Beautiful-Sounding Calculations

The Spectral Repair Tool (SRT) option for soundBlade allows visual localization, identification and very precise removal of unwanted audio events without affecting the audio material you want to keep. The removed sound is replaced by a signal re-synthesized from the surrounding material.

SRT for soundBlade provides precise definition of the impairment in both the time and frequency domains. Unlike other superficially similar tools, SRT for soundBlade does its work in the linear-phase domain, so repairs are exceptionally clean and free of artifacts, even with very high noise recordings.

Praise for Spectral Repair Tool


SRT Standard Feautures:

  • Flawless operation with up to 384 kHz sampling rate
  • Enormous time savings when repairing critical live recordings
  • Extraordinary sonic results compared to any other cleaning method due to its selective spectral treatment
  • Processing performed in the linear-phase domain, preventing coloration & artifacting present in other spectral repair tools
  • Precise resizable and zoomable spectrogram with always visible metrics

Transparent Spectral Repair

    Spectral Repair Tool For soundBlade does not make deep gaps in your sound track when eradicating a disturbing sound event. Rather, it's an exactly tailored hole in the spectral representation of the processed signal that can be removed and replaced. The interpolation may even be restricted to certain gain ranges within the selected area, which is very useful if only a certain part of the signal needs to be treated (e.g. one specific harmonic). The Spectral Repair Tool For soundBlade window is fully re-sizable for increased accuracy and optimal compatibility with all screen resolutions.
