Hi

Does any one have technical details on the type of audio encoding to be deployed on the DTT service? I.e. AAC etc?

Thanks

Primary audio is going to be HE-AAC in stereo, using LATM/LAOS encapsulation, which is a DVB standard. Channels may also decide to use AC-3 for surround sound.

One issue at present is that a lot of the mainstream DVB software for PCs doesn't support LATM encapsulated AAC. I've been covering some of the issues at http://www.mythtv.co.nz
