FreeFilter stands for a linear phase real-time 1/3-Octave Equalizer tool developed by the well-known audio research company Spectral Design. With up to 30 bands it offers fine adjustment of all sensitive frequency regions, and the possibility of switching from logarithmic to linear mode enables a wide range of applications.

The finesse lies in the accurate analyzing ability of FreeFilter.For example, take a piece of audio which you feel is well mixed.Let FreeFilter learn the frequency spectrum, then adapt it to the song you’re working on. That powerful function makes FreeFilter ideal for producing compilation CDs with different mixed titles. A morph function gives you the freedom to morph between the source and processed file at any time - dynamically and in real time.
For example, finding the right sound of different mixes is done within minutes. The huge display shows exact information about the spectral frequency shape of the learned audio signals and their differences.
