Abstract
A method to detect audio frame losses over a link to a device under test (DUT), such as a User Equipment (UE), includes preparing an input sequence, combining the input sequence into an input audio signal, submitting the input audio signal to an encoder, transporting the encoded signal over the link, obtaining a continuous output audio signal from decoding the transported signal, decomposing the continuous output audio signal into an output sequence, and determining one or more lost frames based on a comparison of one or more characteristics of the input sequence and the output sequence. Preparing the input sequence can include preparing a sequence of a plurality of input snippets, each input snippet having one or more audio characteristics, the preparing such that consecutive input snippets have one or more audio characteristics that differ by a predetermined measure.
