How to identify the bitrate of audio streaming to HomePod

On a HomePod (2nd generation) I often stream (a) radio stations such as KNKX FM , and (b) music services such as SomaFM . Is there way to inspect the bit-rate and compression method (such as AAC ) of the stream? And for sources that offer a choice of bit-rate and compression methods, is there any way to choose between them on a HomePod?
