WAV is a pretty simple container format. The length is written in a very expected place in the header: http://en.wikipedia.org/wiki/.wav http://ccrma.stanford.edu/courses/422/projects/WaveFormat/ E.g. the following: wav_size() { LANG=C cut -b 41-44 "$1" | head -n 1 | hexdump -e "\"$1:"'$1: %u\n"' | head -n 1 } -- Tzafrir Cohen icq#16849755 jabber:[email protected] +972-50-7952406 mailto:[email protected] http://www.xorcom.com iax:[email protected]/tzafrir _______________________________________________ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- asterisk-users mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
