Firmware for ESP32 - Audio processing -- 2

**Project Title:** Audio Processing and Speech Recognition on ESP32 with Real Hardware Testing

**Project Description:**

We are looking for a skilled freelancer to work on an exciting audio processing and speech recognition project using the ESP32 WROVER microcontroller, MAX9744 amplifier, and SI4684 (or similar) audio module. The primary goal of this project is to implement and test a range of audio processing features, as well as enable voice recognition using TensorFlow on the ESP32 platform.

**Project Objectives:**

1. Implement 2 Test Cases for Speech Recognition with TensorFlow:
- Configure TensorFlow to recognize the keyword "Hey Buttler."
- Wake up the system upon hearing the keyword.

2. Implement 10 Test Cases for Audio Processing:
- Audio input and output processing.
- DSP processing of square wave signals.
- Feedback signal analysis.
- FFT-based voice analysis.
- Loudness control and equalizer adjustments.
- Microphone signal analysis for voice isolation.
- Real-time system response to dynamic audio sources.

**Hardware Components:**
- ESP32 WROVER
- MAX9744 Amplifier
- SI4684 (or equivalent) audio module (I2S support required)

**Project Timeline:**
- First results expected within 2 weeks.
- Project completion within 4 weeks.

**Deliverables:**
- Fully functional code for ESP32 that meets the test case requirements.
- Documentation and instructions for testing the system.
- Clear and well-documented code with comments.
- Assistance with hardware integration and testing.

**Why This Project Is Exciting:**
- Opportunity to work with real hardware and push the boundaries of audio processing on the ESP32 platform.
- Gain experience in implementing voice recognition using TensorFlow.
- Be part of an innovative project with real-world applications.

If you are a skilled developer with experience in audio processing, ESP32, TensorFlow, and real hardware testing, we invite you to bid on this project. We are excited to collaborate with you and bring this project to life. Please include your relevant experience and qualifications in your bid.

If you have any questions or need further details, please feel free to ask. We look forward to working with a talented freelancer who shares our passion for audio technology and innovation.
