Follow-up Comment #26, bug #45722 (project gnash): Note (for the record): embeded 8-bit PCM `UNCOMPRESSED` and `RAW` event sound is encoded in an _unsigned_ 8-bit PCM format. If you run following commands with `pcmplay-8bit.swf` and `rawpcmplay-8bit.swf` you will hear the correct siren sound: swfmill swf2xml pcmplay-8bit.swf | sed -n 's/.*<data>([^<]*)</data>/1/p' | base64 -d | aplay -t raw -f U8 -r 44100 swfmill swf2xml rawpcmplay-8bit.swf | sed -n 's/.*<data>([^<]*)</data>/1/p' | base64 -d | aplay -t raw -f U8 -r 44100 But if you changed the `-f U8` part to `-f S8` (signed PCM), you'd hear a hoarse wailing instead. _______________________________________________________ Reply to this item at: <http://savannah.gnu.org/bugs/?45722> _______________________________________________ Message sent via/by Savannah http://savannah.gnu.org/
