 Key Features:
 - Live waveform and spectrum plotting using Matplotlib.
 - Configurable audio parameters (sample rate, window size).
+- Variable display refresh rate.
 - Device selection from available system audio inputs.
 - VU meters for different frequency bands.
-- Pushes computed spectrum data (10 frequency bins) and rms to a Redis server.
+- Pushes analysis data to Redis, including spectrum, waveform, RMS, and frequency bins.
 - Dark theme for the GUI using sv_ttk.
 
+Redis Keys:
+- 'Db': The full magnitude spectrum data (NumPy array, serialized to bytes).
+- 'wave': The raw audio waveform data (NumPy array, serialized to bytes).
+- 'spectrum_10': A string representation of a list of levels for the VU meter frequency bins (0-10).
+- 'rms': The Root Mean Square of the raw audio signal (string).
