i did a days worth of field recording a while back into input 1 of my H4n which is the left channel. it played back into my headphones at the time on both sides. however when i play back what i recorded that day on pro tools it only plays back in my left monitor. is there some way to get it centrally panned? thats a whole days stuff gone otherwise.
It's a bit unclear where your problem is. Do you need help in protools to get the sound in the center image? Or do you want to get a stereo image from 1 channel audio?
Protools answer: drag your files to 2 mono tracks from the stereo track. Delete panning automation on the mono tracks. Stereo image: Unless you used a stereo mic(setup) the latter is impossible. If you used channel 1 of the line input with a mono mic this is all you have unfortunately.
