Confused About An Old WMA Codec

Hi everyone,

This is very confusing to me. I know that WMA goes back to WMA V1 and WMA V2. I have encoded to WMA V2 but never been able to find a way to encode to WMA V1. But, let's get to the point here

On this site: http://www.real.com/msaudio/ Real does a comparison of RealAudio G2 codec and MS-AUDIO. They have some samples to listen so when the MS-AUDIO samples opened in WMP I decided to see what was in the properties. And, sure enough, it said Microsoft Audio Codec was the codec used.

I know it's old but I'd like to be able to encode with MS-AUDIO but I have no clue how or where to get what I need to do that.

Any suggestions or ideas?

I'm pretty sure thats just a WMA file of some kind.  The ffmpeg wma decoder is able to play it at least, and its WMA v1/v2 only.

Thanks. What I'd like to do though is encode with the same codec they used. I don't know what program or method they used to encode those. I do know that they made that test obviously a long time ago when MS-AUDIO and REAL G2 were the big two.

I thought I could use msaud32.acm to get WMA V1 but that never works with any program i've tried and I don't know if WMA V1 is the same as what they used "Microsoft Audio Codec".

Sadly(!), the old encoders don't seem to be available any more on the MS website.

I bet someone has one somewhere, though I doubt it would be legal to distribute it.

Cheers,
David.

Since they did not post encoder versions, you would not be able to duplicate the test anyway.

If you can install Windows Media Player 7, I believe it recorded in WMA (and wmp 7 = wma 1)

Alright, I'll see if I can install WMP 7. I have XP 64-bit edition so it won't be the easiest task but I'll give it a shot.

Thanks everyone.

I think [JAZ] is right.  WMP 7 was the first time that Microsoft was advertising that their WMA encoder at 64kbps was equal to Lame (albeit a much older version of Lame at the time) at 128kbps.  WMP 7 also seems to be the first release of WMP that allowed people to rip their audio CDs to WMA.  Then again I could be mistaken.  Wasn't WMP 7 the one bundled with Windows ME?

Edit:  I was able to find a link to download WMP 7, it is located here from Cnet (download.com).  You might be able to pull the encoder out of the installation package or something.  The only problem with installing WMP 7 is that it has limited OS support.  I think you must be working under Windows 98, Windows ME, or Windows 2000 but I am not 100% about that.

Okay well I did extract the DLL's needed for encoding and it is all working well.

Thanks everyone.
