How to use the library

• Insert the jar into your project dependencies :

<dependency>  <groupId>org.toile-libre.libe</groupId>  <artifactId>soundtransform</artifactId>  <version>LATEST</version> </dependency>

• Or as an android library :

<dependency>  <groupId>org.toile-libre.libe</groupId>  <artifactId>soundtransform</artifactId>  <version>LATEST</version>  <type>aar</type> </dependency>

• It also works as a gradle dependency :

repositories {

mavenCentral()
  
}

dependencies {

  compile 'org.toile-libre.libe:soundtransform:LATEST' 
}
 

• Make sure you have access to the FluentClient class in your project (try the autocompletion feature of your IDE if you have one)
• Read the following documentation about the FluentClient facility
• Have a look at the available SoundTransform classes
• Use the lib by yourself

FluentClient

The FluentClient service provider interface is a simple class to give a shortcut to all the features of the lib without walking in the nested classes.

It helps you to proceed to the correct actions at each step, giving you the right programming interface during the pipeline.

To use it, it is only needed to chain the methods invocation. it will always start with a FluentClient.start(), can end with a stop method and can contain an andAfterStart call to chain two processes in the same instruction of code.

FluentClient samples

import static org.toilelibre.libe.soundtransform.actions.fluent.FluentClient.start; import static org.toilelibre.libe.soundtransform.actions.fluent.FluentClient.setDefaultObservers; import static org.toilelibre.libe.soundtransform.actions.fluent.FluentClientOperation.prepare;  //...  public void method (){

//Set the default Slf4J logger and the log threshold as "WARNING" (the only output will be the warning and error logs)
setDefaultObservers (new Slf4jObserver (LogLevel.WARN));

 //Apply a 8-bit transform on a wav and then export it to a wav
start ().withClasspathResource ("foo.wav").convertIntoSound ().apply (new EightBitsSoundTransform (25)).exportToClasspathResource ("bar.wav");

 //Create a var to use the CD format
FormatInfo cdFormatInfo = new FormatInfo (2, 44100.0);

 //Shape a wav with an instrument and then export it to a wav
start ().withAPack ("default", packInputStream).withClasspathResource ("foo.wav").convertIntoSound ().findLoudestFrequencies ().shapeIntoSound ("default", "simple_piano", cdFormatInfo).exportToClasspathResource ("bar.wav");

 //Play three times the same data, as a File, then as a sound, then as an inputStream
start ().withClasspathResource ("foo.wav").playIt ().convertIntoSound ().playIt ().exportToStream ().playIt ();

  //Transform a sound into a an array of spectrums
start ().withSound (sound).splitIntoSpectrums ().stopWithSpectrums ();

 //Transform a lowfi wav file into a cd format wavfile
start ().withClasspathResource ("lowfi.wav").convertIntoSound ().changeFormat (cdFormatInfo).exportToClasspathResource ("hifi.wav");

 //Mix of two sounds using two threads for the file-to-sound conversion
start ().inParallel (
  // operations
  prepare ().convertIntoSound ().build (),
  // timeout in seconds
  5,
  // classpath resources
  "foo.wav", "bar.wav")

  .mixAllInOneSound ().exportToClasspathResourceWithSiblingResource ("targetResource.wav", "existingSoundInSameDirectory.wav");
 
}

Please have a look at the many different actions that you can ask to the FluentClient in this JUnit Test

Android ? Pure Java ? Same code ?

It would be a great thing but unfortunately the Android SDK is made to be incompatible with the Java SDK. Because a lot of security features and facilities were (and are being) implemented to protect the users in Android, whereas the Java SDK is using the OS kernel features.

For example, you cannot read a resource on an Android device. Because it is considered as a security breach by the Android SDK.

It is preventing anyone from opening any file to steal data without a consent (a permission).

The soundtransform lib needs to adapt to these two contexts (Pure Java lib / android lib) to be able to proceed data in the same way. Only input and output processing are different as described below.

The Pure Java sample will be shown first because it is simpler.

Pack import

With Pure Java, you do :

 FluentClient.start ().withAPack ("default", Thread.currentThread ().getContextClassLoader ().getResourceAsStream ("yourpack.json"))

With Android, you do :

 FluentClient.start ().withAPack ("default", androidContext, yourpackage.R.raw.class, yourpackage.R.raw.yourpack)

Open a sound input

With Pure Java, you do :

 FluentClient.start ().withFile (new File ("/path/to/file.wav")).convertIntoSound ()

With Android, you do (with the android.permission.READ_EXTERNAL_STORAGE permission) :

 FluentClient.start ().withFile (new File (Environment.getExternalStorageDirectory ().getPath () + "/file.wav")).convertIntoSound ()

Save a sound output

With Pure Java, you do :

 //...  fluentClientWithSoundImported.exportToFile (new File ("/path/to/file.wav"));

With Android, you do (with the android.permission.WRITE_EXTERNAL_STORAGE permission):

 //...  fluentClientWithSoundImported.exportToFile (new File (Environment.getExternalStorageDirectory () + "/file.wav"));

FluentClient Javadoc

Four steps can be identified when using the FluentClient SPI :

1. static init (optional) : the observers subscribe to the future invocations of the FluentClient
2. start of the flow : a call to start (), followed by one or more calls to a with... () method
3. operations (optional) : several chained method calls to transform the data in a "one-lined" way
4. method flow stops (optional) : one call to stopWith... () to get the currently stored data

1. static init

FluentClient.setDefaultObserversValue

static void setDefaultObserversValue (Observer... defaultObservers)

Sets the passed observers as the default value when a FluentClient is started

It can be useful if you are going to use the FluentClient several times but you want to declare the subscribed observers only once

2. start of the flow

FluentClient.start ( only way to start a FluentClient)

static FluentClientReady start ()

Startup the client

Returns:
the client, ready to start

FluentClientReady.withAnObserver (before another with.. method)

FluentClientReady withAnObserver (Observer... observers)

Tells the client to add an observer that will be notified of different kind of updates from the library. It is ok to call withAnObserver several times. If the andAfterStart method is called, the subscribed observers are removed

observers - one or more observer (s)

Returns:
the client, ready to start
