Re: [ARSCLIST] Programmable varispeed question

Hello, Henry,

You can draw pitch curves in differing ways in both Samplitude and Diamond Cut. Samplitude permits random "speed" changes as well as straight line, DC6 has curves that you can adjust the trajectory between a start and finish speed.

I believe one person actually uses a programmable signal source to change the capstan motor speed on the playback deck...but I don't have details.

Hello all,

I'm new to the list, so please forgive me if this is a common topic of discussion. I've searched the archives, but I can't find an exact answer to this. I hope someone might be able to help.

What I need to do is varispeed a recording I have, and that varispeed needs to change gradually throughout the 5 minute piece. I think the recording was made on something which was changing speed as it recorded.

So I want the speed of the music to change as well as the pitch, i.e. I'm not looking for a system which maintains the speed while pitch shifting.

The file is already on a CD. So I'd be looking to perform this correction on a PC (preferably) or Mac (but only if I can borrow one.)

Ideally, I need something which I can set relative speed values into, and the system will gradually ramp between them to restore a constant speed and pitch. Is there any program which will allow me to play back this music with, for example, a +3% speed at the start, slowing down to -1% at 4 mins, and then finally -2% at 5 mins?

Thanks for your help,

Henry Clark
