[y,fs] = audioread('damn-it.wav');
plot(y); ----
when this code runs audio is stored in 'y' and on plotting ,it shows numbers from zero to 17658 on x-axis. I want to know amplitude at different times so x-axis unit in secs(here 'usec') is desired.

t = (0:size(y,1)-1)/fs;
plot(t, y)

Thank you,Yes, you are right. But sum(ismembertol(y, 0.1)); is also not tolerant enough for 16 bit signed representation of wav files. Its giving zero for every values.
