Wanting to recreate voice effect

I have been working on a little mini-movie featuring a new alien race I drew up. I was trying to figure out how to do their voices, when I found this.

Could anyone tell me how to recreate the voice effect found here (slight vibrating burr in voice, with subtle echo behind it)? It seems like it should be simple, but I just cant seem to get it… Thanks!

That’s reverse reverb. Reverse the track (i.e. turn it backwards) apply reverb(eration), then reverse it back the right way round, e.g. here.

Reverb(eration) tips here … https://forum.audacityteam.org/t/good-gverb-settings-for-song-vocals/13355/1

For Brrr effects you could try ring modulator* (download plug-in here) or vocoder which is shipped with Audacity (see bottom of “effect” drop down menu) .

[NB: more that one effect has been applied to create the Youtube alien voice ]

[* IMO there is ~200Hz triangle modulation producing the “Brrr” ]
