What latency times can be achieved with an AXE I/O today in

[dimugi]

To all those who use the AXE I/O!

Can you tell me what latency times you usually achieve?

I'm mainly interested in latency times with a buffer size of 128 milliseconds and less.

I'm about to make a purchase decision and can't find anything about it.

Have you ever modeled your amp with the device?

According to IKM, it should work.

I'd be interested to know if it actually works.

Your experiences would help me a lot.

Many thanks and best musical regards!

I'm asking because there are video posts on the internet where people talk about the AXE I/O, basically praising the device, but criticizing the latency times at the time.

In 2019 - 2022, the total latency was probably over 8 milliseconds with a buffer size of 32 samples, and many devices today can already manage that with 128 samples.

IKM support wrote to me today that the round trip time with a sample rate of 32 would be around 4 - 5 milliseconds, which isn't the best times, but significantly better than in 2019.

Has no one checked this in their DAW yet?

Delamar measured the interface as follows and that's why I've now ordered the interface:

With a buffer setting of 64 samples and a sample rate of 44.1 kHz at 24 bit, the resulting latency in Logic Pro X was 3.5ms output delay. This is well below the critical limit of 10ms.

When I'm using it, I'll post the values ​​I determined here.

Running Live on a Windows machine with i9 12900, 128 GB memory, I measured a total latency of 4.72 ms with a buffer size of 32 samples.

Running on an M1 Pro mac laptop with Reaper
44.1 KHz sampling rate in AXE I/O
In Reaper used block sizes of 16-128 and it was very consistent to take the measured latency in samples and subtract 2X the block size to normalize the values.

Measuring per loopback test as demonstrated by Kenny Gioia here: https://www.youtube.com/watch?v=HZcXZ9kEJbY

The AXE I/O self reports a latency of 6.4 ms
Adding an offset of 91 samples (2.1 ms) aligned the loopback recording.
This is a total latency of 8.5 ms.

Final test was to enable the "Use audio driver reported latency" and add 91 samples to the input manual offset and all block sizes from 16→128 stayed aligned.
