Hi. Thanks for the patch. I suspect the issue has been here for a longer
time, if only on one branch of the conditional build:

#if CONFIG_SWRESAMPLE
…
                 const double sample = fabs(swr_samples[i * nb_channels]);
#endif

versus

             const double *restrict samples_ch = &samples[ch];
…
                 const double sample = fabs(samples_ch[nb_channels * i]);

Anyway, the fix looks good to me.

Niklas, it has become mostly your code, what do you make of it?

Now that n8.0.1 will be tagged soonish it would be great if this fix could be included.

Regards, Tobias
