ok well the last thing that needs to be done with mrswatson, I need some sort of way to pass tempo on the commandline. for some reason, there is
a commandline argument for it, but it doesn't seem to work? we had to hardcode tempo, if you remember
seems like it should be easy to fix yeah just change hardcoded value with value from cli variable it already have let's take a look at it? sure
https://ccrma.stanford.edu/courses/422/projects/WaveFormat/
5249 4646 2470 db01 5741 5645 # riff , size, wav
666d 7420 # fmt
1000 0000 # chunck1 size
0100 0200 # PCM, 2 ch
44ac 0000 # Sample rate. so wee that in original wav it's 00 00 0000. yeah also
it's 1000 0000 vs 1400 0000
4 is tbytes longer htoo, yeah it is...
kww
ok
5249 4646 === "RIFF"
2870 db01 === size of whole file
but in the second one
2470 db01 is the size of the whole file...is that an error do you think? could be but it's looks like 4 bytes short only well
docs say:
This is the size of the
entire file in bytes minus 8 bytes for the
two fields not included in this count:
ChunkID and ChunkSize.
almost like he forgot to subtract one of them? y or subtracted too many...not sureep, can fiix that too. ok
should it all be in this function in the code we were looking at? yep. ok I'll try to fix it I guess hoping I'm not going
to get confused about subtracting binary or something, are the lengths we're dealing with here all integers/decimals? yes
so it should be easy? yep
yeah thanks, slow connection can't find anything
