with_fx :bpf
Combines low pass and high pass filters to only allow a ‘band’ of frequencies through. If the band is very narrow (a low res value like 0.0001) then the BPF will reduce the original sound, almost down to a single frequency (controlled by the centre opt).
With higher values for res we can simulate other filters e.g. telephone lines, by cutting off low and high frequencies.
Use FX :band_eq with a negative db for the opposite effect - to attenuate a given band of frequencies.
Introduced in v2.3
| amp: |
The amplitude of the sound. Typically a value between 0 and 1. Higher amplitudes may be used, but won’t make the sound louder, they will just reduce the quality of all the sounds currently being played (due to compression.)
Default: 1
|
| mix: |
The amount (percentage) of FX present in the resulting sound represented as a value between 0 and 1. For example, a mix of 0 means that only the original sound is heard, a mix of 1 means that only the FX is heard (typically the default) and a mix of 0.5 means that half the original and half of the FX is heard.
Default: 1
|
| pre_mix: |
The amount (percentage) of the original signal that is fed into the internal FX system as a value between 0 and 1. With a pre_mix: of 0 the FX is completely bypassed unlike a mix: of 0 where the internal FX is still being fed the original signal but the output of the FX is ignored. The difference between the two is subtle but important and is evident when the FX has a residual component such as echo or reverb. When switching mix: from 0 to 1, the residual component of the FX’s output from previous audio is present in the output signal. With pre_mix: there is no residual component of the previous audio in the output signal.
Default: 1
|
| pre_amp: |
Amplification applied to the input signal immediately before it is passed to the FX.
Default: 1
|
| centre: |
Centre frequency for the filter as a MIDI note.
Default: 100
|
| res: |
Filter resonance as a value between 0 and 1. Large amounts of resonance (a res: near 1) can create a whistling sound around the cutoff frequency. Smaller values produce less resonance.
Default: 0.6
