Quick question bout pmp_usb vs ml_transcode

[robdog2004]

to simply answer you question
yes pmp_usb uses ml_transcode when it finds a incompatible track
for your file it must have been a low grade mp3 file to begin with
there are 2 grades of mp3 (that i know of)
the first is mpeg 1 layer 3, this is the highest grade and give the best sound (normally a original recording from a cd or etc)
the second is mpeg 2 layer 3, this is a subgrade file and sometimes has sound distortions (usually when reencoding a 64bit file to 128bit or when changing formats (for example aac to mp3))
other than this i can only recommend redownloading or reencode the file from its original source (if available)

Hi Rob,

Thanks for the quick explanation of the 2 mp3 grades. I'm familiar with mpeg 1 layer 3 being the standard that's been in use for many years. Anything written about MP3 from before layer 3 is usually quite verbose and excessively detailed, so I really appreciate that.

However, I think you misunderstood me. The resulting AAC file was created from a FLAC file. So, quality and format shouldn't be a problem. FLAC is lossless.
