I want to compress a audio from bluray and i don't know the quality setting for 7.1 channels. what bitrate is the most used for this type of audio?
Try StreamFab Downloader and download from Netflix, Amazon, Youtube! Or Try DVDFab and copy Blu-rays!

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.Avisynth functions Resize8 Mod - Audio Speed/Meter/Wave - FixBlend.zip - Position.zip
Avisynth/VapourSynth functions CropResize - FrostyBorders - CPreview (Cropping Preview)
