Does AAC Encoder support anything other than 16bit audio?

Hi,

I was wandering if the IPP aac encoder can encode PCM audio with 24 bits per sample? I've tried setting the encoder_params.m_info_in.bitPerSample to 24, but then the encoder always seems to expect 16bit audio, is this correct?

Thanks,
Michael

Hi,

You are right.
The IPP AAC encoder can encode PCM audio with 16 bits per samples only.

In fact, the encoder converts the 16bit buffer to 32bit internal buffer before encoding.
You can easily bypass it and add 32bit support yourself.
