带均衡器的声音

几天后，我正在尝试使用C＃创建均衡器。 看过NAudio相当多的时间，但我找不到任何适用于naudio的均衡器。 现在几天后，我终于在@stackoverflow，希望你知道一种使用c＃创建均衡器的方法。

PS：我也尝试过System.Media.SoundPlayer。 但SoundPlayer甚至不支持任何与dsp有关的东西。 那么还有另一个音频库可以在外面使用“纯”音频吗？

是的，有一个： https ： //cscore.codeplex.com

根据EqualizerSample ，你可以像这样使用均衡器：

using CSCore; using CSCore.Codecs; using CSCore.SoundOut; using CSCore.Streams; using System; using System.Threading; ... private static void Main(string[] args) { const string filename = @"C:\Temp\test.mp3"; EventWaitHandle waitHandle = new AutoResetEvent(false); try { //create a source which provides audio data using(var source = CodecFactory.Instance.GetCodec(filename)) { //create the equalizer. //You can create a custom eq with any bands you want, or you can just use the default 10 band eq. Equalizer equalizer = Equalizer.Create10BandEqualizer(source); //create a soundout to play the source ISoundOut soundOut; if(WasapiOut.IsSupportedOnCurrentPlatform) { soundOut = new WasapiOut(); } else { soundOut = new DirectSoundOut(); } soundOut.Stopped += (s, e) => waitHandle.Set(); IWaveSource finalSource = equalizer.ToWaveSource(16); //since the equalizer is a samplesource, you have to convert it to a raw wavesource soundOut.Initialize(finalSource); //initialize the soundOut with the previously created finalSource soundOut.Play(); /* * You can change the filter configuration of the equalizer at any time. */ equalizer.SampleFilters[0].SetGain(20); //eq set the gain of the first filter to 20dB (if needed, you can set the gain value for each channel of the source individually) //wait until the playback finished //of course that is optional waitHandle.WaitOne(); //remember to dispose and the soundout and the source soundOut.Dispose(); } } catch(NotSupportedException ex) { Console.WriteLine("Fileformat not supported: " + ex.Message); } catch(Exception ex) { Console.WriteLine("Unexpected exception: " + ex.Message); } } 

您可以将均衡器配置为您想要的。 由于它实时运行100％，因此所有更改都会立即应用。 如果需要，还可以单独访问修改每个通道。
