A simple android app with the following requirements:
1. continuously sample from the external microphone @ 8kHz.
2. process the sampled data (general filtering, etc) in realtime.
3. plot the processed data in realtime, like an oscilloscope. The x-axis must be configurable (e.g. 1sec, 2sec, 3sec long). y-axis should be dynamic to display the full amplitude of the data.
4. record the sampled data from start to finish.
must deliver in a week. people with digital signal processing experience preferred.
Hi, I read your interesting project. I have completed projects similar to record and display real-time data. I also have extensive experience in digital signal processing.
