<h1 id="purpose">Purpose</h1>
<p><strong>FP-AUD-AEC1</strong> STM32Cube Function Pack for Acoustic Echo Cancellation is a specific example fully focused on Acoustic Echo Cancellation and provides an implementation of a USB smart speaker use case with microphone</p>
<p>The package includes the <strong>STM32 AcousticEC library</strong>,that provides an implementation for a real-time echo cancellation routine based on the well-known SPEEX implementation of the MDF algorithm.</p>
<p>The firmware provides implementation example for <strong>NUCLEO-F446RE</strong> board or <strong>NUCLEO-F746ZG</strong> equipped with:</p>
<ul>
<li><strong>X-NUCLEO-CCA01M1</strong>, an expansion board based on the <strong>STA350BW</strong> Sound Terminal® 2.1-channel high-efficiency digital audio output system.</li>
<li><strong>X-NUCLEO-CCA02M2</strong>, an evaluation board based on digital MEMS microphones, designed around STMicroelectronics MP34DT06J digital microphones.</li>
</ul>

<li>To optimize memory footprint and MCU time consumption, v1.1.0 has been redesigned to acquire the audio signal from only 1 microphone. To do so, a different HW configuration for X-NUCLEO-CCA02M2 is needed, as described in UM2824 (v1.1 and above).</li>

<h2 id="important-software-additional-information">Important Software Additional Information</h2>
<ul>
<li>A patch for usbd_core.c file is needed to handle iso in and out incomplete event callback invoked by the AUDIO IN OUT class. The patch (usbd_core_Patch.c), located in user-space (Demonstrations/AEC/Patch), replaces the original file which have been disabled, allowing the whole software structure to work flawlessly.</li>
