- Open Chrome or any app by clapping twice, inspired by Tony Stark.
- Analyzed clap sound using Fourier transform, finding energy concentrated at 1.4kHz to 1.8kHz.
- Implemented a bandpass filter to isolate clap sounds and ignore noise.
- Used peak detection to recognize claps in real time.
- System launches Chrome or any defined command upon detecting two claps with minimum spacing.
- Required libraries include numpy, pyaudio, scipy, pywin32, PyAudio, pygame, SpeechRecognition, dotenv, gTTS, langchain, langchain-core, langchain-google, and scipy.
- Reminder to set Google API key in a .env file, available under Google's free tier.
