I spent an hour reading this board before deciding to registering an account and posting this question. I am undergrad computer science student working on a project that will convert a MP3 to the OGG format using CUDA C. CUDA C is one of the languages that allows one to run programs on the NVidia GPU.

The project that was assigned to me was given a MP3 file, convert it to the OGG format. I never had to write an audio program before but my understanding since both the MP3 and OGG formats are lossy that it is not recommended to convert directly from MP3 to OGG. Anyways, the question I have is how should I start doing this assignment? I spent sometime looking online for algorithms to rewrite to run on the GPU but I couldn't come across any - I just found existing DLL files to use.

Thanks for any input given.

Just to clarify, since this comes up a lot, there’s no such thing as a “direct” conversion between two different formats. The user may not always be made aware of the process, but the conversion always involves, as Ouroboros said, decoding the source file to uncompressed audio (PCM or a containerised variant thereof such as WAV or AIFF) and sending this to the destination encoder.
