That's OK, but don't waste effort on compression.
Standards say you use the pax format, or at least
something like tar or cpio.

You can put sample rate info in the header of a *.wav file.
This is really the perfect format for your data.

Use FLAC if you want to get fancy.

Whatever you do, don't spam the journal.

I just finished deleting a huge pile of spam from my journal.
Well, not counting the two things that refused to be deleted.
This was not an enjoyable task. As with an email inbox, I run
a risk of deleting something I want to keep as I wipe things
out. This stupid busy-work chore should never be needed.

A few buttons is nothing. If it gets to be dozens of buttons
or more, then you might add a "save settings" button. Hopefully
you can save this with the activity itself, rather than putting
more junk onto the desktop^H^H^H^H^H^H^Hjournal.
