Yes, it’s possible with the United OpenLib of Sound (UOS). Fred has
created an excellent library and it works very well. I’ve personally
tested it on multiple platforms, and so too have others. The latency is
very low when used with LCL, and even lower when used with fpGUI.

You can find the code here:

It includes a couple of example applications too.

There has been quite a few discussions of UOS with Fred in the Lazarus
Forums too.
