Correct.

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.
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 ^).

If any .flac is found at the end of a line do the following. Or .FLAC, .fLaC. Any combination of upper and lower case.
Correct.

What is fn?
The previously saved filename.
Quote:
Test all tags and remember the illegal ones.
Yes.
Quote:
Is 'f || f++' just a complex way to say 'f=1'?
No, it's a simple way to say f++ if f = 0 or unset
Quote:
If found illegal tags, then sent them to the output stream. Why use print one tim and the other time prinf?
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.

I don't understand. I thought we were done for flac.
This lines resets temporary variables and empties temporary arrays.
Quote:
Same but for mp3. I guess next step is to combine this two pieces of code to one.
Yes,
see the last version.
Quote:
What does this mean?
The main code
These lines populates the tags array.
Quote:
Aha.. we are finished.
Yep, almost
Quote:
We checked, we sent everything to the output, so what is the need for almost the same code again?
Because every time we're working on the previously saved data,
therefore the last one should be processed after the entire input is read.
