Pitch shifting
« on: December 12, 2003, 11:57:14 am »

Can anyone tell me if Media Jukebox V8 is capable of down shifting the pitch of a .wav file by an octive?  

I have some 16 RPM records which I wish to transfer to CD's.  My current turntable rotates at 33 RPM.  If I recorded a track at 33 rpm and down shifted the pitch by one octive, the audio should sound normal.  

How can I do this with Media Jukebox 8

Regards, Paul.

I don't think there is a way to speedup/slowdown playback in Media Editor (component of MJ)...unless there is a WinAmp DSP that can do this. Seems to me that just halving the playback speed (via Sound Recorder that is included in Windows) should do the trick. The path is Sound Recorder>Effects>Decrease Speed.

Playing these audio files with a different speed makes them sound right but will not convert them to the right speed for creating a cd.
Try Steinberg Wavelab, the lite version is for free and ships with Terratec and Soundblaster audio cards (2 years ago).
Works ok for me.

"The 16 rpm record (or 16 3/4 rpm to be strictly correct) appeared in Germany, and later in the US, towards the mid-1950s. It was used primarily for "talking books", to take advantage of the increased playing time -- almost double that of a 33 1/3 long playing record. " 16.75 rpm
33.3 rpm

"Recordings at 16 rpm were widely distributed by the US government in its "Talking Books for the Blind" programme. Their fidelity was about the same as a telephone, 300 to 3000 hertz, but [have] become obsolete since the development of cassette tapes." 16 rpm

"The 16 rpm discs were never common, but I remember a recording of some of Churchill's wartime speeches at this speed." 16 rpm

"I still have a prewar 16 rpm record. It's of a speech by Lenin about land ownership and the distribution of food on a Nardoni Diskotéka label made in Czechoslovakia." [I assume the author meant "Narodni Diskotéka".] 16 rpm

Sound Recorder will save modified files...so they are CD ready.

Someone asked "what is on the 16.75 records?"  I have 4 Talking Books albums: Tales and Poems of EA Poe, Tom Sawyer, Alice in Wonderland, and Treasure Island.  These were produced by The Audio Book Company of St. Joseph, Michigan, which, I believe has gone belly up.  They are dated 1958.

I discovered that Roxio's EZ Creator, V5 has Pitch Shifting and can shift + or - one octive in 12 half-tone steps.  I produced a file shifted one octive low, but, because of some computer hardware problems (which hopefully will be fixed next Monday) I have not been able to try burning and replaying a CD to see if all is OK.  I'll post a note when that experiment is complete.
