An introduction to computer audio
JRiver has a plethora of options.
Most of them are documented in the JRiver Wiki.
But JRiver is a small technology driven company so they rather develop instead of keeping the documentation up to date.
Parts of the Wiki are therefore incomplete or a bit outdated.
But I must admit I rather see them develop new features than maintaining the Wiki.
There is also a very responsive forum.
Use the menu on the left to view all the options.
