aliases: [fx.secho~]

enhanced echo effect

available since version: 0.6

information

Note: difference between fx.echo~ and fx.delay~ is that echo passes original signal with delayed repeats, but fx.delay~ passes only delayed repeats.

arguments:

• DELAY echo time
  type: float
  units: ms
  

• FEEDBACK feedback coefficient
  type: float
  

methods:

• reset reset to initial state
  

properties:

• @delay Get/set echo time
  type: float
  units: ms
  range: 10..10000
  default: 500
  

• @feedback Get/set feedback coefficient
  type: float
  range: 0..0.99
  default: 0.3
  

• @filter Get/set if true - apply filter to feedback signal
  type: bool
  default: 0
  

• @f_lpf Get/set feedback low-pass filter cutoff frequency
  type: float
  units: Hz
  range: 20..20000
  default: 9000
  

• @f_hpf Get/set feedback high-pass filter cutoff frequency
  type: float
  units: Hz
  range: 20..20000
  default: 300
  

• @compress Get/set feedback compression factor. 0: means no compression, 1: limit feedback level.
  type: float
  range: 0..1
  default: 0.5
  

• @c_thresh Get/set feedback compression threshold level
  type: float
  units: db
  range: -60..0
  default: 0
  

• @c_attack Get/set feedback compression attack time
  type: float
  units: ms
  range: 0.1..100
  default: 10
  

• @c_release Get/set feedback compression release time
  type: float
  units: ms
  range: 1..500
  default: 50
  

• @smooth Get/set interpolation time on delay time change, that prevents click and transpose, if equal to 0 produces artifacts on delay change
  type: float
  units: ms
  range: 0..500
  default: 50
  

• @drywet Get/set proportion of mix between the original (dry) and 'effected' (wet) signals. 0 - dry signal, 1 - wet
  type: float
  range: 0..1
  default: 1
  

• @bypass Get/set bypass flag. If true: bypass 'effected' signal.
  type: bool
  default: 0
  

• @osc (initonly) Get/set OSC server name to listen
  type: symbol
  

• @id (initonly) Get/set OSC address id. If specified, bind all properties to /ID/fx_echo/PROP_NAME osc address, if empty bind to /fx_echo/PROP_NAME.
  type: symbol
  

• @active Get/set on/off dsp processing
  type: bool
  default: 1
  

inlets:

• input signal
  type: audio
• set delay time
  type: control

outlets:
