I've just started using Astiga and I've noticed a persistent crackling/static sound in the background when streaming. It's mostly notable at the end of songs or in less loud songs, but it's always there.
That's odd. Is that using the web app or the Android app? If the former: using every browser? And what is the file type?
Without Astiga premium, Astiga will always play the audio files as-is (so bit-for-bit as you uploaded), and it doesn't do any post-processing (unless you turn on the equaliser). With Astiga premium, it might convert them to FLAC (if it's not one of the file types that your browser can play).
Never mind, I think I was being a total idiot. I think it was just an effect the album used.
