A method is provided to compare recordings that includes providing a list of a plurality of recordings and selecting at least a first recording and a second recording from the plurality of recordings. The first recording and the second recording have predetermined lengths The method also includes selecting a first portion of the first recording, identifying a second portion of the second recording based on the first portion, and comparing the first portion to the second portion When the entire length of the recording is selected as the first portion, the entire length of the second recording can be identified as the second portion. Identifying a second portion may also include normalizing it to the first portion. Also, identifying the second portion can include translating the first portion into a wave-form searching the second recording for another wave-form similar to the translated wave-form and matching the translated wave form with the similar wave-form.
