Opus / Re: Opus decoding complexity
Last post by Klymins -
@Heliologue Thanks. Of course it's subjective, but it even does not sound better than MP3 for music to me. @saratoga Looks like you're wrong. I did the decoding speed test myself and MP3 was way faster than Opus.

Lossless / Other Codecs / Re: HALAC (High Availability Lossless Audio Compression)
Last post by Hakan Abbas -
The comment of everyone who comments is valuable to me. @mudlord , @Kraeved
As of now, HALAC is still in the development phase. The newest of other lossless codec except HALAC is close to 20 years of age. As I find time now, I try to establish the compression ratio/speed balance. I can see that there is a gap here.
When my improvements are over, it can be a codec that everyone can use. However, there is a lot of structural changes at the moment. And this is not very suitable for general use. However, 0.2.7 can now be encoded, decoded and listened to, albeit experimentally.

@Case
Thank you so much for foobar2000, Case. I have no desire to develop a new player. I just wanted to show that HALAC files can be listened to. So I prepared a very simple DLL.
  • I usually work as ANSI. Yes, Unicode support can also be added. I will have to make some change for this.
  • Decoded data in terms of convenience are returned as a single WAV. However, I can do this in the form of frames (up to 1 MB). However, in this case, the relevant Players should also use the data in pieces. I did not want to deal with it in the Player I have developed for now.
  • Since the maximum size of the WAV files was u32 bit, I didn't need more. This can be increased, no problem.
  • I need to add error controls, especially version control. It is true that I have ignored this stage a little.
  • I added the SSE2 version of DLL to Github. However, I have never needed 32 bit until now. If necessary, I can also compile 32 bit. But considering the whole structure, of course, there will be things I need to change. Therefore, the subject of 32 bit is less priority for me for now.

Audio Hardware / Re: audio device on Beelink u59 / AZW U59 (U3E1)
Last post by stanley.tweedle -
Hi there. My sincere apologies for never revisiting. I'll have to verify my contact settings for topic replies.

This problem still plagues me. Yes, @Octocontrabass , mine is the "Pro" model. I just pulled up the Amazon invoice from 2022, which still links to the product that i purchased. That's it, but I did upgrade to 32GB RAM.

I annotated a screencap to attempt demonstrating. This device isn't working again, so I tried a bluetooth speaker I have but it's not functioning either.

I've downloaded and installed the drivers from the Beelink website in the past (pretty sure it's that same file). Why it's listed for Windows 10, when the product ships with Windows 11, who knows! Got 'em again just now and will install.

But I did not realize there's a different set. I can't believe what a pain in the @$# this thing has been with the audio. Cracks like digital distortion. Like a bad cable or something. Turn the output way down, and the amp way up maybe it's a little better. That sucks anyway.

@Porcus that's some interesting and insightful news! I knew I'd come across the best information here. I'm always doing something else and forget to follow-up on the things that are "for me". Or, I got it working. Seems like I go through it every quarter year or so.

Sorry. I'm really excited to see all of the replies to little old me's post here. I feel like a jerk for letting it sit here.

I'll come back to report my findings if i'm allowed!
:)
 
Best regards.


Installing a software, FxSound -- much to my surprise, i assure you -- has fixed this problem in the past. That's some weird software. I don't understand what it does. It makes it seem like there's a new device, vs just being some kind of DSP. That's not where my genius lies. I've plugged guitars into rack-mount DSP's n stuff like that, been in recording studios and used really high-end gear. I know enough about it all to have a basic idea of what it probably is, but then I fail. And with this driver situation being needle and haystack (perhaps you recall if you checked on it at all). Its enough to drive me more nuts than I am.

The true solution lies in a new purchase. It's fine if I don't have to be irritated by that garbage audio device.

I'm all ears if anyone knows of something similar for under (or around) $500
(e.g. out of my current price range, but this seems nice for 2024? I might be afraid to even look inside. One of those peanut brittle cans gag. Open it up, and interfaces and wires and components just fly out all over the room... fun for the whole family! i hate bein' old.)
