| Tech Note | Grateful Dead February 18, 1971 Capitol Theatre, Port Chester, NY SBD -> Dolby A Reel -> Dolby A decode -> DAT -> Sound Forge NR -> CD-R The Sound Forge noise reduction was used to attenuate a very narrow frequency band (in the vicinity of 8000 Hz) which was present as interference on the original reels. See my notes below for details. Disc 1 Set 1 1. Bertha (7:13) * 2. Truckin' (11:03) 3. It Hurts Me Too (7:42) 4. Loser (8:21) * 5. Greatest Story Ever Told (3:45) * > 6. Johnny B. Goode (3:39) * 7. Mama Tried (3:29) 8. Hard To Handle (8:01) Disc 2 1. Dark Star > (7:03) 2. Wharf Rat * > (7:21) Set 2 3. Dark Star > (7:14) 4. Me And My Uncle (4:04) 5. Lucky Lager Dance Time (2:39) 6. Casey Jones (6:10) 7. Playing In The Band (5:09) 8. Me And Bobby McGee (6:06) Disc 3 1. Candyman (9:46) 2. Big Boss Man (5:40) 3. Sugar Magnolia (8:29) 4. St. Stephen > (5:57) 5. Not Fade Away > (4:33) 6. Goin' Down The Road Feeling Bad > (5:01) 7. Not Fade Away (3:59) 8. Uncle John's Band (6:44) * first performance The original reels of the Port Chester run of '71 were audibly tainted due to a cable problem. The result is a tone which hovers around 8000 Hz with an amplitude of about +20 dB above the noise floor. This translate to a very annoying pitch, especially during quiet sections, which is in the old-tv-tube or lousy-hard-disk or maybe even the-sound-you-hear-after-you-slam-your-head-against-a-concrete-wall class of 'whine'. Because this interference is 'monochromatic' it's easy to get rid of if you have the processing power and a quick FFT algorithm. I used the filter-shaping capabilities of the Sonic Foundry Noise Reduction Plugin to tailor a very narrow notch filter which attenuated the interference without affecting the rest of the signal. And it's all done in the digital domain. Huzzah! As a side note, I actually ended up crafting many filters to process these shows. The frequency of the interference actually drifted anywhere from 7700 to 8100 Hz during a given show. This was probalby due to a slightly wandering reel speed. It made my work harder but when I tried a much wider filter I started to be able to hear the attenuation in the music. The filters generally go like this: 25 dB /- - - - - - - -\ / \ / \ 0 dB | | 7830 7900 7970 The end result is no more annoying whine! I also removed some of the nasty mic feedback in the 2/18/71 Bertha using this type of filter. Leigh Orf |
