Hi Gargoyle Studio. My broadband is modest - I live in a village in Southern Spain! Here’s a bit more detail about how we work…
I have Skype running on one PC which has an oldish but pro soundcard in it (Echo Gina) and I send an aux buss mix to it from my audio desk’s output which is monitoring Cubase output. I add my voice to the mix using a decent mic on a separate channel. This means that I hear Cubase output on my monitors in stereo, my mate gets mono with my voice mic mixed in.
I feed Skype’s output to my speakers - so I can hear his voice without handset or headset needed
My DAW PC is entirely separate, but has a net connection. I share my screen using Teamview.
At the other end, my mate has a good laptop with an internet dongle. he links to a pair of monitors although he sometimes uses headphones too. He sees my screen and hears the mono mix and my voice. Teamview allows him to take control, but in general, I do most of the actual manipulation. He can hear quite subtle differences in vocals which are in a foreign language to me and we use Variaudio a great deal to tighten and correct vocal performances.
I have the balance set up so that I can listen to my monitors at a comfortable level with his voice at around that of a human voice in the room. His mic is quite good, so aside from a little wooliness, it feels like he’s in the room with me. I hear a bit of spurious noise from his end - loud motorbikes in particular, but it’s not too distracting
We generally work on a project for an hour or so, then I send over an mp3 via DropBox or directly through Skype. Then we break, make notes, and go again.
This is not just an occasional thing, we have been working this way for the last few years, he used to travel over to do projects with me, but this way is much more efficient. Of course it’s important that we know how each other thinks, but the advantages are obvious. It wouldn’t suit everyone, but it works for us!
One final note, we don’t use skype video as that takes up bandwidth and occasionally the net is slow, but in general it’s trouble free.
