Hi,
as I know there are at least three possible WMA 9 profiles: BASE, FULL and PRO. I'm trying to find some info about differences between BASE profile and FULL profile, without any success. Maybe someone knows where to look for that? Thanks in advance smile.gif

Krzysztof

WMA does not have profiles in the sense that most other codecs do. Instead WMA consists of several essentially independent codecs:

WMA Std
WMA Pro
WMA Lossless
WMA Voice

I've never heard of 'Base' or 'Full', but judging from the name they probably refer to WMA Standard.

Actually, WMASTD does have profiles but I've never heard of "BASE, FULL and PRO" in that context. The allowable audio-only profiles are:

[-profile] <profile code>
Specifies a predefined profile to use in the session.

a20_1: Profile_AudioOnly_FMRadioMono_28K (20 Kbps)
a20_2: Profile_AudioOnly_FMRadioStereo_28K (20 Kbps)
a32: Profile_AudioOnly_Modem_56K (32 Kbps)
a48: Profile_AudioOnly_NearCDQuality_48K (48 Kbps)
a64: Profile_AudioOnly_CDQuality_64K (64 Kbps)
a96: Profile_AudioOnly_CDAudiophileQuality_96K (96 Kbps)
a128: Profile_AudioOnly_CDAudiophileQuality_128K (128 Kbps)


Descriptions are Microsoft's not mine.

BASE, FULL and PRO may be someone's reference to WMASTD (Standard), WMALSL (Lossless) and WMAPRO (Professional). In any case if you've decided to encode to WMA, that would be the first choice you'd need to make. Post back on what is your intended use for the files and you should get some suggestions.

OK, thanks for ensuring. I had some doubts about WMABASE and WMAFULL rather in context of DLNA, but it looks that it's just WMA STD with different bitrates.

I googled around for DLNA, and it looks like the BASE and FULL profiles just refer to the bitrates allowed for streaming to some DLNA devices, I don't think they're WMA specific since some things work with AAC as well.
