Microchip's Timberwolf family of ZL380xx audio processors is designed with best-in-class noise reduction, stereo echo cancellation, and de-reverberation by using license-free, royalty-free intelligent audio IP algorithms. This dedicated processor offloads the host processor in your design. It is optimized for low power with audio hardware accelerators. Our 1-,2-and 3-mic arrays can be implemented in a linear or triangular configuration for optimal beamforming performance. Timberwolf is proven to pass industry standards, including Amazon Far-Field certification. It offers an 8-band equalizer, up to four digital MIC inputs, and two internal 16 ohm speaker drivers. Use our MiTuner GUI tool for setting your audio path configuration to easily tune for your best audio performance. Accelerate your time-to-market by using our validated reference design.
The ZL38051 is an advanced, multi-array voice processor with sound location and 180 degree beamforming.
