Full Version: Converting to WMA mono using Foobar2000

Hi to all,

I need to convert most songs I can in mono at rather low bitrates and it seems the best codec is WMA (I need to put the songs on my mp3/wma player and use it at the office, with speakers very far from each other, so it's better a mono solution)

Well, I set up Foobar as suggested here http://www.hydrogenaudio.org/forums/index....showtopic=47759

but I can't figure it out how to convert the Wavpack files (stereo) in WMA mono using Foobar in one single passage directly (I end up with stereo wma files every time!)

Can anyone help me posting the complete WMA parameters one can use?

Thank you.

Hey guys,

can't anyone help me?

I tried for example:

Encoder: C:\Program Files\Windows Media Components\Encoder\WMCmd.vbs
Extension: wma
Parameters: -silent -a_codec WMA9STD -a_mode 2 -a_setting Q75_44_1 -input %s -output %d

which in theory should give me a 1 channel (mono) audio file, but I also obtain a stereo file.

Please shed some light!

Thank you!!!!

Prayan

Perhaps no one has responded because WMA is a pain in the arse to use. So I wouldn't be using it. My advice, convert to mp3.

I just converted a FLAC file and a WV file to lowbitrate mp3 mono using foobar. This was my command line within foobar:

CODE
-a --noreplaygain -V 8 --vbr-new - %d


Cheers!!

Prayan, Q75_44_1 is not an allowed setting for quality based WMA9STD encoder. In that mode you can encode only to stereo. Use the switch -a_formats to list all available parameters. Here is only the part for quality based:
CODE

Quality-Based VBR Audio Mode :
    WMA9STD : Windows Media Audio 9.1 (WMA9STD):


        Argument                Quality         Sampling rate       Channel
        ------------------------------------------------------------------------------------
        Q98_44_2                Q98             44                  2
        Q98_48_2                Q98             48                  2
        Q90_44_2                Q90             44                  2
        Q90_48_2                Q90             48                  2
        Q75_44_2                Q75             44                  2
        Q50_44_2                Q50             44                  2
        Q25_44_2                Q25             44                  2
        Q10_44_2                Q10             44                  2


Hope this helps!

Hi Prayan, this line works for me in Foobar2000.

c:\progra~1\wi15da~1\encoder\wmcmd.vbs -input %s -output %d -profile a20_1

This will return a 20kbps 22050Hz mono file.

cheers,

Hi,

this line works for me too but I want a higher quality, so I tried to edit the wmcmd.vbs file but I get an error from foobar. I think I'll turn to mp3 even if I'm pretty sure that wma at lower bitrates should be more efficient.

Thanks to all!!!!

The highest quality (bitrate) that you can get from WMA for mono files is CBR mode 48_44_1.
