[QLab] Tape Effect

[Weeks, Matthew]

I have been trying to find a way of creating an effect within Qlab that recreates what happens when you stop a sound effect that is playing from reel to reel. Is there a way of doing this ?
Instead of an abrupt or fade out stop I'm looking for a way to trigger the sound effect to slow down and then stop .
Thanks
Matt

This type of effect will need to effect 1 is your normal audio track and the other is a slow down effect you can set it up where the slow down effect follows the normal audio track to give you the effect you want I don't think QLab has that built in to it.

When I face this problem I do a super-quick (.25 seconds, usually, or thereabouts, but season to taste) fade of the sound that's "rolling" in the same cue that fires my "tail." Also a useful technique for lifting record needles, turning a car off, or any other action that has a Thing You Hear Stop Making Noise Because Of Something An Actor does.

If you are using any kind of digital board you could use QLAB to change to advance the scene on the board and insert a pitch effect, then send a midi cue to change the pitch setting.

I think Ted's suggestion is the quickest, and possibly also the best
unless you really want to slow down and pitch down from
that-exact-point in the audio. If you record a nice slowing down sound
you know exactly how it will sound and you can make something
elaborate and nice.

For another approach - how I've solved these kind of issues in the
past is to send midi messages to an external app (PD, Max,
SuperCollider) which does the things that Qlab cannot. If you dont
know any of these programs then Max or PD would probably be your best
start. In your case it would be load and play the sound in the
external app with the effects that you want, triggered from Qlab.

If you want to go down this path and need tips, Im sure I can help out
a bit, and probably others on the list too.

Count me in on that. I have experience with all the previous methods: In a current show I use a 01V that is controlled by QLab to make a pitch shift, I use the tail-method with a fast cross fade and I have over 14 years of experience with PD/Max and use that to control lots of stuff.

You have to decide for yourself how much time and effort you want to invest and how important a certain outcome is going to be. When it has to be absolutely perfect like a stopping tape: use an external program that simply slows down the pointer (like PD). When it doesn't matter if it is perfectly the same: use a downpitched excerpt of the sound source with the fast x-fade method. When you have a digital mixer you can try it with the pitch shift method.

Cheers,
Wilf
