Interesting... On the playback side CODECs sometimes don't care that much, they clock data in and if it stops early they just go on to the next sample with the width being used to configure filters or something. The signedness is a bit more surprising I have to say :/ --/7+LvQqw8N5lf/3J Content-Type: application/pgp-signature; name="signature.asc" -----BEGIN PGP SIGNATURE----- iQEzBAABCgAdFiEEreZoqmdXGLWf4p/qJNaLcl1Uh9AFAl4d1PgACgkQJNaLcl1U h9D7qgf+KdBUSPJ38rdTjpyt2K7lYvMyXL5+ZUVws3WSh8Mf6NKFkc2TRAtLJLMm cqQxLWHy6m4R7X+tZtn2iwoi5f+RDi8uYHOcvSfU9qoI5KQeCgHQjXwaU6tnx7fx UeeJ0kwtqgsO3xcGpn6DUjoujSvxI9dyr83h0MS3EhX216xvzEDBgF/ujsbnYfCj ukYd9ZB/jD9aFtelkTHgJh6zeKPkcLTLhBB+/i3AalSM+yBR2eLgXkVUGBB7pPMD k4LL/2R2f91ziU7J/6NgZuO+X6RzXAmYNDs2nH28v9sQotj1KTXXFl3/t5L42zm7 3XPg4S+5Q5SefOGfY4kvylDWjank2A== =ff88 -----END PGP SIGNATURE----- --/7+LvQqw8N5lf/3J--
