DeFilter is a powerful tool that can effectively address tonal imbalances in recordings, as well as reduce resonant peaks and dips in the frequency spectrum. It is capable of handling even severe issues such as comb filter effects or standing waves resulting from untreated rooms. This software allows you to match your recordings to target profiles like music or speech, or extract the overall timbre from the source while simultaneously evening out narrow peaks and dips. This approach effectively removes resonances and comb filter effects while preserving the tonal character of the original signal. Additionally, DeFilter can equalize your recordings to match a reference recording.

The user interface has been designed to be intuitive and easy to use. You can customize frequency-dependent correction levels with custom curves, enabling you to address specific frequency ranges while leaving others untouched. Realtime spectrum analyzers for both input and output signals provide a visual representation of the effect on the frequency spectrum, making it easy to monitor and adjust the changes in real-time.

Key Features:

• Automatically estimates correction filter that evens out the frequency spectrum
• Removes resonances and comb filter effects
• Predefined target profiles include music, speech and an automatic mode that extracts timbre from the input signal
• Correction filters can be saved and used as a reference for matched equalization
• Adjustable length of the correction filter from 1 to 20 milliseconds
• Frequency spectrum representation of the of the following signals:
• Correction filter
• Input signal
• Output signal
• Frequency emphasis filter for the the level of correction
