Could Not Load File Or Assembly Naudio

Hi , I'm trying to play mp3 from robo head:

try
            {
                using (NAudio.Wave.Mp3FileReader mp3 = new NAudio.Wave.Mp3FileReader(filePath))
                {
                    using (NAudio.Wave.WaveFormatConversionStream pcm = new NAudio.Wave.WaveFormatConversionStream(new NAudio.Wave.WaveFormat(EZ_B.EZBv4Sound.AUDIO_SAMPLE_BITRATE, 8, 1), mp3))
                    {
                        using (MemoryStream ms = new MemoryStream())
                        {
                            using (GZipStream gz = new GZipStream(ms, CompressionMode.Compress))
                                EZBManager.EZBs[0].SoundV4.PlayData(gz);
                        }
                    }
                }
            }

NAudio was addeg with nuget package manager, but it provides error:

To play MP3 files from your EZ-InMoov Robot Head and resolve the "Could not load file or assembly NAudio" error, you can follow these steps. It seems like you're trying to create a plugin or script that utilizes NAudio for audio playback within the Synthiam ARC environment. Here's a general approach to troubleshoot and achieve playing MP3 files:

1. Ensure NAudio is Correctly Installed

First, make sure that NAudio is correctly installed in your project. Since you've mentioned using NuGet Package Manager, you can verify the installation by checking the packages.config file in your project or looking at the References list in the Solution Explorer to see if NAudio is listed.

2. Check for Assembly Binding Issues

The error "Could not load file or assembly" often indicates a version mismatch or that the assembly cannot be found. You can try the following:

  • Check the Version: Ensure that the version of NAudio you're referencing in your project matches the version expected by any code that's using it.
  • Copy Local: In the properties of the NAudio reference in your project, set "Copy Local" to True. This ensures that NAudio.dll is copied to the output directory of your project.

3. Using NAudio to Play MP3

Here's a simple example of how to use NAudio to play an MP3 file. Ensure you have NAudio installed and then use the following code snippet:

using NAudio.Wave;

public void PlayMp3File(string filename)
{
    using (var mp3Reader = new Mp3FileReader(filename))
    using (var waveOut = new WaveOutEvent()) // or WaveOut(); for older NAudio versions
    {
        waveOut.Init(mp3Reader);
        waveOut.Play();
        while (waveOut.PlaybackState == PlaybackState.Playing)
        {
            System.Threading.Thread.Sleep(100);
        }
    }
}

4. Integrating with Synthiam ARC

If you're creating a plugin for Synthiam ARC, you'll need to ensure that your plugin correctly references and packages NAudio. When you build your plugin, make sure the NAudio DLL is included in the output directory or packaged with your plugin.

5. Alternative: Using Synthiam ARC's Built-in Audio Features

Synthiam ARC has built-in support for playing audio files. If you're looking to play MP3 files as part of a robot action or behavior, you might not need to use NAudio directly. Instead, you can leverage ARC's audio playback capabilities through its scripting or graphical interface.

Troubleshooting

  • If you continue to experience issues, double-check the path to the MP3 file to ensure it's correct and accessible by your application.
  • Consider testing with a different MP3 file to rule out any issues with the specific file you're using.

By following these steps, you should be able to resolve the assembly loading issue and play MP3 files from your EZ-InMoov Robot Head using NAudio or Synthiam ARC's built-in features.

All the libraries you need for the project are located in the ARC installation folder.

it’s c:\program files (86\arc by synthiam or something like that

Oh and just make sure you mark the resource libraries to not copy as a build action
