SineTable()

Common::SineTable::SineTable

(

Parameters

nPoints

Number of distinct radian points, which must be in range [16,65536] and be divisible by 4

Member Function Documentation

getTable()

const float* Common::SineTable::getTable ( )

inline

Get pointer to table

This table contains nPoints/2 entries. Prefer to use at() The layout of this table is as follows:

• Entries 0 up to (excluding) nPoints/4: sin(0) till (excluding) sin(1/2*pi)
• Entries 2_nPoints/4 up to nPoints/2: sin(pi) till (excluding) sin(3/2*pi)

at()

float Common::SineTable::at

(

int

index

)

const

Returns sin(2*pi * index / nPoints ) Index must be in range [0, nPoints - 1] Faster than atLegacy

atLegacy()

float Common::SineTable::atLegacy

(

int

index

)

const

Returns sin(2*pi * index / nPoints ) Index must be in range [0, nPoints - 1]
