Acon DeFilter

DeFilter is an efficient tool to even out tonal imbalances in a recording, reduce resonant peaks, dips in the frequency spectrum. Even severe issues such as comb filter effects, standing waves from untreated rooms can be addressed. DeFilter can match recordings to target profiles such as music speech, alternatively extract the overall timbre from the source – the large strokes – while evening out narrow peaks dips. The latter removes resonances, comb filter effects effectively while preserving the tonal character of the input signal. Recordings can also be equalized to match a reference recording. Great care has been taken to provide a user interface that is straightforward to use. Frequency dependent correction levels can be defined using custom curves, so that DeFilter can focus on problematic frequency ranges while leaving other frequency regions untouched. Realtime spectrum analyzers for both the input output signals visualize the effect on the frequency spectrum.
