VoxWare MetaSound Audio CoDec

Voxware provides high-quality sound using low- to mid-range bit rates. It comes with a variety of mono and stereo audio formats to choose from depending on your network bandwidth. It is also suitable for encoding mono voice-only content at extremely low bit-rates.
MetaVoice works far FAR better than MP3 and even WMA at very low bit rates. You can get very good speech quality at 2kbit/sec! (Note I said "bits" not "bytes" - you can't touch that with MP3.)

It'll do soundtrack noises pretty well too, although it can get muddy if there's too much going on. Using the MetaSound codec and upping the bit rate to a whopping 8 or 16kbit/sec will fix this. The best part is there are no restrictions on the Voxware codecs - you can use'em in pretty much anything and they'll play.


- Audio Codec Tag 75 may be requested when VoxWare MetaSound Audio CoDec is missing.

How to install VoxWare MetaSound Audio CoDec:

- Uncompress the files from "VoxWare_MSA_CoDec.zip" archive, right-click on the "voxacm.inf" file and select Install.

What the Heck? I was so pleased to be able to finally play a concert video hidden on a CD from 2000--after following advice and downloading KMPlayer. But it only worked once!! I can not recreate the conditions, nor can I get it to work on XP Windows Media Player. That device continually tells me that I do not have the correct codec.

Like Christina (15 July 2009), I would like to have WMP recognize the codec. Tweak Tools from K-Lite also could not help. I have been able to get the VIDEO to play in WinAmp, but with NO AUDIO... HELP!! PS. Does all of the advice about .inf files and copying to the C: drive no longer apply now that we have .exe files?

I could not get any of the advice about "voxacm file set up," nor "Run as Administrator" to apply to my situation. Is that advice out of date?

Doesn't do anything and there are no inf files.

The other comment about audacity is totally incorrect. It will not import/play undf. try the tutorial "flight of the bumblebee" from monkeyseemonkey do site.

Stupid YouTube using crappy bloody codecs!

I went on another way. I have installed K-Lite Codec Pack on my system and went to Codec Tweak Tool and there enabled all Vox codecs in the codecs tree. And sound appeared! :D
