Add silence to mulitple audio files all at once.

I have a bunch of audio files (about 100 MP3s), and I would like to add an automatic 1.0s of silence to the end of each one. How would I go about doing this? Do I need to use the “batch”? Is there a way to do this without “the batch”?

Use the Trim / Extend Nyquist plugin in a Chain. See http://wiki.audacityteam.org/wiki/Download_Nyquist_Plug-ins#Installing_plug-ins for how to install a Nyquist plugin.

Note that you will degrade the quality of all the MP3s by re-encoding them.

There is a “direct” MP3 editor called mp3DirectCut that does not re-encode and so does not lose quality. I don’t think it can insert silence unless you create a one second silent MP3 and join the files. I also don’t know if joining the same file to other files can be done as a batch.
