Hi again,
This is the last question about PiPedal, but i need to ask because I have some doubts.
In the notes, the OP of PiPedal says:
The quality of the audio adapter you use dramatically affects the quality of the guitar effects. Amp models are particularly sensitive to poor signal-to-noise ratios, because overdrive effects boost the level of noise more than the level of the actual signal. For best results, you should choose a 24-bit audio adapter that provides at least 105db (A-weighted) signal-to-noise ratio.
Cheap USB audio adapters, claim to to support 24-bit audio, and happily provide 24 bits of data. The problem is that they are usually providing less than 16-bits of signal (the remaining bits being pure noise).
You will get good results; but not astounding results. Stepping up to a more expensive USB adapter dramatically improves the quality of signal you’re going to get. With a decent USB audio adapters, NAM A2 amp emulations are significantly better than Helix or Kemperer amp emulations.
I personally use and recommend the both the MOTU M2, and Focusrite Scarlett 2i2 4th gen (not the Solo, or 3rd gen models which have significantly less dynamic range). There are plenty of other pro-quality audio adapters that will probably work as well. Check the specs carefully, signal-to-noise-ratio is what matters, not bits of data. (This may show up on a datasheet as Dynamic Range, as well). Cheaper USB audio adapters that sell for less than US$70 will almost certainly not provide adequate signal-to-noise ratio for best results, and invariably won’t provide S/N ratio specs for very very good reasons.
But, the Scarlett solo 4th Gen and the 212 4th use the same converters and the same dynamic range. So, this inacuracy, made me start thinking about the performance of PiSound in this specific scenario.
I have made some tests, and i can say the sound with PiSound is really amazing and i have not heard more noise than usual (with an Scarlett Solo, an Audient iD4 MKII or an Axe I/O One) but i might be using some interfaces that are under the specs. i don’t think so, because all of them are above the 105db floor, but i’m not sure.
So analyzing the datasheet, PiSound claims 110 db, so It may stay barely around the 105db (this is a supposition based of a real use in a real scenario)
My question is if the PiSound, with what the OP is saying, meet the minimum specs and can be use for this particular case. What do you think?
I will say yes, but i prefer to ask to pros.
Thanks for all the support and the welcome.
Eduardo.
