Audigy Channels

[music.columbia.edu - JSyn mailing list]

Hi

Is it possible to output to any other lineout channels of the Audigy soundcard other than the front 2?

Regards
James

Hello,

For multi-channel devices, you can create a ChannelOut(index) instead of
a LineOut.

http://www.softsynth.com/jsyn/docs/autodocs/com/softsynth/jsyn/ChannelOut.html

You can query the channels an audio device has using AudioDevice:

Hi

I have tried a number of different routes, is it something specific to ASIO or the WMME dll's? I have been using the ChannelOut for some time.

Here something I wrote to test it :

import java.io.IOException;

import javax.sound.sampled.UnsupportedAudioFileException;

import org.apache.log4j.Logger;
import org.apache.log4j.PropertyConfigurator;

import com.softsynth.jsyn.AudioDevice;
import com.softsynth.jsyn.ChannelOut;
import com.softsynth.jsyn.SineOscillator;
import com.softsynth.jsyn.Synth;
import com.softsynth.jsyn.SynthContext;

public class Engine implements Runnable
{
  private Logger logger = Logger.getLogger(getClass());

  private SynthContext context;

  // Global server running flag
  private boolean synth_engine_running = false;

  protected SynthContext getSynthContext()
  {
    return context;
  }

  /**
   *
   */
  public void run()
  {
    PropertyConfigurator.configure("logger.properties");

    initialize();

    while (synth_engine_running)
    {
      serverWait();
    }
  }

  /**
   * Wait for activity on the server.
   */
  private synchronized void serverWait()
  {
    try
    {
      wait();
    } catch (InterruptedException e)
    {
      logger.debug("Thread Interupted : " + e.getMessage());
    }
  }

  /**
   * Initialize the audio device configured.
   */
  private void initialize()
  {
    logger.info(Synth.getVersion());

    context = new SynthContext();
    context.setTrace(Synth.TERSE);

    // Output the devices for configuration purposes.
    printDevices();

    // The context must be initialized otherwise the VM crashes.
    context.initialize();
   
    // Start the context instance, if successful flag the server as running.
    context.start(Synth.FLAG_ENABLE_INPUT, 192000, AudioDevice.getDefaultInputDeviceID(), 1, AudioDevice
        .getDefaultOutputDeviceID(), AudioDevice.getMaxOutputChannels(AudioDevice.getDefaultOutputDeviceID()));
    //    
    synth_engine_running = true;
  }

  public boolean isEngineRunning()
  {
    return synth_engine_running;
  }

  /**
   * Output a list of devices available on this system.
   */
  private void printDevices()
  {
    for (int i = 0; i < AudioDevice.getNumDevices(); i++)
    {
      logger.info(i + " : " + AudioDevice.getName(i) + " / Input=" + AudioDevice.getMaxInputChannels(i) + " / Output="
          + AudioDevice.getMaxOutputChannels(i));
    }
  }

  public static void main(String[] args) throws UnsupportedAudioFileException, IOException, InterruptedException
  {
    int tick;
    Engine engine = new Engine();

    Thread engine_thread = new Thread(engine, "Audio Engine Thread");
    engine_thread.start();

    while (!engine.isEngineRunning())
    {
      Thread.sleep(100);
    }

    ChannelOut out = new ChannelOut(engine.getSynthContext(), 3);
    SineOscillator sine = new SineOscillator(engine.getSynthContext());

    tick = engine.getTickStartTime_100ms();

    sine.output.connect(out.input);

    sine.frequency.set(1000);

    out.start(tick);
    sine.start(tick);
  }

  public int getTickStartTime_100ms()
  {
    return (int) (context.getTickCount() + (0.1d * context.getTickRate()));
  }
}

It plays fine on the first 2 channels after that it doesn't play. I have tried this on a normal PCI Audigy card and a USB Sound Blaster Audigy 2 NX

192000 Hz sample rate! Wow. Do you get the same channel result at 44100 Hz?

For multi-channel (N>2) output, you may need the ASIO version of the
DLL. WMME does not have good support for multi-channel devices. The ASIO
DLL is available to registered developers here:

Hi Phil

I get the same result with 44100Hz, at the time I was experimenting with quite a few combinations.

I am able to get it right with the ASIO version of the DLL the problem is that it seems to lock up the sound card to the degree that I cant use it with any other app. On some systems it locks up permanently after that until the next reboot.

The problem here is that there is another app that needs to output audio. This is why I wanted to use the WMME.

Do you have a suggestion?

James

Hello James,

There is a known problem with ASIO drivers that they will hang if not
shut down gracefully.

It is very important that your app call:

   Synth.stopEngine();

or

  synthContext.stopEngine();
  synthContext.delete();

when it exits if using ASIO.

Thank you,
Phil Burk

Hi Phil

Thanks, thats a good thing to know.

So it wont be possible to use the same sound card while the ASIO engine is running?
