I am new user for Audacity. I have a music file in mp3 format which is of long length. I need to cut it short to create jingle for playing them in background of a standup comedy show. When I cut the big file in small parts, the audio comes in mono format. I want the output to be in stereo mode. Can anyone tell me how to get mp3 format in stereo mode using Audacity when I don’t have its original uncompressed format with me?
