1. Windows Media Audio 9.2 - 56 kbps, 44 kHz, stereo 1-pass CBR
2. Windows Media Audio 9.2 - 16 kbps, 11 kHz, stereo 1-pass CBR
3. Windows Media Audio 9.2 - 8 kbps, 8 kHz, stereo 1-pass CBR
4. Windows Media Audio 9.2 - 40 kbps, 22 kHz, stereo 1-pass CBR
5. Windows Media Audio 9.2 - 44 kbps, 44 kHz, stereo 1-pass CBR
6. Windows Media Audio 9.2 - 40 kbps, 48 kHz, mono 1-pass CBR
Most WMA encoders couldn't do these 6 modes above. I need to change existing modes? Or to make new modes from scratch?
Many greetings to ask this question ASAP!

Those are normal CBR, any WMA encoder can do them.

IN DIRECTSHOW ENCODERS LIKE NCH SOFTWARE WAVEPAD OR SWITCH.

I believe the windows media sdk had a tool for defining new directshow encoder profiles.  Not sure if it still works with modern windows version.

You could do it via commandline:
Code: [Select]
cscript.exe wmcmd.vbs –input inputfile.wav –output outputfile.wma -a_mode 0 –a_setting 56_44_2
-a_mode mode_number
Specifies the encoding mode for audio content. You can use one- or two-pass CBR encoding (-a_mode 0 or -a_mode 1, respectively), or a VBR encoding encoding mode: quality-based (-a_mode 2), bit rate-based (-a_mode 3), or peak bit rate-based (-a_mode 4). For more information, see Using CBR or VBR encoding.

-a_setting bitrate_samplerate_channel
Specifies the audio bit rate, sample rate, and channel setting for encoding. Or, if you are using the Windows Media Audio 9 Professional or Windows Media Audio 9 Lossless codecs, -a_setting also specifies 16- or 24-bit encoding, as bitrate_samplerate_channel_bitspersample. Use the -a_formats option to view the settings supported for each codec. If you are using the Windows Media Audio 9 Voice codec, the default value is 12_16_1. If you are using the Windows Media Audio 9 Professional codec, the default value is 128_44_2_24 (unless you are also implementing a quality-based VBR session, in which case the default is Q75_44_2_24.) If you are using the Windows Media Audio 9 Lossless codec, the default is Q100_44_2_16. If you are encoding uncompressed content, the default value is 705_22_2. For all other scenarios, the default value is 64_44_2.
