|
|
## 1. Code components
|
|
|
|
Rubber Band consists of:
|
|
|
|
* The Rubber Band Library code. This is the code that will normally
|
|
be used by your applications. The headers for this are in the
|
|
rubberband/ directory, and the source code is in src/.
|
|
The Rubber Band Library may also depend upon external resampler
|
|
and FFT code; see section 3a below for details.
|
|
|
|
* The Rubber Band command-line tool. This is in main/main.cpp.
|
|
This program uses Rubber Band Library and also requires libsndfile
|
|
(http://www.mega-nerd.com/libsndfile/, licensed under the GNU Lesser
|
|
General Public License) for audio file loading.
|
|
|
|
* A pitch-shifter LADSPA audio effects plugin. This is in ladspa/.
|
|
It requires the LADSPA SDK header ladspa.h (not included).
|
|
|
|
* A Vamp audio analysis plugin which may be used to inspect the
|
|
dynamic stretch ratios and other decisions taken by the Rubber Band
|
|
Library when in use. This is in vamp/. It requires the Vamp
|
|
plugin SDK (https://www.vamp-plugins.org/develop.html) (not included).
|
|
|
|
|
|
## 2. Using the Rubber Band command-line tool
|
|
|
|
The Rubber Band command-line tool builds as bin/rubberband. The basic
|
|
incantation is
|
|
|
|
```
|
|
$ rubberband -t <timeratio> -p <pitchratio> <infile.wav> <outfile.wav>
|
|
```
|
|
|
|
For example,
|
|
|
|
```
|
|
$ rubberband -t 1.5 -p 2.0 test.wav output.wav
|
|
```
|
|
|
|
stretches the file test.wav to 50% longer than its original duration,
|
|
shifts it up in pitch by one octave, and writes the output to output.wav.
|
|
|
|
Several further options are available: run "rubberband -h" for help.
|
|
In particular, different types of music may benefit from different
|
|
"crispness" options (-c flag with a numerical argument from 0 to 6).
|
|
|
|
|
|
## 3. Using Rubber Band Library
|
|
|
|
Rubber Band has a public API that consists of one C++ class, called
|
|
`RubberBandStretcher` in the `RubberBand` namespace. You should
|
|
`#include <rubberband/RubberBandStretcher.h>` to use this class.
|
|
There is extensive documentation in the class header.
|
|
|
|
A header with C language bindings is also provided in
|
|
`<rubberband/rubberband-c.h>`. This is a wrapper around the C++
|
|
implementation, and as the implementation is the same, it also
|
|
requires linkage against the C++ standard libraries. It is not yet
|
|
documented separately from the C++ header. You should include only
|
|
one of the two headers, not both.
|
|
|
|
A .NET interface is also included, contributed by Jonathan Gilbert;
|
|
see the files in the `dotnet` directory for details.
|
|
|
|
The source code for the command-line utility (`main/main.cpp`)
|
|
provides a good example of how to use Rubber Band in offline mode; the
|
|
LADSPA pitch shifter plugin (`ladspa/RubberBandPitchShifter.cpp`) may
|
|
be used as an example of Rubber Band in real-time mode.
|
|
|
|
IMPORTANT: Please ensure you have read and understood the licensing
|
|
terms for Rubber Band before using it in your application. This
|
|
library is provided under the GNU General Public License, which means
|
|
that any application that uses it must also be published under the GPL
|
|
or a compatible licence (i.e. with its full source code also available
|
|
for modification and redistribution) unless you have separately
|
|
acquired a commercial licence from the author.
|
|
|
|
|
|
## 4. Compiling Rubber Band Library
|
|
|
|
The primary supported build system for Rubber Band on all platforms is
|
|
Meson (https://mesonbuild.com). The Meson build system can be used to
|
|
build all targets (static and dynamic library, command-line utility,
|
|
and plugins) and to cross-compile.
|
|
|
|
☞ If you only need a static library and don't wish to use Meson, some
|
|
alternative build files (Makefiles and Visual C++ projects) are
|
|
included in the `otherbuilds` directory. See the platform-specific
|
|
build sections below for more details.
|
|
|
|
☞ If you want to include Rubber Band in a C++ project and would prefer
|
|
not to compile a separate library, there is a single `.cpp` file at
|
|
`single/RubberBandSingle.cpp` which can be added to your project
|
|
as-is. It produces a single compilation-unit build with the built-in
|
|
FFT and resampler implementations with no further library
|
|
dependencies. See the comments at the top of that file for more
|
|
information.
