ANC with AIC3262 using PurePath

Aleksei Makalov

Hello!

The technical documentation for this codec shows that there is the possibility of Active Noise Cancelation, through to the built-in MiniDSP and PurePath. But in the PurePath Console no libraries were found to work with the TLV320AIC3262YZF EVM. Therefore, it is not possible to configure the MiniDSP in ANC mode. Also on the Internet there are examples of ANC development in PurePath Studio (Home Audio) MiniDSP software, but this software was not provided.

1. How can I develop ANC with PurePath Console?

2. Can you provide the TLV320AIC3262YZF EVM library for PurePath Console?

Hi, Aleksei,

Welcome to E2E, thanks for your interest in our products!

Unfortunately, we are no longer providing support tools for ANC development within our codecs as the on-chip miniDSP does not have enough processing capabilities to perform effective ANC algorithms. The codec can be used in a ANC application to capture and playback the audio signals, but the main processing should be handled by an external DSP.

Hi, Aleksei,

I would recommend you to ask my colleagues on the DSP forums for the best solution available for ANC applications.
