BufferSpectralT (size_t numFrames=0)

Constructs a BufferSpectralT object of frames numFrames . There is always two channels, where channel 0 is the real component and 1 is the imaginary component.
T *

getReal ()

Returns a pointer to the first sample in the real component channel.
const T *

getReal () const

Returns a const pointer to the first sample in the real component channel.
T *

getImag ()

Returns a pointer to the first sample in the imaginary component channel.
const T *

getImag () const

Returns a const pointer to the first sample in the imaginary component channel.
T *

getChannel (size_t ch)

Returns a pointer offset to the first sample of channel ch .
const T *

getChannel (size_t ch) const

Returns a const pointer offset to the first sample of channel ch .
void

zero (size_t startFrame, size_t numFrames)

Assigns zero to numFrames frames starting at startFrame .
void

zero ()

Sets all samples to the value zero.
void

zeroChannel (size_t ch)

Assigns zero to all samples in channel channel .
void

copy (const BufferT< T > &other)

Copies min( this, other ) channels and frames from other to internal storage.
void

copy (const BufferT< T > &other, size_t numFrames)

Copies numFrames frames from other into internal storage.

requires channel counts to match.
void

copyOffset (const BufferT< T > &other, size_t numFrames, size_t frameOffset, size_t otherFrameOffset)

Copies numFrames frames from other offset by otherFrameOffset into internal storage offset by frameOffset .

requires channel counts to match.
void

copyChannel (size_t channel, const T *otherChannel)

Copies otherChannel to the internal channel channel . Assumes there is at least getNumFrames() samples in otherChannel .
size_t

getNumFrames () const

Returns the number of frames in the buffer.
size_t

getNumChannels () const

Returns the number of channels in the buffer.
size_t

getSize () const

Returns the total size of the buffer (frames * channels).
bool

isEmpty () const

Returns true if number of frames is zero, false otherwise.
T *

getData ()

Returns a pointer to the first sample in the data buffer.
const T *

getData () const

Returns a const pointer to the first sample in the data buffer.
T &

operator[] (size_t n)
const T &
