  1 | 		   GNU LESSER GENERAL PUBLIC LICENSE
  2 |                        Version 3, 29 June 2007
  3 | 
  4 |  Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
  5 |  Everyone is permitted to copy and distribute verbatim copies
  6 |  of this license document, but changing it is not allowed.
  7 | 
  8 | 
  9 |   This version of the GNU Lesser General Public License incorporates
 10 | the terms and conditions of version 3 of the GNU General Public
 11 | License, supplemented by the additional permissions listed below.
 12 | 
 13 |   0. Additional Definitions.
 14 | 
 15 |   As used herein, "this License" refers to version 3 of the GNU Lesser
 16 | General Public License, and the "GNU GPL" refers to version 3 of the GNU
 17 | General Public License.
 18 | 
 19 |   "The Library" refers to a covered work governed by this License,
 20 | other than an Application or a Combined Work as defined below.
 21 | 
 22 |   An "Application" is any work that makes use of an interface provided
 23 | by the Library, but which is not otherwise based on the Library.
 24 | Defining a subclass of a class defined by the Library is deemed a mode
 25 | of using an interface provided by the Library.
 26 | 
 27 |   A "Combined Work" is a work produced by combining or linking an
 28 | Application with the Library.  The particular version of the Library
 29 | with which the Combined Work was made is also called the "Linked
 30 | Version".
 31 | 
 32 |   The "Minimal Corresponding Source" for a Combined Work means the
 33 | Corresponding Source for the Combined Work, excluding any source code
 34 | for portions of the Combined Work that, considered in isolation, are
 35 | based on the Application, and not on the Linked Version.
 36 | 
 37 |   The "Corresponding Application Code" for a Combined Work means the
 38 | object code and/or source code for the Application, including any data
 39 | and utility programs needed for reproducing the Combined Work from the
 40 | Application, but excluding the System Libraries of the Combined Work.
 41 | 
 42 |   1. Exception to Section 3 of the GNU GPL.
 43 | 
 44 |   You may convey a covered work under sections 3 and 4 of this License
 45 | without being bound by section 3 of the GNU GPL.
 46 | 
 47 |   2. Conveying Modified Versions.
 48 | 
 49 |   If you modify a copy of the Library, and, in your modifications, a
 50 | facility refers to a function or data to be supplied by an Application
 51 | that uses the facility (other than as an argument passed when the
 52 | facility is invoked), then you may convey a copy of the modified
 53 | version:
 54 | 
 55 |    a) under this License, provided that you make a good faith effort to
 56 |    ensure that, in the event an Application does not supply the
 57 |    function or data, the facility still operates, and performs
 58 |    whatever part of its purpose remains meaningful, or
 59 | 
 60 |    b) under the GNU GPL, with none of the additional permissions of
 61 |    this License applicable to that copy.
 62 | 
 63 |   3. Object Code Incorporating Material from Library Header Files.
 64 | 
 65 |   The object code form of an Application may incorporate material from
 66 | a header file that is part of the Library.  You may convey such object
 67 | code under terms of your choice, provided that, if the incorporated
 68 | material is not limited to numerical parameters, data structure
 69 | layouts and accessors, or small macros, inline functions and templates
 70 | (ten or fewer lines in length), you do both of the following:
 71 | 
 72 |    a) Give prominent notice with each copy of the object code that the
 73 |    Library is used in it and that the Library and its use are
 74 |    covered by this License.
 75 | 
 76 |    b) Accompany the object code with a copy of the GNU GPL and this license
 77 |    document.
 78 | 
 79 |   4. Combined Works.
 80 | 
 81 |   You may convey a Combined Work under terms of your choice that,
 82 | taken together, effectively do not restrict modification of the
 83 | portions of the Library contained in the Combined Work and reverse
 84 | engineering for debugging such modifications, if you also do each of
 85 | the following:
 86 | 
 87 |    a) Give prominent notice with each copy of the Combined Work that
 88 |    the Library is used in it and that the Library and its use are
 89 |    covered by this License.
