Re: Delay compensation bug after Pro Tools update.
Exactly. I reported this bug to AVID about 3 years ago.

Re: Delay compensation bug after Pro Tools update.
Hi
Who are you replying "Exactly" to? If me/you were seeing disk I/O buffer size related issues... Do you have a bug number? Case number? What description you sent to Avid support? Did disabling LLM or disable "Allow Sends to persist during LLM" change the behavior? Would be great either way to confirm this is or is not related to the other LLM/sends issue(s). |

Re: Delay compensation bug after Pro Tools update.
Thank you Darryl.
I am running an HDX system, so I don't have the option to turn on LLM. You are correct in that I am running 48k sessions and the H/W buffer is set to 1024 samples. I will keep playing with this and report back. Randall Quote:

Re: Delay compensation bug after Pro Tools update.

To be clear the bug I am talking about causes incorrect delay compensation offsets based on the disk IO buffer not the HW buffer size. Pro Tools has two different buffers, aka split buffers. The disk IO buffer is the high latency buffer used for playback only and you cannot directly control its size. At 44.1kHz [edit:] and 48kHz it is 1024 samples. If you change the HW buffer size to a small value and the delay you are seeing does not change then it’s possible your problem is related to these other ones I mentioned. If it reduces with the HW buffer size it is likely not related. I don’t want to waste your time, but that quick test might still be interesting. I know HDX does not have LLM, it was what happens when the hybrid engine I was not clear on. It seemed at least in principle could support LLM. Last edited by Darryl Ramm; 01-13-2023 at 11:03 AM. |
