Last month I wrote an article on CodeProject explaining how you can use NAudio to encode or decode audio in any format for which you have a codec. I’m linking to it here, as it’s one of the topics I get asked about regularly. If you want to know how to decode or encode MP3, WMA, AAC, GSM, a-law or any other formats, then head over there. The article includes a lot of background information that will help you understand why some conversions can’t be done in a single step. I wrote it to give me something to point people to when they have questions about various encoding or decoding tasks with NAudio.
