.WAV from Vegas > Cubase = Time Stretch (Too Fast)

Soniclight wrote on 8/30/2010, 2:11 PM

I can do much more polishing of audio in my Cubase SX and so I un-grouped the audio in Vegas from a shot taken with my Canon HV30, exported it as basic 16 bit, 41 .wav.
But once put into Cubase, it's slightly chipmunky -- sped up.

Straight export from Cubase reduced the file size from 3,327 Kb to 3,058 Kb which explains why it's at a slightly higher pitch.

The other way around, no problem: When I export music as .wav from Cubase and put it into Vegas, no pitch shift or length change.

I've never run into this before with importing .wav files into Cubase, so it must be something in Vegas or something I'm doing in Vegas that's causing this boo-boo?

Help appreciated.

Whats your project Hz in Cubase? Sounds like thats set to 48KHz...

Soniclight,

According to the Cannon U.S.A. website, your camcorder records audio in the following formats:

DV: 16 bit (2ch) 48 kHz

You simply have to export from Vegas in the "exact same" format the audio was recorded in. Then as essami mentioned above, set up your Cubase SX project with the same format (e.g. bit depth & frequency) and you should be OK.

I forgot to mention that if for some reason the orginal audio was lost, you can fix the "exported" audio in Cubase SX by performing "Pitchshift" & "Timestretch" operations.

Thanks for all your responses.

Indeed, ye wuz right -- the Cubase SX3 project in which I imported said 41 Khz audio is in 48 Khz.
So time to start a new project Cubase or change the Vegas project and/or render-out settings.

I'd rather get it all to match from the front end between these two apps -- because messing around with time-stretch may get a good approximation, but bit-by-bit spot on lip sync is important.

First, don't export the audio at 44.1kHz. If it came originally from a video file it will have been recorded at 48kHz and you should keep it at that sampling rate unlesss there is a good reason to change it. Export it at 48kHz and you should not have the pitch shift problem in Cubase.

Second, you should be able to do in Vegas anything you can do with the audio in Cubase - there should be no need to export audio to another application for "polishing". Vegas was originally an audio-only application and it is well able to handle anything you may think you need Cubase for. (The only important exception to this is if you need to use MIDI, in which case you will need something other than Vegas - Acid or Cubase, for example.)
