Looking for software to fix Pitch- whole song (stereo)

I'm looking for software for a pc preferably to edit the pitch of some old recordings.

These were probably transfered from a 78 to cd and are in the wrong key. Less than a 1/2 in many cases I'm told.

thanks

Blake,

Software pitch shifters are usually
not very 'audibly transparent'...

Especially if you want to change just the pitch,
but not the 'playback speed'...

Varispeed on a tape machine usually sounds very good,
but that always changes the speed and the length of the track...

If you don't mind the speed/length changing, then
rent/borrow/purchase a decent stereo tape deck...

In a similar approach, I've got a TASCAM CD player that
has a varispeed feature (on the analogue outs only)...

For 1/2- or whole-step changes, it sounds great...

Good luck,

This should be very easy, because you actually don't need digital timestretching (which is what introduces those ugly artifacts).

You just need simple vari-speed pitch shifting. I would do this in Cubase SX with the pitch shift function - but disable time stretch and disable formant correction. This achieves exactly the same as changing the sample rate - which is also a function in SX you can use. The difference is that by using the pitch shifter, you can specify how many semitones or cents you want to shift.

I believe Reaper is a new 64 bit freeware DAW that has varispeed built in.

Further clarification ...

Assuming your 78 rpm record was played back and digitised at, say 79rpm ... everything would be shifted up. The pitch is raised, the time is shortened, and the formants of the instruments and vocals are also shifted up.

So all you need to do is play the wavefile back slower. This will automatically correct the time and the formants, so you don't need these to be "corrected".

Digital timestretching and formant correction are useful if you want to stretch audio to fit a loop bpm or other stuff like that - it's more destructive.

With Cubase, I've experimented with extreme pitch changes, and then reversing them, and the files don't degrade much, if any. That isn't the case with the time stretching alogorithmns - I hate to hear even a semitone shift with timestretching enabled.

If they are old recordings, and/or from another country, they may not have referenced to A-440. I seem to recall that in Europe or at least Britain, they were still tuning to A-435 in the 60's, and playing along with remastered Beatle CD's some years ago confirmed that, if I remember correctly. Going back furthur in time the standard was even lower.

Melodyne is great if you need timestretching as well as pitchshifting. This application doesn't require timestretching - just simple pitchshifting.

I wouldn't be so sure about the Beatles using A=435 ... it's possible, but they also varisped tapes all over the show for effect.
