Talking with an #LLM can drive people mad, like discussions with antique prophetic beasts. But why?
I look at #GenAI through the prism of ancient myths about composite gods and creatures like the #Chimera, the Moloch or Kṛṣṇa. The show articulates #vae and #modular generated sounds with a poetic conference on "AI-Chimeras"

I found a nice improvement to the Constant-Q Sliding DFT¹.

Using single precision calculation (32-bit float) generates some remanent noise because of the recursive nature of the algorithm: a running sum combined with complex rotations.

Replacing the complex multiply in eq. 3 for the twiddle factors (outer exponential) with the Martin Vicanek’s quadrature oscillator² helps a lot in the low frequencies. About 30 dB of improvement here, almost no extra CPU cost.

#LinuxAudio explorations - in my careful delving into #AirWindowsConsolidated I am finding that I really want a #Spectrogram to refer to so I can see the spectral changes that these different plugins bring to sound.

#ToneBoosters Spectrogram plugin works pretty well - once you set it up properly. May suggest to you that the first thing you do is to head to Settings in the upper right corner (not the lower left Settings) and scroll all the way down the list of options which are shown and enable GPU acceleration. When this is off on my PC it is virtually unusable. When on, it is smooth and easy to work with.

Thanks @linuxdaw for having a solution easy to hand!
