I have a tool which compares two audio wav files frame by frame and returns a grade which gives the level of similarity between the two files.

I have an original wav file and a recording of the wav file, since the two files are almost similar i should get a high score of similarity, yet i get a poor score, mainly due to a very slight delay in the recorded file-leading to frame mismatch

My question is- how do i go about aligning the two audio files exactly using MATLAB, so that a valid frame to frame comparison may be done.

    You should run a series of comparisons, shifting one of the frame in time and calculating the correlation between two. Highest value of correlation will give you time shift between waves.

    I think you can use xcorr to achieve this.
