is_denormal() [1/3]

bool MHAUtils::is_denormal ( mha_real_t  x )

inline

Get the normal-ness of a mha_real_t.

Returns true iff x is not equal to zero and the absolute value of x is smaller than the minimum positive normalized value of mha_real_t.

Parameters

x	A mha_real_t floating point number

Returns

True if x is denormal, false otherwise

is_denormal() [2/3]

bool MHAUtils::is_denormal ( const mha_complex_t &  x )

inline

Get the normal-ness of a complex number.

Overload for mha_complex_t. Returns true iff one or both of real and imaginary part are denormal

Parameters

x	[in] A mha_complex_t number

Returns

True if at least one component of x is denormal, false otherwise

is_denormal() [3/3]

bool MHAUtils::is_denormal ( const std::complex< mha_real_t > &  x )

inline

Get the normal-ness of a complex number.

Overload for std::complex Returns true iff one or both of real and imaginary part are denormal.

Parameters

x	[in] A mha_complex_t number

Returns

True if at least one component of x is denormal, false otherwise

spl2hl()

mha_real_t MHAUtils::spl2hl

(

mha_real_t

f

)

Get the offset of between dB(SPL) and dB(HL) for a given frequency according to ISO 389-7:2005 (freefield); e.g.

an intensity of 22.1 dB(SPL) at 125 Hz is equivalent to 0 dB(HL), so spl2hl(125)=-22.1. Interpolation between mesh points is linear. The correction values for frequencies above 16 kHz are extrapolated."

Parameters

[in]

f

The frequency in Hz for which the offset shall be returned

Returns

The offet between dB(SPL) and dB(HL) at frequency f

Exceptions

MHA_Error

if f<0
