tiny audio interfaces
Anyone remember this little guy? http://www.sonomawireworks.com/guitarjack/
It has me thinking about how great it would be to have a small audio interface, with a 1/4" in and a 1/4" stereo out, thats it. Something tiny like the guitarjack, but with MFi lightning cable instead of the dongle form factor.
Does something like this already exist? I think the SonicPort might be the closest currently. but I'd love something even smaller! small enough to clip onto a guitar strap

smallest i saw is: Alesis Core 1
I don't think the Alesis Core1 has a lightning cable (could be wrong). I think it's just a USB audio interface.
The smallest is the Ik multimedia iRig HD, but you need to use the headphone jack. Many people are adverse to this, but Apple audio is pretty good this way. Just use the headphone jack.
Then there's the Sonicport, which is very good also and has the headphone and line out jack on it.
I'd be curious as to the differences between using the headphone jack vs usb down stream jack. I'm thinking there should be little difference, and it's conceivable that the headphone jack could sound much better and have lower latency. The only way that the USB downstream would be essential, would be for hardware monitoring (dry signal).
I'm just rambling really, as I was thinking about this today actually. Like many of you, i'm constantly fiddling with this crap
iRig HD uses lightning or 30pin.
apogee jam 96k is what i use. lightening and 30pin included and USB also.
I use the guitar jack v1 with the Lightning to 30 pin cable. Works great for my purposes. The usb version 2 - you may can use your lighting to USB cable. May want to ask their tech support to be sure if interested...
So it looks like the only option for 1/4" input + 1/4" output is the SonicPort? Wow, I would think there is a market for more devices like this, where all you would need is a guitar amp and normal 1/4" guitar cables.
1/4" stereo out isn't too useful for plugging into PA's, or amps, or stereos, two separate 1/4" outputs (left and right channels) are more useful in the pro audio world. That way you don't need to carry precious, unusual adapter cables always.
The 1/4" stereo is only good for big headphones, but most of them now are 1/8" anyway, with a 1/4" adapter stuck on the end.
The bit of recording I've done plugging the iPad into a computer DAW has shown the iPad's headphone out is noticeably noisy. It's a consumer device, so it's worthwhile to have an audio interface for the pad, if noise and audio quality is an issue.
True^ the ideal device would need both Mono 1/4" plus 1/8" stereo.
SonicPort got it right, I just want smaller
Is there a reason 1/4" ins are always mono?
