Hi all,
Many years ago before retiring I was a professional photographer and part time DJ on a local radio station in Bath.

Then I had loads of gear, but managed to do all my mixing and editing on 'SOUND FORGE 5' which I found amazing and simple to use.

A couple of local hypnotherapist guys would ask me to produce their subliminal tapes for them individually made for each of their clients.

This I would be able to do on Sound Forge 5 with no problem.

I have just been contacted again by one of the guys to produce a few more, but it is now 15 years since I last did this and have forgotten how to compress the files down to a blip so that they become subliminal and are hidden behind a piano music track.

I am still using Sound Forge 5 as I have had no need to upgrade.

Can anyone just give me a gentle reminder on how to compress the files, I'm sure that as soon as I start reading any replies it will all come flying back.

Thank you for your time in reading this and hopefully someone a lot cleverer than me will help me out.
Gerry, in S,Italy.

There is a technique called ducking where you use a compressor sidechain to control volume relative to another signal.

Or is there some sort of encoding you're looking for?

Hi
Thanks for your reply.

Perhaps I used the word COMPRESS because I mean that I used to pick the small sound bites - files and just make them smaller. For example, if the original word or small sentence was, say, an INCH long, I would reduce it so that it was about one eight of an inch so that if you heard it on its own it would just be a small BLIP sound, almost like a sound fault.

This would then be dropped into a piano recital background in a repeating loop to reinforce the therapists message.

Subliminal messaging.

I was pretty sure that somewhere I had a few reject copies and have looked, and cannot find them. Having moved, not just house, but countries I'm still not sure what I might have lost.

And that is all I need to do. Pick a small word or sentence, reduce in size and volume, select and drop into a background music track. I'm pretty sure that is how I used to do it.

Thanks for your interest, really appreciated.

The only way I could think of to do this in SF would be through the Time Stretch command.

As an example, this is what you hear at the end of car dealer's advertisements - where they read a legal disclaimer and then speed up the file so that it's barely legible. In theory, I suppose you could manipulate a 10 second audio soundbite to play in 5 seconds, preserving the pitch but changing the duration, but I don't know that you could reduce it to a "blip". It's not something I've ever tried.

If it would work, your command would be Process/Time Stretch.
