Daily logs...
Day 1 (2.5 hours)
Tests:
I tested noise reduction on multiple bits of multiple tracks to test out the feasibility of this project. It looks very good! I tried various NR levels, from 50 down to 1. It takes a long time for my poor little 486 to process this.... this project will take significantly longer than i had anticipated. Summer is coming on strong now as well. Working in the Attic cannot be good for the record. I'm going to only work on this late at night when it is actulally cool out... less possible damage to the LP!
Track B3: The Light Sailer 2:32
I figured I'd try the noise reduction on a full track, just to see how the process will work. I wanted one I wouldn't mind listening to a lot. ;) This is a quite loud track, so i figured it'd work well. The NR Filter takes about 23 minutes each time on the track. I "normalized" the track, then ran the NR, then normalized it again. I used NR at level 3. (after trying 50, 10, 5 and 1). It sounds AMAZING!

Day 2 (2 Hours)
Track A1: Creation Of Tron 0:45
I figured I'd start at the begining... Since this is the first track of the album, it's a little more hammered than the others on the LP. Unortunately, it starts out very quiet as well. It's a bit crackly after the noise reduction (level 3). I might mix in the beginning bit from the chapter on the special edition with the extra prologue, so the mastered track will have a nice quiet extended intro. I've run the NR filter on the track about 3 times at 12 minutes each. I've ultimately decided to save this track out with no noise reduction, and i'll deal with it when i master the tracks from the LD.
Track A3: We've Got Company 2:15
I'm going to skip over the Journey track for now. I'll work through the remaining tracks in order. This one took 30 minutes to run the NR filter over. Unfortunately, this track is quite worn as well. I noticed it about 1:30 into the track, some of the strings are distorted a little in the right channel. :(


Day 3 (1.5 Hours)
Test CD:
This cd was going to be multi-purpose. It was going to be a mixed-mode CD. First a few audio tracks that were half-done from my hard-drive, and then the same tracks as CD-ROM data. I got a little too ambitious with putting data on the cd, and screwed it up. I was able to recover the media, but I could then only put one session on the end -- data only. So, this CD is a backup of the 242mb of songs from my hard drive. Oh well. At least I can clear off those files now! I'm contemplating buying some more media and making the mixed-mode cd i wanted, but there's really no need to do so, more than novelty value at this point.


Day 4 (4.5 Hours)
Track A4: Wormhole 2:21
No problems. Sounds very similar (noisewise) to A3. 2 minutes to normalize, 34 minutes to Noise-Reduce on level 3. Some pops removed by hand. Quite a noisy track (right channel scrapes). Digital artifacts are defintely evident in the background unfortunately. Also, there are these annoying scrapes in the right channel that sound like a CD that's dying... ugh. Oh well.
Track A5: Ring Game & Escape 2:53
Seems to be in better sshape than A4 above, although it may be because how i cleaned the record. I've also put the dust cover back on the turntable. It seems to have worked really nicely. Perhaps a lot of the noise at the end of A4 was due to dust settling on the record while it was playing.... could be... I may re-do the above track, and reduce the NR level as well. 2:30 to normalize. NR level 1: 44 minutes to process. The Drum roll in the beginning sounded odd, so i'm trying changing the parameters of the NR filter. (FFT size of 8192, not 4096, and Precision factor 11 instead of 8) 10 NR Tests at different levels at 5 minutes a piece... (on a 12 second sample) After the amazing results from these tests, I know I'm going to re-process the previous track. I wish i had the HD space to store the raw samples along with the resultant samples... but, as noted above, I already had to purge the drive out to a CD... The new settings don't cut down on the 60hz hum as much, but they do take out a lot more static, and do it more cleanly... The final NR process took an additional 55 minutes)
It's amazing what reading a little documentation will do!


