Great tests GFR
And now, one more test to add
Go here:
http://homepage3.nifty.com/blacksword/
Download the latest oggenc2.exe and all necessary dlls (so you have the latest), and encode those clips like this:
C:\testing>\vorbis\oggenc2.exe -b 48 --advanced-encode-option impulse_noisetune=-15 C:\downloads\youcantdothat.flac -o youcantdothat.ogg
That's my command line, because I have oggenc2.exe installed at C:\vorbis
NOW ABX that, and see your results
But note the file size compare to a 48Kbps AAC+ file, but I can't hear any artifacts on the Ogg
The average bitrate is 48Kbps (-b 48 ) as shown on the command line, but there are no MIN/MAX bitrate restrictions, so on complex music the bitrate will go high, and way down on silence spots.
Anyway, the file size is WAY smaller than the MP3 file encoded as -V 6 --vbr-new but audio is as good, or better
MP3
601,389KB
Ogg:
194,802KB
AAC+
183,217KB
The AAC+ is just a little smaller than the Ogg, but the Ogg is almost identical to source in quality
And I can ABX that 48Kbps AAC+ and hit 10/10, but not the case with the Ogg or even the MP3
Give that a shot
