Hello, where do I download the AAC decoder ? Does it require a license ? How much does it cost ?

Welcome @vizion, to the community!

AAC is not free and requires a license, see e.g. here.

Hi Peter, where do I download the Audio IP package for AAC ? I do know that fees need to be paid to Via LA.

Hi,

you could try the LibHelix , see:

For commercial use ask for license:

• The AAC decode code is from the Helix project and licensed under RealNetwork's RSPL license. For commercial use you're still going to need the usual AAC licensing from Via Licensing. On the ESP32, AAC-SBR is supported (many webradio stations use this to reduce bandwidth even further). The ESP8266, however, does not support it due to a lack of onboard RAM.