Day 5 (1.5 Hours)
Track A7: Tron Scherzo 1:47
I adjusted the head on the turntable arm, and voila, hum gone! Ran the same NR levels as above -- 34 minutes. Volume was at a good level, so i didn't normalize it. well, okay... i forgot to, but it doesn't need it anyway... Removed 3 pops by hand..


Day 6 (2 Hours)
Track A3: We've Got Company 2:15
Re-sampled & re-NR'd. (40 minutes to NR). Sounds quite nice. There are some of the usual scraping sounds (primarilly in the right channel, as usual), but overall it sounds beautious!
Track B5: A New Tron & The MCP 5:45
I figured I'd start this one... Digitize it, then start the NR, and go to sleep. About 2 minutes in, it skipped a groove! Yow! Okay, so then i figured i'd scrap it for now, and work on...
Track B4: Sea Of Simulation 3:20
Which had the same problem. So i just saved it out & figured i'd work on it later. Then I went to sleep.
I think I'm going to end up sampling the audio tape of the soundtrack i've got, and mix the two together... as seamlessly as possible..


Day 7 (4 Hours)
Track B4: Sea Of Simulation 3:20
re-cleaned album, and it sounds okay... so i kept the new section from 1:11 to 1:21, and the rest of the track is from last night's sample. It's seamless. I zoomed in to specific parts of the same note, (the same waveform) and clipped out the repeating part. Trust me, it sounds great. Luckilly, neither were normalized or NR'd when i did this... 3 minutes to normalize, 1 hour, 4 minutes to NR
Track A4: Wormhole 2:21
re-made this track which had way too many artifacts in the older version. No issues. 3 minutes to normalize, 46 minutes to NR.
Track A6: Water Music & Tronaction 2:36
sampled 3 times: time 1, there was a slight pop in the beginning. Times 2&3: that pop became a skip. First sample used. I'm trying out a slightly stronger NR, since the beginning is so quiet... two 3 second sections at 1 minute to process apiece. 3 minutes to normalize, 46 minutes to process at NR level 3.


Day 8 (5.5 Hours)
Track A7: Tron Scherzo 1:47
I accidently mangled the finished version of this last night. I cleaned up the beginning, then started to try more NR in a section of the middle, but cancelled it. I thought it would undo the modified section, but it didn't. I saved it out mangled before I realized that it was mangled. So i'm re-doing it. No issues. 4 minutes to normalize, 36 minutes to NR
Note: I was confused as to where the Light Cycle music fits into the soundtrack. I assumed it was after "Ring Game & Escape" (A5), but actually, it goes IN A5. The order of the music in the movie is: Ring Game, Light Cycle Game, Escape. Unfortunately, the movie only had the Light Cycle Game music, and ended it right before the Escape music, so i'll have to use the escape music i already have. I will split A5 into 2 tracks, and place the Light Cycle Game between them. (I could keep to the original soundtrack's order, and place the new track immediately after A5, but i feel this is how the soundtrack would have been made if the light cycle music was released in '82.
Note: After listening to A5 again, i've come to realize that I'd better not modify it. I'll just put the Light Cycle Game music either before A5 or after A5.
Track A7: Tron Scherzo 1:47
AAARRGGH! I listened to the first version i sampled, and it was so much crisper than the new version, so i tried to re-sample the new part, and mix it back in. I was very unsucessful. I couldn't get the volume and noise level consistant. So, after 1 hour of messing with it, i just clipped a little from right after the screw up, and pasted it right over the screwup. There's a little flutter like sound, but i'm sure i'm the only one who'll ever hear it. ugh.
Track A8: Miracle & Magician 2:36
Sounds adequate. 3 minutes to normalize, 1 hour to NR Precision factor bumped to 13 for no apparent reason. Smoothing back down to 1. FFT still at 8192 points
Track A9: Magic Landings 3:40
Track sounds nice. very clean. There was a skip in it the first time i sampled it, but the second time, it was just a pop. I removed it by hand, and did some NR tests. It seems like the NR settings i'm using don't do anything at all. Normalize takes 4 minutes, NR tests take 10 minutes, NR process take 57 minutes.


