Rubber Band JNI - Controlling Real-Time Audio Time-Stretching from Java 3 | 4 | This repository contains an example of real-time pitch-shifting and audio time-stretching in Java. It uses two components. The first component is "a high quality software C++ library for audio time-stretching and pitch-shifting C++ called Rubber Band":http://breakfastquay.com/rubberband/. The second component is a Java audio library called "TarsosDSP":https://github.com/JorenSix/TarsosDSP. To bridge the gap between the two JNI(Java Native Interface) is used. Rubber Band provides a JNI interface and starting from the currently unreleased version 1.8.2, makefiles are provided that make compiling and subsequently using the JNI version of Rubber Band relatively straightforward. 5 | 6 | h2. Running the example 7 | 8 | For recent 64 bits Linux machines and Mac OS X this library provides compiled JNI libraries. To run the example you need to build it, with "Apache Ant" and set the correct @java.library.path@ when running the executable jar. This could be done as follows: 9 | 10 |
git clone https://github.com/JorenSix/RubberBandJNI.git
11 | cd RubberbandJNI/build
12 | ant
13 | cd ..
14 | java -Djava.library.path=lib/ -jar build/RubberBandJNI.jar.
15 |
16 | If this does not work, you perhaps need to compile a JNI library yourself. Below documentation is available to get it working on a Linux machine and Mac OS X.
17 |
18 |
19 | h2. Compiling the Rubber Band JNI library on Debian Linux
20 |
21 | To get the example working several elements need to be in place. 1) To compile Rubber Band a C++ tool-chain needs to be available on your system. This includes a compiler and related tools like @make@. 2) The dependencies for Rubber Band should be installed, otherwise compilation is impossible. 3) A JDK should be installed to compile java files and to provide the JNI header files. Here we assume that a JDK and C++ tool-chain is already available. The rest is explained for Debian 8.1 but should be transferable to any Unix like system.
22 |
23 | To install the dependencies on Debian, install following packages:
24 |
25 | @sudo apt-get install vamp-plugin-sdk libsndfile1-dev libfftw3-dev libvamp-sdk2 libvamp-hostsdk3 libsamplerate0-dev@
26 |
27 | Once the dependencies are installed correctly the following should work:
28 |
29 | # Download and unzip and the latest source code
30 | wget https://bitbucket.org/breakfastquay/rubberband/get/46805fcedf7e.zip
31 | unzip 46805fcedf7e.zip
32 | # Change the working directory
33 | cd breakfastquay-rubberband-46805fcedf7e
34 | # If the dependencies are installed correctly the following will work
35 | ./configure
36 | # Compile the source code
37 | make
38 | # Create the JNI library, set JAVA_HOME to your JDK directory
39 | make jni JAVA_HOME=/usr/lib/jvm/java-7-openjdk-amd64/
40 | # Copy the newly created JAR-file and native library to the lib directory
41 | cp lib/rubberband.jar ../lib/
42 | cp lib/librubberband-jni.so ../lib/
43 | # change the working directory
44 | cd ../build
45 | # Build the RubberBandJNI jar file with Apache Ant
46 | ant
47 | cd ..
48 |
49 | If everything went well there are a few new files on your system. @lib/rubberband.jar@ contains the Java part of the JNI-bridge. @lib/librubberband-jni.so@ contains Rubber Band C++ JNI bridge compiled for your system. @build/RubberBandJNI.jar@ contains the example application of this repository. If those files are created correctly, you are ready to run RubberBandJNI. The application needs to be started with a correct @java.library.path@:
50 |
51 | @java -Djava.library.path=lib/ -jar build/RubberBandJNI.jar@
52 |
53 | Watch out: the order of the options does matter: the @-D@ option should appear before @-jar@. Finally, to clean up remove the previously downloaded source code.
