[linux-audio-dev] programming time signature and tempo

Hello everyone, I've recently started updating wav composer not toilet (wcnt.sourceforge.net) the humourously named, rarely used, not-real-time audio sequencing, sampling, synthesis wav file generator. can anyone point me to some information about time signatures and tempo which would be useful from a programmers perspective. I've looked on the internet and what I found either told me nothing I did not know or just said that time signature was irrelevant (ie for notation only) and it was down to the performers to decide. so far my code is based on 4/4 (4 'beats' of quarter notes per bar/measure). a single bar has a value of 256, with halfnote 128, etc. What I need to work out is how a different time signature will effect this, would I need to change the value of a bar etc? I tried some experiments in cubase (i've not got any realtime sequencers working in linux yet) with audio blocks snapped to every half bar. What confused me completely was when I changed the time signature to 5/8. the snaps to half bars stayed in the same place, but the snaps to bars changed, ending with every 5th block snapped to a half note actually landing on a bar. Uh? can any one shed any light ? thanks in advance, James Morris. ~(sirromseventyfive)~ _________________________________________________________________ Find a cheaper internet access deal - choose one to suit you. http://www.msn.co.uk/internetaccess
