AC3 5.1 to HE-AAC 5.1 (can't get 48kHz)

[MKVCrazy]

Hi, I have been away for a very long time due to my school.

I am so sorry if an answer is posted already but I tried as much as I could and can't find the answer I needed.


I encoded .ac3 5.1 audio to he-aac .mp4 5.1 (48kHz)

and extracted out the .aac from mp4 and muxed it with AVI XviD file.

It worked and the audio are perfectly in sync, no fast motions etc and gives me 5.1 audio with right bitrates I set before.

But there is one problem, the kHz is changed to 24kHz from 48kHz.

Is there anyway to get 48kHz in .aac format?

Is there any audio encoder that will directly encode to .aac instead of making me to extract from .mp4 audio file to get raw aac.

I appreciate your help. :)

HE-AAC is always 24khz because half frequency is always interpolated during playback.

Use CT-AAC encoder. My app will show you how to do it. (job1_EncodeAudio.cmd)
