General Audio / I developed new resampler for high quality.
Last post by SYH9999 -
Hello. Today, I developed new resampler for high quality so let me introduce it.
This resampler optimized for pure in music, not for only signal(Sine Wave, Pulse Wave etc,,,).
Also, This resampler has high-quality bit converter, You can choose 8-bit quantize, It realize more low-noise than other resampler.
I put convert example to here, Check it on your ears.

Here is example

01 - 32kHz/6Bit
02 - 32kHz/8Bit
03 - 32kHz/16Bit
04 - Reference

Scientific Discussion / Re: AudioWorklet-based filter bank spectrum analyzer
Last post by TF3RDL -
Planned features to add:
  • Infinite average spectrum (which is what one of many things I wanted to be added in version 2.x.x.x of @Crossover's foo_enhanced_spectrum_analyzer component for foobar2000) like this:
    X
    X
  • Bark scale labels and grid, which follows more closely to auditory perception (I already know that it is neither linear nor logarithmic) than standard octave interval found in typical graphic equalizer effects from media players like Winamp. Something like this:
    X
  • Listen to certain frequencies feature like in Voxengo SPAN, which alters the audio output to what filter bank output sound like but it won't affect the analyzer (BTW, this is not possible as foobar2000 component iirc, but it is definitely possible as a VST plugin). Requires a new separate AudioWorkletProcessor dedicated for that since the filter bank analyzer is actually calculated in main thread (much like "Visualize with VST" feature in foo_dsp_vst3 component)
  • Tooltips on hovering over the visualizer window, to show Hz, closest note to frequency, and what dB corresponds to cursor, similar to foo_musical_spectrum

Once I have been able to login into CodePen, I would also make the mockups for future foobar2000-related stuffs (especially visualization and DSP components, including new features and proposed changes for existing components like Enhanced Spectrum analyzer) more public (through CodePen projects, which serves as an interactive mockup as usual) in-addition to implementing these proposed features above

General - (fb2k) / Re: Any way to query foobar2000 via CLI and get structured data?
Last post by Coreda -
Hmm, foo_httpcontrol looks like it may do much of what I'm after (JSON responses to queries, controlling playback, playlist info).

Seems there's no documentation apart from looking at existing templates but will test (did find a useful Reddit post about GET queries though). Also am I missing something or is there no ability on the forum to search in a specific thread?

3rd Party Plugins - (fb2k) / Re: foo_dsp_effect
Last post by mudlord -
Thats the problem.

librubberband is under the GPL. Thats completely incompatible with licensing when doing components for FB2K. Thats why I had to remove it, since I got scared of legal threats. Hence why sticking with SoundTouch which is fairly licensed, even if it has subpar quality.

David Bryant's lib would be a nice alternative to SoundTouch, and DEATH already did a tempo DSP with it, and doing pitch with it is fairly trivial (add a resampler stage)
