Create an accumulator (type 1) element
#include <audio_driver.h>
ado_mixer_delement_t *ado_mixer_element_accu1 (
ado_mixer_t *mixer,
char *name,
int32_t attenuation );
- mixer
- A pointer to the ado_mixer_t structure that specifies the
mixer to create the element in.
This structure was created by
ado_mixer_create().
- name
- The name of the element.
Elements are referred to by name, so be careful; for some standard names, see
<asound.h>.
- attenuation
- The amount of attenuation the element contributes to the stream passing
through it; usually 0 dB.
The ado_mixer_element_accu1() convenience function
automates the creation of an accumulator (type 1) element.
An accumulator of type 1 mixes together
multiple inputs into a single output.
A pointer to the newly allocated accumulator (type 1) element.
