I am using a patch to implement a peaking filter (using biquad~) given freq/q/gain.
The patch works fine in Pd, however when using it with Android Studio, I don't get sound. No errors are shown in Android Studio, the patch loads fine, just no sound.
If I take away the section of the patch converting the f/q/g parameters into filter coefficients, and just give in 5 random coefficients, the patch works fine.
Thus, I presume the issue is with the expr object as besides that, there isn't much else extra. Is there anything specific which I would have to add to my Android Studio project due to using expr?
This patch doesn't work.
This patch does work.
My java file looks like this:
package com.example.mark.pdaudioio;
import android.support.v7.app.AppCompatActivity;

import java.io.File;
import java.io.IOException;
public class MainActivity extends AppCompatActivity {
TextView volumeTextViewJava;
SeekBar volumeSeekBarJava;
int volume = 0;
private PdUiDispatcher dispatcher;
private void initPD() throws IOException{
int sampleRate = AudioParameters.suggestSampleRate();
int inpch = AudioParameters.suggestInputChannels();
PdAudio.initAudio(sampleRate, inpch, 2, 8, true);
dispatcher = new PdUiDispatcher();
PdBase.setReceiver(dispatcher);
}
private void initGUI(){
Switch onOffSwitch = (Switch) findViewById(R.id.onOffSwitch);
onOffSwitch.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
@Override

float val = (isChecked) ? 1.0f : 0.0f;
PdBase.sendFloat("onOffPD",val);
}
});
volumeTextViewJava = (TextView) findViewById(R.id.volumeTextView);
volumeSeekBarJava = (SeekBar) findViewById(R.id.volumeSeekBar);
volumeSeekBarJava.setMax(100);
volumeSeekBarJava.incrementProgressBy(1);

volumeSeekBarJava.setOnSeekBarChangeListener(new SeekBar.OnSeekBarChangeListener() {
public void onProgressChanged(SeekBar seekBar, int volProgress, boolean fromUser) {

float volumeFloat = (float) volume;
PdBase.sendFloat("volumePD", volumeFloat);
volumeTextViewJava.setText("vol: " + volProgress);
}
public void onStartTrackingTouch(SeekBar seekBar) {
}
public void onStopTrackingTouch(SeekBar seekBar) {
}
});
}
private void loadPDPatch() throws IOException{
File dir = getFilesDir();
IoUtils.extractZipResource(getResources().openRawResource(R.raw.simplepatch),dir,true);
File pdPatch = new File(dir, "Biquad_WithExpr.pd");
PdBase.openPatch(pdPatch.getAbsolutePath());
}
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
try{
initPD();
loadPDPatch();
}catch (IOException e){
finish();
}
initGUI();
}
@Override
protected void onResume(){
super.onResume();
PdAudio.startAudio(this);
}
@Override
protected void onPause(){
super.onPause();
PdAudio.stopAudio();
}
}
Here is a link to my full Android Studio project. https://www.dropbox.com/s/aorji4heum8jvbc/PDAudioIO.zip?dl=0
Any help at all is greatly appreciated!!
