Total 15 diverse music sound samples, including highly critical samples.
Hardware: Sony PSP-3000 + AKG K712.
Results (only traditional codecs, at around 134 kbps):
Results (including AI codec at 7.5kbps, it is not a bitrate-equalized comparison):
Conclusions & Observations:
MPEG-4 xHE-AAC (eXtended High-Efficiency AAC), encoded by exhale (Ecodis eXtended High-efficiency And Low-complexity Encoder), had very high fidelity at around 134kbps, with average score over 4.5.
Ogg Vorbis, encoded by aoyumi's aoTuV beta6.03(latest version as of 2024 May), also had very high fidelity at around 134kbps, with average score more than 4.4.
It's not clear which encoder, xHE-AAC or Ogg Vorbis, was better, from this test alone. The difference was small.
Both xHE-AAC and Ogg Vorbis at around 134kbps were better than the TSAC: Very Low Bitrate Audio Compression at 7.5kbps, at its maximum bitrate setting as of 2024-04-08 version. TSAC used 94.4% less disk space, and this test not meant to be a filesize-wise fair comparison.

Surely, IIR filter bank can be made wider (lower Q parameter as there is no FFT size parameter for this filter bank-based analysis) while having larger number of bands per-octave to get a smoother spectrum with improved time resolution or responsiveness on lower frequencies (as we can't have narrow bandwidth while having good time resolution on lower frequencies at the same time obviously), try it out yourself by tinkering with "Bandwidth" parameter on my own AudioWorklet-based filter bank spectrum analyzer project
BTW, what I meant by "low detail mode" (BTW the name is borrowed from an option in Geometry Dash that improves performance on lower end PCs) is that when enabled, it tries to avoid drawing more lines if the distance between two points in pixel coordinates in terms of X-axis is within subpixel level (much like foobar2000's built-in "Oscilloscope" visualization), which makes it look more like "Line/Area graph" mode in audioMotion-analyzer than " Spectrum analyzer and spectrogram using custom FFT" especially at higher FFT size like 32768

You need to change the base to a vertical splitter. Then you can right click that add multiple panels. Each one added to a vertical splitter is laid out top>bottom. If you want to insert left to right, add a horizontal splitter. Then you can right click that and add panels to it.

i have created a new user i have added jsript panel 3 but I have no idea how to the add more i right click jscript 3 in the uil layout and get change base
Please check input and output (compressed as FLAC, because it fits within the 30 MB of files per post limit for the forum). ABX them, and listen them carefully. Post the results when done!
During the first second the input sounds more metallic. The codec simplified the output. But I don't think this kind of thing is even meant to be transparent. Just a tech demo to squish things slowly into tiny space, modern day VQF.
