In the light of recent developments in core-collapse supernova theory (Burrows et al. 2005, astro-ph/0510687) I will review the current status of supernova gravitational waveform theory and present the wave signature imprint of the new core-acoustic-explosion mechanism. The core g-mode quadrupole emission dwarfs any emission process such as rotational bounce or post-bounce convection previously considered. We surmise that, even without rotation, galactic core-collapse supernovae will be observable by first-generation LIGOs and next-generation tuned bars.
