Actions that end with ‘…’ and have “Parameters none” listed will pop up a dialog during the script to get the paramters, and are not properly supported by scripting. Use at your own risk.
Do you know of some workaround? I have like 2k small files and want to batch process them using some of the effects (e.g. PaulStretching).
Does the scripting command “Import” (“Import2”) from the “Extra menu > Scriptables II” work for you?
Note that you have to use a fully qualified file name, for example, to import a file “file-name.wav” from the Desktop of a user “user-name”:
#!/usr/bin/env python
# -*- coding: utf-8 -*-

import fnmatch

toname = '/tmp/audacity_script_pipe.to.' + str(os.getuid())
fromname = '/tmp/audacity_script_pipe.from.' + str(os.getuid())
EOL = '\n'
print("Write to \"" + toname + "\"")
if not os.path.exists(toname):
print(" ..does not exist. Ensure Audacity is running with mod-script-pipe.")
sys.exit()
print("Read from \"" + fromname + "\"")

PS.I had some problem with missing ChangeTempo effect, but I decided that I’ll use soundstretch directly, in command line (I assume you still use it, just for some reason it did not get installed).
), I managed to build Audacity 2.3.3 with mod-script-pipe.
