2.1. Building in Microsoft Windows

Project files for Microsoft Visual C++ 6.0 and Visual C++ .NET are -supplied with the source code package. Please notice that SoundTouch -library uses processor-specific optimizations for Pentium III and AMD -processors that require a processor pack upgrade for -the Visual Studio 6.0 to be installed in order to support these -optimizations. The processor pack upgrade can be downloaded from -Microsoft site at this URL:

-

-http://msdn.microsoft.com/vstudio/downloads/tools/ppack/default.aspx

-

If the above URL is unavailable or removed, go -to http://msdn.microsoft.com -and perform a search with keywords processor pack.

-

Visual Studio .NET supports required -instructions by default and thus doesn't require installing the -processor pack.

-

To build the binaries with Visual C++ 6.0 -compiler, either run "make-win.bat" script or open the -appropriate project files in source code directories with Visual -Studio. The final executable will appear under the "SoundTouch\bin" -directory. If using the Visual Studio IDE instead of the -make-win.bat script, directories bin and -lib have to be created manually to the SoundTouch -package root for the final executables. The make-win.bat script -creates these directories automatically. +supplied with the source code package.

-

Also other C++ compilers than Visual C++ can be -used, but project or makefiles then have to be adapted accordingly. -Performance optimizations are written in Visual C++ compatible -syntax, they may or may not be compatible with other compilers. If -using GCC (Gnu C Compiler) compiler package such as DJGPP or Cygwin, -please see next chapter for instructions.

Please notice that SoundTouch library uses processor-specific +optimizations for Pentium III and AMD processors.

If using the Visual Studio IDE +instead of the make-win.bat script, directories bin and lib may need to +be created manually to the SoundTouch package root for the final +executables. The make-win.bat script creates these directories +automatically.

2.2. Building in Gnu platforms

-

The SoundTouch library can be compiled in -practically any platform supporting GNU compiler (GCC) tools. -SoundTouch have been tested with gcc version 3.3.4., but it -shouldn't be very specific about the gcc version. Assembler-level -performance optimizations for GNU platform are currently available in -x86 platforms only, they are automatically disabled and replaced with -standard C routines in other processor platforms.

NOTE: At the time of release the SoundTouch package has been -tested -to compile in GNU/Linux platform. However, in past it's happened that -new -gcc versions aren't necessarily compatible with the assembler setttings -used in the optimized routines. If you have problems getting the -SoundTouch library compiled, try the workaround of disabling the -optimizations by editing the file "include/STTypes.h" and removing -the following definition there:

+

2.2.1 Required GNU tools 

+

Bash shell, GNU C++ compiler, libtool, autoconf and automake tools +are required for compiling the SoundTouch library. These are usually +included with the GNU/Linux distribution, but if not, install these +packages first. For example, Ubuntu Linux can acquire and install +these with the following command:

+
sudo apt-get install automake autoconf libtool build-essential
+

2.2.2 Problems with GCC compiler compatibility

+

At the release time the SoundTouch package has been tested to +compile in GNU/Linux platform. However, If you have problems getting the +SoundTouch library compiled, try disabling optimizations that are specific for +x86 processors by running ./configure script with switch

-
#define ALLOW_OPTIMIZATIONS 1
+
--enable-x86-optimizations=no
+ +Alternatively, if you don't use GNU Configure system, edit file "include/STTypes.h" +directly and remove the following definition:
+
#define SOUNDTOUCH_ALLOW_X86_OPTIMIZATIONS 1
+
+ +

2.2.3 Compiling Shared Library / DLL version

+

+ The GNU compilation does not automatically create a shared-library version of + SoundTouch (.so or .dll). If such is desired, then you can create it as follows + after running the usual compilation:

+
+
g++ -shared -static -DDLL_EXPORTS -I../../include -o SoundTouch.dll \
+     SoundTouchDLL.cpp ../SoundTouch/.libs/libSoundTouch.a
+sstrip SoundTouch.dll

3.3. About algorithms

-

SoundTouch provides three seemingly -independent effects: tempo, pitch and playback rate control. -These three controls are implemented as combination of two primary -effects, sample rate transposing and time-stretching.

