Hi
In order to upload a wav file, I think I should be using the wavread command. I tried using that, but it results in an error. I tried using,
y = wavread('C:\Users\Admin\Desktop\audacity\Audacity 1.3 Beta (Unicode)\prompts')
The error says, "invalid wav file".
I need to upload two files which I have recorded and find out the delay between them.I have figured out how to find delay by considering sample waves, but not how to upload the files and then calculate the time delay. Could someone please help with uploading the files and then tell me how to use them normally like any waves generated in the matlab?
Thanks in advance

i hope this may help u.
[FileName,PathName] = uigetfile('*.wav');
PathOriginal=sprintf('%s%s',PathName,FileName);
[xt,fs]=wavread(PathOriginal);
from here manage ur code. here xt is lenth of signal and 'fs' is sampling rate of wav format. and it is common for all wav formats : its value is 44.1k

Matlab's documentation is a high quality source of explanations:
Type this in the command window:
help uigetfile
doc uigetfile
(and the same for "sprintf" and "wavread")