 90 | 
 91 |    b) Accompany the Combined Work with a copy of the GNU GPL and this license
 92 |    document.
 93 | 
 94 |    c) For a Combined Work that displays copyright notices during
 95 |    execution, include the copyright notice for the Library among
 96 |    these notices, as well as a reference directing the user to the
 97 |    copies of the GNU GPL and this license document.
 98 | 
 99 |    d) Do one of the following:
100 | 
101 |        0) Convey the Minimal Corresponding Source under the terms of this
102 |        License, and the Corresponding Application Code in a form
103 |        suitable for, and under terms that permit, the user to
104 |        recombine or relink the Application with a modified version of
105 |        the Linked Version to produce a modified Combined Work, in the
106 |        manner specified by section 6 of the GNU GPL for conveying
107 |        Corresponding Source.
108 | 
109 |        1) Use a suitable shared library mechanism for linking with the
110 |        Library.  A suitable mechanism is one that (a) uses at run time
111 |        a copy of the Library already present on the user's computer
112 |        system, and (b) will operate properly with a modified version
113 |        of the Library that is interface-compatible with the Linked
114 |        Version.
115 | 
116 |    e) Provide Installation Information, but only if you would otherwise
117 |    be required to provide such information under section 6 of the
118 |    GNU GPL, and only to the extent that such information is
119 |    necessary to install and execute a modified version of the
120 |    Combined Work produced by recombining or relinking the
121 |    Application with a modified version of the Linked Version. (If
122 |    you use option 4d0, the Installation Information must accompany
123 |    the Minimal Corresponding Source and Corresponding Application
124 |    Code. If you use option 4d1, you must provide the Installation
125 |    Information in the manner specified by section 6 of the GNU GPL
126 |    for conveying Corresponding Source.)
127 | 
128 |   5. Combined Libraries.
129 | 
130 |   You may place library facilities that are a work based on the
131 | Library side by side in a single library together with other library
132 | facilities that are not Applications and are not covered by this
133 | License, and convey such a combined library under terms of your
134 | choice, if you do both of the following:
135 | 
136 |    a) Accompany the combined library with a copy of the same work based
137 |    on the Library, uncombined with any other library facilities,
138 |    conveyed under the terms of this License.
139 | 
140 |    b) Give prominent notice with the combined library that part of it
141 |    is a work based on the Library, and explaining where to find the
142 |    accompanying uncombined form of the same work.
143 | 
144 |   6. Revised Versions of the GNU Lesser General Public License.
145 | 
146 |   The Free Software Foundation may publish revised and/or new versions
147 | of the GNU Lesser General Public License from time to time. Such new
148 | versions will be similar in spirit to the present version, but may
149 | differ in detail to address new problems or concerns.
150 | 
151 |   Each version is given a distinguishing version number. If the
152 | Library as you received it specifies that a certain numbered version
153 | of the GNU Lesser General Public License "or any later version"
154 | applies to it, you have the option of following the terms and
155 | conditions either of that published version or of any later version
156 | published by the Free Software Foundation. If the Library as you
157 | received it does not specify a version number of the GNU Lesser
158 | General Public License, you may choose any version of the GNU Lesser
159 | General Public License ever published by the Free Software Foundation.
160 | 
161 |   If the Library as you received it specifies that a proxy can decide
162 | whether future versions of the GNU Lesser General Public License shall
163 | apply, that proxy's public statement of acceptance of any version is
164 | permanent authorization for you to choose that version for the
165 | Library.

 36 | 
 37 |  Theory:
 38 | 
 39 |  Trigger detection is performed using a trail of moving averages, 
 40 |  
 41 |  The FFT input is broken up into 128 ranges and averaged, each range has two moving 
 42 |  averages that tail each other at a rate of (1.0 / BD_DETECTION_RATE) seconds.  
 43 | 
 44 |  Each time the moving average for a range exceeds it's own tailing average by:
 45 | 
 46 |  (moving_average[range] * BD_DETECTION_FACTOR >= moving_average[range])
 47 | 
 48 |  if this is true there's a rising edge and a detection is flagged for that range. 
