...f audio data at common sample rates anyway? Does it make sense to use FLAC to compress arbitrary analog data at very high sample rates as opposed to other general purpose compression algorithms?

Hi. I was wondering if there was any interest in extending the flac container format to support sample rates above the 655k current limit. Please note this is not for using ridiculously high sample rate sourced audio for some imaginary audible benefit. I've been involved in some experimentation with offline upsampling in software prior to delivery to an external DAC as a way to bypass the

...nd the result would still work with an existing decoder. But that would not work so well anymore for starting in the middle of a FLAC stream without having encountered a STREAMINFO metadata block -- dunno when that might happen. -olli (I am not a FLAC developer) On Tue, Jun 2, 2020 at 6:59 AM Con Kolivas <kernel at kolivas.org> wrote: > > Hi. > > I was wondering if there was any interest in extending the flac > container format to support sample rates above the 655k current limit. > Please note this is not for using ridiculously high sample rate > sourced audio for some...

...es would be multiples of the common 44.1/48 sample rates so I expect compression to be equally good with simple extrapolation to bigger equivalent sized windows.

...f multimedia things, especially recording music, mixing, etc. In order to use Linux as a digital audio workstation, there are a few things that one must do: use low-latency kernels, use pre-emption, use apps that run with real-time privileges, etc. For example, among audio Linux users, the CK (Con Kolivas) and LCK (Locosoft CK) patches are popular: http://members.optusnet.com.au/ckolivas/kernel/ http://www.plumlocosoft.com/kernel/ These patches provide O(1) scheduler, pre-emption, low latency, variable Hz, and other improvements that the audio community found not only useful, but actually require...
