Yes it is.
It is still developed and you are able to do so much more, besides stream transcoding.

Unfortunately, Dennis, my source stream is 128kbps and will never go
higher. Is Liquidsoap still a good idea?

You can avoid this by feeding liquidsoap or stream transcoder with a highquality or even transparant stream and trancode this to the different streaming formats you like. I used to do this by feeding a flac stream to liquidsoap and transcode this to 5 different stream formats i needed. But you might be fine if you feed your transcoder with 320 kbps AAC and transcoder this to lower formats. Maybe experiment with a high quality ogg stream, this might give you beter results due to the use of a different audio compression mask.
