Pocket-Size Audio Interfaces: Driver Latency Bro-Down 2020

Pocket-Size Audio Interfaces: Driver Latency Bro-Down 2020

Hello y'all,

If RME Babyface Pro is the undisputed King of low-latency & rock hard stability, then:
Who's the Queen of pocket-size Audio Interfaces?

I've recently carried a quick comparison, and ended up with 2 contenders for the throne:
1. Rode AI-1
2. Apogee One

I wish I could also compare the following (perfectly qualified) pocket-size contestants:
• Premium:
- UA Apollo Arrow
- Focusrite Scarlet Solo
- NI Komplete Audio 1
- Audient iD14
- Motu Track 16

• Mid-Market:
- M-Audio M-Track 2x2m
- Roland Rubix 2x2
- Tascam MiniStudio US-32
- IK iRig Pro Duo

But, I either didn't get any reply from their parent companies, or didn't have time to shoot them an email.
So, if you have the Latency Specs of any of them (even in the same family), please feel free to share them, in the same fashion as the specs listed below.
» See "Template E-Mail" to send manufacturers at the end of this post.

So, which one has the best Latency / most robust Drivers?
The answer depends on how popular this thread gets.

Note that we're mainly interested in Latency + Driver Stability here, but of course, feedback on their "Class-A" amps, Headroom, Output Gain, and more would be great.

After harassing Rode & Apogee, here's what I've been officially told:

Setup: Cockos Reaper on Windows 10
44.1 kHz
- 64 Samples = ~1.4ms
- 128 Samples = ~2.9ms
- 256 Samples = ~5.8ms
- 512 Samples = ~11ms
48 kHz
- 64 Samples = ~1.3ms
- 128 Samples = ~2.6ms
- 256 Samples = ~5.3ms
- 512 Samples = ~10ms
96 kHz
- 64 Samples = ~0.6ms
- 128 Samples = ~1.3ms
- 256 Samples = ~2.6ms
- 512 Samples = ~5.3ms

Setup: Logic Pro on Mac OSX

32 buffer in Logic
44.1k:* * 5.5ms
48k: * * 5.2ms
88.2k:* * 4.5ms
96k: * * 4.4ms

64 buffer in Logic
44.1k:* * 7.0ms
48k: * * 6.6ms
88.2k:* * 5.3ms
96k: * * 5.1ms

128 buffer in Logic
44.1k:* * 9.9ms
48k: * * 9.2ms
88.2k:* * 6.7ms
96k: * * 6.4ms

Template e-Mail to send to the Manufacturers:

Subject: Pre-sale Question about the *****


I'm looking forward to buy the *****, as it's both compact and has a great value & design.
Yet, my main concern when buying an Audio Interface is its proprietary ASIO Driver's LATENCY.

So my question is, for the following common Specs:
- OS: Win10 or OSX (x64)
- Specs: Core i7 / 16Gb of Ram / 512Gb SSD
- DAW: Cubase, Live, or Studio One, Logic (etc.)
- DAW's Bit Depth: At least 32 Bit Floating Point

What's its Latency in Milliseconds (ms) for the following Buffer Block Size?
- 32 Samples in 44.1k / 48k / 96k
- 64 Samples in 44.1k / 48k / 96k
- 128 Samples in 44.1k / 48k / 96k
- 256 Samples in 44.1k / 48k / 96k
- 512 Samples in 44.1k / 48k / 96k

Thanks in advance for all these details, and for your precious time!

I had the feeling this won't get much attention, but woof...
Wasn't prepared to being completely ignored.

Maybe should I post it in another more appropriate sub-forum?

I bought the Ai-1 based on your numbers here. Very nice for tracking guitar/bass and amp sims the Di sounds very good, haven't really tried the preamp on a mic yet. Thanks for the tip! Not as stable as my rme raydat when mixing but switching between them is easy. I've tried to find info about how to read the latency numbers up to the right in reaper, there are one ms number to the right and one ms number to the left, do you know the difference between them and how to read them?
