I don't think there is such a thing as an MP3 container. MP3 is a codec (technically MPEG-2 Audio Layer 3), not a container format. MPEG-4 AAC audio is conventionally served in an MPEG-4 container. You might be able to put it in an MPEG-2 container instead (to match MP3), but I am not sure that is a sensible or useful configuration.
