TK, for me, 320kbps is hi-resolution audio and you can not make any distinguished difference compared to FLAC. Enjoy the giveaway, it is a good software.

"MP3 is barely Hi-Fi let alone Hi-Res! MP3 is lossy in ALL it's forms and always below CD-Audio quality..."

"for me, 320kbps is hi-resolution audio and you can not make any distinguished difference compared to FLAC."

Rather than take my word for it, here are a couple results from a quick Google. TK's correct. Lossless always beats lossy. That said, judging audio quality is subjective, and Very dependent on the hardware used. There's a big difference between *studio reference* headphones & speakers compared to popular alternatives such as Beats, or lower cost / fidelity alternatives. The acoustic characteristics of the room when listening to speakers Matters. And so does a person's hearing. Long story short, if you're happy with whatever audio quality you listen to, Great! But try not to assume someone else would be equally happy.

mike, for me I If I were self opinionated and wanted to make up stuff... I because I have lost hearing in one ear and have age related hearing loss in the other ear and have consumer grade built in sound chips in my computers and TV's I could pretend because I cannot, unaided, distinguish between mono and stereo (I miss that) and have significant loss of high frequencies that 16ksps at 64kbps mono is just as good as 24bit 192ksps FLAC so therefore both are hi-res audio... but really we should move beyond our very limited range of personal experience. Firstly you will have to BUY a high quality Digital to Analog converter box with significantly more than the signal to noise/dynamic range of less than CD quality (the DAC shipped in PC's is almost always less than CD quality that's why YOU think 320kbps sounds as good as a CD or FLAC) The sound source and digital processing and mastering of the FLAC needs to be consistently Hi-Res all the way through to get Hi-Res in the FLAC data, you can't take cheap and nasty Apple music or Spotify download and convert it to FLAC and have BETTER quality than you started with... As with computers Garbage in Garbage out. You will also need decent specialised audio amplifier with considerably more signal to noise ratio/dynamic range, low intermodulation distortion, low harmonic distortion compare to consumer grade made to a price point cheap single chip Class D amplifiers in every laptop and desktops sound system before we even come to the room, loudspeaker type and positioning and so on and young AND discerning ears... After all that you may not have the hearing ability to perceive the differences (plural) between 320Kbps and normal CD-Audio let alone between 320Kbps MP3 encoding and 24bit 44.1Ksps FLAC let alone 192Ksps FLAC. just some of the differences an almost silent background no discernable hiss even at damaging listening levels, Phase accurate audio so it is possible to place an instrument in an orchestra sound stage in both depth and left and right position consistently... record the ambience of the room(s) the piece was recorded in and have that reproduced at the listeners ears... CD-Audio can do some of that but it lacks dynamic range, resolution at upper-mid to high frequencies that young ears have the possibility of hearing. MP3 is barely Hi-Fi even at 320Kbps your laptop and computer speakers certainly are not even mid-Fi if there were such a codified definition but they certainly are not Hi-Fi! How can I know this... simple really assuming you were not just trolling and tell your subjective personal truth... from what you typed.
Happy new year.
