What DeFilter does
The plugin compares the input signal against a target profile and builds a correction filter that evens out tonal imbalances. Predefined target profiles include music and speech, and an automatic mode extracts the timbre from the input itself. Correction filters can be saved and reused as a reference for matched equalization, so one recording can be equalized to match another. Realtime spectrum analyzers show the input signal, the output signal and the correction filter. The developer also notes that DeFilter can remove resonances and comb filter effects while preserving the tonal character of the input, and the correction filter length is adjustable from 1 to 20 milliseconds.
Key features
- Automatic correction filter. The correction filter is estimated automatically from the input and evens out the frequency spectrum without manual curve drawing.
- Target profiles. Predefined target profiles for music and speech set the reference the input is corrected toward, and an automatic mode extracts the timbre from the input.
- Reference matching. Saved correction filters can be used as a reference, so a recording is equalized to match another recording.
- Custom frequency curves. Frequency-dependent correction levels can be defined with custom curves to focus on problematic frequencies.
- Filter length. The correction filter length is adjustable from 1 to 20 milliseconds.
- Realtime spectrum display. Spectrum analyzers show the input signal, the output signal and the correction filter together.
Compatibility
It requires macOS 10.9 or Windows 7 and 1 GB of RAM, with native support for Apple Silicon listed. Pro Tools is named by the developer as a host.
