Hi Sebastian,
I assume that you want to play both the sounds simultaneously when the condition meets ‘[1 3]’.
The audios may sound distorted because there is data drop when the audio files are loaded and played, the file size can also influence data drop. You will have to make some compromises with the device properties. You can refer to this sample code to play two sounds simultaneously –
hmfr1 = dsp.AudioFileReader(filename1);
hmfr2 = dsp.AudioFileReader(filename2);
hap = dsp.AudioPlayer('DeviceName','Speakers (SoundMAX Integrated Digital Audio)',...
'SampleRate',hmfr1.SampleRate,'QueueDuration',3);
while ~isDone(hmfr2)
audio1 = step(hmfr1);
step(hap, audio1);
audio2 = step(hmfr2);
step(hap,audio2);
end
For more information refer to the link attached below.
Hope it helps!
