Applies a two-pole all-pass filter.
F_aloop
 
Loops audio samples.
F_anoisesrc
 
Generates a noise audio signal.
F_aperms
 
Set permissions for the output audio frame.
F_aphaser
 
Adds a phasing effect to the audio.
F_aphaseshift
 
Apply phase shifting to input audio.
F_arealtime

Cut subwoofer frequencies.
F_asupercut
 
Cut super frequencies.
F_asuperpass
 
Apply high order Butterworth band-pass filter.
F_asuperstop
 
Apply high order Butterworth band-stop filter.
F_atempo
 
Adjusts audio tempo so that when you speed up audio, it will adjust the pitch accordingly to make audio sounds more normal, but faster without being badly distorted. Its behavior is similar to what can be seen when you watch a youtube video, click the gear icon, and select a speed greater or less than 1.
F_atrim

F_bandpass
 
Applies a two-pole Butterworth band-pass filter.
F_bandreject
 
Applies a two-pole Butterworth band-reject filter.
F_bass
 
Boosts or cuts lower frequencies.
F_biquad
 
Applies a biquad IIR filter with the given coefficents.
F_chorus
 
Adds a chorus effect to the audio.
F_compand
 
Compresses or expands audio dynamic range.
F_compensationdelay
 
audio compensation delay line.
F_crossfeed
 
Apply headphone crossfeed which blends the left and right channels of a stereo audio recording. It is mainly used to reduce extreme stereo separation of low frequencies in order to produce more speaker like sound.
F_crystalizer
 
Simple Expand Audio Dynamic Range filter.
F_dcshift
 
Applies a DC shift to the audio.
F_drmeter
 
Measure audio dynamic range where setting window length in seconds is used to split audio into segments of equal length.
F_dyaudnorm
 
Dynamic Audio Normalizer. When using this plugin, be sure to attach effect to all audio tracks by dragging the plugin to the 1st audio track and then right mouse clicking all subsequent audio tracks which brings up an menu. Highlight the effect shown in the middle section and click OK.
F_earwax
 
Widens the stereo image. When using this plugin, be sure to attach effect to all audio tracks by dragging the plugin to the 1st audio track and then right mouse clicking all subsequent audio tracks which brings up an menu. Highlight the effect shown in the middle section and click OK.
F_equalizer
 
Applies two-pole peaking equalization (EQ) filter.
F_extrastereo
 
Increases difference between stereo audio channels. When using this plugin, be sure to attach effect to all audio tracks by dragging the plugin to the 1st audio track and then right mouse clicking all subsequent audio tracks which brings up an menu. Highlight the effect shown in the middle section and click OK.
F_flanger
 
Applies a flanging effect to the audio.
F_haas
 
Apply Haas Stereo Enhancer for a more natural sounding pan effect or more clarity in the center of the mix. With this filter applied to mono signals it gives some directionality and stretches its stereo image.
F_highpass
 
Applies a high-pass filer with dB point frequency.
F_hilbert
 
Generate a Hilbert transform FIR coefficients.
F_loudnorm
 
EBU R128 loudness normalization.
F_lowpass
 
Applies a low-pass filter with dB point frequency.
F_mcompand
 
Multiband Compress or expand audiodynamic range. The input audio is divided into bands which is like the crossover of a loudspeaker, resulting in flat frequency response when absent compander action.
F_pan
 
Remix channels with coefficients (panning).
F_silenceremove
 
Removes silence.
F_sine
 
Generate sine wave audio signal.
F_stereotools
 
Applies various stereo tools. When using this plugin, be sure to attach effect to all audio tracks by dragging the plugin to the 1st audio track and then right mouse clicking all subsequent audio tracks which brings up an menu. Highlight the effect shown in the middle section and click OK.
F_stereowiden
 
Applies stereo widening effect. When using this plugin, be sure to attach effect to all audio tracks by dragging the plugin to the 1st audio track and then right mouse clicking all subsequent audio tracks which brings up an menu. Highlight the effect shown in the middle section and click OK.
