Measuring the two LFOs on The Who's 'Won't Get Fooled Again' — gate/mute rate and VCF sweep rate from the isolated organ stem

Measuring the two LFOs on "Won't Get Fooled Again"

Analysis of the isolated organ stem from The Who's Won't Get Fooled Again (8:26, 44.1 kHz), recovering the rates of the two modulators applied to the Lowrey organ:

  1. the square-wave VCA gate — the "mute" chop
  2. the sine/triangle LFO on the VCF cutoff — the slow filter sweep

analyze_lfo.py is self-contained and reproduces every number below:

La imagen corporativa de TVN (2001): análisis del ident «Chile, territorio y soberanía» y de su making of — motion control, Image G y la grúa Bulldog

La imagen corporativa de TVN (2001): análisis del ident y de su making of

Análisis cuadro a cuadro del inicio de transmisiones de Televisión Nacional de Chile del período 2001–2004 y de su registro de rodaje, «Making of imagen corporativa TVN 2001».

Es, probablemente, la pieza de continuidad televisiva más ambiciosa producida en Chile: un logotipo construido como estructura física de siete metros, trasladado a lugares apartados del país y filmado con una grúa de motion control recién premiada con un Óscar técnico.
