The chip cares only the relative voltage difference between it's connections. It doesn't care if that virtual ground is 0V, +12V or something else relatively to some other voltage. If you decouple/shift the audio input signal properly, it will work. And make sure it is muted and doesn't make a huge pop when powering ON.
For these chips +/-12V is the minimum voltage. It will probably not be reliable or the parameters will significantly degrade below an absolute minimum supply voltage, if your power supply is not super stable/powerful.
