-channel TV recording, and producer Max Pierre erased the original instruments in 1984 to re-record them — without Elis knowing.

1. CBN's Saturday music segment features João Marcelo Bôscoli discussing the 2026 remastering of Elis Regina's 1973 self-titled album. 2. Bôscoli is Elis Regina's son, a professional music producer and weekly CBN commentator; he has led five major Elis remastering projects since first releasing a restoration in 2004. 3. The episode's core question is what remastering and restoration can recover from physically degraded recordings, and what new technology has made possible since the first project in 2003. 4. The 1973 album was considered by Elis a sonic failure: she routinely said before studio playback, 'Let's listen to it one last time before ruining everything,' because she knew the final cut would strip the sound she had approved in the studio. 5. Brazil's 1970s oil crisis forced vinyl manufacturers to use thinner, lower-grade PVC, making the needle unstable over deep bass grooves — engineers had to cut frequencies heavily even for top-priority artists like Elis at Polygram under André Midani. 6. The 1973 album is proportionally one of the most degraded of all Elis albums Bôscoli has worked on, making it the most dramatic showcase for restoration. 7. The remastering pipeline uses Cedar's AI-powered noise-reduction software — formerly a $100,000 hardware suite used in forensic investigations and court proceedings — now available as accessible software incorporating machine learning. 8. Bôscoli explains that AI tools like Moises can now separate individual channels from a mono stereo mix, enabling remixing of recordings whose original multi-track tapes were lost. 9. In a live on-air demo, host Leandro plays the original 1973 recording of 'Com Esse Que Eu Vou' followed by the remaster, and immediately identifies a guitar previously buried by tape noise and frequency cuts. 10. Bôscoli notes that original versions remain available on streaming platforms alongside the remasters, and listeners can choose whichever they prefer — unlike painting restoration, the original 'frame' is preserved. 11. He mentions that the Elis e Tom album (remastered in 2004) was found to have a slightly incorrect rotation — one portion recorded in São Paulo ran slightly faster than the Los Angeles sessions — which was corrected in the remaster. 12. Bôscoli reveals that some earlier Elis albums were digitized directly from vinyl rather than from tapes, meaning streaming versions sometimes contain audible clicks and crackle. 13. Future restoration plans include the albums from 1971, 1970, 1969, 1968, 1967, 1966, and 1965 (Samba Eu Canto Assim), with Universal searching for tapes whose location is known but whose physical condition requires careful oven-drying before a single playback. 14. Bôscoli describes the existential risk of master tape restoration: some tapes, once baked at 60 degrees Celsius to stabilize the degraded binder, can be played exactly once before disintegrating — a single failed copy means permanent loss. 15. A posthumous Elis album released in 2024 uses a 16-channel TV recording preserved by Elis's brother Rogério; in 1984, producer Max Pierre erased the original instruments and re-recorded them with post-1983 synthesizers Elis never knew. 16. Bôscoli describes the moral weight of releasing this album as a 'declaration of love,' noting that the nearly unanimous positive reception gave him confidence to continue the project for a Mother's Day 2026 release. 17. The Mother's Day release uses only instruments from 1976 (the year of the recording), including Luizão Maia's actual bass — Elis's favorite bassist and friend — played by Robinho, recorded on the same studio equipment that originally captured Elis's voice. 18. The episode is conversational and technically fluent, with Bôscoli balancing anecdote (personal memories of Elis at home) with engineering detail (Cedar, Moises, vinyl groove physics); the host Leandro plays audio examples live. 19. The episode is best suited to Brazilian music lovers, audio engineers, and fans of Elis Regina who want both the emotional family story and the technical detail. 20. Listeners with no prior knowledge of Elis Regina or Brazilian music history may find the episode engaging but will miss many of the cultural references and the emotional weight of family archive stewardship.
