Aten-Audio-Engine

Aten is a Linux Pipewire Audio Engine

For build

sudo apt install libpipewire-0.3-dev

For run

Effects

Reverb:Freeverb Algorithm

Using:

LuaJIT implementation:

local ffi = require("ffi")
local aten= ffi.load("atenaudio")
ffi.cdef[[
   int set_volume(int volume);
   float get_volume();
   int set_channels(int channels);
   int get_channels();
   int set_samplerate(int samplerate);
   int get_samplerate();
   int set_loop(int enabled);
   int get_loop();
   int stop_loop();
   int stop_sound();
   int stop_engine();
   int reverb(float roomsize,float damp,float wet,float dry,float width);
   int playsound(const char *format,const char *name);
   int ateninit();

Run

gcc aten.c atenimp.c eng/eng_pipewire.c eng/wav.c eng/mp3.c eng/effects/reverb/reverb.c -o aten -lpthread $(pkg-config --cflags --libs libpipewire-0.3) -lm -Ieng

Using Effects

Reverb:

Argument 0:Roomsize(Float)
Argument 1:Damp(Float)
Argument 2:Wet(Float)
Argument 3:Dry(Float)
Argument 4:Width(Float)

reverb(0.6,0.3,0.35,0.6,1.0);

Others:

Initing Reverb

reverb_init();

Set/Getting Reverb

Argument 0:Reverb(Integer(1/0))
NOTE:This function is not directly open Reverb. This function is setting engine's data struct int reverb variable
NOTE:If you do not call reverb_init() after using this function, the program will crash.

set_reverb(1);
get_reverb();

Setting Roomsize

Argument 0:Roomsize(Float)

reverb_set_roomsize(0.6f);

Setting Damp

Argument 0:Damp(Float)

reverb_set_damp(0.3f);

Setting Dry

Argument 0:Dry(Float)

reverb_set_dry(0.35f);

Setting Width

Argument 0:Width(Float)

reverb_set_width(0.6f);

Using Functions
