Audio is quieter when rendered than in Vegas

[Steve Rhoden]

Probably because you are rendering out with different settings,
it gets slightly altered during the conversion process.

Hi Matthew,
Steve is totally correct. Generally you have to make sure that your master is at the desired level before you mixdown/render. Usually the problem is the opposite(avoiding clipping) There is a chance you could have some phase problems if you are mixing down multiple stereo tracks. Sometimes they cancel each other out. If you set up the project like you would on a hardware mixer (all tracks mono) and then mix down to stereo, it would clear things up.

There’s also the possibility that it is being handled differently by whatever program you are using to play it back. Put the rendered mp3 clip back in vegas and see if the audio levels are the same as the project it came from.

I have found a difference depending on what sound mapper is used. The standard windows sound mapper or the directsound surround mapper. The directsound mapper was quieter. Vegas lets you choose the mapper and my playback software, Media Player Classic, also allows this. When the two were different I noticed something.

That’s a good point Norman. I’d forgotten about that. I am using Edirol and M-Audio interfaces that use ASIO drivers to output the sound, then I go to KRK or M-Audio monitor/speakers. Pro audio interfaces usually come with ASIO drivers so the audio quality is greatly improved over a stock motherboard or soundcard. ASIO also helps a lot with computer latency(delay) when you are overdubbing.
