Check my math? [message #105053] |

Hi folks - latency's a hot issue for many PARISians, so I put a little latency explainer up on the Wiki. If any folks with relevant expertise want to run their eye over it and make sure I'm not totally out to lunch on what I've written (particularly the math) I'd be grateful for any corrections.

"That's as good as it gets in my experience. Analog input to channel with compressor and EQ to
stereo bus to monitor out in 1.5ms at 44.1KHz is incredible. And I do think it matters. All
over the internet, I hear Native DAW owners yakking about "8ms latency is just the same as
being 8 feet from the speakers", etc. No, it's not. Not if you're wearing headphones as in the
majority of recording, certainly singing, not to mention drumming. Not that timing really
matters for drumming or anything.
I talk to pro drummers who absolutely DREAD going to project studios with "low latency" Native
rigs. No fun at all. Of course, the together types will monitor through a digital console
(still with more latency than Paris) and resolve the issue that way. But how much $$$ have you
saved and complexity have you gained by having to own a console just to monitor properly for
ODs?
The comb filter effect introduced into headphones by larger latencies is a big factor in the
way a singer feels about the sound of their own voice in the cans, IMO. Higher latencies create
enough lag between bone conduction and what's hitting the ears from the cue feed to create
issues for many singers, including pitch. Many variables here, but latency does not help
anything."

By my math, here's a sample delay chart (for 44.1 kHz). Remember that sound travels about 1 foot per millisecond, which can also give you an equivalent sonic reference point (e.g. would you worry about the timing of a track that you mic'd an extra 2 feet back from the performer?). Anyways, here's the chart (please note that these values rounded off to 2 decimal places):

Latency is such a hot-button issue - how much latency is "acceptable" is going to vary from player to player, and often style to style. Small amounts bug me during tracking.
I want to get "hard numbers" for the rountrip latency of ProTools HD in there - anyone got exact data?
