Testing on "Yoko Kanno - Macross Plus Original Soundtrack ~ for fans only - 13 - VOICES (a cappella version)" at different combinations ranging from default speexdrop config to q10 complexity 10 resulted in good quality compared to 16KHz wave file (which on my system was basically indistinguishable from the cd as it is just pure vocal). Which is why i posted a thing titled "sticking a speex file inside a vorbis file"
I'd upload the files, but that would most likely be questionable. Does anyone want to either tell me where to get .WAV files from to test on, or email me some of their own?
either reply to whatever address i end up sending this from, or to not_a_weirdo_just_strange at yahoo.co.uk
