sdlAudioPlayer

simple interface for playing sndfile files from disk

local sndf = require"LuaJIT-libsndfile"
local AudioPlayer = require"sdlAudioPlayer"
--copy specs from file
local info = sndf.get_info(filename)
local audioplayer,err = AudioPlayer({
    --device = device_name, --nil as device
    freq = info.samplerate, 
    format = sdl.AUDIO_S16SYS,
    channels = info.channels, 
    samples = 1024})
--insert several files
for i=1,10 do
    --filename, level, timeoffset
    audioplayer:insert(filename,(11-i)*0.1,i*0.6)
end
--show them
for node in audioplayer:nodes() do
    print("node",node.sf)
end
--play them 7 secs
audioplayer:start()
sdl.Delay(7000);
--close
audioplayer:close()
