I know this is probably the oldest question in the book, but I still can't seem to find a conclusive answer to it.
So, in the last session where I was recording vocals, there was a significant delay when the vocalist sang her lines resulting in a horrible sort of echo effect. We managed to get round it by her basically not hearing herself in the headphones and just relying on performance, but it was far from ideal.
Just to give some details of my set-up:
Mac mini 2012- 2.3 GHz Intel Core i7, 16 GB ram
Recording onto an external drive.
The tracks are admittedly quite developed and running quite a few plug-ins, which presumably is slowing things down. Generally about 25-30 tracks, with compressor vst's etc. It's a pretty powerful Mac though, so I would have thought it could handle such things.
I tried turning the buffer size down and this did help somewhat, but didn't entirely resolve the issue.
I have another session on Monday and would like to have this sorted before we start if possible.
