Make an audio file (really) long-winded
Daily repetitions are an illusion anyway.
— Tristan Bath, Shilla Strelka
This Python script concatenates audio files in a directory. It depends on sox while circumventing one of its shortcomings: the number of arguments in a command such as sox input output.wav is limited to 100. Against this problem, longwind assembles audio files in small batches (default size = 50) recursively until all batches are recombined onto the same file.
Longwind has been used by composer Florian Hecker to produce Syn As Tex [AC], a monumental computer music piece (51 hours). Listen at: https://etat.xyz/release/SynAsTexAC
