Android Jni interface to "ChunkWare Music Software" audio compressor/gate/limiter filters

Example:

```java

	import sa.dsp.Compressor;

	import sa.dsp.Gate;

	public void record {

		Compressor compressor = new Compressor();

		compressor.setThresh(-10.0d);

		compressor.setRatio(-4.0d);

		compressor.initRuntime();

		Gate gate = new Gate();

		gate.setThresh(-36.0d);

		gate.initRuntime();

		

		int bufferSize = AudioRecord.getMinBufferSize(RECORDER_SAMPLERATE,

					RECORDER_CHANNELS, RECORDER_AUDIO_ENCODING);

		

		AudioRecord recorder = new AudioRecord(MediaRecorder.AudioSource.MIC,

				RECORDER_SAMPLERATE, RECORDER_CHANNELS,

				RECORDER_AUDIO_ENCODING, bufferSize);

		

		recorder.startRecording();

		

		short pcm[] = new short[bufferSize];

		

		int read = 0;

		while (true) {

			read = recorder.read(pcm, 0, bufferSize);

			

			if (read > 0 && AudioRecord.ERROR_INVALID_OPERATION != read) {

				gate.process(read, pcm);

				compressor.process(read, pcm);

			}

		}

		

		recorder.stop();

		recorder.release();

	}
