MP3 - General / Re: Resurrecting/Preserving the Helix MP3 encoder
Last post by maikmerten -Examples:
This generates 44.1 kHz stereo encodings with roughly ~96 kbps (-V0 usually targets ~112 kbps) with a lowpass of 16 kHz:
Code: [Select]
hmp3 -F16000 -V0 -T-20 input.wav output.mp3
This allows encoding high-frequency content (> 16 kHz) even at low VBR bitrates such as ~128kbps:
Code: [Select]
hmp3 -V80 -T-40 -HF2 input.wav output.mp3
This increases the VBR quality target beyond what's usually possible (~310 kbps VBR instead of ~260 kbps VBR):
Code: [Select]
hmp3 -V150 -T50 -HF2 input.wav output.mp3
So that's a parameter for fun experiments.

Last post by Busty -There's just one thing I'd wish for to make it perfect for my needs, which would be group by artists and albums.
I got about 200.000 audio files in my library and it really takes a while to scroll all the way down to the bottom. In fb2k itself I group them by artist and then by album and that way I can manage that library. I haven't found a way yet to pass something like group by artists over to this remote interface. I might be stuck to listen to AC/DC and will never go down to ZZ Top that way, it just takes too long:-)
Is there a way to achieve this? Right now it's like mrjayviper says, it shows one huge playlist (or the playlist I chose to play from the foobar2000 application)

Last post by maikmerten -Oh, that's perfectly fine. Thank you for asking.
Let me know if you need higher resolution images.
Some more details if required:
Pink noise, stereo, 16 bits, 44.1 kHz, -10 dB, uniform distribution
Used spectrum analyzer is Spek.
Thank you, I uploaded the images with attribution and the details you provided to the Wiki and embedded them in the Helix MP3 Encoder page.
As for the various reports of the different Win32/Win64 compiles behaving vastly differently, I currently don't have a good hypothesis on what's going on there. I wouldn't, e.g., expect builds with different optimizations (e.g., PGO or no PGO) to make the difference between a machine getting unresponsive or working properly. Also, doing static builds (-static linker flag) only means that the required system libraries are included in the build - I don't quite see how this should have a meaningful performance impact (unless the system libraries are somehow misbehaving).
So I guess it might be a good idea to somehow collect data on the various build options and find a Windows build solution that works reliably.
Other than that, I'm pleased that apparently some people are getting results that indicate it's now possible to encode hours of audio in mere seconds. I remember working on machines where this used to be the other way around...

Last post by pqyt -Hi @pqytDirect2D has no direct way AFAIK to impact the refresh rate. It's tied to the DirectX swap chain and the swap chain, by default, is tied to the monitor refresh rate. The DXGI layer of DirectX does provide an API to interact with the swap chain. I've dabbled with it before when experimenting with background transparency. Re-introducing DXGI is on the To Do list.
thank you for your awesome plugin. I have a newbie question, I have installed v0.7.6.2 (Foobar2000 v2.1.4 32bit), if I set the Frame Counter on and at the same time I try to change the Refresh Rate Limit to 100Hz or 200Hz the counter always shows about 60 fps. My monitor refresh rate is 144Hz (correctly set in Windows display options). Is the bar animation always capped to about 60 fps maximum ? Thank you in advance
Most DirectX example code is focused on gaming and does not care how the refresh impacts other processes and just uses a high frequency system counter but a fb2k component has to co-exist on the desktop with other applications.
So, to answer your question: my code is not limited to 60Hz. It goes where the timer takes it. But I have to use other API's to make it listen to higher refresh rates. Hard to test when my own set-up is limited to 60Hz...

Last post by Case -But there is something more going on. My timer resolution was 1.0 ms because of background processes and I had a nice 100 fps rendering from this component. But once I shut down all background programs that increased the resolution so that the system returned to default 15.6 ms timer, Spectrum Analyzer got limited to ~64 fps here too.
And now even if I force timer to 0.5 ms accuracy I can't surpass the 60-something limit. My monitor is running at 144 Hz too.
Hopefully pgyt can figure out what is limiting this thing.
