If the position file is setup correctly (and if you're using a recent version of animtools) then sounds
will be played during penetration. If this isn't happening then please share some technical details so that we can troubleshoot the problem.
@Konashion did not include any pelvic sex noises in the game, so
@sby's code will simply play oral noises (lip contact, licking, etc) at appropriate moments. You can reconfigure animtools to make these noises occur more frequently.
If you want more authentic noises then
go find them. Collect a set of MP3 files and write up a description of when each one should play (first anal penetration, vigorous motion, ejaculation inside body, etc). Then post your work or contact
@sby directly and ask him to incorporate it into animtools. For best results, try to ensure that your audio files are clean (no background noise) and that the volume levels are consistent. Don't expect
@sby to remix your audio.
If you'd prefer to hear feminine vocalizations instead of meaty organic noises then you can configure animtools to enable them. Recent versions of animtools include several voice options, collected by
@DrZombi. They're disabled by default, in order to keep the SDT user-experience consistent
(players might be disturbed if they update a mod and then discover that the game has begun to emit orgasmic shrieks).
If you don't like those voices then you can follow
@DrZombi's example -- collect a set of moans and gasps from your prefered source, add some notes, and then share your work.
