Re: Tracking with Buffersize 32?

Thanks sir The only reason I asked is because I was only getting 1 sample of RTL through the hardware and thought it was strange. No issues on my end but I just needed to understand why. I will look more into it when I free up early next week.

This stuff has been covered in multiple other threads... that's not a criticism of you, the amount of confusion out there and repeated on DUC means it's impossible to find stuff and the confusion keeps getting repeated. If I can find a thread I'm thinking of I'll link it here, but I can't even find that now. Quote:

Again the quick way I would measure conversion RTL in Pro Tools is to use an HW insert with ADC turned off. ... that bypasses both ADC and the automatic track input and output latency correction that you otherwise can't bypass. All the comments LDS made are great. The RTL utility is very handy, doing external measurement of RTL with another interface is great to do. Sometimes doing free acoustic measurements with a mic and understanding all the delay components is useful. [and related to this my own developer interest is in some area of CoreAudio internals, I have utilities that report on all of a driver's latency metrics (like RTL Utility also does but you have to step it though doing stuff) and other utilities for reporting CoreAudio driver versions for all types of drivers ... frustrating that is not obvious/simple to do. If there are folks interested in similar things I'd love to talk offline] Last edited by Darryl Ramm; 09-08-2023 at 05:50 PM. |

Sorry. That one got away from me.

Re: Tracking with Buffersize 32?
The latenty here is awful, it took 6 months for that to come back around ¯\_(ツ)_/¯

Re: Tracking with Buffersize 32?
I was just observing and didn't mean to make a stink.

Re: Tracking with Buffersize 32?
Okay, can we get back to the topic?
My stance is that buffersize does not matter until it is too high regarding total latency. What ultimately matters is latency between mic and cans, and buffersize is only one part of it. Just simply having "superfast" TDM AD/DA conversion is 3.13ms with zero plugins used. Add 256 buffer is extra 2.67ms if you use native plugins. Totaling 5.80ms as a totally normal TDM session of the yesteryear when it was superfast. Using TDM plugins also add to the number but since we are talking about native buffer, let's assume there are none. I have posted in many threads that earliest digital pianos had a latency of about 10ms from keypress to sound out, but pianists didn't have a problem with it. How much above 10ms is acceptable? That is personal. But this wanting to track at 32/16/8/4/2/1 buffer beats me. Bragging rights, I say. By definition digital systems always must have at least 1 sample buffer and the lower the buffer the higher the cost. Better stay where it is acceptable. Ultimately artist decides what is acceptable. I know some who can only monitor with analog signal chain. Vast majority accept the "about 10ms" latency, but some want to take one can off ears. Only few complain and even then I find out I have used a plugin that introduces extra latency and removing that fixes the situation. But I am biased, I mostly do FOH + monitors on live gig. Maybe the pressure is bigger in studio.
