• and more tba...

Source

The Source class in audion makes it simple to load media and start playing with it. Every visualization simply subscribes to a Source. It is common to have one Source instance powering multiple different visualizations. Here is a simple example of loading a media file and playing it.

var source = new Source();
    
// Open a file dialog to choose a media file
OpenFileDialog openFileDialog = new OpenFileDialog
{
    Filter = Audion.Source.SupportedFiles
};
        
// Load the media file into the source
if (openFileDialog.ShowDialog() == true)
{
    source.Load(openFileDialog.FileName);
}
    
source.Play();

Waveform

XAML

<audion:Waveform Name="waveform" 
                 Resolution="2048"
                 LeftBrush="LightBlue"                     
                 LeftStroke="Transparent"
                 LeftStrokeThickness="0"
                 CenterLineBrush="White"/>

Code

var _source = new Source();
waveform.Source = _source;

Timeline

XAML

<audion:Timeline Name="timeline" 
                 FontSize="12" 
                 ProgressBrush="#9900C3FF"
                 Position="{Binding TrackPosition}"
                 TickBrush="Silver"
                 TimeBrush="Silver"
                 ProgressLineBrush="White"
                 ProgressBrush="#772200EE"/>

Code

var _source = new Source();
timeline.Source = _source;

Spectrum Analyzer

XAML

<audion:SpectrumAnalyzer Name="spectrum" 
                         SpectrumScalingStrategy="Decibel"
                         FrequencyBarCount="100" 
                         FrequencyBarSpacing="2" 
                         FrequencyBarBrush="{StaticResource BarBrush}" />

Code

var _source = new Source();
spectrum.Source = _source;
