Will likely rely on https://github.com/aaru-dps/Aaru/issues/353

Potential solution is using CSCore's WAV output.

OpticalDiscBase.cs:

/// <summary>
/// Extract a track to WAV
/// </summary>
/// <param name="trackNumber">Track number to extract</param>
/// <param name="outputDirectory">Output path to write data to</param
public abstract void ExtractTrackToWav(uint trackNumber, string outputDirectory);

/// <summary>
/// Extract all tracks to WAV
/// </summary>
/// <param name="outputDirectory">Output path to write data to</param
public abstract void ExtractAllTracksToWav(string outputDirectory);

CompactDisc.cs:

/// <inheritdoc/>
public override void ExtractTrackToWav(uint trackNumber, string outputDirectory)
{
	if(_image == null)
		return;

	// Get the track with that value, if possible
	Track track = _image.Tracks.FirstOrDefault(t => t.TrackSequence == trackNumber);

	// If the track isn't valid, we can't do anything
	if(track == null || track.TrackType != TrackType.Audio)
		return;

	// Read in the track data to a buffer
	uint length = (uint)(track.TrackEndSector - track.TrackStartSector);
	byte[] buffer = _image.ReadSectors(track.TrackStartSector, length);

	// Build the WAV output
	string filename = Path.Combine(outputDirectory, $"Track {trackNumber.ToString().PadLeft(2, '0')}.wav");
	using(WaveWriter waveWriter = new WaveWriter(filename, new CSCore.WaveFormat()))
	{
		// Write out to the file
		waveWriter.Write(buffer, 0, buffer.Length);
	}
}

/// <inheritdoc/>
public override void ExtractAllTracksToWav(string outputDirectory)
{
	if(_image == null)
		return;

	foreach(Track track in _image.Tracks)
	{
		ExtractTrackToWav(track.TrackSequence, outputDirectory);
	}
}

Player.cs:

/// <param name="trackNumber"></param>
/// <param name="outputDirectory">Output path to write data to</param
public void ExtractSingleTrackToWav(uint trackNumber, string outputDirectory) => _opticalDisc?.ExtractTrackToWav(trackNumber, outputDirectory);

/// <summary>
/// Extract all tracks from the image to WAV
/// </summary>
/// <param name="outputDirectory">Output path to write data to</param
public void ExtractAllTracksToWav(string outputDirectory) => _opticalDisc?.ExtractAllTracksToWav(outputDirectory);

public void ExtractAllTracksToWav(string outputDirectory) => _player?.ExtractAllTracksToWav(outputDirectory);

MainViewModel.cs:ExecuteKeyPress (change to async):

// Save track(s)
else if (e.Key == App.Settings.SaveTrackKey)

	if(PlayerView?.ViewModel == null)

		PlayerView.ViewModel.ExtractAllTracksToWav(path);
	else
		PlayerView.ViewModel.ExtractSingleTrackToWav((uint)PlayerView.ViewModel.CurrentTrackNumber, path);
}

SettingsViewModel.cs (after LoadImageKey):

public Key SaveTrackKey { get; set; } = Key.S;
