Base class from which all unit analyzers (UAnae) inherit; UAnae (note plural form) can be interconnected via => (standard chuck operator) or via =^ (upchuck operator), specify the the types of and when data is passed between UAnae and UGens. When .upchuck() is invoked on a given UAna, the UAna-chain (UAnae connected via =^) is traversed backwards from the upchucked UAna, and analysis is performed at each UAna along the chain; the updated analysis results are stored in UAnaBlobs.
UAnaBlob m_blob
No description available
complex cval(int index)
Get blob's complex value at index.
complex[] cvals()
Get blob's complex array.
float fval(int index)
Get blob's float value at index.
float[] fvals()

int isUpConnectedTo(UAna right)
Is connected to another uana via =^?
UAnaBlob upchuck()
Initiate analysis at the UAna; returns result.
[ top ]
This object contains results associated with UAna analysis. There is a UAnaBlob associated with every UAna. As a UAna is upchucked, the result is stored in the UAnaBlob's floating point vector and/or complex vector. The intended interpretation of the results depends on the specific UAna.

This UAna computes the Fast Fourier Transform on incoming audio samples, and outputs the result via its UAnaBlob as both the complex spectrum and the magnitude spectrum. A buffering mechanism maintains the previous FFTsize # of samples, allowing FFT's to be taken at any point in time, on demand (via .upchuck() or by upchucking a downstream UAna. The window size (along with an arbitry window shape) is controlled via the .window method. The hop size is complete dynamic, and is throttled by how time is advanced.

This UAna computes the Discrete Cosine Transform on incoming audio samples, and outputs the result via its UAnaBlob as real values in the D.C. spectrum. A buffering mechanism maintains the previous DCT size # of samples, allowing DCT to be taken at any point in time, on demand (via .upchuck() or by upchucking a downstream UAna; see UAna documentation).
