Build an *STM32 USB Host Audio device* that allows your STM32 to connect to a USB speaker and play WAV audio files stored on an SD card.

In this tutorial, we configure the STM32 as a *USB Host* using STM32CubeMX and STM32CubeIDE. We use the USB Audio Class to communicate with a USB speaker, while an SD card provides the audio files that will be played through the USB connection.

We configure the USB Host Audio Class, read WAV files from the SD card, process the audio data, and transfer the samples to the connected USB speaker. This demonstrates how STM32 can combine USB Host, SD card storage, and audio processing to build a practical embedded audio player.
