Need to know ASIO driver buffer size in samples

[whyterabbyt]

Anyone know of a host or tool which determines the actual ASIO buffer size of the current latency setting in samples. Got a problem with a plugin and I need to give the developer the buffer size info, but the millisecond settings from the ASIO control panel are more than likely to be approximations...

if you know the latency in ms do this:
(0.001(Sample Rate))*(time in ms) = samples

[blaster78]

if you know the latency in ms do this:
(0.001(Sample Rate))*(time in ms) = samples

that will only work if you know the exact time in ms, which if rabbyts asio control panel is anything like mine he doesn't.

i have seen something tha does this though, i cannot for the life of me remember where though, i'll have to have a think and come back to you.

cheers,

Maybe the AsioControlPanel can help?!

Since the buffers are likely to be in nice powers of 2, I'd look at the ms at 44.1KHz and convert:

~1.5ms - 64
~3ms - 128
~6ms (mine reports 5.9) - 256
~12 (11.8) - 512
~24 (23.4) - 1024

etc

Exactly.

Thats not how the available latencies go, so no, I dont think the buffer sizes are all powers of two, at all. The available settings are actually 2,3,4,5,6,7,8,9,10,12,14,16,20,50,75, and 100 milliseconds.

Ta, i'll have a look at that.

<EDIT> Yup, thats giving me a result for 'preferred' buffer size, and its associated value in milliseconds, which is what I need I, think.

And no, they're not powers of two, and they're just ever so slightly different from the calculation outsomnia20 posted as well.

Interestingly, though, it also reports values for 'ASIOGetLatencies' for both input and output, and they're somewhat different from the 'preferred latency'. Curious. Anyone know what they refer to?

OK, I've just never seen a card that doesn't go in powers of 2 byte buffer sizes (I've used half a dozen different cards over the years). You learn something new every day...

what audio card are we talking bout here? by the way ableton live reports samples and exact latency

EMU 1820M.

try live 5 demo i am positive it will give you exact samples and MS.

I'll give it a go tomorrow and see if it ties with that ASIOControlPanel thingy. Ta.

Cantabile will show it on the Audio Driver page in Options.
