I encoded the Beatles sample and the waiting sample with -V 6 --vbr-new.
I still have not tried to ABX the Beatles sample - I can't hear any flaws so I would really be guessing from the start. I'll try this at home with better headphones (I'm using earbuds now - I'm at work :)). edit: This Beatles song is hard to encode because it is not a "natural" stereo - you have instruments hard panned to each channel. That ruins any space saving you might have had with the use of joint stero or parametric stereo etc. If I'm not mistaken in the USA these early Beatles records were only released as mono. I tried to ABX the waiting sample: foo_abx v1.2 report foobar2000 v0.8.3 2006/03/17 09:20:33 File A: file://E:\downloads\mais\Waiting.flac File B: file://E:\lixo\001 Waiting.mp3 09:20:33 : Test started. 09:23:03 : 01/01 50.0% 09:23:21 : 02/02 25.0% 09:23:37 : 03/03 12.5% 09:23:53 : 04/04 6.3% 09:24:10 : 05/05 3.1% 09:24:16 : 06/06 1.6% 09:24:32 : 07/07 0.8% 09:24:53 : 08/08 0.4% 09:25:02 : 09/09 0.2% 09:25:18 : 10/10 0.1% 09:25:22 : Test finished. ---------- Total: 10/10 (0.1%) I was surprised 8O Those breathing noises are really hard on the encoder :D I must admit I'm being very picky. If I just sit back and enjoy the music, it's a good sounding encode. |

The Beatles sample with lame -V 6 --vbr-new.
foo_abx v1.2 report foobar2000 v0.8.3 2006/03/17 09:41:32 File A: file://E:\downloads\mais\youcantdothat.flac File B: file://E:\lixo\002 youcantdothat.mp3 09:41:32 : Test started. 09:45:23 : 00/01 100.0% 09:45:43 : 00/02 100.0% 09:46:03 : 00/03 100.0% 09:46:22 : 01/04 93.8% 09:46:51 : 02/05 81.3% 09:47:35 : 02/06 89.1% 09:48:09 : 03/07 77.3% 09:48:39 : 03/08 85.5% 09:48:55 : 03/09 91.0% 09:49:19 : 03/10 94.5% 09:49:32 : Test finished. ---------- Total: 3/10 (94.5%) It's definetely transparent for me. I'll try with a different pair of headphones later. |
Great tests GFR :D
And now, one more test to add :D 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 :arrow: 601,389KB Ogg: :arrow: 194,802KB AAC+ :arrow: 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 :cool: Give that a shot :D -kwag |
