That's awfully close. Is a 0.3% error an acceptable compromise? (That's less than 4 minutes per day.)

I got lucky with that one. Even the 24k is acceptable. It's a roughly 0.7% error rate. I guess that would be ok.
But the 48k [46875], for example, has a very annoying chipmunk quality to it.

Opus / Help with sample rate issue

Last post by pauleffect90 - Today at 22:24

Hi guys. I'm working on an embedded project that includes an audio capture module.

For various reasons that may be tied to Murphys laws and my inherent bad luck, I can't use any of the *sweet spot* clocks for driving my audio peripheral. Long story short, I can't get a clean 16k, 24k or 48k sample rate in the MCU power mode I'm targeting.
I can get pretty darn close, but not quite there. The best values I can get are in the following table.

Desired frequency	Closest Inferior	Closest Superior
16000	15957	16666
24000	23809	24193
48000	46875	48387

I'd like to compress the audio samples using Opus. What do you guys suggest?

Seeing as I'm pretty close to the standard Opus sample rates, can I get away with doubling a few samples here and there? Or should I go for the next higher sample rate and maybe throw out a few samples?
Because power consumption is a big part of the project, I wouldn't be all too happy about burning precious sleep time with a fully-blown resampling algorithm (on top of the one opus uses anyway, that is).

Opus / Re: Is there an advantage in using bigger frame sizes (40+) for offline use?

Last post by pauleffect90 - Today at 22:05

60ms frame sizes, CELT only, fixed point math, yields *slightly* faster encoding times. By faster I mean a couple ms per encoded second. But, seeing as a few ms can mean the difference between life and a hard fault in the embedded world, it's something.
The benchmarks I've done were on Cortex M (arm32) MCUs.

3rd Party Plugins - (fb2k) / Re: Playlist Organizer (aka foo_plorg) replacement on Jscript Panel 3

@etip Another minor thing:
At the moment the panel only paints the border for the ActivePlaylist when the cursor, effectively, goes into it.
What I mean is, if I'm ctrl-tabbing between playlists, it doesn't "know" that playlist is active until I click into the playlist.
Do you think there's a way to make it work as soon as the playlist is shown?

i'm sorry, didnt get it, what do you mean by "paints the border of the activePlaylist" ?

@antares
i'll work on your first 2 items (the first one has been bugging me as well), the third is when i'll review the whole font topic.

General - (fb2k) / Re: foobar2000 v2.0 bugs

Hello.

Latest foobar2000 v1.6.16 and foobar2000 v2.0 still can't output 32bit files properly. It playback ok, status bar shows that it is 32bit, but my DAC internal test shows that it is 24bit instead of 32bit. When i test the same files with JRiver Media Center, DAC screen shows it as 32bit.

I use ASIO Output 2.1.2 and my DAC is RME ADI-2 Pro FS. The testing files i use are special wav files for testing bit-perfect playback of RME ADI-2 Pro FS

Can someone else check if it is possible to output 32bit files properly?

I have to question why you sent a DM to me personally about this when really its not my concern. I find that exceptionally irritating.

Porcus has your answer, anyway.

Support - (fb2k) / Re: V2 beta 26 [x86] not listing DSD tracks

Last post by glong - Today at 20:29

just for clarity - in order to get FB v2 beta to 'properly' re-database the folders which it had imported from V1, it was necessary to delete the folder from the album list - then to apply - then to quit FB and then add it again after restarting.

...simply deleting it and 'apply' and then re add it, did not refresh the file listing.

And in summary - that gave me back listings for .dsf files - but not .iso

I'm on Beta 27 now and it seems like there is a regression - the popping and lingering audio from the previous track upon manually changing tracks is back even though I have "Fast DSP reset when cycling tracks manually" off.
