Abstract
Waveforms are the most important precision observables in modern studies of general relativity. I will discuss how waveforms in gravitational scattering are closely related to scattering amplitudes, touching on how to extract classical observables from amplitudes and the double copy. Finally, the recent computation of the next-to-leading order waveform has revealed a number of interesting details including the importance of generalisations of amplitudes, and BMS dependence of the waveform.
