Two audio files in SL - can't adjust volume
Help! I have a beginning slide and closing slide in SL360 where I have some background music (separate mp3 file) playing while voiceover (a second separate mp3 file) is playing on top. I have adjusted my music file in Adobe Audition to be very quiet so it doesn't overpower the voice. However, once I preview it in SL or publish and play, SL seems to force the music file to match the volume level of the voiceover file, so it ends up overpowering the voiceover. I have taken the music file down to an almost barely audible volume, but still I run into the same problem. When I reduce the volume to almost nothing in Audition, then you can really tell that SL is compensating because it plays in SL with a loud fuzzy background sound--the lower the volume in the external mp3 file, the louder the fuzz in SL, reinforcing the idea that it has been cranked back up once inserted into SL. I've tried using the SL Audio Tools, such as reducing the volume (significantly) in Audio Editor but even though I see the wave form shrinking, indicating a reduction in volume, once I preview it or play it in published format, it is still as loud as ever. I've also tried the Low setting in Audio Volume in SL, but I don't notice any difference with that either. I just installed all the latest two SL updates to make sure that wasn't the issue. But it didn't affect this situation. Any ideas?
