hello folks. i want to add 8 seconds of silence to the beginning of several hundreds mp3s. is this possible to do in audacity, or anything else, as someone with no coding knowledge? thanks.
Be aware you will degrade the MP3’s by re-encoding them.
If you still want to do it, you could try “TrimExtend” ( https://forum.audacityteam.org/t/trimtrack-plug-in/14323/7 ).
See here for installing Nyquist plug-ins http://wiki.audacityteam.org/wiki/Download_Nyquist_Plug-ins#install .
Then add TrimExtend to a chain using File > Edit Chains ( http://manual.audacityteam.org/o/man/edit_chains.html ) and File > Apply Chain, choosing “Apply to Files…”.