|
|
|
|
To build with Meson, ensure Meson and Ninja are installed and run:
|
|
|
|
```
|
|
$ meson build && ninja -C build
|
|
```
|
|
|
|
This checks for necessary dependencies, reports what it finds, and if
|
|
all is well, builds the code into a subdirectory called `build`. It
|
|
will build everything it can find the requisite dependencies for:
|
|
static and dynamic libraries, LADSPA and Vamp plugins, and
|
|
command-line utility.
|
|
|
|
Some configuration options are provided, described in the
|
|
`meson_options.txt` file. To set one of these, add a `-D` option to
|
|
Meson:
|
|
|
|
```
|
|
$ meson build -Dipp_path=/opt/intel/ipp
|
|
```
|
|
|
|
The options are documented in the library- and platform-specific
|
|
sections below.
|
|
|
|
Rubber Band Library is written entirely in C++ to the C++98
|
|
standard. It is unlikely to make any difference (performance or
|
|
otherwise) which C++ standard your compiler uses - as long as it's no
|
|
older than C++98!
|
|
|
|
If you are building this software using either of the Speex or KissFFT
|
|
library options, please be sure to review the terms for those
|
|
libraries in `src/speex/COPYING` and `src/kissfft/COPYING` as
|
|
applicable.
|
|
|
|
|
|
### 4a. Building on Linux
|
|
|
|
For best results, and to ensure the command-line tool and plugins are
|
|
built, first install libsamplerate, libsndfile, and the LADSPA and
|
|
Vamp plugin headers so they can be found using `pkg-config`. Then
|
|
|
|
```
|
|
$ meson build && ninja -C build
|
|
```
|
|
|
|
See "FFT and resampler selection" below for further build options.
|
|
|
|
Alternatively, if you only need the static library and prefer a
|
|
Makefile, try
|
|
|
|
```
|
|
$ make -f otherbuilds/Makefile.linux
|
|
```
|
|
|
|
|
|
### 4b. Building on macOS
|
|
|
|
Ensure the Xcode command-line tools are installed, and ideally also
|
|
install libsamplerate and libsndfile.
|
|
|
|
To build for the default architecture:
|
|
|
|
```
|
|
$ meson build && ninja -C build
|
|
```
|
|
|
|
Which architecture is the default may depend on the version of Meson
|
|
and/or the current shell. To force a particular architecture you can
|
|
use a Meson cross-file, as follows.
|
|
|
|
To build for Apple Silicon (arm64):
|
|
|
|
```
|
|
$ meson build --cross-file cross/macos-arm64.txt && ninja -C build
|
|
```
|
|
|
|
To build for Intel (x86_64):
|
|
|
|
```
|
|
$ meson build --cross-file cross/macos-x86_64.txt && ninja -C build
|
|
```
|
|
|
|
You can build a universal binary library for both architectures like
|
|
this:
|
|
|
|
```
|
|
$ meson build --cross-file cross/macos-universal.txt && ninja -C build
|
|
```
|
|
|
|
Note that the universal cross file also sets the minimum OS version to
|
|
the earliest supported macOS versions for both architectures. (Note
|
|
that actual compatibility will also depend on how any dependent
|
|
libraries have been compiled.) You can edit this in the
|
|
`cross/macos-universal.txt` file if you want a specific target.
|
|
|
|
See "FFT and resampler selection" below for further build options.
|
|
|
|
Note that you cannot legally distribute applications using Rubber Band
|
|
in the Mac App Store, unless you have first obtained a commercial
|
|
licence for Rubber Band Library. GPL code is not permitted in the app
|
|
store. See https://breakfastquay.com/technology/license.html for
|
|
commercial terms.
|
|
|
|
|
|
### 4c. Building for iOS
|
|
|
|
Ensure the Xcode command-line tools are installed, and
|
|
|
|
```
|
|
$ meson build_ios --cross-file cross/ios.txt && ninja -C build_ios
|
|
```
|
|
|
|
The output files will be found in the `build_ios` directory.
|
|
|
|
To build for the simulator,
|
|
|
|
```
|
|
$ meson build_sim --cross-file cross/ios-simulator.txt && ninja -C build_sim
|
|
```
|
|
|
|
The output files will be found in the `build_sim` directory.
|
|
|
|
See "FFT and resampler selection" below for further build options.
|
|
|
|
Note that you cannot legally distribute applications using Rubber Band
|
|
in the iOS App Store, unless you have a first obtained a commercial
|
|
licence for Rubber Band Library. GPL code is not permitted in the app
|
|
store. See https://breakfastquay.com/technology/license.html for
|
|
commercial terms.
