No need to worry. The Källa backend is programmed carefully to use the most musical methods to transfer the data from the control point to the decoder framework. Airplay 1 and 2 refer to different sets of methods and handshakes between the client and server to enable different features. Källa is optimised only for the most musical combination of options and transfer methods and cannot be labeled as ”Airplay 1” or ”Airplay 2”.
Thanks jajo,
so with Källa there is never the above mentioned compression from 16/44.1 to AAC256?
I don’t mean to sound rude in any way, but the question is really quite irrelevant when we are discussing the best way to transfer the music signal from the control point to the decoder framework.
A signal source like Källa is a very complex system where many parameters will affect the end result. The bitrate of the audio stream is important, but not in the sense that most audiophiles think (that higher is always better). Bitrate/format is just one small part of a critical chain of events where every step must be selected based on the end result - which is the enjoyment you get when listening to music.
This is the best explanation of bitrate I've seen. Montgomery is the man behind the ogg vorbis used by Spotify.
Thanks. I've used it to satisfy my curiousity and prove that my speaker frequency range is within spec. I'm also going to see if it can help me track down bass resonances in my room. I also discovered that entering 3 instead of 30 makes the page take a loooong time to respond to the 'stop' button (perhaps not surprisingly ...)
