will a headphone extension cause a delay?
I'm doing a DIY recording at my house for a 3 piece band. The problem is that everyone needs to hear the vocals, but they're going to be pretty far away for the headphones to reach from the board. If I use extension chords on the headphones, is it going to cause a delay?
Thanks for any help!

The further away you are, the more delay there will be. If you want to test it, run a click to the headphones, record the audio coming out of the headphones into a mic, and then record that to a different track on the computer. If the audio looks/sounds like it's too off, then you have a problem. If it looks/sounds fine, roll with it.

Hook it up, and have fun!!!
Howling at the neighbors. Hoping they have more mic cables.

"Propagation speed is affected by insulation, so that in an unshielded copper conductor ranges 95 to 97% that of the speed of light, while in a typical coaxial cable it is about 66% of the speed of light.[1]"

He's not asking about distance of the singer from the other players, he's talking about extension cables for headphones.Brian Dorn wrote:The further away you are, the more delay there will be.

Want the math?
The shortest delay that the human ear can detect is 20ms (0.02 sec).
It takes one nanosecond (1*10^-9 seconds) for an electron to travel 14 inches of cable.
0.000000001 seconds = 14 inches
Multiply both sides by 20,000,000
0.020 seconds = 280,000,000 inches = 23,333,333 feet = 4419 miles
In other words, for the human ear to detect the latency of an analog signal between two cables would require one cable to be 4419 miles longer than the other. In actuality you will NEVER hear the signal out of the longer cable because the capacitance/foot rating will degrade it to nothing.
I used this same math to debunk cable length delays on more than one discussion forum.

Welcome to the TOMB?!
Don't get all butt-hurt about it! Your question was pretty thoroughly answered and then people had a weenie lit bit of fun at your expense. If your post count is low you're going to get a bit of hazing on any board you go to, but I can almost guarantee that you'll get the best recording advice, the least snarkily-given, here as opposed to any other forum on the internets. YMMV, of course.
