Recording through a Macbook Pro and outputing with a delay
by Adrian Baxter on Feb 1, 2011 at 1:51:43 pm
I've been asked if it is possible to record with a regular dictaphone through a new Macbook Pro with Logic Pro 8, adding a delay of 30 seconds then having it output to speakers. Does anyone know if this is possible and how the person in question would go about doing this?
If there's any free/alternative approaches to this I'd like to hear those too.

Yes you can do this. I assume you want to use the dictaphone as a lo-Fi pre amp and mic to input voice for Logic to process, then for that sound to play back 30 seconds later as an output from logic. Sounds like something for a live theatre performance?
Important: if you doing this night after night to a packed house high ticket sales broadway etc then get yourself a dedicated solid state effects line like a boss pedal that can handle 30secs delay and input your dictophone to that instead of a software solution.
BUT: there is so much more you can do with the logic set up!!!
SO: you need to plug the minijack from the dictophone into the in on your MacBook (adjust this if u have some other set up) and set logic to use that as its recording input. This is basic stuff u should have no problem setting that up.
Then you need to make an audio object, select new the choose audio then choose mono then choose the input you have the dictaphone connected to then choose output main (your default stereo output)
Now put that audio object into IN mode using the I button to the left of the record icon.
Go into record and make a test recording. You will hear the metronome, turn it off! Stop recording. Make sure you can hear the recording then delete it.
Because the IN is selected you will now be monitoring through the channel so any input in the dictaphone will play through the speakers or headphones via logic.
So now all you need to do is to add some delay to the audio object. Put in a mono delay. Turn off all feedback. Set it to the longest delay you can. Remove any eq settings. Set balance to 100% delay. Note delay time in seconds. Copy this setting.
Calculate how many of these will add up to a delay of 30secs and add more mono delay instances after this one. Paste the settings in each time. Alter the delay time of the last one to make the exact time you need.
That should work.
If you want to simulate the dictophone then you can do that too before the first delay... So you will need to move them all down a slot or two.
