jacksharp's Introduction

Due to Github's determination to be the "world’s leading AI-powered developer platform" I will move my projects to Codeberg

Jack-Sharp

Jack-Sharp is a .NET/mono binding for Jack, and contains multiple: JackSharp, Jack.NAudio, and Jack.CSCore. The latter projects are bindings of JackSharp for NAudio and CSCore.

Tested Platforms

Debian GNU/Linux sid amd64 and i386
Windows 8.1

Dependencies

Jack
.NET >= 3.5 or Mono >= 2.4.0

JackSharp

C# Wrapper around libjack API. Uses the following classes to structure the API into manageable chunks. Abstracts away all pointers.

Install via NuGet: nuget install JackSharp.

Client: Base Class for Processor and Controller

Emits events on general Jack information, that consumers can subscribe to. See the source code comments for details.

Processor

Audio and MIDI client. Useful for creating an application with inputs and outputs.

Add your logic for processing a buffer on audio and MIDI input and output by adding a Func<JackSharp.Processing.ProcessBuffer> to ProcessFunc of an instance of JackSharp.Processor. Multiple methods can be added and removed.

Controller

Client for controlling the Jack server and connections. Useful for creating a control application.

Can connect and disconnect ports of different applications.

If your application needs functionality from both Processor and Controller, then you must create instances of both classes in your consumer with different names.

Jack.NAudio

Binding for JackSharp.Processor for NAudio. It contains implementations for IWavePlayer and IWaveIn.

Install via NuGet: nuget install Jack.NAudio.

Jack.CSCore

Binding for JackSharp.Processor for CSCore. It contains implementations for ISoundOut and ISoundIn.

Install via NuGet: nuget install Jack.CSCore.

Running Unit Tests

Running unit tests can be a bit tricky, as some unit tests require an already running instance of Jack, while others require, that Jack must be started by the tested objects themselves.

The following test class from the project JackSharpTest must be run without Jack:

jacksharp's Issues

MIDI-In not working correctly.

Bug reported via email:

Hi,

is MIDI-in working with JackSharp? I'm trying to just receive MIDI
from my controller. I receive events, but they don't contain any data.
Here is what I do:

 foreach (MidiEventCollection<MidiInEvent> eventCollection in items.MidiIn)
 {
     foreach (MidiInEvent midiEvent in eventCollection)
     {
         if (midiEvent.MidiData.Length > 0)
         {
             Console.WriteLine ("Hurray!");
         }
         Console.WriteLine( BitConverter.ToString (midiEvent.MidiData) );
     }
 }

midiEvent.MidiData is always empty (and 0 bytes long).

Rerouting audio output of some applications

I would like to reroute output of some applications to selected device. For example the output from game to headphones, output from browser to loudspeakers, etc. How I can realize that idea, and this possible with this library or not?

Process Audio

Hi, thank for this project.
My idea is get sound of the micro of my computer, distortion it and send the distortion sound to the output (Speaker).
This is my code:

        private Jack.CSCore.AudioIn _soundIn;
        private Jack.CSCore.AudioOut _soundOut;
        private JackSharp.Processor _client;
        CSCore.Streams.Effects.DmoDistortionEffect _distortionEffect;
        private CSCore.Streams.SoundInSource _source;

        private void StartProcess()
        {
            try
            {
                _client = new JackSharp.Processor("TESTING", 2, 2, 0, 0, true);
                _soundIn = new Jack.CSCore.AudioIn(_client);
                _soundIn.Initialize();
                
                
                _source = new CSCore.Streams.SoundInSource(_soundIn);
                _distortionEffect = new CSCore.Streams.Effects.DmoDistortionEffect(_source);
                _distortionEffect.Edge = 10;
                _distortionEffect.PreLowpassCutoff = 4800;

                _soundOut = new Jack.CSCore.AudioOut(_client);
                _soundOut.Initialize(_distortionEffect);

                _client.Start();
                _soundOut.Play();    
            }
            catch (Exception ex)
            {
                Console.WriteLine("Exception in StartProcess: " + ex.Message);
            }

        }

        private void StopFullDuplex()
        {
            if (_client != null)
            {
                _client.Stop();
                _client.Dispose();
            }
            if (_soundOut != null) _soundOut.Dispose();
            if (_soundIn != null) _soundIn.Dispose();
        }

These are the JAckAudio connections:

This code don't work. I don't listen the micro by the Blackwire (headphones) output.
Only listen the sound by the output if I add the event CopyInToOut to the Processor (without distortion)

JackSharpTest.Dummies.ClientReceiver receiver = new JackSharpTest.Dummies.ClientReceiver();
_client.ProcessFunc += receiver.CopyInToOutAction;

void CopyInToOut (ProcessBuffer processItems)
{     
	for (int i = 0; i < Math.Min (processItems.AudioIn.Length, processItems.AudioOut.Length); i++) {
		Array.Copy (processItems.AudioIn [i].Audio, processItems.AudioOut [i].Audio, processItems.AudioIn [i].BufferSize);
	}
	Called++;
}

How must I process the sound through CSCore for distorsion the input and send the result to the output of the 'TESTING' JackSharp.Processor?

Thanks!
