I was very pleasantly surprised by the great results using the included mic and the phone app....Absolutely. Umik-1 arrives tomorrow (well, today, I'm in ET) and this is when I want to use Dirac on my laptop. The reason I've used basic mic and the phone app the entire time is that honestly I'm quite happy with the results. There were times where I found myself spending hours, days even, building and then tuning something, configuring, reconfiguring, etc... instead of actually listening to the music and watching movies. I'd like to change that, and I've made some progress.
To tell the truth, although I adjusted the target curves "to taste" - objectively speaking, I am not convinced the results are any better than what I achieved in the first 15min using the simplest method !!
I subsequently used the included mic and the PC app, then a UMIK1 and the PC app - more control yes, more quality no.
