NeroAACEnc sample rate error #72

Closed BiatuAutMiahn closed 5 years ago

BiatuAutMiahn commented 6 years ago

If the sample rate of the file is too low (ie; 11025 Hz) throws an error, had to use ffmpeg to fix it, then the file converted successfully, however 22050 worked just fine

Hello.

I need more details. Converting 11.025 Hz file with NeroAacEnc works fine for me:

Regards, MuldeR

BTW: Anyway, don't expect any fixes for NeroAacEnc. Development is dead for years...

lordmulder commented 5 years ago

Did not provide more information, so closing this one.

BiatuAutMiahn commented 5 years ago

Sorry for delay, is there any good alternatives to NeroAAC? It's the best i've come across so far imo

lordmulder commented 5 years ago

People tend to agree that Apple's AAC encoder is the best these days 🤧

Apple's AAC encoder is available as a command-line tool thanks to QAAC, but you still need to download and install Apple's CoreAudioToolbox in one way or another. QAAC really is just a front-end.

See here for details: http://lamexp.sourceforge.net/doc/Manual.html#qaac-apple-aac-encoder
