# Pink Trombone

[![Pink Trombone on NuGet](https://img.shields.io/nuget/v/PinkTrombone)](https://www.nuget.org/packages/PinkTrombone/)

This is a revised version of the Pink Trombone speech

synthesizer originally developed by Neil Thapen in 2017.

The original source code was modularized and converted to TypeScript.

Then the TypeScript code was converted to C#.

Pink Trombone uses two-dimensional

[digital waveguide synthesis](https://en.wikipedia.org/wiki/Digital_waveguide_synthesis)

to synthesize human speech sounds.

**Online demo**: [chdh.github.io/pink-trombone-mod](https://chdh.github.io/pink-trombone-mod)

# Sample code

You can easily connect Pink Trombone to any audio framework, that accepts

`float32` inputs. [An example](play) for [NAudio](https://github.com/naudio/NAudio):

```csharp

public sealed class PinkTromboneSampleProvider : ISampleProvider {

    public WaveFormat WaveFormat { get; }

    readonly PinkThrombone pinkThrombone;

    public PinkTromboneSampleProvider(int sampleRate) {

        this.WaveFormat = WaveFormat.CreateIeeeFloatWaveFormat(sampleRate, 1);

        this.pinkThrombone = new PinkThrombone(sampleRate);

    }

    public int Read(float[] buffer, int offset, int count) {

        this.pinkThrombone.Synthesize(buffer.AsSpan().Slice(offset, count));

        return count;

    }

}

var player = new WaveOutEvent {

    NumberOfBuffers = 2,

    DesiredLatency = 100,

};

var trombone = new PinkTromboneSampleProvider(sampleRate: 48000);

player.Init(trombone);

player.Play();

Console.WriteLine("Press any key to stop");

Console.ReadKey();

player.Stop();

```

# .NET Framework 4

This package can be retrofitted to .NET 4/.NET Standard 1.x by replacing all `float`s

with `double`s and `MathF` references with `Math`.
