calculate_energy_single_channel
(data, sample_width)[source]¶ Calculate the energy of mono audio data. Energy is computed as:
\[energy = 20 \log(\sqrt({1}/{N}\sum_{i}^{N}{a_i}^2)) % # noqa: W605\]where a_i is the i-th audio sample and N is the number of audio samples in data.
Parameters: - data (bytes) – single-channel audio data.
- sample_width (int) – size in bytes of one audio sample.
Returns: energy – energy of audio signal.
Return type: float
