  • Visual spectral editing catches problems EQ alone can't fix
  • AI source separation for isolating stems or noise
  • Shows instantly whether a lossless-looking file was upconverted from a lossy source
  • Uses FFmpeg for decoding, so it opens the formats FFmpeg opens
  • Paid software from Steinberg's professional lineup
  • Steeper learning curve than a simple EQ or noise gate
  • Development is quiet: the last release, 0.8.5, is from January 2023
