Audio for mobile TV presents new challenges. All use highly bit rate reduced audio coding schemes. The dynamic range “comfort zone” used for mixing television audio for viewing on stereo or surround in-the-home televisions will be far too wide for comfortable listening on typical earbuds or the tiny speakers in the mobile TV. Background noise in many environments will define a relatively high loudness floor; if the volume is increased for acceptable intelligibility on soft passages, loud passages run the risk of causing hearing damage. Dialogue intelligibility response is another consideration for these less-than-ideal transducers. To resolve this, Linear Acoustic has created AERO.mobile, an audio loudness manager for mobile DTV.
