Introduction
Garbe.Sound is a small .NET library for audio processing. The principal idea is to give programmers with a RAD environment for developing audio filters. With the basic classes, it comes with a few filters already implemented, like:
- Gain Filter
- Delay Filter
- LowPass Filter
- Mixer
- Reverberation
- Head Related Transfer Function (HRTF)
- Read and Write Wave Files (just mono yet)
The library is still a Beta 1 Version, but is already functional. Any comments are welcome!! :)
Using the code
One of the ideias of the library is to be easy of programming. Trying to do so, I choose a sistematic view of the classes in the library, where each filter can be perceived like a box with a input and output signal.
Almost all classes in the library inheritance from SoundObj class, that implements this basic sistematic view. This permits that you write code like this:
WaveReader wr1 = new WaveReader("teste2.wav");
WaveReader wr2 = new WaveReader("teste.wav");
Gain ga1 = new Gain(0.5f);
Gain ga2 = new Gain(0.5f);
Mixer mx = new Mixer(2);
WaveWriter wwl = new WaveWriter("exit.wav", wr1.NumChannels,
wr1.SampleRate, wr1.BitsPerSamples, 1, true);
ga1.Input = wr1;
ga2.Input = wr2;
mx[0] = ga1;
mx[1] = ga2;
wwl.Input = mx;
for(int k = 0; k < wwl.Interations; k++)
{
wr1.DoProcess();
wr2.DoProcess();
ga1.DoProcess();
ga2.DoProcess();
mx.DoProcess();
wwl.DoProcess();
}
wr1.Close();
wr2.Close();
wwl.Close();
This is a very simple code that just have 2 signal inputs (teste.wav and teste2.wav), amplify both by 0.5 (ga1 and ga2 objects), mixes both in just one signal that is the output of the signal, wich is saved as exit.wav.
