How to download 96kbps HE-AAC radio 3 stream?

[ChenZhe]

Hi Everyone,

I am out of UK, so normally I could only download in 'hlsaaclow' and 'flashaaclow' mode which are of 48kbps HE-AAC quality @ 48kHz.

However, the aac stream embedded in flash player is of better quality which is  96kbps HE-AAC @ 44kHz. An example link is:

What is the correspondent mode to download the 44kHz 96kbps stream ?

Best,
Zhe
