The two arguments should have the same rightmost dim, but may otherwise be arbitrarily broadcastable.

Letting ``m = signal.size(-1)`` and ``n = kernel.size(-1)``, the rightmost size of the result will be: ``m + n - 1`` if mode is 'full'; ``max(m, n) - min(m, n) + 1`` if mode is 'valid'; or ``max(m, n)`` if mode is 'same'. :rtype torch.Tensor: fullr validsamezUnknown mode: {})rr.)rmaxmin ValueErrorformatrrr) signalkernelmodemrtruncate padded_size fast_ftt_sizef_signalf_kernelf_resultresult start_idxs rconvolver)(s(  BA BA v~q519 q!9s1ay(1, q!9+224899a%!)K!+.MFm,HFm,H("H 8} -Fx'A-I #y9x#777 88)r)torchtorch_audiomentations.utils.fftrrr rr)r*rr.s 7@)9r*
