I have some mp3 on various dir.
I did

find $HOME -name *.mp3|pax -wf arch.tar

The command works fine,but when extract, it recreate the full dirs
for example

tar -tvf arch.tar

Return

dir1/dir2/sound.mp3
dir3/music.mp3
dir4/dir5/anotherdir/anothermusic.mp3

When extract of course will create a lot of dirs.
My desire is a thing like this

find $HOME -name *.mp3|pax -w"possibleoption" -f arch.tar

To obtain an archive like this

/sound.mp3
/music.mp3
/anothermusic.mp3

I know is not safe,but is possible to strip dir path on fly?

p.s= I used pax command for example, but the classical tar is also good

These variations all assume that you've created an archive with the original path stored in the archive itself. They transform the path when listing/extracting the archive.

Using pax with its -s flag:

pax -f archive.tar -s '@.*/@/@' '*.mp3'

Add -r at the start to actually extract the files.

With BSD tar:

tar -tf archive.tar -s '@.*/@/@' '*.mp3'

Change -t to -x to actually extract the files.

With GNU tar:

tar -tPf archive.tar --transform 's@.*/@/@' --show-transformed-names --wildcards '*.mp3'

Change -t to -x to actually extract the files.

The string replacement will remove the path stored in the archive and replace it with a single /.

The equivalent operation for creating an archive with files whose pathnames are read from standard input (transforming the names by replacing the path with /):

pax:

pax -w -f archive.tar -s '@.*/@/@'

BSD tar:

tar -c -f archive.tar -s '@.*/@/@'

GNU tar:

tar -c -f archive.tar --transform='s@.*/@/@' --files-from=-