-

Sample rate transposing affects -both the audio stream duration and pitch. It's implemented simply -by converting the original audio sample stream to the  desired -duration by interpolating from the original audio samples. In -SoundTouch, linear interpolation with anti-alias filtering is -used. Theoretically a higher-order interpolation provide better -result than 1st order linear interpolation, but in audio -application linear interpolation together with anti-alias -filtering performs subjectively about as well as higher-order -filtering would.

-

Time-stretching means changing -the audio stream duration without affecting it's pitch. SoundTouch -uses WSOLA-like time-stretching routines that operate in the time -domain. Compared to sample rate transposing, time-stretching is a -much heavier operation and also requires a longer processing -"window" of sound samples used by the -processing algorithm, thus increasing the algorithm input/output -latency. Typical i/o latency for the SoundTouch -time-stretch algorithm is around 100 ms.

-

Sample rate transposing and time-stretching -are then used together to produce the tempo, pitch and rate -controls:

3.4 Tuning the algorithm parameters

-

The time-stretch algorithm has few -parameters that can be tuned to optimize sound quality for -certain application. The current default parameters have been -chosen by iterative if-then analysis (read: "trial and error") -to obtain best subjective sound quality in pop/rock music -processing, but in applications processing different kind of -sound the default parameter set may result into a sub-optimal -result.

-

The time-stretch algorithm default -parameter values are set by these #defines in file "TDStretch.h":

SoundTouch in Android

+
+

Compiling SoundTouch for Android

+

SoundTouch source code package contains "Android-lib" 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.

+

Software prerequisites:

+
    +
  • Android SDK environment for developing your own Android application. Visit the Android developers' site + for more information about the Android SDK and developing Android applications.
  • +
  • Android NDK compiler kit for compiling native library binaries. The Android NDK + is + available for download at the Android developer tools site.
  • +
  • In case you're working in Windows environment, install + + Cygwin to run the Android NDK/SDK compiler scripts
  • +
  • Latest SoundTouch source code package available at + soundtouch.surina.net.
  • +
+

Hint: As installing and configuring all the components for an Android SDK/NDK + environment requires fair effort, it'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.

+

Compiling

+

+ To compile the SoundTouch library source codes into an Android native library, + open Cygwin/bash shell, go to directory "soundtouch/source/Android-lib/jni" and invoke the NDK + compiler with following command:

+
    $NDK/ndk-build
+

This will build the ARMv5 and ARMv7 versions of SoundTouch library (including + also the example JNI + interface, see below) into the "libs" subdirectory.

+

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 "NDK". That's easiest done by adding the NDK path definition at end of + your ~/.bash_profile file, for instance as follows:

+
    NDK=/cygdrive/d/Android/android-ndk-r6
+
+

+ Android floating-point performance considerations

+

+ Default build target for + Android NDK is ARMv5 CPU generation, as that works in + all ARM-based Android devices.

+ 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.

+ 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.

+ As workaround, the SoundTouch Android compilation builds two separate versions + of the library:

    +
  • 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.
  • +
  • ARMv7 version that compiles SoundTouch using hardware floating-point algorithms. + These algorithms provide ideal sound quality yet do not work in simpler CPU + models.
  • +
+

+ These two library compilations are already defined in file "jni/Application.mk" + so that these two separate library targets are automatically built under the "libs" + 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's capabilities.

+ 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.


+

+ Calling SoundTouch native routines from Android application

+

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).

+

+ 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:

    +
  • Android-lib/jni/soundtouch-jni.cpp: 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.
  • +
  • Android-lib/src/net/surina/soundtouch/SoundTouch.java: This file provides + a Java interface class to load the native library and to invoke the native routine implemented in + the file soundtouch-jni.cpp
  • +
+

+ 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.
