3rd Party Plugins - (fb2k) / Re: foo_enhanced_spectrum_analyzer
Last post by TF3RDL -
I'd be patient about optimizations on this component to get 60FPS on fullscreen mode and lower CPU usage, and my proposed analog-style analyzer/IIR filter bank mode (right now, there is no analog-style spectrum analyzer component for fb2k, so I used foo_dsp_vst3 to visualize audio using Voxengo AnSpec) for frequency bands mode can benefit from usage of SIMD instructions (for the case of AVX instruction usage, a fallback to SSE4.2 and SSE2 for stability) and multithreading can benefit the performance of calculating two or more spectrum in this case of multiple graphs (which foo_vis_spectrum_analyzer going to have) and/or overlayed channel spectrum displays right?

Also, add a Gaussian window function (with window parameter of 2.4 to match foobar2000's built-in spectrum visualization method) in-addition to fixing the regression of window function settings not actually applying different windowing functions as well as adding an option to show either the DC label (only shown when used with any frequency scale other than logarithmic), Nyquist frequency marker, or both

BTW, I think the @Crossover's Enhanced Spectrum analyzer (foo_enhanced_spectrum_analyzer, this component) and @pqyt's Spectrum Analyzer (foo_vis_spectrum_analyzer) serves different purposes even though both of them are spectrum analyzers; the former is for something like professional audio analysis and the latter is for eye candy, but still serves more useful purposes than Winamp's Classic Spectrum Analyzer plugin

Listening Tests / Re: Great killer sample, easy to ABX on most codecs
Last post by Kraeved -
@shadowking, I tried the settings you suggested for WavPack, up to -b4.55x5s.5, and I still hear that hiss. Aggrrrhh! Since this sample sounds more like regular music than a proof of concept, I have a panic at the thought that other music could be compressed in such a low-quality way. So I suspend the use of the hybrid WavPack and hope that @bryant will be able to fix it.

FLAC / Re: FLAC v1.4.x Performance Tests
Last post by Kraeved -
Those of you who have been aware of the development of FLAC all these years, please tell me if there are any significant changes between versions 1.3.4 and 1.4.3? I ask because the amazing FSLAC lossy encoder by @C.R.Helmrich that works like LossyWAV is still based on version 1.3.4, and I'm worried.

Support - (fb2k) / Re: foobar2000 Latest preview version
Last post by PaperBoat -
It is possible that the new CPU usage optimizations don't play nicely with very low output buffer sizes combined with CPU-heavy DSP. The next update will address this.

For now, please try increasing output buffer size in Preferences / Playback / Output.


Temporarily I shifted to the stable version and I always set device buffer at 50ms. My DSPs are CPU heavy (Fabfilter Pro MB and Pro L2).
