The solution to use largely depends on your requirements. There is no universal answer to this one.
Some of the points to consider: max output current? Isolated or not? How low should be "low noise"? Do you really need voltages higher than +/-Vbat or even +/-(Vbat/2) ?
If +/-(Vbat/2) is adequate, implementing a virtual ground is a popular approach, it's simple and if done properly, adds little noise. The TLE2426 (
http://www.ti.com/product/tle2426 ) is a great device for instance (up to +/-20 mA). Of course there are numerous such ICs, and you can also implement that with an opamp (as long as it can source and sink enough current for your application, but you should be careful about stability).
If +/-Vbat is OK, you can use an inverting regulator (charge pump or an inverting buck/boost) to generate -Vbat.
You can also consider the following parts depending on the input voltage requirements:

Absolutely not exhaustive.
Another (obvious?) solution to use, but not necessarily practical or low-cost depending on the application, is using two batteries in series (that can be followed but LDOs if needed). For audio stuff, this is often the lowest noise of all.
