So in addition I use a Windows only app on an aging laptop called Lossless Audio Checker.
Actually, there's also a Mac (and Linux) version of this software but it's command line only and I'm far to be a "Power User", lol.
I would like to have a tool like that to help me with the ambiguous situations, although in reality I would like to be able to distinguish every single case on my own without doubts.
Btw, is that software trustworthy?
Despite having been a computer programmer at one point in my career I really can't be bothered with CLI only apps nowadays. Call me lazy but if it's not GUI then I'm not interested.
As for being trustworthy I was impressed with the fact that Lossless Audio Checker (
https://losslessaudiochecker.com) appears to be written by a couple of people who produced study papers for their respective universities in Toulon and Marseille, France which are available on the webpage. Whilst much of the science went over my head the bits I did understand suggested that the algorithms they use are well thought-out and accurate. As I say I use LAC if Spek doesn't provide an adequate visual result. So effectively as a back-up.
Oh, and thanks, Greta for the FLAC share of AMPS 119.
