If I simply '>' the input, which was going to aplay, to a file, it's done in a flash. Unplayable, but the file contains data. Could I write a header first somehow? Or a container format would be OK.
there are for sure "correct" ways to do it. If you want to use pure bash magic here you are: Header of a wave file contains 44 byte. To extract it to a file use: head -c 44 original.wav > header.bin Now you can use your file from above (let's call it part.raw) and use: cat header.bin part.raw > newname.wav You should be able to play the new file. Be aware that the header is correct except for the length information. You might fix this with wavfix (https://github.com/agfline/wavfix). Furthermore if your parts are not cut at a sample boundary (e.g. a normal wav file is stereo 16 bit per channel thus 4 byte per sample) you will get noise.
