FreqTweak is a tool for FFT-based realtime audio spectral manipulation and display.
It provides several algorithms for processing audio data in the frequency domain and a highly interactive GUI to manipulate the associated filters for each.
It also provides high-resolution spectral displays in the form of scrolling-raster spectrograms and energy vs frequency plots displaying both pre- and post-processed spectra.
