A modern Linux audio system is incredibly powerful. It makes it super easy to route audio output from an Amiga emulator into any audio application.

Sadly, AmigaOS doesn't have such a powerful audio system. Linux has come a long way in terms of audio systems, from OSS to ALSA and JACK, to what is probably the current state of the art, named pipewire. Pipewire unifies the software interfaces of ALSA and JACK - which means that now applications using any of the two systems can seamlessly be connected. Which makes it possible to just route the audio from an Amiga emulator - e.g. fs-uae - into your preferred Linux audio software. An application like QJackCtl provides a nice GUI to visually manage the connections.

An emulated Amiga provides some speech synthesis to Linux.

In this case, the emulated Amiga was used to provide some of his (her) characteristic "say" speech synthesis to an audio production created with ardour DAW.

But one can imagine many more use cases for such a setup:

- directly record Amiga music into your Linux DAW or video editing application

- real-time enhance emulated Amiga's audio via Linux: adjust stereo separation, add compression, add EQ, ...

- analyze Amiga audio output without analog interference

- experiment with multiple emulators / instances

Some of this can obviously be done with e.g. an emulator's record-to-WAV or record-to-video functions, but it's still a nice option to just be able to use Amiga's audio in real-time, without any conversion, in any audio application, and of course without the need for any additional hardware.
