Exporting final sound mix out of the sequencer

Is there a way to render a wave file of the sound mix coming from the sequencer on Linux? I need still frames + separate sound mix. Extra points if achievable without ffmpeg, but even with would be rad.

Scene tab>Audio>Mixdown?

Yep use mixdown, but it does take awhile to complete and you have no indication as to what is happening.

Worked as advertised! Thank you guys.
