  • I have Music but voice and vocals are Lost In Space????

    Vegas 5 –

    I’ve had a complaint about a DVD with no “vocal sound, but they can hear the music.

    I’ve tested everything here and we have attributed it to the player??

    Encoding in Stereo DVD -31 DB… L & R etc. using Ed Troxel’s recommendations to keep the audio levels up on DVD’s. All DVD’s play fine here in all DVD players and computers, except I need to put my Sony Receiver out of PLII MOV mode and into stereo.

    Now… here is the wierd part, I just encoded a WMV 9 file for streaming… just like every other. I keep the picture size small and I keep the audio bitrate down to 16kb mono to save bandwidth for the video.

    For the first time, I hear ALL Music and NO vocals…. Almost like I used some kind of vocal filter.

    There is a lot of bass in the song… but why would the vocals be in reverb way off in the distance (Almost totally non-existant) and the music clear as a bell.. (playing from my hard drive… not streaming)

    This is what one of my clients was talking about on a DVD

    Any Clues?

    Thanks Wayne

    OK, i tried compression on the audio track and still no help – then increased audio data rates for a 100KB stream to the minimum for stereo audio (had mono B4)… now its all there.

    this is the first clip[ that I’ve had this problem with in WMV streams so I guess I’ll go with a stereo stream from now on, but still wondering why one of my clients had such low audio on a DVD other than perhaps the DVD player(s) – parents and daughter both have the same problem –

    All other clients do not report problems. suggested they look at set up menus on their dvd players for audio playback –

    any suggestions there?

    What about audio track compression? – does anyone use compression on their DVD’s with the standard options available in Vegas – this was my first try at audio effects like this –

    what would be the recommended settings if audio compression is advisable!

    thanks again to all

    Is it possible you’ve set your project up for 5.1 surround and your voice is going to a center channel? Set it up for stereo.

    Is it possibly a mono-stereo compatibility issue? This usually occurs on playback when you have stereo music and mono voice playing back on a mono device where the channels are summed, if a wire is crossed or the two channels are out of phase with each other mono content will be inaudible or quite low, and stereo content will be less affected.

    Clear as mud?

    Also, if phase is reversed on one channel stereo playback can sound quite wierd as well.

    How does it happen? Usually this is a hardware, not software issue, where the + and – wires on one channel are reversed. You’d check by taking an ohmmeter to each wire in use and seeing if each pin is wired to the correct pin on the other end.

    It can also happen in software (uncommon) if any “phase” switches have been inadvertantly enabled. (right click on clip, switches, phase). Also, strange phasing problems may occur when the same content is on duplicate tracks and there is any time offset between them.

    But this doesn’t exactly sound like what you’re experiencing… but it sure doesn’t have anything to do with compression, and I’m a little confused by your mention of WMV. If you’re preparing for DVD you would either output a DV-AVI for compression by DVDA, or an MPEG2 and separate audio track.

    to answer the question about windows media – I also rendered part of the project as windows media for streaming on the web at 100KB.

    That was after rendering the mpg and AC3 files.

    everything was fine with the windows media after i bumped the data rate up to about 20kb/s — it was set at 16 kb for audio (who knows).

    AS far as the DVD’s go, I was looking for something for MONO setting… without rendering for Center Channel only… I suspect that would really screw things up.— but maybe not???

    Right now I am rendering stereo DVD (L&R) only. but it definately plays out of the back channels and hardly out of the front when in anything but 2 ch stereo on the RXVR. any dolby modes it’s all rear channels… weirdest thing i have ever seen.

    Just to check, I just took one of Gary Kliener’s DVD’s down and it plays fine – Through the center channel on most of the dolby audio options… (listening to voice ) either from the center channel or from the 2 fron L&R channels, on stereo L&R onlu, it’s fine.

    YES, My speakers are hooked up correctly… just in case someone is wondering if that’s it!…

    Should I use MONO Center only?

    It does sound like a phase problem to me also. Try playing the stereo version (that you said worked) in vegas and click the “sum audio” in the master bus…I can’t remember the exact name of the button since I’m not at my editing machine. But if you loose the vocal this way, I’d say that would pretty much nail it down do to a phase problem.
