auditok.signal.calculate_energy_single_channel

auditok.signal.calculate_energy_single_channel(data, sample_width)

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
