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

Apologies, I'll try to explain. Let's say you have playlist tabs, and you switch to a different playlist. Perhaps you have music playing in Default, but you switch to Michèle Bokanowski.
The panel will put a box around the active playlist's name in the panel. But it doesn't do so until you've actually clicked into the playlist.

What I often do is use ctrl+tab to change the active playlist. I don't necessarily use the mouse. I would like the active playlist to be displayed in the panel right away, if possible.

If this doesn't make sense I'll attempt a screen recording

Big numbers and lossy compression is an interesting topic

Opus / Re: Help with sample rate issue

48387 is closer, but if you ever want to play back with tempo adjustment, it goes in the opposite direction of the 16, so you cannot just give them all 0.5 percent in the same direction.

(Dumb question ... are your numbers correct? 48387/2 matches the number above it in the table, but not so in the left column?)

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

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

fb2k doesn't by default do ISO images. If they are SACD, then you probably need that component?

Did you get it working with WavPack? It should.

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 - 2023-03-20 22:24:10

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 - 2023-03-20 22:05:57

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.

@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.
