// Configure voice recording (smaller file size)
var voiceOutput = new WMAOutput("voice_memo.wma");
voiceOutput.Audio.Bitrate = 128;     // Good for voice
voiceOutput.Audio.SampleRate = 44100; // Standard sample rate
voiceOutput.Audio.Channels = 1;       // Mono is sufficient for voice

// Check if WMA encoder is available on the system
if (!WMAEncoderSettings.IsAvailable())
{
    Console.WriteLine("WMA encoder is not available on this system.");
    // Consider falling back to MP3 or other format
}

            ? $"Audio extracted to: {wmaOutputPath}" 
            : "Audio extraction failed.");
    }
    finally
    {
        videoEdit.Dispose();
    }
}

Applying Audio Effects During WMA Editing

The VideoEditCoreX class supports various audio effects that can be applied during the editing process:

using VisioForge.Core.Types.X.AudioEffects;

// Note: Call VisioForgeX.InitSDKAsync() once during application startup or form load
public async Task EditWmaWithEffectsAsync(
    string inputPath,
    string outputPath)
{
    var videoEdit = new VideoEditCoreX();

    try
    {
        // Add input file
        var audioFile = new AudioFileSource(inputPath);
        videoEdit.Input_AddAudioFile(audioFile, insertTime: null);

        // Apply audio effects

        // Volume amplification effect
        var amplifyEffect = new AmplifyAudioEffect(1.5); // 150% volume
        videoEdit.Audio_Effects.Add(amplifyEffect);

        // 10-band equalizer effect
        var eqLevels = new double[] 
        { 
            3.0,   // 60 Hz
            2.0,   // 170 Hz
            1.0,   // 310 Hz
            0.0,   // 600 Hz
            0.0,   // 1 kHz
            0.0,   // 3 kHz
            1.0,   // 6 kHz
            2.0,   // 12 kHz
            2.0,   // 14 kHz
            3.0    // 16 kHz
        };
        var equalizerEffect = new Equalizer10AudioEffect(eqLevels);
        videoEdit.Audio_Effects.Add(equalizerEffect);

        // Configure WMA output
        var wmaOutput = new WMAOutput(outputPath);
        wmaOutput.Audio.Bitrate = 192;
        wmaOutput.Audio.SampleRate = 48000;
        wmaOutput.Audio.Channels = 2;

        videoEdit.Output_Format = wmaOutput;

        var completionSource = new TaskCompletionSource<bool>();
        videoEdit.OnStop += (s, e) => completionSource.SetResult(e.Successful);

        videoEdit.Start();

        await completionSource.Task;
    }
    finally
    {
        videoEdit.Dispose();
    }
}

WMA Encoder Configuration

The WMAEncoderSettings class provides various configuration options for the Windows Media Audio encoder:

Available Settings

var wmaSettings = new WMAEncoderSettings
{
    // Bitrate in Kbps - supported values: 128, 192, 256, 320
    Bitrate = 192,

    // Sample rate in Hz - supported values: 44100, 48000
    SampleRate = 48000,

    // Number of channels - supported values: 1 (mono), 2 (stereo)
    Channels = 2
};

// Query supported configurations
int[] supportedBitrates = wmaSettings.GetSupportedBitrates();
// Returns: [128, 192, 256, 320]

int[] supportedSampleRates = wmaSettings.GetSupportedSampleRates();
// Returns: [44100, 48000]

int[] supportedChannels = wmaSettings.GetSupportedChannelCounts();
// Returns: [1, 2]

Quality Presets

Here are recommended presets for different use cases:

// High-quality music recording
var musicPreset = new WMAEncoderSettings
{
    Bitrate = 320,
    SampleRate = 48000,
    Channels = 2
};

// Voice recording / podcasts
var voicePreset = new WMAEncoderSettings
{
    Bitrate = 128,
    SampleRate = 44100,
    Channels = 1
};

// Balanced quality and file size
var balancedPreset = new WMAEncoderSettings
{
    Bitrate = 192,
    SampleRate = 48000,
    Channels = 2
};

Working with Audio Packets and Buffers

For advanced scenarios, you may need to work directly with audio data packets. The SDK provides mechanisms for accessing raw audio data during capturing and processing.

Processing Audio Packets

// During capture, you can monitor audio levels and packets
_videoCapture.OnAudioVUMeter += (sender, args) =>
{
    // Get audio levels for VU meter display
    double leftChannel = args.Left;
    double rightChannel = args.Right;

    // Update UI with audio levels
    UpdateVUMeter(leftChannel, rightChannel);
};

Error Handling and Best Practices

Proper Resource Management

Always ensure proper cleanup of SDK resources:

public class WmaProcessor : IDisposable
{
    private VideoCaptureCoreX _videoCapture;
    private bool _disposed = false;

    public async Task InitializeAsync()
    {
        await VisioForgeX.InitSDKAsync();
        _videoCapture = new VideoCaptureCoreX();
    }

    public void Dispose()
    {
        Dispose(true);
        GC.SuppressFinalize(this);
    }

    protected virtual void Dispose(bool disposing)
    {
        if (!_disposed)
        {
            if (disposing)
            {
                _videoCapture?.Dispose();
                VisioForgeX.DestroySDK();
            }
            _disposed = true;
        }
    }
}

Error Handling

Implement comprehensive error handling for production applications:

try
{
    await _videoCapture.StartAsync();
}
catch (Exception ex)
{
    // Log the error
    Console.WriteLine($"Failed to start recording: {ex.Message}");

    // Clean up resources
    await _videoCapture.DisposeAsync();

    // Notify user or retry
    throw;
}

Checking Encoder Availability

Before creating WMA files, verify the encoder is available:

if (!WMAEncoderSettings.IsAvailable())
{
    Console.WriteLine("WMA encoder is not available.");
    Console.WriteLine("Falling back to MP3 format...");

    // Use MP3 as alternative
    var mp3Output = new MP3Output("output.mp3");
    // ... continue with MP3 encoding
}

Cross-Platform Considerations

The WMA format and Windows Media components are primarily designed for Windows systems. When developing cross-platform applications:

• Windows: Full WMA support with all encoding options
• Linux/macOS: WMA encoding may require additional GStreamer plugins
• Mobile (Android/iOS): Consider using more universal formats like AAC or MP3

For cross-platform audio recording, consider these alternatives:

// Check platform and select appropriate format
string outputFormat = RuntimeInformation.IsOSPlatform(OSPlatform.Windows)
    ? "output.wma"
    : "output.m4a";  // AAC container for non-Windows

if (outputFormat.EndsWith(".wma"))
{
    var wmaOutput = new WMAOutput(outputFormat);
    _videoCapture.Outputs_Add(wmaOutput, true);
}
else
{
    var m4aOutput = new M4AOutput(outputFormat);
    _videoCapture.Outputs_Add(m4aOutput, true);
}
