I'm looking for a way to transfer automatically all ID3 tags from one set of mp3 files to another set of mp3 files. I admit I didn't search trough ALL posts and faqs but at first glance this is not straightforward.
The general idea is first to convert hi-bitrate files to lo-bitrate using lame and a one line script for batch sequencing. Could be something like that:
for %x in (xyz*.mp3) lame -h -b128 "%x" "new_%x"
I'm using the fabulous Take Command processor, the syntax should be very similar in a CMD window. Anyway, this is off topic.
Then, as lame doesn't keep the tags , use mp3tag to copy tags from one set to the other.
