EZSDK 5.02 AAC LC audio encoding output bitrate

Patel Jignesh

Hello TI,

We are using EZSDK 5.02 with AAC - LC binary (c674x_aaclcenc_01_00_01_00_elf).

We want to know that is it possible to configure audio output bit-rate dynamically ?

Thanks,

Hello,

It supports CBR. In the user guide you could search about IAUDENC1_DynamicParams.

Hi Jignesh,

It is possible to set the bitRte, sampleRate and number of channels dynamically.

Application need to to call control API with SETPARAMS command id and dynamicParams structure having the new Bitrate, sampleRate etc.

Refer appendix A of the AAC Encoder userGuide for supported bitrates for a given sampleRate.
