Deep Learning for Audio in CSharp and Keras
The packages runs in x64 and built with .NET 4.6.1. Therefore you need to
- Set the "Target framework" to ".NET Framework 4.6.1" in the Application tab of your project Properties
- Set the "Platform Target" to x64 in the Build tab of your project Properties
- Set the .NET configuration manager to x64 in Visual Studio IDE
Make sure that you have the following installed:
- TensorFlowSharp Version 1.7.0 (used to run the tensorflow audio classifier trained models)
Run the following command in your nuget manager console:
Install-Package TensorFlow-Deep-Music -Version 1.0.3
The following dlls are also installed when installing the TensorFlow-Deep-Music:
- Bass.NET Version 1.0.0 (used to convert audio file to melgram)
- System.ValueTuple Version 4.4.0 (required by TensorFlowSharp)
Below is thecode showing how to useAudioClassifierto predict the genres of an audio file:
usingSystem;usingcsharp_deep_learning_audio;usingSystem.IO;namespacecsharp_deep_learning_audio_samples{classProgram{staticvoidMain(string[]args){AudioClassifierc=newAudioClassifier();stringdataDirPath=@"C:\Users\chen0\git\csharp-deep-learning-audio\gtzan\genres";string[]subDirectories=Directory.GetDirectories(dataDirPath);foreach(stringsubDirectoryinsubDirectories){string[]files=Directory.GetFiles(subDirectory,"*.au");foreach(stringfileinfiles){Console.WriteLine("classifing: {0}",file);Console.WriteLine("predicted: {0}",c.PredictLabel(file));break;}}}}}
Below is thecode showing how to index music files and perform query to find similar songs:
usingSystem;usingcsharp_deep_learning_audio;usingSystem.IO;usingSystem.Collections.Generic;namespacecsharp_deep_learning_audio_samples{classSearchEngineDemo{publicstaticvoidDemo(){AudioSearchEnginec=newAudioSearchEngine();stringdataDirPath=Path.Combine(IOUtils.AssemblyDirectory,"..","..","..","..","gtzan","genres");string[]subDirectories=Directory.GetDirectories(dataDirPath);foreach(stringsubDirectoryinsubDirectories){string[]files=Directory.GetFiles(subDirectory,"*.au");foreach(stringfileinfiles){c.IndexAudio(file);}}inttopK=10;List<ComparableAudioEntry>result=c.Query(Path.Combine(IOUtils.AssemblyDirectory,"..","..","..","..","music-samples","example.mp3"),topK);for(inti=0;i<result.Count;++i){Console.WriteLine("#{0} (Score: {1}): {2}",i+1,result[i].Distance,result[i].AudioFile);}}}}
