Perhaps Im the only one noticing this, but I think the audio file handling in LW9 could be better.
Im using Mac version and although I try to set up the start frame of audio clip, it just starts from beginning always. The attempt to set the start frame don't have any influence.

And also, it keeps starting the audio file from beginning if I move frame slider to frame 50 for example.

This is first time to use the audio for lip syncing so I'm not sure whether this is a bug of 9.6 or lack of my knowledge.

Can someone confirm this?

Hmm. That used to be a problem with the Mac audio handling, but I thought it got fixed... are you having these problems with 9.6?

I don't have any suggestions for Lightwave audio on the mac - I gave up long ago, and haven't tried it since things were supposed to have been fixed in 9.6.

However, if your animation needs are pretty basic (morph based lipsync), I developed something of a pipeline using Moho exports from Papagayo (http://www.lostmarble.com/papagayo/index.shtml) (Yolo (http://yolo.sourceforge.net/), JLipSync (http://jlipsync.lamhauge.dk/), or similar) and some javascript utilities to convert the lipsync keyframes into Lightwave envelopes (including custom phoneme sets, for the likes of JLipSync that use a wider range than just the Preston Blair). Using a seperate app made my life a lot easier - playback is instant, changing timing is a snap, and though it requires a largish number of files for the envelopes, it's still reasonably easy.

(and a hint - you can use Fluid (http://fluidapp.com/) to package webpages like these utilities as apps in your dock. Just grab the "Open the..." link addresses on the web pages above for direct links to the HTML documents)

Granted, this does nothing if you need to sync LW animation keys up to other audio cues, sound effects, etc. It's also entirely unhelpful if you're doing real lipsync, as opposed to phoneme morphs. If that's the case, please forgive this waste of time. :D

Edit: Eh, why not go ahead and include the Fluid-packaged pages? They include custom icons to match LW! Hope someone finds them useful. :) Just keep in mind the original links above have a lot more detail into the script operation, it could be helpful to review that first, just in case.
