Independent data = someone not connected with the patent or software performing measurable tests to prove whether or not this processing accurately "recreate" tones which had been removed by encoding process.
The notion is, on its surface, ridiculous. Either information is lost or it isn't. Trammel may have software which can create new tones which may or may not match the ones which were discarded during encoding, but without independent testing it's impossible to know how accurate they are.
More importantly: the premise of MP3s is that they remove tones which humans cannot hear anyways. The value in "recreating" inaudible sounds is marginal at most.
Your comment about "lots of buttons & sliders" implies you're not a sound engineer and thus wouldn't be able to confirm anything technical about what trammel was showing you.
Even if you were qualified to judge the demonstration he gave you, he easily could have cherry-picked sound samples that happen to work for his technique, and we'd still not know if it works on real-world music.
I have read the website and found *NO* evidence that what's being claimed is actually happening.
I have read the google reviews for the apps, and for the most part they describe its merits as a music playing software, (a purpose which it faces dozens of competitors). Again, none of the reviewers confirms the technical claims put forward by the Trammel patent.
It's very easy to make music "sound better" (a completely subjective standard) simply by distorting the sound via band equalization, which consumers have been doing for decades. the MAXD app has an equalizer, and people who are judging the sound quality are probably responding positively to the placebo effect of differently equalized music sounding "better". and NOT responding to these supposed "recreated tones".
