typedef struct {
    float 
      fDryMix;
    float 
      fWetMix;
    float 
      fFeedback;
    float 
      fDelay;
    BOOL bStereo;
    int lChannel; 
} 
      BASS_BFX_ECHO4;

Members

fDryMix	Dry (unaffected) signal mix	[-2..+2]
fWetMix	Wet (affected) signal mix	[-2..+2]
fFeedback	Output signal to feed back into input	[-1..+1]
fDelay	Delay in seconds	[0<...n]
bStereo	Only allowed with even number of channels	TRUE/FALSE
lChannel	The affected channels using BASS_BFX_CHANxxx flags

Info
This is an echo effect that replays what you have played one or more times after a period of time. It's something like the echoes you might hear shouting against a canyon wall. For reverb effect enable feedback.

The fDryMix is the volume of input signal & the fWetMix is the volume of delayed signal. The fDelay is the delay time in sec. The fFeedback sets how much delay is feed back to the input (for repeating delays). If bStereo is enabled and a stream has an even number of channels then, each even channels will be echoed to each other.

Examples

	Dry	Wet	Feedback	Delay
Small Echo	0.999	0.999	0.0	0.20
Many Echoes	0.999	0.999	0.7	0.50
Reverse Echoes	0.999	0.999	-0.7	0.80
Robotic Voice	0.500	0.800	0.5	0.10
