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 + + + +bash-3.2$ cat test1419968848.wav | xxd | head +0000000: 5249 4646 2870 db01 5741 5645 666d 7420 RIFF(p..WAVEfmt +0000010: 1400 0000 0100 0200 0000 0000 10b1 0200 ............. +0000020: 0400 1000 0000 0000 6461 7461 0070 db01 ........data.p.. +0000030: 0000 0000 0000 0000 0000 0000 0000 0000 .............│·· +0000040: 0000 0000 0000 0000 0000 0000 0000 0000 .............│·· +0000050: 0000 0000 0000 0000 0000 0000 0000 0000 .............│·· +0000060: 0000 0000 0000 0000 0000 0000 0000 0000 .............│·· +0000070: 0000 0000 0000 0000 0000 0000 0000 0000 .............│·· +0000080: 0000 0000 0000 0000 0000 0000 0000 0000 .............│·· +0000090: 0000 0000 0000 0000 0000 0000 0000 0000 .............│·· +bash-3.2$ cat test142*.wav | xxd | head +0000000: 5249 4646 2870 db01 5741 5645 666d 7420 RIFF(p..WAVEfmt +0000010: 1400 0000 0100 0200 44ac 0000 10b1 0200 ........D....... +0000020: 0400 1000 0000 0000 6461 7461 0070 db01 ........data.p.. +0000030: 0000 0000 0000 0000 0000 0000 0000 0000 ................ +0000040: 0000 0000 0000 0000 0000 0000 0000 0000 ................ +0000050: 0000 0000 0000 0000 0000 0000 0000 0000 ................ +0000060: 0000 0000 0000 0000 0000 0000 0000 0000 ................ +0000070: 0000 0000 0000 0000 0000 0000 0000 0000 ................ +0000080: 0000 0000 0000 0000 0000 0000 0000 0000 ................ +0000090: 0000 0000 0000 0000 0000 0000 0000 0000 ................ |