 49 |  Next a trigger gap test is performed between rising edges and timestamp recorded. 
 50 | 
 51 |  If the gap is larger than our BPM window (in seconds) then we can discard it and
 52 |  reset the timestamp for a new detection -- but only after checking to see if it's a 
 53 |  reasonable match for 2* the current detection in case it's only triggered every
 54 |  other beat. Gaps that are lower than the BPM window are ignored and the last 
 55 |  timestamp will not be reset.  
 56 | 
 57 |  Gaps that are within a reasonable window are run through a quality stage to determine 
 58 |  how 'close' they are to that channel's current prediction and are incremented or 
 59 |  decremented by a weighted value depending on accuracy. Repeated hits of low accuracy 
 60 |  will still move a value towards erroneous detection but it's quality will be lowered 
 61 |  and will not be eligible for the gap time quality draft.
 62 |  
 63 |  Once quality has been assigned ranges are reviewed for good match candidates and if 
 64 |  BD_MINIMUM_CONTRIBUTIONS or more ranges achieve a decent ratio (with a factor of 
 65 |  BD_QUALITY_TOLERANCE) of contribution to the overall quality we take them into the 
 66 |  contest round.  Note that the contest round  won't run on a given process() call if 
 67 |  the total quality achieved does not meet or exceed BD_QUALITY_TOLERANCE.
 68 |   
 69 |  Each time through if a select draft of BPM ranges has achieved a reasonable quality 
 70 |  above others it's awarded a value in the BPM contest.  The BPM contest is a hash 
 71 |  array indexed by an integer BPM value, each draft winner is awarded BD_QUALITY_REWARD.
 72 | 
 73 |  Finally the BPM contest is examined to determine a leader and all contest entries 
 74 |  are normalized to a total value of BD_FINISH_LINE, whichever range is closest to 
 75 |  BD_FINISH_LINE at any given point is considered to be the best guess however waiting 
 76 |  until a minimum contest winning value of about 20.0-25.0 will provide more accurate 
 77 |  results.  Note that the 20-25 rule may vary with lower and higher input ranges. 
 78 |  A winning value that exceeds 40 or hovers around 60 (the finish line) is pretty much
 79 |  a guaranteed match.
 80 | 
 81 | 
 82 |  Configuration Kernel Notes:
 83 | 
 84 |  The majority of the ratios and values have been reverse-engineered from my own  
 85 |  observation and visualization of information from various aspects of the detection 
 86 |  triggers; so not all parameters have a perfect definition nor perhaps the best value yet.
 87 |  However despite this it performs very well; I had expected several more layers 
 88 |  before a reasonable detection would be achieved. Comments for these parameters will be 
 89 |  updated as analysis of their direct effect is explored.
 90 | 
 91 | 
 92 |  Input Restrictions:
 93 | 
 94 |  bpm_maximum must be within the range of (bpm_minimum*2)-1
 95 |  i.e. minimum of 50 must have a maximum of 99 because 50*2 = 100
 96 | 
 97 | 
 98 |  Changelog: 
 99 |  
100 |  01/17/2010 - Charles J. Cliffe 
101 |   - Tested and tweaked default kernel values for tighter detection
102 |   - Added BeatDetektor.config_48_95, BeatDetektor.config_90_179 and BeatDetektor.config_150_280 for more refined detection ranges
103 |   - Updated unit test to include new range config example
104 | 
105 | 02/21/2010 - Charles J. Cliffe 
106 |  - Fixed numerous bugs and divide by 0 on 1% match causing poor accuracy
107 |  - Re-worked the quality calulations, accuracy improved 8-10x
108 |  - Primary value is now a fractional reading (*10, just divide by 10), added win_bpm_int_lo for integral readings
109 |  - Added feedback loop for current_bpm to help back-up low quality channels
110 |  - Unified range configs, now single default should be fine
111 |  - Extended quality reward 'funnel'
