Example text

Audio applications can be divided as follows: • Conversational voice: requirements in terms of delay are heavily influenced by one-way delay; for information loss, requirements are influenced by the fact that human ear is tolerant to a certain amount of distortion of a speech signal; • Voice messaging: requirements are similar in terms of information loss but quiet different in terms of delay where there is more tolerance because of the no direct conversation involved; • Audio streaming: requirements in terms of information loss have to be tighter than classical conversational voice to provide better quality.
