These cards do not have their ADC and DAC synchronised. Do common on-board or PCI sound card lock to some incoming signal? Yes, there is a crystal oscillator and a PLL or divider to

Hi all, The conclusion of the discussion is that most sound cards indeed have different capture and playing frequencies for the unknown reasons. But we all know the adaptive filter of the AEC relies on the synchronization of the far-end and near-end sampling rates. Then Has anybody tried to use speex AEC in Windows system? How do you solve this problem? (I have tested speex AEC. In most

AFAICT our current version does not correspond to any version in the Linux history. This commit resynchronised to the state in Linux commit 598bae70c2a8e35c8d39b610cca2b32afcf047af. Differences from upstream: find_cpio_data is __init, printk instead of pr_*. This appears to fix Debian bug #785187. "Appears" because my test box happens to be AMD and the issue is that the (valid) cpio

...ported by the operating system. > In addition to what everyone else has said ... The terrestrial radio clocks are actually not that accurate. They are not designed for keeping things like a system clock "correct". Commercial solutions only keep to within about +/- 0.5s per day, with resynchronisation happening about once a day. The GPS time system is also notoriously very precisely wrong. The time was set when the first satellite was sent up and has never been corrected since - so hasn't taken account of leap seconds or relativistic effects. All that matters for GPS is that the time on eac...

...know if the problem is xen or drbd related ? Unfornately I have no traces on the xen node. I set "ecbo 60 > /proc/sys/kernel/panic", but it doesn''t seem to be a kernel panic, but a "xen" panic.

I have a (CentOS4.5) cluster in which the servers mount a GFS partition which is an LVM2 logical volume created as a mirror of two iSCSI- connected drives (with a third for the log). The LV was created using a command along the lines of: lvcreate -m 1 ... /dev/sdb /dev/sdc /dev/sdd where sd[bc] are the mirrored (iSCSI) PVs in the VG and sdd is the log. I have this working and can write data

One of our STEM interns recently observed that there are inexpensive clocks that sync via radio to standard time services.? This begged a question about why every computer would not have a radio module to receive time.? Our senior staff did not have a good answer or if time from such a radio module would be supported by the operating system. When I was a student, such questions would have earned

Windoze in da NUT house! Codebase of the NUT for Windows branch was merged to main codebase, not in the least to avoid bit-rot and need for resynchronisation with merge conflicts that regularly arose as the two branches "just co-existed". More community work is needed to complete some drivers' functionality and MSI package delivery, but for many use-cases it may already "just work" using tarballs from AppVeyor CI. Happy back-to-...

Then why ONE sound card have different capture and playback rate? It must be ONE single physical clock generator which is used by both ADC and DAC in the sound card, isn't it? If you are a hardware engineer. Will you design two different physical clock for ADC and DAC seperately? What on earth causes this problem? Who knows its intrinsic real reason? Isn't there any other solutions? For

"Good news, everyone!" With CI builds of the branch now regularly passing on both the multiplatform FOSS NUT CI farm (including linux+mingw cross-builds), and CircleCI with MacOS, and newly on AppVeyor with Windows+MSYS2 (including integration tests with live upsd and some dummy-ups instances), after ironing a few wrinkles I intend to PR and merge it into the main NUT codebase soon,

Back from vacations, and before I dive into real-life work, I went over some ideas and notes from the NUT for Windows effort. Now they should be tracked at https://github.com/orgs/networkupstools/projects/2/views/1 and community help is welcome :) I probably forgot or missed some caveats - so feel free to post issues for this project if you think of some more...

...o small overhead. o simplicity to be fast. o simple concatenation mechanism. All of these design considerations have been taken into consideration for Ogg. Ogg supports framing and interleaving of logical bitstreams, seeking landmarks, detection of corruption, and stream resynchronisation after a parsing error with no more than approximately 1-2% overhead. It is a generic framework to perform encapsulation of time-continuous bitstreams. It does not know any specifics about the codec data that it encapsulates and is thus independent of any media codec. <p><p&g...
