<h1>SoundTouch in Android</h1>
<hr>
<h2>Compiling SoundTouch for Android</h2>
<p>SoundTouch source code package contains &quot;Android-lib&quot; example project that compiles SoundTouch
source codes into Android native library, and gives an example of JNI interface
for invoking
the native SoundTouch routines from an Android application written in Java.</p>
<p style="font-weight: 700">Software prerequisites:</p>
<ul>
<li>Android SDK environment for developing your own Android application. Visit the <a href="http://developer.android.com/index.html">Android developers' site</a>
for more information about the Android SDK and developing Android applications.</li>
<li>Android NDK compiler kit for compiling native library binaries. The Android NDK
is <a href="http://developer.android.com/tools/sdk/ndk/index.html">
available for download</a> at the Android developer tools site.</li>
<li>In case you're working in Windows environment, install
<a href="http://cygwin.com/install.html">
Cygwin</a> to run the Android NDK/SDK compiler scripts</li>
<li>Latest SoundTouch source code package available at <a href="http://soundtouch.surina.net/sourcecode.html">
soundtouch.surina.net</a>.</li>
</ul>
<p><b>Hint: </b>As installing and configuring all the components for an Android SDK/NDK
environment requires fair effort, it&#39;s good idea to create a dedicated Virtual
Machine environment for the Android development environment installation.
Having the Android developer environment setup in dedicated Virtual Machine
allows keeping all these settings isolated from your other PC operations, and
eases taking backup snapshots of your full development environment.</p>
<p><b>Compiling</b></p>
<p>
To compile the SoundTouch library source codes into an Android native library,
open Cygwin/bash shell, go to directory <b>&quot;soundtouch/source/Android-lib/jni&quot;</b> and invoke the NDK
compiler with following command:</p>
<pre> $NDK/ndk-build</pre>
<p>This will build binaries for all the supported Android platforms (arm-v5, arm-v7, X86, MIPS etc) of SoundTouch library, plus the JNI wrapper interface as discussed below. The target binaries will be built into the &quot;libs&quot; subdirectory. As long as all these .so binary library versions are included in the APK Application delivery package, the target Android device can choose the correct library version to use. </p>
<p>Notice that to allow Cygwin/bash to locate the NDK compile scripts, you
need to define the location of the NDK installation defined in environment
variable &quot;NDK&quot;. That's easiest done by adding the NDK path definition at end of
your <b>~/.bash_profile</b> file, for instance as follows:</p>
<pre> NDK=/cygdrive/d/Android/android-ndk-r6</pre>
<p><b>Enabling OpenMP parallel computing mode</b></p>
<p>
SoundTouch supports OpenMP for parallel computing in multi-core
environments, and these improvements can be enabled also in the Android
build. See the SoundTouch main README.html file for generic notes about the
OpenMP implementation.</p>
<p>
To enable OpenMP mode in Android compilation, edit file <strong>Android.mk</strong>
and enable the &quot;-fopenmp&quot; flag in LOCAL_CFLAGS and LOCAL_LDFLAGS variables.
This is done by removing hash # from before the following lines in the
Android.mk file, before compiling the library:</p>
<pre> LOCAL_CFLAGS += -fopenmp
LOCAL_LDFLAGS += -fopenmp</pre>
<p><strong>OpenMP COMPATIBILITY NOTE: </strong>Android NDK has a threading issue
(at least until NDK v10) that causes the native library crash with fatal signal
11 if calling OpenMP-improved routines from a background thread. SoundTouch has
a workaround for this issue in soundtouch-jni.cpp, and this workaround requires
calling function <strong>SoundTouch.getVersionString() </strong>from the Android
application's main thread at least once before calling other SoundTouch
processing routines. See the SoundTouch Android example application and comments
in the <strong>soundtouch-jni.cpp </strong>source code file for more details.</p>
<p>
<strong>SoundTouch performance in Android</strong></p>
<p>
See external blog articles for more discussion about the
<a href="http://www.softwarecoven.com/parallel-computing-in-embedded-mobile-devices/">
SoundTouch OpenMP implementation</a> and the
<a href="http://www.softwarecoven.com/parallel-computing-with-openmp-in-android/">
SoundTouch performance benchmark tests in Android environment</a>.</p>

<h2>
Calling SoundTouch native routines from Android application</h2>
<p>The NDK tools build the SoundTouch c++ routines into a native binary library, while
Android applications are written in Java language. To call the SoundTouch and other c/c++
routines from an Android java application code, you'll need to use Java Native
Interface (JNI).</p>
<p>
The SoundTouch source code package provides source code example how to
use JNI to call native c++ routines from a Java class, and provides source codes also for
a simple example Android application:<ul>
<li><b>ExampleActivity</b>: This is simple Android example application that
utilizes SoundTouch native routines for processing WAV audio files. To build the example
application, use Eclipse Android SDK environment to import the "ExampleActivity" project in the "Android-lib" folder into the Eclipse workspace.
<li><b>Android-lib/jni/soundtouch-jni.cpp</b>: This file contains c/c++ wrapper routines
for performing elementary audio file processing with adjusted tempo/pitch/speed parameters
from the Android application. The wrapper interface is not complete, but provides example
that is easy to extend when necessary. The NDK compiles this file along with the SoundTouch
routines into the native binary library.</li>
<li><b>Android-lib/src/net/surina/soundtouch/SoundTouch.java</b>: This file implements
the Java interface class that loasd & accesses the JNI routines in the natively compiled library.
The example Android application uses this class as interface for processing audio files
with SoundTouch.</li>
<li><b>Android-lib/build.gradle</b>: Top level build script file for Android Studio 3.1.4+</li>
</ul>
<p>
Feel free to examine and extend the provided cpp/java source code example file pair to
implement and integrate the desired SoundTouch library capabilities into your own Android application.</p>

<h2>
Android floating-point performance considerations</h2>
<p>
The make process will build dedicated binaries for each supported Android CPU hardware platform type.
</p><p>SoundTouch uses floating-point algorithms for ideal sound quality on all other platform than in the lowest-end ARMv5. That is because lowest-end Android devices are not guaranteed to
have floating-point hardware in their CPUs, so that the ARMv5 compilation uses by default software-emulation for floating-point calculations to allow running the binary executables also in low-end devices without floating-point hardware.<p>
As floating point software-emulation is however several tens of times slower
than real hardware-level floating-point calculations, that would make running
floating-point-intensive applications such as SoundTouch infeasible in these low-end
devices. As workaround, the SoundTouch Android compilation builds the ARMv5 version using integer algorithm versions. The integer
algorithm version compromises the sound quality but provides good performance also
with low-end devices without hardware floating-point support in the CPU level.</p>
<p>When Android devices with more capable device is used, the device will automatically choose a proper library version for ideal sound quality.</p>
