How do I select between LC-AAC and HE-AAC, or... #55

Closed Starlite528 closed 6 years ago

Or what profile does the Nero AAC encoder use? I'm trying to re-convert some AAC audio files that for some reason my car radio is not accepting.

Hi.

You can enforce a specific AAC profile on the "Advanced Options" page. But it is recommended to keep the default, i.e. let Nero AAC decide automatically based on the target bitrate. HE-AAC (or even HE-AACv2) generally is only advantageous at very low bitrates. It is actually detrimental for the higher bitrates! So let the encoder decided what to use.

Best Regards, MuldeR

BTW: HE-AAC(v2) is fully backwards-compatible to LC-AAC. HE-AAC is just LC-AAC+SBR. Decoders that don't know about HE-AAC (SBR) will decode it as normal LC-AAC.
