-- processing new source at 192 kHz / 24-bit on my system creates glitches
-- down-converted & down-sampled new source to 96 kHz / 16-bit
-- re-assembled new source - d1t04 & d1t05
-- 3.3% fixed speed increase applied to new source. It corrects pitch mis-match due to slow speed, which slues. Flawed slow speed duration = 06m:42s:21f; new corrected & matched speed duration = 06m:30s:00f
-- dehissing applied to new source to reduce tape hiss by 6 dB
-- normalized new source levels to match old source levels
-- switched channels on new source to match old source
tracking & editing:
-- up-sampled Miller source d1t04 & d1t05 to 96 kHz
-- re-assembled Miller source - d1t04 & d1t05
-- edited the patches using X-fades
-- down-sampled to 44.1 kHz
-- re-tracked d1t04 & d1t05
-- corrected track order on all discs - prevents CD overburn on disc one
d1t04 St Stephen patched w/ new source 01:33 - 02:39 - new track length is 02:39
d1t05 It's A Sin patched w/ new source 00:00 - 01:50 - new track length is 03:51

"I was out doing yardsales recently. I had the SYF hat on and was looking for some fans for the hot Tucson summer. Got to talking with this one fella and the GD came up. He said to me after hearing about LL that he had some tapes. I asked him if he knew where they came from. He said "I cant tell ya man". I thot he meant that he " didnt know cant tell" but out he walked with a lil treasure chest of some cassettes. The cases werent pretty but the tapes were high end pro tapes. I asked him again where he got them and again he said "I cant tell you" but it seems your folks in the trading world might like them Well, i got home and found too many treasure to note. He told me they werent always on the best dubbing deck and some had been played and were at least 25 years old (some older) but he was sure that these versions were recorded by what he termed a "dear old buddy" and official channels and he had them for years and years and would like some of them to see the light of day. More to come."

|Mmmmmmmmm, good. And a bit of intrigue to boot!
|i think the patch source volume is about 1-1.2 dB too high, based on my ears (and average RMS volume values)
|Thanks to all of you for all the work you do on these torrents. I can't begin to express my gratitude to its fullest.
|I'm just a bench tech. The community well here is beautiful.
|Charlie just did a new transfer of this show on May 7th.
|Not having heard this, can anyone comment on the pitch of the patch? Speed adjustment and pitch adjustment are two different things.
|hey Monte, good choice of software :)
|spin that wheel......
|hey Charlie, I just saw your new source seeded. Several of you with decently trained ears kept saying slow, slow, slow - regarding the new source. Two of you said 3.3% slow. It's a slow dub, the way I see it. It also happens to slue against your master. Cued up, the 2 souces for St Stephen are cut 5 frames apart from each other at the top of the track. The new source, which has been sped up by 3.3%, begins 5 frames behind the Miller source. Vocals kick in at 01:33. Both sources are matched precisely in time at this point. And they are perfectly synched to each other for the entire 4 seconds of St Stephen vocals that the Miller source contains. My edit point is at the start of vocals. The sped-up new source has made up the 5 frame difference by this point. This means to me the dub is slow, and it is slueing against the Miller copy.
Pitch will always follow speed. I view this pitch problem as a tape speed problem. The source r-r deck p/b could have been slow. Or the gen 1 cassette recorder could have made a fast dub. Or the cassette dub p/b could have been slow during audio capture process.
|Actually, when you're using software to change pitch/speed, you have multiple choices: change speed and leave pitch the same, change pitch and leave speed the same, or change both in multiple ways (including simple resampling to change the speed and pitch together analogous to analog).
|I agree exactly, rbbert. I used Samplitude's time stretcher. I deployed it in hopes that it would cause the pitch to shift with it automatically - like analog. I did NOT dial in an extra pitch change. I honestly don't know if the pitch changed with the time stretch correction. I am a Newbie using Samplitude. I put up the process module JPG for everyone to see. My sense of pitch and ear training is meager. That's why I've brought this up for discussion. Maybe I should have used a few PMs first.
"Since we are a music community here, I was thinking maybe several of you have excellent pitch, or even perfect pitch. Samplitude's Pitch Shifting processor increments in half steps, at a resolution of 100ths of a half step. Somebody give us the correct number to shift up, and we're done here."
I don't see how a tape sitting in a box can go out of pitch. I am confident we have a tape speed problem. This is causing a pitch problem, just as I would expect in analog. Both should be corrected, unless there is some extra processing we don't know about. I figured Charlie was busy. Many haven't seen CM lately. So I grabbed the new tracks at LL, and took a crack at helping to fix this thing. Then I fell into my own trap. I made a bad patch. I caused a CD overburn problem for disc one. My ear training is insufficient. I enjoy giving back. This excercise is a good learning experience, and a review for the rest of us. Thanks for your valuable input.
Is the pitch on this fix correct? Most importantly, we just want to get it right. I felt I had to fix my mistakes.
|+3.3% tape speed increase synchs new source speed to old source speed
120 BPM + 3.3% = 123.96 BPM = correct speed rate to increase
according to this source, here is the math to do pitch correction vs speed correction
+5.94% increase in pitch is one half step - we need +3.3% increase in pitch to match up
3.3 / 5.54 = 55.5% of one half step pitch increase = correct pitch rate to increase
Thanks rbbert for explaining the resample function correctly. I really appreciate it. I did NOT resample. My bad. In Samplitude, I just dialed in 123.96 BPM again. I selected resample this time. It automatically set the pitch rate increase correctly to +56% of a half step. Simple.
I am hoping that in some way this will help that box of old tapes. Thanks Charlie and everyone for your patience. Peace.
|Keep up the good work Monte
