when i use ifft() to process and get a frame of audio data but forget to real() the results, it sounds weired.
so i wonder what happened when AudioDeviceWriter play with a complex inputdata?
i try it with a 1kHz pure tone and then plus it with a very little imag part，when played independently(commented the other)，these two sound very different. but when i play the two in sequence with a pause(3)，when the complex one first and real one latter,they sound the same(weired).
furthermore. when i change the order, put the real one first and the complex one latter, an error occured.

i’ll be glad to get an answer to the question ,thank you!
here is the code,you can change the order of adw(playbuff2) and adw(playbuff) then test ;
clc;
clear;
fs=48e3;
f0=1e3;
T=1;
N=1:T*fs;
t=N/fs;
wav=sin(2*pi*f0*t).’;
adw=audioDeviceWriter(‘SampleRate’,fs);
wav2=wav;
wav2=wav+1e-18*j*ones(size(wav));
playbuff2=[wav2];
playbuff=[wav];

adw(playbuff2);
pause(3);
adw(playbuff);when i use ifft() to process and get a frame of audio data but forget to real() the results, it sounds weired.
