hello everyone,

I want to realize the function of VAD (voice active detection). In matlab, I use the model of Multiply Accumulate calculate the energy of a frame. However, I can't find the correspondent model in SigmaStudio. Are there VAD model in SigmaStudio, or are there other ways to get the Multiply Accumulate model in SigmaStudio?

Thanks.

Note：the model of Multiply Accumulate in matlab is followed as

Hello,

The ADAU144x processors have a ready-made Voice Activity Detector in their toolbox. If you're using a ADAU1701 instead, perhaps the design shown at https://ez.analog.com/message/51205#51205 might fill your needs. When working with SigmaStudio, often it's better to "think analog", that is, filters, gains, etc. -- instead of in terms of math algorithms, because the latter are not always transparent in the various toolbox blocks.

Best regards,

Bob
