algorithm - Rhythm detection through analyzing the audio spectrum -

-

I am creating a rhythm-based game, and facing many problems with cadence. I get the current spectrum of a gaming song, it looks like float array with 512 float. 256 to represent left and right channels. FFT is also available. But I do not know how to work with that data, I have done some experiments, which are with the scene but he gave me a lot of information. I have googled for some ready algorithm, but there is nothing please Someone can help me, perhaps, some articles related to context, content, rhythm, working with audio spectrum. The code will also be very helpful thanks.

Maybe you have not used the right search terms. Try Google 'tempo detection' or 'beat detection' together with 'code' or 'algorithm'. There are many papers, references, code examples, etc.

Just a few hits:

qt - switch/case statement in C++ with a QString type -

-
I want to use switch-case in my program but the compiler generates an error. How can I use the switch statement with QString ? The compiler gives me this error: The expression of the switch type 'QString' is invalid My code is as follows : boolStopWord (the word QString) {bool flag = false; Switch (word) {case "the": flag = true; break ; "On" case: flag = true; break ; Case "in": flag = true; break ; Case "your": flag = true; break ; Case "near": flag = true; break ; Case "all": flag = true; break ; Case "this": flag = true; break ; } Return flag; } How do I use the switch statement with a Caststring ? You can not use the switch statement in C ++ language with integral or enum types. You can formally enter the square type of object in the switch statement, but this means that the compiler will look for a user-defined conversion to convert it to an integral or enum type.

Python's equivalent for Ruby's define_method? -

What is a Python equivalent for Ruby's define_method , which is the dynamic generation of class methods will allow? (As can be seen in Wikipedia) Functions are first-class objects in Python and assign them The properties of a class or an example can be a way of doing the same thing as a Wikipedia example: colors = {"black": "000", "red": "F00", "green": "0f0", "yellow": "ff0", "blue": "00f", "magenta": "fff", "cyan": "0ff", "white": " FFF "} Class MyStream (ARR): Pass for Name, Code in colors.iteritems (): def _in_colour ( W code = code): return '& lt; Span style = "color:% s" & gt;% s & lt; / Span & gt; ' % (Code, self) setter (histrive, "in_" + name, _in_ color)
