A couple of requests for Crossover to add perceptual frequency scale (which admittedly, AIMP uses Mel scale for spectrum analyzer) like this:

And the feature to display multiple channels (including Mid/Side channels) in a single view to this component

And what about the constant-Q transform spectrum analyzer (which I think it deserved a separate component) that uses a sliding DFT? Because I doubt that foo_musical_spectrum will be updated to support 64-bit version of foobar2000 (which I have despite I don't have this component)

Wow! I keep a and pretty simple layout with all I need for all music I have and visualizations (including Loudness Peakmeter 1.0.0.0) and decided to add this today and it looks good and functions well. Foobar(32) 2.1 preview 5-24. Thanks Crossover!
There's free cheese in every trap.

The mel scale would be a nice option. I will keep that in mind. But that contradicts the concept I am working on at the moment cause the idea is to display the musical spectrum (notes) together with the frequency spectrum. I have attached a picture for this.
A function that displays different channels individually or simultaneously would also be a good option. For me personally, this function is not a high priority because I mostly listen to music that uses stereo channels.

Thank's, happy to hear that.

@Crossover please consider extending frequency measurement, for example from C0 (16Hz) to A11 (56kHz) (as in musical spectrum)

OK, I will try to integrate this in the next version.

For the Mel scale and musical notes thing, I know the musical notes are narrower at lower frequencies when viewed in a Mel scale as I played around with audioMotion-analyzer demos, especially with X axis labels

About constant-Q transform thing (unrelated to this current component, but it might be related to probably a new component although it fits better with musical notes thing), I already know directly calculating the CQT is slow even with Goertzel algorithm (about 5 FPS on 1/24th octave resolution with bandwidth offset of 300ms on my sketch), unless it is calculated using sliding DFT (which is better suited for real-time spectrum visualizations)

How about a spectrogram display in-addition to spectrum display like showcqt visualization?

BTW, I made the spectrum analyzer similar to Crossover's component and it features linear amplitude scale, which is useful for easily visualizing peaks

Crossover, are you working on the new component (perhaps a constant-Q transform spectrum analyzer) or something else?

Any idea: what about the colors of the specturm based on the album cover. not technical correct, but a nice design!

I'd like to migrate as well to something more modern (and supporting x64),

How can I upgrade to something that has the imo nice visuals of foo_wave_seekbar, foo_uie_vis_channel_spectrum, foo_uie_vis_peakmeter_spectrum and foo_vis_vumeter?

Any chance these components will run in a kinda sandbox within foobar x64?

In other words can this component be configured to look like good very old spectrum analyzer?

@Crossover, what about non-power of two FFT sizes like 4800 samples (100ms at 48kHz samplerate)?

As my Web Audio API visualizers starting with 2020 have non-power of two FFT size support, one year after being moved on from built-in FFT to custom FFT (which you can do the same trick with foobar2000 component development department)

Idea for this component (since tbh, neither foo_fft_analyzer, foo_cqt_analyzer, nor Wamoc as a whole exists): 1/3rd octave mode and rainbow gradient in which colors corresponds to musical notes like this:

The idea ist really great. But I think this demand should be realized by default or columns ui. A function of the ui system itself or an external component can extract the main colors out of the front picture and inform the client components by messages about the extracted colors.

No, the enhanced spectrum analyzer is an independent component. But I will add a draw mode for bars instead of a polygon, so that it can look like the well known spectrum analyzers.

Of course, it makes lots of sense for you to wait for an update on this component before working on the next thing (implementing the sliding DFT algorithm as foobar2000 visualizations, especially the CQT/VQT part in which no components have done it before)

No, nothing concrete is planned after the foo_enhanced_spectrum_analyzer enhancements, only holidays  :))  I have a new idea in mind but it has nothing to do with the sliding DFT algorithm or CQT/VQT.

So what's the idea? Perhaps linear/sqrt amplitude scale or even spectrogram view?

Thank you! 2.1 has been sorely missing a spectrum analyser and fab visualiser - this is great!

Just checked the page for a new visualizer called CoolEdit Nostalgia for another player MusicBee and I found out that this plugin has a feature to visualize FFT of separate channels, kinda like "dual-combined" channel layout setting on audioMotion-analyzer.

BTW, this MB plugin also have linear frequency scale option, which audioMotion-analyzer has (alongside Mel and Bark scales) and foo_enhanced_spectrum_analyzer doesn't (although I already requested the Mel scale for this foobar component).

Can't wait for this! I was hoping it would have the bars added. I prefer that look much more than the "smoothed" slope look.

Thanks for your awesome work! Adding the "bars" (shown above) will be awesome.
