an pcm resample library for Android based on hutm/JSSRC
安卓上pcm数据重新采样的库 如果是wav文件舍弃前44个字节之后 就是pcm数据
File file = new File(getExternalFilesDir(null), "50waystosaygoodbye.pcm");
//重新采样后生成的文件路径
File targetWaveFile = new File(getExternalFilesDir(null), "50waystosaygoodbye_8.pcm");
//源文件的采样率、通道数、采样位数
PcmResample.AudioFileConfig srcFileConfig = new PcmResample.AudioFileConfig(file.getAbsolutePath(), 44100, AudioFormat.CHANNEL_IN_STEREO, AudioFormat.ENCODING_PCM_16BIT);
//生成文件的采样率、通道数(必须和源文件一样)、采样位数（必须和源文件一样）
PcmResample.AudioFileConfig targetFileConfig = new PcmResample.AudioFileConfig(targetWaveFile.getAbsolutePath(), 8000, AudioFormat.CHANNEL_IN_STEREO, AudioFormat.ENCODING_PCM_16BIT);
//开始重新采样 采样回调在工作线程 非UI线程
PcmResample.resample(srcFileConfig, targetFileConfig, reSampleListener);
- Add it in your root build.gradle at the end of repositories:
allprojects {
repositories {
...
maven { url 'https://jitpack.io' }
}
}
- Add the dependency
dependencies {
implementation 'com.github.ideastudios:AndroidPcmResample:v1.1.1'
}
