Process: ------------------------------------------------------------------------------- The album was cleaned on an EV-1, which is KAB Electro Acoustics’ version of the Nitty Gritty. It was transcribed on a Technics SL- 1200MK5 turntable with custom modifications by KAB Electro-Acoustics using an Audio-Technica AT150MLX cartridge with a MicroLine stylus. The preamp was a Carver C-2. Analog to digital conversion at 24-bit/96kHz was with an E-MU 0202. Recording of each disc was as a single wav image file on a Sony VAIO desktop computer with a 3.0 GHz Pentium IV processor using Cool Edit Pro 2.1 at 32-bit/96kHz, floating. Cool Edit Pro was used to remove extra "silence" at the beginning and end of each side and to drop and name cues. Some clicks were removed “manually” using Cool Edit Pro's “fill single click now” command. In anticipation of the production of an extra sample, during resampling to 16-bit/44.1kKz, each 96kHz image was trimmed to a length which is one less than a multiple of 1280 samples so that the resampled 16-bit file ends on a CD sector boundary. Each 32-bit image was saved as a 24-bit/96kHz image so it could be opened in ClickRepair. ClickRepair was used with a declick setting of 50. No other amplification, noise reduction or editing was done. QueListTool v1.7 was used to extract and save each image cue file. The cue file was used in foobar to split each image to wav tracks and then QuickSFV was used to create an md5 checksum file for the wave tracks. These wav tracks were deleted. Using the wav image cue once again in foobar, the image files were again split into tracks, and this time compressed to FLAC (level 8) and tagged. The FLACs were then decoded and checked using the checksums from the never compressed wavs. No differences were found, providing confidence that no errors occurred in encoding the Hi-Rez files to FLAC, which some claim is likely. The m3u files were created with Mp3tag. The 24-bit/96kHz wav images were resampled to 16-bit/44.1kHz in Cooled it Pro using Gaussian dithering with a bit depth of 1. The wav image cue file was converted to a wav tracks cue file using CUE Tools, which only works with 16-bit/44.1kHz files Hardware: ------------------------------------------------------------------------------- Cartridge........: Audio-Technica AT150MLX cartridge with a MicroLine stylus Turntable........: Modified Technics SL-1200MK5 from KAB Preamp...........: Carver Preamplifier C-2 Audio Adapter....: Creative Labs E-MU 0202 at 24-bit/96kHz Computer.........: Sony VAIO 3.0 GHz Pentium IV Software: ------------------------------------------------------------------------------- Audio Editor 1...: Cool Edit Pro 2.1: record as 32-bit/96kHz wav image, Drop & name track cues, save as 24-bit/96kHz & 16-bit/44.1kHz Noise Reduction..: ClickRepair 2.2 (Build 35c) Cue Extractor ...: CueListTool v1.7: Extract cue file from wav image Audio Editor 2...: foobar2000 0.9.5.1: convert wav image to FLACs and tag them Cue converter....: CUETools: convert single file cue to multiple file cue File Tagger......: mp3tag: create m3u playlist Checksums........: QuickSFV ClickRepair Log---------------------------------------------------------------- ClickRepair 2.2 build 35c : 9/7/2008 Java version 1.3.1_11 by Sun Microsystems Inc. on Windows OS start execution: 20:47:35 ---- input file: C:\_Temp\Led Zeppelin - The Song Remains the Same\Disc One 24.wav output file: C:\_Temp\Led Zeppelin - The Song Remains the Same\Disc One 24-cr- 50.wav ---- start processing: Disc One 24 time 20:49:34 settings Default LP declick 50 decrackle 0 pitch OFF Wavelet Stereo finished: Disc One 24 time 21:11:10 elapsed time 1296 sec samples: 283391999 repairs: 128796L (1/2200), 200624R (1/1413) ---- ---- finish execution: time 21:11:46 ClickRepair 2.2 build 35c : 9/7/2008 Java version 1.3.1_11 by Sun Microsystems Inc. on Windows OS start execution: 21:12:22 ---- input file: C:\_Temp\Led Zeppelin - The Song Remains the Same\Disc Two 24.wav output file: C:\_Temp\Led Zeppelin - The Song Remains the Same\Disc Two 24-cr- 50.wav ---- start processing: Disc Two 24 time 21:13:45 settings Default LP declick 50 decrackle 0 pitch OFF Wavelet Stereo finished: Disc Two 24 time 21:30:43 elapsed time 1018 sec samples: 292512050 repairs: 244308L (1/1197), 361120R (1/810) ---- finish execution: time 21:31:15
