Yes ,this works. Thanks. Let's see if I understand what's happening. (Hmm.. there still is a little hickup. See the bottom for that.)
find all mp3 and flac files, get the info and pipe the stream
Define variables. What does the ^ mean in the pattern? After that it's any amount of spaces followed by unknown or track followed by any amount of spaces and digits. Followed by any amount of spaces till the end of line.
If any .flac is found at the end of a line do the following. Or .FLAC, .fLaC. Any combination of upper and lower case.
What is fn?
Test all tags and remeber the illegal ones.
Is 'f || f++' just a complex way to say 'f=1'?
If found illegal tags, then sent them to the output stream. Why use print one tim and the other time prinf?
I don't understand. I thought we were done for flac.
Same but for mp3. I guess next step is to combine this two pieces of code to one.
What does this mean?
Aha.. we are finshed.
We checked, we sent everything to the output, so what is the need for almost the same code again? But what is FS=:?
Oh.. I noticed something, It's not really perfect yet. It seems to go wrong when switching to antother format:
From Alex Roeka track 08 is correctly filled, but I still get a message that the tracknumber isn't filled, which is a flac tag, not a mp3 tag. See correctly detected track 01. The property is called 'track' not 'tracknumber'
And If I test with all tags filled correctly. This track is still being wrongly accused:
Well actually it is correctly detected that tracknumber is missing, because it isn't there. That is because tracknumber shouldn't be in a mp3. There just should be no check for tracknumber at all. For mp3 then. For flac of course there should be.

Correct.

Followed by any amount of spaces till the end of line.
In regular expressions context ^ is a zero-width match at the beginning of the line.
So the above pattern matches:
0 or more white spaces, followed either by - unknown or track followed by 0 or more
white spaces followed by 1 or more digits - with 0 or more occurrences of the last unit
(described between - and - ), followed by 0 or more white space characters. The $
matches the end of the line (the opposite of ^).

Correct.

The previously saved filename.

Yes.

No, it's a simple way to say f++ if f = 0 or unset

Correct. printf is used to format the output,
you can use print instead, if you find it
clearer:
Yes, may be in this case it's clearer.

This lines resets temporary variables and empties temporary arrays.

Yes,
see the last version.

The main code
These lines populates the tags array.

Aha.. we are finished.
Yep, almost

Because every time we're working on the previously saved data,
therefore the last one should be processed after the entire input is read.
I have a lot number audio files in the MP3 proprietary format, I want to convert them to 'opus' the free and higher quality format, with keep metadata also.
