Detailed Description

template<typename T>
class edsp::feature::temporal::leq< T >

This class estimates the Equivalent Continuous Sound Level over consecutive frames.

Leq is the preferred method to describe sound levels that vary over time, resulting in a single decibel value which takes into account the total sound energy over the period of time of interest

Member Typedef Documentation

size_type

template<typename T>

using edsp::feature::temporal::leq< T >::size_type = std::size_t

value_type

template<typename T>

using edsp::feature::temporal::leq< T >::value_type = T

Constructor & Destructor Documentation

leq()

template<typename T >

edsp::feature::temporal::leq< T >::leq ( leq< T >::size_type  number_frames )

inlineexplicit

Creates a leq estimator.

Parameters

number_frames

Number of frames over time of interest to compute the equivalent sound level.

~leq()

template<typename T>

edsp::feature::temporal::leq< T >::~leq ( )

default

Default destructor.

Member Function Documentation

extract()

template<typename T >

template<typename ForwardIt >

leq< T >::value_type edsp::feature::temporal::leq< T >::extract ( ForwardIt  first, ForwardIt  last  )

inline

Estimates the equivalent sound level over time of the frame represented by the elements in the range [first, last).

Note

Frames can have different lengths but it is preferable to keep consistency between consecutive frames.

Parameters

first	Forward iterator defining the begin of the range to examine.
last	Forward iterator defining the end of the range to examine.

Returns

The estimated equivalent sound level in dB.
