High Bitrate ~320kbps MP3 vs. Lossless audio, Spoiler: mp3s were TRANSCODED from Lame free-format.

Happy New Year and greetings everyone! I know the folks here at Hydrogen audio have been around and back with regards to these tests... Nonetheless, I've been collecting data from around the audio forums since early Dec 2012.

Since early December 2012, I've opened up a survey to see if music lovers & "audiophiles" around the world can tell the difference between high bitrate ~320kbps MP3 against the original un-lossy-compressed CD audio. I'm only planning to collect data until the end of January 2013.

So far, I have >70 responses from around the world with 5 continents represented. Folks have been using everything from inexpensive (but good) headphones to megabuck separates >$50K for this. There's 2 weeks left so if you've ever been curious about participating in a blind test or just want to add to the dataset, here's your chance :-).

The "test" is relatively simple and consists of 3 musical passages encoded as "Set A" vs. the same songs "Set B"; one of which was MP3 encoded.

Come to my blog to download the music and fill out the survey:

Thanks and have a wonderful 2013!

OOps - the title should have read 'ends Jan 31'... [fixed]

Meaning no disrespect, but comparing those options are not indicative of a solution. I wonder what is the objective. To clarify:

1. To use such high bit-rates is to achieve transparency/archival.

2. Any user using either of those options is likely dealing with higher space confines.

Putting all cards on the table, I would not entrust to archive with 320kpbs MP3, nor I would put those massive MP3's on my player (i.e. LAME -V3 thru -V5 is "good enough" on my portable). Currently, I am content with AAC ~125kbps without any qualms. smile.gif

If I misunderstood that this was a listening challenge, then I apologize for my interruption. I probably could not ABX MP3 320kpbs and lossless.

I hope Mooreís Law has taken us past the point where people feel a need to connect any lossy configuration to archival. IMO, the middle ground makes no sense: either choose a bitrate that (aside from in possible highly rare cases) is transparent, or use lossless. Space confines, obviously possible, but then donít waste space on 320 kbps for listening! If someone lacks the space to archive, then thatís a bit of a shame, but thereís no point in settling for anything other than lossless if one wants music in a reliable and future-proof form.
