Re: Tracking with Buffersize 32?
^ I use in-ears on stage. More specifically Shure PSM1000's (4 stereo or 8 mono) and PSM900's (another 4 stereo or 8 mono). Due to PT send limit of 10 I try to get some of the band members share a channel, but sometimes I need some... umh... advanced routing. But that is another story.
Mind you, that super fast PSM1000 has wireless latency of 0.37ms, or 18 samples at 48k. Add 2.9ms (139 samples at 48k) from Shure ULX-D wireless mic and it sums 157 samples of wireless roundtrip latency you would experience with otherwise full-analog monitoring. How can they perform if 64 is too slow?

Re: Tracking with Buffersize 32?
If you are going to do it, do it well. So as a community service announcement: A friend got me hooked on popcorn popped in Avocado oil with parmesan cheese grated on top. Quality Avocado oil adds a great flavor and has a very high smoke-point.

Ya man. I can record trouble free on my Mac Studio Max with the buffer set to 32 but 64 works great as well. You seem to be on the right path by not trying to record with the buffer at 256. It's not a very smart move at all.

Re: Tracking with Buffersize 32?
If an engineer reports that they've had musicians/VO complain about specific buffer sizes then that's not debatable via science, it's a real world problem. What typically happens in these arguments is we discover that some other element is adding latency -- might be digital, might be analog, might be both. I do wish more effort was spent on discovering the discrepancies instead of arguing about the science, and that "feel" was allowed into the discussion. I understand that tests have shown that human ears don't respond to latencies below a certain time, but I've also had drummers who've identified latencies my own ears couldn't possibly have. They feel it -- I'm only listening. The same is true with singing/VO, when your jawbones vibrate around the ears but the sound returning via headphones/monitors is even the slightest bit later. The brain calls foul even if the scientific test wouldn't have.
More specific to the question, I do have 32 as an option but when recording myself I rarely *need* anything under 128. Occasionally 64. |

The devil is really in the detail though. The problem with DSP in 2023 is that most DAWs now offer dual sample buffers for recording and playback as standard. If you use as 64 sample buffer natively in Pro Tools, that doesn't actually mean your playback channels are using a 64 sample buffer too. That is the benefit of playback channels! You can buffer them extensively before playback actually starts. When it comes to latency, round trip latency is the only thing that actually matters. The native sample buffer is only one aspect of round trip latency. Some food for thought: - the difference between 32 and 64 sample native buffers is 64 samples of latency. - HD I/O have an AD/DA calculated latency of 50 samples. - Lynx Auroras are 25 samples. - RME are 14 samples. - A HD Native card as a digital I/O interface has a latency of 82 samples. - HDX + HD I/O interfaces has a latency of 76 samples before plugins. - third party AAX-DSP plugins add between 30 and 75 samples per instance. - many UAD DSP plugins add 55 samples per instance. There is really nothing more wasteful than talking about latency as something that only exists with sample buffers. This is particularly applicable in an era of DAD/MTRX interfaces which don't adhere to the calculated digilink latency of HD I/O interfaces. Like most things digital, converter latency has improved leaps and bounds compared to the HD I/O latency of 2012 that most digilink interfaces adhere too.

Re: Tracking with Buffersize 32?
Actually we used to get clients in who did complain, back when we got our first ProTools rig (late 90s). Not a huge number, admittedly, but there were definitely some who said it made them uncomfortable. Just my 2p
