Spectral Analysis by MeldaProduction

Free Product


Spectral analyzer and sonogram measuring average, infinite average, temporary maximum and infinite maximum. Smoothing spreads energy between ranges of frequencies for perfect optical recognition. Prefiltering providing for example equal loudness contours, which therefore implements a simplified human hearing. Super-resolution improves resolution in low frequencies, but keeps the speed of higher frequencies. Standard FFT analyzers have poor resolution in low frequencies due to logarithmical scale of human auditory system.

  • Super-resolution fixes this problem and provides high resolution in both high and low frequencies. 
  • Deharmonization reduces harmonics leaving only fundamentals, which is great for identifying relevant frequencies. 
  • Magnitude normalization for better optical comparison. Freeze mode. 
  • Copy/paste to clipboard to compare in another analyzer window. FFT sizes from 1024 to 16384. 
  • Overlapping and adjustable windows for maximal precision. 
  • Global preset management - using a title button you can save your settings, which are shared on the computer, so you can easily access them in another songs.

System Requirements


  • Windows Vista / 7 / 8 / 10 (32-bit or 64-bit)
  • VST / VST3 / AAX compatible host (32-bit or 64-bit)
  • Intel/AMD processor with SSE2 support

Always use 32-bit plugins in 32-bit hosts, or 64-bit plugins in 64-bit hosts!
64-bit plugins can't work in 32-bit hosts even if the operating system is 64-bit. Do NOT use 32-bit plugins in 64-bit hosts. They would have to be bridged and can become slow and unstable.
Mac OS X

  • Mac OS X 10.9 and newer (64-bit only)
  • VST / VST3 / AU / AAX compatible host (64-bit only)
  • Intel/AMD processor with SSE2 support or Apple Silicon processor

Note: Please check your product PDF documentation for more information and installation instructions.
