    480kbit for AAC-LC is a good place to start.

    For AAC you can use variable bitrate encoding and select a quality instead, so it works much like selecting a CRF value for x264 rather than a bitrate. What's your desired output format, because obviously the type of encoder used will make a difference. Without knowing that it's a bit like asking what bitrate to use to compress video without knowing the encoder type.

    If you are wanting AAC for the output, you might want to read this

    but the bottom line is for 7.1ch AAC encoding, you probably should use QAAC.
