hi everyone.
I am new to AAC and have read a lot about the technical advantages of HE-AAC v2.

No my question would be:
In the mp3 world the flagship encoder is commonly considered LAME. Is there an equivalent in the AAC world?

What is the preferred choice by the community here?
I think the most important consideration is the quality of the encoder, isn't it? So which one would you guys recommend?

many thanks.

Yes, but that gives the impression that HE improves what LC does. While it is technically correct (since it expands the bandwidth), it can be interpreted in the wrong way.

That's why i've put the other example, clearly saying that LC is used for the most important part of the audio, and the SBR is used for the less important part.

LC could have been used for the less important part, but it is not in order to save bitrate.

I still disagree. Why is the outer part of an image less important than the center part? If you look directly at the edges of an image, don't you want them to be artifact-free just like the center part?

SBR works on top of a downsampled "dull sounding" version of the audio to make it brighter. A downsampled image, scaled to its original size, is blurry, and SBR would "sharpen" it.
