I do a lot of audio in Vegas, primarily voiceover. For the sake of more efficient file sizes, I render to mono whenever possible. Historically, Vegas has never allowed me to render to a mono mp3 in a resolution north of 128K. I'd like to do mono in 192K and even 320K for some clients at their request.
Any way to accomplish this? Or is there any plan to allow mono renders in higher resolutions?
With Vegas Pro: No. But if you have Sound Forge (Studio or Pro) available, this allows for 320 kbit/s mono MP3 export.
I have Sound Forge Pro 11, and I don't see any way to make it mono there either.
I just tested the 320 kbit/s output from Sound Forge Studio 12.5. Seems like this is a new feature of version 12.
"Awave Audio" (http://www.fmjsoft.com/awaveaudio.html#main) will satisfy your requirement up to 320kbit/s.
Try for free. If happy, buy the full version for €16 / $20.
DO NOT RE-ENCODE MP3; just export your originals as WAV then encode once to desired compressed format.
It sure would be nice if it could be directly outputted that way without having to render to wav and then re-save it in the desired format.
If your only concern is file size, do you realize that a mono file at 192k will be the same size as a stereo file at 192k? (assuming the same audio source). In fact, at any bitrate the mono and stereo will be the same size with the same bitrate.
For high res MP3 files, I like the LAME encoder with the rc3 UI. which supports mono/stereo CBR MP3s to 320kps.Via the preset file other parameters can be adjusted such a quality, HP/LP filters, ect.
Yes a mono or stereo MP3 will be about the same file size, but the mono 192kbs file would have the equivalent quality of a stereo 320kbs, or... a mono 320kbs would have the theoretical resolution of a 740bps stereo MP3. In my spoken word file tests, a 48/16 PCM and 320kbs CBR MP3 totally cancel out in a polarity test, which indicates little to no audible quality difference in a spoken word mono file. Despite the high res,, I would still recommend recording PCM files initially.
