Are there any plugins so I can work with MP3 files with Creative WaveStudio?
You can use Creative Audio Pack to encode the files to MP3 format. The reason that this feature was not implemented was related to the price of the encoder application. Creative Audio Pack might not be free, but it will allow you to encode into MP3 format. You can obtain the pack from the official website. It will cost you 9.99$.
No longer available. Any other answer or do we wave the white flag on this sofeware now?
