AndroidSoundTouch
A handy SoundTouch java wrapper library for Android
This repo is a java wrapper of SoundTouch for Android.
- Keep APIs of soundtouch and provide a Java class to process audio streams so you can do it without any C/C++ code.
- Support ENCODING_PCM_16BIT samples.
- Support mono(1)/stereo(2) channels.
- Support short/byte array input/output
Demo
Note: You should grant audio record permission manually before using.
Usage
Gradle:
repositories {
jcenter()
}
// For gradle plugin 2.x
dependencies {
compile 'io.github.junyuecao:soundtouch:1.0.1'
}
// For gradle plugin 3.x
dependencies {
implementation 'io.github.junyuecao:soundtouch:1.0.1'
}The APIs are almost the same with the C/C++ version.
- in Java
public void onVoiceStart() {
mSoundTouch = new SoundTouch();
mSoundTouch.setChannels(1);
mSoundTouch.setSampleRate(VoiceRecorder.SAMPLE_RATE);
}
public void onVoice(byte[] data, int size) {
mSoundTouch.setRate(mRate);
mSoundTouch.setPitch(mPitch);
mSoundTouch.putSamples(data, size);
int bufferSize = 0
do {
bufferSize = mSoundTouch.receiveSamples(mTempBuffer, BUFFER_SIZE);
if (bufferSize > 0) {
mTestWavOutput.write(mTempBuffer, 0, bufferSize);
}
} while (bufferSize != 0);
}
public void onVoiceEnd() {
mSoundTouch.release();
}
