and David Bromberg sessions, April/May 1992, Dan Mc Remastering Notes:, Concatenated all the files in order, ran a multi-filter (#1 below), re-marked the tracks, cut, the tracks, eliminated a few brief spots where there were sounds of a tape recorder, starting and stopping, then re-normalized the gain (to 0 dB)., 1) Within a multi-filter (so that quantization errors are kept to a minimum):, Overall levels lowered by 4.0 dB, Eliminated hum at 100, 200 & 300 Hz, Sampled a silent section for noise and reduced sampled noise frequencies by 7 dB, Expanded hi & mid-highs at -60 dB on up, Expanded mid range at -50 on up, Expanded bass at -40 on up, Added 8db over 3.5 kHz with attack at 25 ms and release at 100 ms, Used a paragraphic equalizer (u-shaped) to increase treble and bass slightly, 2) Re-normalized to 0 dB, Here's the technical explanation of why it was most likely Europe in one of its generations, in case, anyone is interested (from an audio engineer):, "The dub or recording was made in a country where the power line frequency was 50 Hz. The tape recorder had, a full wave rectifier producing a doubling of the line frequency in terms of the fundamental ripple component, on the DC Power supply rail of the recorder, some of which got through to the recording head. For example, 50 Hz, 230 Volts is the standard line Frequency and Voltage in Europe.",
