fftinfo~ Reference

Report information about a patcher loaded by pfft~

fftinfo~

Description

fftinfo~ gets info about the fft frames in a patcher loaded by a pfft~. It reports the information when sent a bang or whenever DSP is turned on via a dac~ (fftinfo~ only functions within a pfft~).

Examples

fftinfo~ reports information about the FFT subpatcher in which it is located

Arguments

None.

Attributes

Common Box Attributes

Messages

bang

Causes the FFT window size, the FFT frame size (i.e., the signal vector size inside the patcher loaded by pfft~), and the FFT hop size to be sent out the object's outputs.

signal

Reports the FFT window size, the FFT frame size, and the FFT hop size of the signal network to which it is connected.

Output

int

Out left outlet: The current FFT window size specified by argument to the pfft~ object.

Out middle-left outlet: The current spectral frame size (half the FFT window size).

Out middle-right outlet: The current FFT hop size (i.e., the window size divided by the overlap).

Out right outlet: The full spectrum flag. It indicates whether or not the spectral subpatch of the parent pfft~ object is processing the default half-spectrum FFT frames, or full (mirrored) FFT spectrum frames.
