The advantage of profiling an amp is that you've got access to an unlimited test set so in that sense it's not a problem.
I could see it potentially needing a bit of grunt to train, but it depends how complex the network is and it might not be all that fancy.
And yeah...it's reasonably likely that this isn't the most complex of neural networks, and it comes pre-trained to do one job. Not only that, but it doesn't have to do anything in realtime in terms of the profiling. I doubt performance is going to be a problem there.
There's one feature which nobody seems to have tagged as important - this thing uses wifi to connect to other devices, not Bluetooth. I can't put my finger on exactly why, but this pleases me no end.
I’d be happy to be proven wrong if someone has a paper or similar that shows a performant implementation.
Anyway there clearly is a technical
issue of some sort if they’re not
offering this to users given that it’s a big disadvantage over their competition. I’d be interested to hear more on this from them.
And, as pointed out by Drew, we're talking about a trained model here. It'd be absolute lunacy to release a product like this with an untrained model, because it'd likely make the product behaviour relatively unpredictable over time (given that the manufacturer no longer has control over the input datasets).
Much more likely is that each amp model is a separate trained network, and a new amp means a new training.
And no, the SHARC application domain is completely different from a GPU.
DSP processors are primarily designed for low latency flow processing with little no parallelism and where the primary design constraint is real time operation.
GPUs are designed for extremely high parallelism of fairly primitive computation units, with very little consideration for latency.
The application domain is at the opposite end of the spectrum, there’s a reason no one does real time audio on GPU and people don’t use DSP chips for machine learning.
I’m so bored I might as well be listening to Pink Floyd
