Title: DVB-T: codec and bitrate used for audio only broadcast
Post by: Nessuno on 2012-10-24 16:48:52
Does anybody know which coded and bitrate are used to broadcast audio only sources, e.g. radio stations, in current DVB-T standard for European TV?

I don't know about Europe, but here in South Africa when we had the DVB-T trials they used HE-AAC at 64Kbit/s for the radio channels and TV channels. It didn't sound good at all for me. They could of just removed 64Kbit/s off the video streams and added that to the audio to get 128Kbit/s LC-AAC.
They are stopped the DVB-T trials and are now doing DVB-T2 trials, but I don't have an tuner to check out what thet are using now.

It's MPEG-1 layer 2 (i.e. .mp2) audio, usually at 48kHz sampling rate. Bitrate varies by channel. Some channels are stereo, some mono. I did find a website that listed measured parameters for bitrates in various channels in europe as they vary from time to time. I did a system restore so lost some software that would demux my WTV files and tell me from my USB DVB-T tuner picking up UK free-to-air DVB-T.

Here in slovakia DVB-S and DVB-T are MPEG-1 layer 2 (i.e. .mp2) audio sampled at 48000 Hz with mostly 192 kbit. After doing my recording I can demux it using apps such as PVAstrumento or DG index, then cut / edit using mp3 direct cut and then play / convert / whatever using Foobar 2000.
At least this is my use case.
