TBProAudio updates DSEQ to V3.5, a dynamic spectral equalizer for Windows and Mac OS X
by TBProAudio
15th August 2021
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.
