DeFilter is an efficient tool to even out tonal imbalances in a mix or reduce resonant peaks or dips in the frequency spectrum. Even severe issues such as comb filter effects or standing waves from untreated rooms can be addressed. DeFilter can match recordings to target profiles such as music or speech, or alternatively extract the overall timbre from the source – the large strokes – while evening out narrow peaks and dips. The latter removes resonances and 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 and output signals visualize the effect on the frequency spectrum. Use Cases Fix issues in a mix prior to masteringReduce resonances caused by untreated room acousticsMatched equalization (automatic equalization based on a reference signal)Improve clarity and intelligibility of speechInstant fix for nasty comb filter effects Acon Digital DeFilter is available for both Windows (PC) and OS X (Macintosh).
