Related to this, https://bugzilla.gnome.org/show_bug.cgi?id=794411 was
just filed recently.

There is an antialiasing filter in audioresample, and it is also
configurable:
https://gstreamer.freedesktop.org/data/doc/gstreamer/head/gst-plugins-base-libs/html/gst-plugins-base-libs-GstAudio.html#GST-AUDIO-RESAMPLER-OPT-CUTOFF:CAPS

There are also lots of other parameters of the resampler that can be
configured, not all of them are exposed on the element though. If any
are missing for you, feel free to send a patch or file a bug about it.
