The Goal of this project is to successfully capture Audio data with maker kit microphone and develop low pass filter and capture data upto maximum frequency of 22Khz.
- include an analog lowpass filter that reduces frequencies above approximately 8KHz.To use technical terms, the 3dB “cutoff frequency” should be between 7.5KHz and 8.0KHz.
- Correctly capture audio signals up to a maximum frequency of 22KHz
- Store audio signals with 16bit precision.
- Include a pressable button that triggers audio capture
- Capture five seconds of audio when triggered (via the button press)
- Upload the captured audio data to the cloud
- Make the captured audio playable via a web browser in either a WAV or MP3 format.
- RC filter
Created our own interface to capture the audio data and convert it to wav file.
