几天后,我试图用C#创建一个均衡器.
看过NAudio很多时间,但我找不到任何适用于naudio的均衡器.
现在几天之后,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?
解决方法
So is there another audio library which works with “pure” audio outside?
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.
