Not only does it handle it fine: but most players will downsample the 96k audio for playback on non 96k able hardware. (24bittage isn't an issue as Vorbis is 24bit internally, thus all players will produce good output from 24 bit input...

Someone sent me a question late last night and I briefly looked at his file this morning and couldn't figure out the answer, so I'm posting here. A friend has a a ~275MB 24 bit, 48khz stereo wav file of rock music that when compressed using flac level 8 gives a flac file under 110 MB in size. When I dithered his file to 16/48 and converted that file to flac, the resulting flac file was

24bits are only 14% more information than 16bits, not as much as it looks. I presume the downsampling introduces some noise which compresses poorly (bigger residuals) and pretty much outweighs the advantage. This does not happen with a lossy codec, if the same error tolerance is imposed on each stage: a 5...

Hi: I am trying to convert an avi file to an ogg file. The avi file is 12 frames /sec, resolution 1280x768, 24bits, compression: Cinepak Codec. I got the following message.

...y Sound Consulting P.S. Nicholas, where did you come up with that 14% figure? A 16-bit file is 33% smaller than a 24-bit file, or a 24-bit file is 50% larger than a 16-bit file. I can't find any math that works out to a mere 14%. On Dec 2, 2010, at 07:10, Nicholas Wilson wrote: > 24bits are only 14% more information than 16bits, not as much as it > looks.

Commit "f4bd542bca drm/fb-helper: Scale back depth to supported maximum" uncovered a bug in the cirrus driver. It must create its own primary plane, using the correct format list, depending on the bpp module parameter, so it is consistent with mode_config->preferred_depth.
