Introduction

Spectacle is a real-time spectral analyzer using the short-time Fourier transform, available as LV2 audio plugin and JACK client.

  • display the spectrum on logarithmic musical scale
  • control the parameters of the analysis that affect latency and precision
  • have zoom functionality and smooth interpolation
  • identify the value under cursor and the peaks

Controls

  • resolution: number of frequency points evaluated by STFT, greater CPU load in high values
  • step: linked to the rate of STFT updates, faster when low but also more CPU consuming
  • attack time: reaction delay to rapid increases of amplitude
  • release time: reaction delay to rapid decreases of amplitude
