 TITLE:: FluidNMFMatch
-SUMMARY:: Real-Time Non-Negative Matrix Factorisation on Buffered Dictionaries
+SUMMARY:: Real-Time Non-Negative Matrix Factorisation with Fixed Dictionaries
 CATEGORIES:: Libraries>FluidDecomposition
 RELATED:: Guides/FluCoMa, Guides/FluidDecomposition, Classes/FluidBufNMF
 
 DESCRIPTION::
-The FluidBufNMF object provides the activation (linked to amplitude) for each pre-defined dictionaries (similar to spectra) predefined in a buffer. These dictionaries would have usually be computed through an offline Non-Negative Matrix Factorisation (NMF) footnote:: Lee, Daniel D., and H. Sebastian Seung. 1999. ‘Learning the Parts of Objects by Non-Negative Matrix Factorization’. Nature 401 (6755): 788–91. https://doi.org/10.1038/44565 :: with the link::Classes/FluidBufNMF:: UGen. NMF has been a popular technique in signal processing research for things like source separation and transcription footnote:: Smaragdis and Brown, Non-Negative Matrix Factorization for Polyphonic Music Transcription.::, although its creative potential is so far relatively  unexplored.
+The FluidNMFMatch object matches an incoming audio signal against a set of spectral templates using an slimmed-down version of Nonnegative Matrix Factorisation (NMF) footnote:: Lee, Daniel D., and H. Sebastian Seung. 1999. ‘Learning the Parts of Objects by Non-Negative Matrix Factorization’. Nature 401 (6755): 788–91. https://doi.org/10.1038/44565. ::
 
-The algorithm takes a buffer in which provides a spectral definition of a number of components, determined by the rank argument and the dictionary buffer channel count. It works iteratively, by trying to find a combination of amplitudes ('activations') that yield the original magnitude spectrogram of the audio input when added together. By and large, there is no unique answer to this question (i.e. there are different ways of accounting for an evolving spectrum in terms of some set of templates and envelopes). In its basic form, NMF is a form of unsupervised learning: it starts with some random data and then converges towards something that minimizes the distance between its generated data and the original:it tends to converge very quickly at first and then level out. Fewer iterations mean less processing, but also less predictable results.
+It outputs at kr the degree of detected match for each template (the activation amount, in NMF-terms). The spectral templates are presumed to have been produced by the offline NMF process (link::Classes/FluidBufNMF::), and must be the correct size with respect to the FFT settings being used (FFT size / 2 + 1 frames long). The rank of the decomposition is determined by the number of channels in the supplied buffer of templates, up to a maximum set by the STRONG::maxRank:: parameter.

 The whole process can be related to a channel vocoder where, instead of fixed bandpass filters, we get more complex filter shapes and the activations correspond to channel envelopes.
 
 More information on possible musicianly uses of NMF are availabe in LINK::Guides/FluCoMa:: overview file.

+The real-time processing method. It takes an audio or control input, and will yield a control stream in the form of a multichannel array of size STRONG::maxRank:: . If the dictionary buffer has fewer than maxRank channels, the remaining outputs will be zeroed.
 
 ARGUMENT:: in
-The input to the factorisation process.
+The signal input to the factorisation process.
 
 ARGUMENT:: dictBufNum
-	The index of the buffer where the different dictionaries will be matched against. Dictionaries must be STRONG::(fft size / 2) + 1:: frames and STRONG::rank:: channels
+	The server index of the buffer containing the different dictionaries that the input signal will be matched against. Dictionaries must be STRONG::(fft size / 2) + 1:: frames. If the buffer has more than STRONG::maxRank:: channels, the excess will be ignored.
 
-ARGUMENT:: rank
-	The number of elements the NMF algorithm will try to divide the spectrogram of the source in. This should match the number of channels of the dictBuf defined above.
+ARGUMENT::maxRank
+	The maximum number of elements the NMF algorithm will try to divide the spectrogram of the source in. This dictates the number of output channelsfor the ugen.
 
 ARGUMENT:: nIter
-	The NMF process is iterative, trying to converge to the smallest error in its factorisation. The number of iterations will decide how many times it tries to adjust its estimates. Higher numbers here will be more CPU expensive, lower numbers will be more unpredictable in quality.

 ARGUMENT:: winSize

+	The number of samples that are analysed at a time. A lower number yields greater temporal resolution, at the expense of spectral resoultion, and vice-versa.
 
 ARGUMENT:: hopSize
-	The window hope size. As NMF relies on spectral frames, we need to move the window forward. It can be any size but low overlap will create audible artefacts.
