Vegas 13 Audio Problem with Izotope

Randini wrote on 2/24/2016, 12:21 PM
On a stereo audio track when I right click/channel/combine it creates a MONO track which is great. Then I open within Vegas Izotope RX and it makes the audio about an octave lower in pitch. Now in Vegas 11 this did not happen. Any fixes?

NOTE: The ac3 audio is causing this but again did not happen in Vegas 11. When I render the audio to a Mono Wave RX does not have a problem.

I'm not seeing this behavior in V13 with the trial version of RX Plug-ins (De-hum, de-noise) etc or with iZotope Elements. I don't have the full version of RX .

I bring in a video mp4 that has Ac3 and right click/open copy in editor. RX opens and the file works. However if I make the audio file in Vegas a Mono by right clicking/channel/combine then when I open the editor RX I get the octave pitch drop.

Sorry for my poor english.

Well, seems to be no fix. I just re-render to mono wave and bring it back into Vegas and all is good. Just another step to do. Funny how upgrades are sometimes worse in areas.

Here's the reply I got from SCS regarding the same problem, ie right click converting 2-channel track to Left only or right only. opening this mono track in Sound Forge give the octave decrease.

SCS:
The reason why those symptoms are occurring is because the file being opened in Vegas still being effectively a stereo file (which you are only using one channel of) is at twice the sample rate of an actual mono file (due to the mono file only having one channel).

I recommend opening the stereo track on the Vegas timeline in Sound Forge, turning it into a mono file in Sound Forge, then re-importing that file from into Vegas after saving it out of Sound Forge. This will yield the end result of a mono file with a single wave at the correct sample rate (rather than at half sample rate).

I got myself into this situ a while back. I didn't know the answer, and thanks to you I now have a solution!
