I wanted to find out if there is a way to create 30 second clips (with a start time in seconds) of .wav or .mp3 files in C# (or using a C# library). Most of the code or libraries I've seen seem related to recording and playback, but what if you just want to do processing of an action like this?
Google: c# create mp3 clips
Hit #1 is your question
Hit #2 is: Audio Libraries for MP3 editing asking specifically "to be able to dynamically create 30 seconds clip of MP3 files"