54 |
55 | rm 46805fcedf7e.zip
56 | rm -r breakfastquay-rubberband-46805fcedf7e
57 | #rm lib/rubberband.jar
58 | #rm lib/librubberband-jni.so
59 |
60 | h2. Compiling the Rubber Band JNI library on Mac OS X
61 |
62 | To install the dependencies on Mac OS X the "homebrew":http://brew.sh/ package manager is very helpful:
63 |
64 | brew install http://tuohela.net/irc/vamp-plugin-sdk.rb
65 | brew install fftw
66 | brew install libsamplerate
67 | brew install libsndfile
68 | brew install wget
69 |
70 | To get the makefile working on Mac OS X some changes need to be done. The first change is to correctly name the library with a .dylib instead of an .so:
71 |
72 | DYNAMIC_EXTENSION := .dylib
73 | ...
74 | DYNAMIC_LDFLAGS := -shared
75 | VAMP_LDFLAGS := -shared
76 | LADSPA_LDFLAGS := -shared
77 |
78 |
79 | Finally compile the library by calling @make@. It can complain about missing Then call:
80 |
81 | make
82 | make jni JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk1.8.0_45.jdk/Contents/Home
83 |
84 | If you get complaints about a missing @jni_md.h@ "link the header files, as described here.":https://stackoverflow.com/questions/24996017/jdk-1-8-on-linux-missing-include-file
85 |
86 |
87 | h2. Compiling the Rubber Band JNI library on Debian for Android
88 |
89 |
90 | Install the Android Native Development kit, the NDK, and make sure that ndk-build
91 | is available on your path.
92 |
93 | # Download and unzip and the latest source code
94 | wget https://bitbucket.org/breakfastquay/rubberband/get/46805fcedf7e.zip
95 | unzip 46805fcedf7e.zip
96 | # Change the working directory
97 | cd breakfastquay-rubberband-46805fcedf7e
98 | #
99 | mkdir jni
100 | mkdir libs
101 |
102 | # Configure the application to use stl
103 | echo "APP_STL := gnustl_static" > jni/Application.mk
104 | # Copy the build file to the expected location.
105 | cp Android.mk jni
106 |
107 | Then change @jni/Android.mk@ so that the correct directories are used. For me, the beginning of the file looks like this:
108 |
109 | LOCAL_MODULE := rubberband
110 | LOCAL_MODULE_FILENAME := librubberband-jni
111 | LOCAL_PATH := /home/joren/breakfastquay-rubberband-46805fcedf7e
112 | LOCAL_C_INCLUDES := $(LOCAL_PATH)/rubberband $(LOCAL_PATH)/rubberband/src
113 | RUBBERBAND_PATH := /home/joren/breakfastquay-rubberband-46805fcedf7e
114 | RUBBERBAND_SRC_PATH := $(RUBBERBAND_PATH)/src
115 |
116 | Now you are ready to call @ndk-build@ in the top directory and it should build a library in @libs/armeabi/librubberband-jni.so@:
117 |
118 | [armeabi-v7a] Compile++ arm : rubberband <= SilentAudioCurve.cpp
119 | [armeabi-v7a] Compile++ arm : rubberband <= CompoundAudioCurve.cpp
120 | [armeabi-v7a] Compile++ arm : rubberband <= HighFrequencyAudioCurve.cpp

147 |
148 | Download the free "Visual Studio Community 2015":https://www.visualstudio.com/en-us/products/visual-studio-community-vs.aspx and install it. Make sure that the C/C++ components are installed. Subsequently download the latest "RubberBand source code":https://bitbucket.org/breakfastquay/rubberband/get/46805fcedf7e.zip and place the file that is found in @build/@ of this repository in the top directory of the downloaded Rubberband source tree. Doubleclick it to start Visual Studio Community.
149 |
150 | To make it build successfully make sure that you also have a recent Java JDK on installed your machine. When building the project the following directories need to be set as additional include directories:
151 |
152 | C:\Program Files (x86)\Java\jdk1.8.0_60\include;
153 | C:\Program Files (x86)\Java\jdk1.8.0_60\include\win32
154 |
155 | If all goes wel a build should create a dll named @rubberband-library.dll@ to work correctly with this project it should be renamed @rubberband-jni.dll@.
