OK...
 
I remember this can be done, but it's not something I've tried before so I'm a newbie here...
 
I just transferred a recording from 1/4" tape, but it was playing at 7.5ips while the recording (I believe) was actually 3.75ips. My machine will not play that slow (7.5/15) So I'm trying to make the shift via software. I'm guessing it won't be very audiophile, but I'd like to do it anyway.
 
I've tried a few attempts and not gotten anything even close.
 
Ctrl-dragged the clip end... Changed the project tempo to half it's value with clip follows project enabled in AS...
 
I guess I could use melodyne/V-Vocal to time stretch as well as pitch shift?
 
Right now I'm transferring more in the same situation so I can't try until this final transfer is completed
 
Thanks for any clues to this procedure...
 
 

Slow down the files with Steinberg Wavelab. There is a test version that will work 14 or 30 days.
WaveLab makes the best results by slowing down tapes. It changes the pitch -1 octave and doubles the playing time with one command. The same way as a tape machine.

Audacity is a free program that has such a feature with good resolution, but no batch functionality that I can recall (you would need to do each file separately).

I've just been messing around with this and you should be able to do it right in SPlat with the loop construction.  Right click the clip and select "Groove-Clip Looping" and it will keep the pitch respectively.  You could also go into the Clip drop down and select "Loop Properties", in there you can choose the BPM you want it to follow and the reference pitch you want it to stick to

Cool. I've never noticed that feature; is it in WaveLab Elements, also?

You can do this in SONAR easily.
 
1. Slip-edit the end of the clip so it's twice as long, then bounce the clip to itself.
2. Open the clip in the Loop Construction View.
3. Choose Clip > Stretch On/Off and set the Threshold to 0 (i.e., no transient markers).
4. Change the pitch semitone parameter to -12.
 
The file will now play at half speed. Bounce the clip to itself...done. This is the same result as slowing down tape by half-speed.
 
Note: In Step 3, you do NOT want Loop On/Off enabled. This is not about looping. Also Threshold must be set to 0.

THanks Everyone!

I will explore these ideas...

I'm also now thinking it might be 1/4 the speed? (1 7/8)

Scary...

Funny as it's been so long since i played with this scenario.

This seems it might be too extreme a shift to currently be feasible.

Its recordings of a full band/orchestra so not something splicing would accomplish either. 🎶

Thanks Craig!

You posted this as i was posting my previous reply. I was certain this was the direction i was desiring to go, but never thought there were quite so many decisions. 👽

Hmmm...

Right direction, but i must be doing something wrong.

Im using a shorter recording to test the procedure. Same problem exists.

The first data in the clip has acoustic guitars one lefy and one right followed by a guitar left with vocal right.

As soon as I slip-stretch to 200%, I seem to lose the gtr/voc portion. It seems to only include the data from the first half of the clip.

What else am i missing?

Thanks! It's getting closer.

Hmmm...

Also reporting that it seems to give issue regarding the length and questions me regarding making the cip memory resident? Saying no simply cancels the procedure. Doesn't do this with shorter clips.

I have 64G RAM and nothing but a single stereo audio track and no plugins...

Anyone care to explain any of this?

Thanks

BTW I tried this with a smaller clip and it almost works. But it now sounds a little slow and low pitched. i.e. Not natural.

I tried using fewer semitone, but then it instantly goes chipmunk...

Sheesh... What for the possession of an old, home product tape recorder that plays 1-7/8 / 3.75 ips! 🎷
