Post Processing

getPresetsNames

The method String[] VoicemodSDK.getPresetsNames() give you an array with the current voices names.

Convert methods

Given an audio or video file, the convert methods give you the possibility to generate a new file with audio modified. Indicating in the voiceName parameter any of the values returned by getPresetsNames.

VoicemodSDK.convertAudio( Uri source, String voiceName, ConvertListener handler)

// Example of convertAudio call using file from assets folder.

VoicemodSDK.convertAudio( Uri.parse("file:///android_asset/" + filename), "alien", new VoicemodSDK.ConvertListener() {

public void onCompleted(String error, Uri audioOutputPath) {

// Check possible error

if (error == null) {

// Play, send, share the audio file with path audioOutputPath

} else {

Log.d("ERROR", error);

}

});

VoicemodSDK.convertVideo( Uri source, String voiceName, ConvertListener handler)

// Example of convertVideo call using file stored on file system.

VoicemodSDK.convertVideo( Uri.parse("file:///" + filepath + "/" + filename), "alien", new VoicemodSDK.ConvertListener() {

public void onCompleted(String error, Uri videoOutputPath) {

// Check possible error

if (error == null) {

// Play, send, share the video file with path videoOutputPath

} else {

Log.d("ERROR", error);

}

});

ConvertListener handler

When the audio or video has been processed, a call will be made to the method:

1	ConvertListener.onCompleted(String error, Uri audioOutputPath)

In the audioOutputPath argument is the path where the modified file was stored.

This call is made in a thread other than UiThread, so if the action modifies the interface a call to runOnUiThread should be made.

Uri source

In the source parameter we specify the source path of the file to be modified.

Currently supported sources are:

File system files, with structure file://$FILE_PATH.
Example: file:///data/user/0/net.voicemod.android.voicemodsdkexample/files/Video_SDK.mp4
Files in the assets folder, with the structure file:///android_asset/$ASSET_PATH
Example: file:///android_asset/demo-offline.m4a

Convert supported formats

The convert supported formats are the ones specified in the next url:
https://developer.android.com/guide/topics/media/media-formats.html

For example, you can record audio with the classes of the Android SDK, as shown in this example:
https://developer.android.com/guide/topics/media/mediarecorder.html#example

For best quality conversions sample rate must be changed to 44100 or 48000.

1	mRecorder.setAudioSamplingRate(44100);

On future releases we are going to support more sample rates doing resampling.
