how can i, using function, library, whatever have to, concatenate 2 .wav files? input should absolute paths, , output audio file created , placed (not played) somewhere, doesn't matter where. i writing mac command line application in xcode 6. the .wav file format simple format, consisting of fixed header defines audio file's properties; namely endian-ness, number of channels, , sampling rate. documentation defined on intertubes. off top of head don't recall if common library offers convenient way (it's worth looking through libsndfile's api documentation , fit bill). in case, shouldn't tough read headers of both wav files, check format, , create output file. if both wav files have same endian-ness, number of channels, , sampling rate, procedure trivial, otherwise have resample/remix @ least 1 of files.

this question has answer here: short description of scoping rules? 7 answers is safe read loop variable after loop (using python 2)? purpose check how many iterations in loop done. here code show idea: a=[1,2,3,4,5] in range(len(a)): if a[i] == 2: break print # output 1, safe read here? yes, fine read there. because when create for loop, internally, has mechanism create indexer (in case being i ) , increases 1 one assigning new value every time. thus, can use i after for loop. after: a=[1,2,3,4,5] in range(len(a)): if a[i] == 2: break i isn't dropped. drop i , can use del keyword: a=[1,2,3,4,5] in range(len(a)): if a[i] == 2: break del #deleted here print # give error! while replace is, need redefine it: a=[1,2,3,4,5] in range(len(a)): if a[i] == 2: break = [] #now l...
