One is a standard calibrated mic and other is mic in question. Can any one suggest me a formula to quantify by how much percentage or units the two recordings differer? I am interested only in amplitude variations over time and i have instantaneous amplitudes of both the recordings at all points in time. Thanking all Regards Ajith Mr.Ajith Kumar U Doctoral Student, Department of Audiology, All India Institute of Speech and Hearing, Naimisham Camppus, Manasagangothri, Mysore,570006 INDIA.
