Most people are only familiar with it's use at default settings, which would be absolutely destructive to subliminal audio in both ultrasonic and masked formats because the encoding algorithm used at default settings aims to strip out "useless" information; that is, stuff you can't hear consciously. Very faint signal, and very high pitched signal. It is in these very areas that subliminal information is encoded. But if you know how to tune an MP3 encoder properly, you can achieve good compression without removing the subliminal audio. I would estimate that the settings I use only strip out about 5% of the subliminal data, leaving it about 95% intact - which is far and away plenty enough to get great results from. So claims that mp3 encoding will damage subliminals are correct, which is why we say to never re-encode them. But the first encoding, done right, is just fine.
I wonder if you could make subs available in APE or FLAC format? I know they are a lot bigger, but there's a lot of space on modern players. Would it be more important with the new 6G?
