TBProAudio has released DSEQ 3.5, a dynamic spectral equalizer. DSEQ removes digital harshness on the fly thanks to self-adjusting frequency bands.
DSEQ offers now adaptive slope, adaptive threshold and natural phase filter.

DSEQ can be used in all mix and master situations:
  • de-essing vocals
  • taming resonances in e.g. drum, guitar, vocal recordings
  • removing digital harshness
  • balancing the mix
  • de-masking frequency regions
  • support of pink noise mixing/mastering

The natural phase filter reduces pre-ring while taming resonances or removing digital harshness.
The adaptive slope and threshold continously calculates the optimal slope and threshold values based on the input signal. Combined with the loundess matching it instantly improves resonances or digital harshness with no or small user interaction.
