TDR Prism is a modern frequency analyzer with a focus on human audio perception. Easy to use and configurable, this audio plugin gives precise insight into the spectral properties of a signal. Among its flexible audio sourcing, decoding and visual configuration possibilities, Prism features a wide range of spectral weighting/tilting methods, peak/RMS smoothing options, including human auditory filters and real-time indication of auditory masking.
