this is a server on Raspberry pi who allow a client to call via RAW socket to send a sound via a json
i use 4 simples soundcards, 4amp, 8 speaker and a RPI 4.
this project use RTaudio, json and AudioFile
to compile it do :
g++ -Wall -D__LINUX_ALSA__ -o multiaudio3 multispk.cpp spk.cpp engine.cpp Vecteur3d.cpp AudioFile.o RtAudio.o -lasound -lpthread -Wno-psabi
multispk.cpp is the main file
spk.cpp control the speaker
engine.cpp controle the process for 3D sound and the client ask
you can clone the git and do :
use to config.conf file to add sound (wav 44,100 16bit) like this :
audio=foo.wav;bar.wav; (many.wav) .....
each sound take respectivly an id foo.wav will be the 0 bar.wav the 1 etc ...
./multiaudio3
it start a server
to try it use putty in a RAW channel
for launch a sound tape [ispos,idbuffer,command,loop,[posx,posy,posz]]
ispos : if ispos = 255 the sound will be launch everywhere else use posx, posy, and posz as double.
idbuffer : the buffer of the sound.
command : P for play or S to stop.
loop : if loop is 0 the sound will loop.
[posx,posy,posz] : the postion of the sound
exemple :
[255,0,"P",1] //Play the sound
[255,0,"S",1] //Stop the sound
[0,0,"P",1,[1,1.4,1.2]] //Play the sound in a position define by [posx,posy,posz]
[255,0,"S",1] //Stop the sound again
