Hi, maybe I can give you a new view on your problem: If I understand you right, you want to extract parts of audio files and merge them into a new file? Apart from the obvious answer "That is what a DAW does!" [1], maybe instead of "play parts of files into another file" you can search the available commands for "extract", "split", "merge" and "append"? Throw "convert" into the mix… [1]: Ardour, audacity and others are gui-tools fulfilling this. I also remember ecasound and nama (https://freeshell.de/~bolangi/cgi1/nama.cgi/00home.html) to be command line DAWs. Maybe that helps? - Arnold Am 18.04.20 um 10:50 schrieb John Murphy: > I use a program which plays regions of various .wav files.
