Transform and visualize spectral density data of sound (stored as flac files) and electrical impulse data (stored as voltage time series .csv). Data collection includes ~6 one-minute recordings per recording. The first project goal is to convert multiple flac files from each sensor and convert into wav files for standard integrated visualizations (raw voltage time series, intensity vs. frequency, power spectrum analysis, FFT, autoregression, etc) with subsequent export for data analysis and granular visualization in Python (with Numpy, Matplotlib, and pymongo libraries) + R, and ultimately a light (e.g., Jaguarscript: fridge) persistent offline storage solution of data and intermediate results, to support multiple sessions of further data science.
