This (the original problem) has been fixed in SoX 14.2.0. There is no internal limit on the number of files anymore.
There are still limits from the OS/shell: 1. The length of the command line is limited, a longer line may be silently trimmed. To work around this, use a playlist file (.m3u) instead of listing the input files on the command line. 2. SoX opens all of its input files before processing, so the OS has to support that many open files. I suspect Mark (comment #1) hit the first problem. ** Changed in: sox (Ubuntu) Status: New => Fix Released -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/252093 Title: sox does not handle more than 32 files To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/sox/+bug/252093/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