Day 9 (4 Hours)
Tracks A1,A10,B1,B2,B6
Sampled all of these tracks, and normalized each of them. Avverage time for normalization is about 4 minutes. No issues with these tracks. I did occasionally clean up a pop here and there by hand.
Track B5: A New Tron & The MCP 5:27
I honestly thought this was going to be hell. The track had an overwhelming scraping sound throughout the track. It also had 3 skips. It was horrid. I tried cleaning it dry twice... no effect. Then i tried using a little of the cleaning fluid. It had a little effect. Then I doused the track in the cleaning fluid... cleaned it right up. I might re-do one of the tracks i've done in the past... i need to listen through them again. (and here i was, with an x-acto knife with a clean blade, ready to do surgery on the track... thank the gods i didn't have to do it!)
Tracks A2 & A11 (the songs by Journey)
After listening to A11 for the first time ever, i decided to sample it, and the other Journey track. I'll put them on the end of the disk. Track A11 (1990's Theme) is kinda neat...
At this point, all sampling from the LP is done. Once i listen through all the currently recorded tracks, I'll know what i should re-sample. Now just the Light cycle game, and the ending titles are left. (Laserdisc tracks)


Day 10 (1 Hour)
Backup CD
I just burned a cd with all of the tracks in their current state. I have yet to resample the bad ones (A3, A4, A7, A8), and the remaining Laserdisc tracks (B7 & LightCycles). Once all the tracks sampled last night have been NR'd the very little bit that they need, and these other six tracks have been resampled, normalized, and NR'd, i'll be done... Not really much work, but the NR will take a very long time to perform. (approx 1 hour per every 3 minutes). (Not to mention hand-editing to remove simple pops.)


Day 11 (2 Hours)
Tracks A3,A4,A7,A8
I resampled these tracks & normalized them. I would have done more, but I forgot the new NR settings at work. The new NR settings will not get rid of all of the light crackles, (which have been minimized quite a bit though the new method of cleaning the record) but it will cut down on the hiss and the hum (increasing S/N ratio a lot!) without decimating the sound tonality. tonality.. wow. cool word.

The new NR settings are:
  • NR Level: 4
  • FFT Size: 8192 points
  • Precision Facrot: 7
  • Smoothing Amount: 3
  • Transition Width: 0 db
I know these are useless to everyone, but it's mainly here for my own reference...


Day 12 (8 Hours)
Tracks A01,A02,A10,A11,B01,B02,B06,B05
I processed the Noise Reduction for these on my P75 at work in the background of using VI, compilers, etc. It took significantly less time than my 486. (a 2 minute section on the 486 took about 40 minutes, whereas it only took 15 or so on the P75.)
On the Journey tracks, I cheated a little. I only applied NR to the beginning (A11) and ends (A02, A11) of the tracks to reduce processing time. You can't tell in the middle of the song anyway...
Track: IO Tower Music (from Arcade Game)
I just adjusted the volume on this one to put it on par with the other tracks. It used to be way too loud.
Track: Light Cycle Music & Ending Titles
Sampled these off of my Laserdisc, and normalized them to only 95% (rather than the 100% of the other tracks) as i am not applying any NR to them. There is a significant amount of hiss, but the NR will not eliminate it. I had to edit the tracks by hand to get rid of missing .005 second time bits... ugh.


Day 13 (3 Hours)
Track B04
Did noise reduction on this, the final track.
Backup CD (45 minutes)
Backup CD of the final versions of all tracks, along with the 4 tracks, resampled since the last CD burn. This CD will be used to restore the CD burner in the future if i make more copies of the soundtrack.
Audio CD (45 minutes)
Yes! Rev 1.0 of the soundtrack. This cd will be used to be sure that all tracks sound good. If all is well, all other cds will be clones of this one. (52 minutes of audio) WH00!
