Somewhere I got it in my head that I need to clip my output
signal (float*) to the range [-1.0, 1.0] before sending my
audio signals downstream.
No, just send your data out as is. The [-1, 1] limit only applies for jack
when the float audio is converted to whatever bitdepth-integer your soundcard
uses. Which is why some people have a post-fader limiter in their master
channel in ardour during recording/mix (but not during mixdown/export).
You should keep in mind that your app sounds better when it stays within [-1,
1] under normal circumstances. But you don't have to force that. Their wont be
any losses when your signals go beyond 1 as long as the audio stays within
jack.
Have fun,