|
|
|
|
|
|
### 4d. Building on Windows
|
|
|
|
If you only need to build the static library for integration into your
|
|
project, and you prefer a Visual Studio project file, you can find a
|
|
simple one in `otherbuilds\rubberband-library.vcxproj`.
|
|
|
|
The rest of this section describes the "full" build system, which uses
|
|
Meson just as on the other platforms. So to build this way, start by
|
|
ensuring Meson and Ninja are installed and available. Then, in a
|
|
terminal window with the compiler tools available in the path (e.g. a
|
|
Visual Studio command-line prompt for the relevant build architecture)
|
|
run
|
|
|
|
```
|
|
> meson build
|
|
> ninja -C build
|
|
```
|
|
|
|
The output files will be found in the `build` directory.
|
|
|
|
The Rubber Band code is compatible with both the traditional Visual
|
|
C++ compiler (`cl`) and the Clang front-end (`clang`), and the build
|
|
system will use whichever appears (first) in your path.
|
|
|
|
To build against a specific Visual C++ runtime, use the built-in Meson
|
|
option `b_vscrt`:
|
|
|
|
```
|
|
> meson build -Db_vscrt=mt
|
|
```
|
|
|
|
See "FFT and resampler selection" below for further build options.
|
|
|
|
|
|
### 4e. Building for Android and Java integration
|
|
|
|
Currently only a very old Android NDK build file is provided, as
|
|
`otherbuilds/Android.mk`. This includes compile definitions for a
|
|
shared library built for ARM architectures which can be loaded from a
|
|
Java application using the Java native interface (i.e. the Android
|
|
NDK).
|
|
|
|
The Java side of the interface can be found in
|
|
`com/breakfastquay/rubberband/RubberBandStretcher.java`.
|
|
|
|
See
|
|
https://hg.sr.ht/~breakfastquay/rubberband-android-simple-sample
|
|
for a very trivial example of integration with Android Java code.
|
|
|
|
The supplied `.mk` file uses KissFFT and the Speex resampler.
|
|
|
|
|
|
### 4f. FFT and resampler selection
|
|
|
|
Rubber Band requires the selection of library code for FFT calculation
|
|
and resampling. Several libraries are supported. The selection is
|
|
controlled (in Meson) using `-D` options and (in the code itself)
|
|
using preprocessor flags set by the build system. These options and
|
|
flags are detailed in the tables below.
|
|
|
|
At least one resampler implementation and one FFT implementation must
|
|
be enabled. It is technically possible to enable more than one, but
|
|
it's confusing and not often useful.
|
|
|
|
If you are building this software using the bundled Speex or KissFFT
|
|
library code, please be sure to review the terms for those libraries
|
|
in `src/speex/COPYING` and `src/kissfft/COPYING` as applicable.
|
|
|
|
If you are proposing to package Rubber Band for a Linux distribution,
|
|
please select either the built-in FFT (simpler for you) or FFTW (a bit
|
|
faster) and use libsamplerate.
|
|
|
|
#### FFT libraries supported

|
### 4g. Other supported #defines
|
|
|
|
Other known preprocessor symbols are as follows. (Usually the supplied
|
|
build files will handle these for you.)
|
|
|
|
-DLACK_BAD_ALLOC
|
|
Define on systems lacking std::bad_alloc in the C++ library.
|
|
|
|
-DLACK_POSIX_MEMALIGN
|
|
Define on systems lacking posix_memalign.
|
|
|
|
-DUSE_OWN_ALIGNED_MALLOC
|
|
Define on systems lacking any aligned malloc implementation.
|
|
|
|
-DLACK_SINCOS
|
|
Define on systems lacking sincos().
|
|
|
|
-DNO_EXCEPTIONS
|
|

|
|
|
|
-DNO_THREADING
|
|
Build without any multithread support.
|
|
|
|
-DUSE_PTHREADS
|
|
Use the pthreads library (required unless NO_THREADING or on Windows)
|
|
|
|
-DPROCESS_SAMPLE_TYPE=float
|
|
Select single precision for internal calculations. The default is
|
|
double precision. Consider in conjunction with single-precision
|
|
KissFFT for mobile architectures with slower double-precision
|
|
support.
|
|
|
|
-DUSE_POMMIER_MATHFUN
|
|
Select the Julien Pommier implementations of trig functions for ARM
|
|
NEON or x86 SSE architectures. These are usually faster but may be
|
|
of lower precision than system implementations. Consider using this
|
|
for mobile architectures.
