Is Ogg Vorbis dying? - Page 3

I'm not into all this vorbis stuff, but "q6.0" sounds like VBR, so, again, this is not 192kbps. The same thing goes for AAC.

5MB/7% is still a huge and impossible difference. There is some overhead of MPEG-4 container, but it is certainly not that large (and OGG container also has some overhead).

OGG is known for having better compression for the same SQ compared to MP3, I confirm it's VBR and q6 is around 192kbps.

That 'known' statement hasn't been true in years. In low kbps files, that may be so, but otherwise, it simply isn't proven in any public tests anywhere.

Ogg Vorbis has a place for me... I use it on my DAP for audio books. I turn it down to the lowest VBR setting possible for maximum compreeions and space saving. It is still standable, and speech is intelligible. It seems like when I do this with MP3 is downsamples right away, cutting some of the higher frequencies, and altering the sound. I thing OGG is superior because it compresses better, and that becomes even more noticable at lower bitrates when it does not have to downsample so far.

OGG: 32kbps 44.1khz

MP3: 32kbps 22khz

When it's a question of sound, it's always subjective, but I suppose it's easier to find differences with low bitrates. People from hydrogenaudio did a test some years ago.

The methodology and results.
