Is main_file the "specific file" whose lenght you want to use to shorted "the longest"? > But you seasoned sox experts already know this means > log_track.wav isn't used at all. Of course: out.wav gets trimmed before the input even gets to it, being that main_file itself is one of the inputs. > This also cuts off about the last 1.5 seconds of the out.wav > file as well. It trims out.wav to the length of main_file. > So is it possible to combine these files and trim to the main file? Trim _what_ to to length of the main file? In short, you mail is a mess. Tell us what you you need to do _and_why_. Be as specific as possible. Don't talk about "the longest file" without showing the lengths, or "a specific file" without naming it, etc. Trimming a file to another file's length is easy: sox third.wav trimmed.wav trim 0 `soxi -D prototype.wav` soxi -D prototype.wav third.wav trimmed.wav To concatenating three files, with silence between (say) first and second, just pad the first with silence first: sox first.wav padded.wav pad 0 1.5 soxi -D first.wav padded.wav Then just contatenate them: sox padded.wav second.wav trimmed.wav out.wav soxi -D padded.wav second.wav trimmed.wav out.wav rm -rf padded.wav trimmed.wav _______________________________________________ Sox-users mailing list Sox-users@xxxxxxxxxxxxxxxxxxxxx https://lists.sourceforge.net/lists/listinfo/sox-users
