[ back to the void ]

These are the five pages exactly as fradan renders them. The take is friday night late performance - 11, one of the void analogue live sets, two minutes of an AAC stream at 48 kHz.

The source is lossy, from an m4a file. The method looks for a brickwall and a stopband, and AAC at this rate leaves the band open all the way to the top, so there is nothing of that shape to find. Page 2 reads a synthesised chain rather than a captured one. The noise floor tracks level at 1.01 dB/dB and there is no modulation peak above 20 Hz. Page 3 is a clock, 127.9 BPM with 0.2 BPM of wander over 1188 onsets. Page 4 is the mastering, -13.3 LUFS gated over 5.1 LU of range, with one clipped run at +0.1 dBTP. Page 5 is the new one, and it is where the existence of the codec finally becomes obvious. It reports 0.23 s of reverberation and +12.8 dB clarity at only 76 percent confidence, because the decays it fitted had already been through an encoder.

PAGE 1:: CODEC ARTIFACTS
Spectrum over time with the per-frame lowpass cutoff traced over it, the artifact distribution showing only what was removed, localised per-second evidence, cutoff distribution, holes by band and the mean shelf profile.
PAGE 2:: SYNTHESIS VS CAPTURE
Stereo coherence and width over frequency across five time slices, noise floor against level, modulation spectrum by band, and top-octave activity against the whole band.
PAGE 3:: TIMING AND TRANSIENTS
Local tempo over time, every onset's distance from a fitted sixteenth-note grid, spectral seams, the distribution of 10 to 90 percent attack rise times, and the average attack shape aligned at its peak.
PAGE 4:: LEVEL, DYNAMICS AND BALANCE
Momentary and short-term LUFS against the gated integrated value, the short-term loudness histogram with its p10 to p95 range, peak to short-term crest, third-octave long-term average spectrum, whitened resonances, and a goniometer with inter-channel correlation.
PAGE 5:: ROOM ACOUSTICS AND BACKGROUND
Reverberation and early decay time per octave band with the spread across fitted decays, the backward-integrated decay curve, modulation depth against rate behind an STI figure, the band-summed envelope with the free decays that were fitted, background level per octave band, and inter-channel correlation falling with frequency.
