3. ALIEN VOICE EFFECT
In this exercise, we will create a simple voice effect, namely taking the microphone's input signal and producing an "alien" version of it. During the implementation, we will come across a few limitations that arise when trying to realize digital signal processing (DSP) in real-time.
In Section 3.1, we will explain the effect that we will be implementing. In Section 3.2, we will discuss some important points that need to be considered when implementing real-time DSP. In Section 3.3, we propose a Python framework for simulating a real-time environment with your laptop's sound card the sounddevice library. Finally, we will guide you through the implementation on the STM32 board in Section 3.4.
As in the previous chapter, text contained in highlighted boxes, as shown below, will require you to determine the appropriate solution and implementation.
