Hello Zimran Rafique: People from the community please correct me if I’m wrong here, but it doesn’t matter what kind of file you’re trying to transmit (it doesn’t matter what kind of file you’re opening with the File Source block). It’s just bits. You don’t need to convert MP3 to PCM. As long as you can open the MP3 file and read the bits, then you should be able to transmit them. Can you be more specific as to how the File Source block failed? What error(s) do you see?
