Here is another idea (not sure if it's been mentioned yet):

Store the audio in the display format: Apply a function while
recording, and apply the inverse function while playing.

I thought about [pow 0.25] for recording and [pow 4] for playback
first, but this will flip the negative parts of the waveform to the
positive range. Maybe you come up with something that actually works.
