<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 the ARMv5 and ARMv7 versions of SoundTouch library (including
also the example JNI
interface, see below) into the &quot;libs&quot; subdirectory.</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>
<hr />
<h2>
Android floating-point performance considerations</h2>
<p>
Default build target for
Android NDK is ARMv5 CPU generation, as that works in
all ARM-based Android devices.<p>
This has a pitfall though: For ideal sound quality SoundTouch should be compiled
to use floating-point algorithms, however, all low-end Android devices do not
have floating-point hardware in their CPUs, and hence the default ARMv5 compilation uses software-emulation for floating-point calculations instead of
hardware floating-point to allow running the binary executables also in low-end devices.<p>
The floating point software-emulation is however several tens of times slower
than real hardware-level floating-point calculations, making
floating-point-intensive applications such as SoundTouch infeasible with low-end
devices.<p>
As workaround, the SoundTouch Android compilation builds two separate versions
of the library:<ul>
<li>ARMv5 version that compiles SoundTouch using integer algorithm version. 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.</li>
<li>ARMv7 version that compiles SoundTouch using hardware floating-point algorithms.
These algorithms provide ideal sound quality yet do not work in simpler CPU
models.</li>
</ul>
<p>
These two library compilations are already defined in file &quot;<b>jni/Application.mk</b>&quot;
so that these two separate library targets are automatically built under the &quot;<b>libs</b>&quot;
directory. As far as you include both these compiled library versions into your
application delivery, the Android devices can automatically select the right
library version based on the available device&#39;s capabilities.<p>
Please yet be aware that depending on capabilities of the Android devices you
will need to provide the SoundTouch routines with samples in either integer or
floating-point format, so build your interface routines to take this into
account.<hr />
<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 through the following
source code file pair:<ul>
<li><b>Android-lib/jni/soundtouch-jni.cpp</b>: This file contains c/c++ routine that
calls SoundTouch library routine to return the library version string to the main
Android application. 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 provides
a Java interface class to load the native library and to invoke the native routine implemented in
the file <b>soundtouch-jni.cpp</b></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 Android application.</p>

///
/// Beats-per-minute (BPM) detection routine.
///
/// The beat detection algorithm works as follows:
/// - Use function 'inputSamples' to input a chunks of samples to the class for
/// analysis. It's a good idea to enter a large sound file or stream in smallish
/// chunks of around few kilosamples in order not to extinguish too much RAM memory.
/// - Inputted sound data is decimated to approx 500 Hz to reduce calculation burden,
/// which is basically ok as low (bass) frequencies mostly determine the beat rate.
/// Simple averaging is used for anti-alias filtering because the resulting signal
/// quality isn't of that high importance.
/// - Decimated sound data is enveloped, i.e. the amplitude shape is detected by
/// taking absolute value that's smoothed by sliding average. Signal levels that
/// are below a couple of times the general RMS amplitude level are cut away to
/// leave only notable peaks there.
/// - Repeating sound patterns (e.g. beats) are detected by calculating short-term
/// autocorrelation function of the enveloped signal.
/// - After whole sound data file has been analyzed as above, the bpm level is
/// detected by function 'getBpm' that finds the highest peak of the autocorrelation
/// function, calculates it's precise location and converts this reading to bpm's.

////////////////////////////////////////////////////////////////////////////////
///
/// Beats-per-minute (BPM) detection routine.
///
/// The beat detection algorithm works as follows:
/// - Use function 'inputSamples' to input a chunks of samples to the class for
/// analysis. It's a good idea to enter a large sound file or stream in smallish
/// chunks of around few kilosamples in order not to extinguish too much RAM memory.
/// - Inputted sound data is decimated to approx 500 Hz to reduce calculation burden,
/// which is basically ok as low (bass) frequencies mostly determine the beat rate.
/// Simple averaging is used for anti-alias filtering because the resulting signal
/// quality isn't of that high importance.
/// - Decimated sound data is enveloped, i.e. the amplitude shape is detected by
/// taking absolute value that's smoothed by sliding average. Signal levels that
/// are below a couple of times the general RMS amplitude level are cut away to
/// leave only notable peaks there.
/// - Repeating sound patterns (e.g. beats) are detected by calculating short-term
/// autocorrelation function of the enveloped signal.
/// - After whole sound data file has been analyzed as above, the bpm level is
/// detected by function 'getBpm' that finds the highest peak of the autocorrelation
/// function, calculates it's precise location and converts this reading to bpm's.
