😇Usage:

dotnet add package DrAbc.SilkSharp

在nuget搜索DrAbc.SilkSharp

search nuget package: DrAbc.SilkSharp

//Encoding
SilkEncoder encoder = new();
//File
encoder.EncodeAsync("./rasputin.pcm", "./rasputin.silk");
//Stream
using FileStream fse = File.OpenRead("./rasputin.pcm");
using MemoryStream mse = new(await encoder.EncodeAsync(fse));

//Decoding
SilkDecoder decoder = new();
//File
decoder.DecodeAsync("./badmoonrising.silk", "./badmoonrising.pcm");
//Stream
using FileStream fsd = File.OpenRead("./badmoonrising.silk");
using MemoryStream msd = new(await decoder.DecodeAsync(fsd));

E.g: Convert other audio to pcm (NAudio)

using NAudio.Wave;

using Mp3FileReader reader = new("input.mp3");
WaveFormat pcmFormat = new(16000, 16, 1);
using WaveFormatConversionStream conversionStream = new(pcmFormat, reader);
SilkEncoder encoder = new()
{
    //Same with your music
    Rate = 16000,
    FS_API = 16000,
    //QQ and Wechat Compatibility
    Tencent = true
};
using MemoryStream silk = new(await encoder.EncodeAsync(conversionStream));

🏗Build

If you are using win-arm or other system, please build this project from source

Not guaranteed it can be compiled on all architectural systems.

Preparation

1. CMake 3.16 or above
2. Dotnet 8.0 SDK
3. git

C# code may compile on lower versions of dotnet, but I do not guarantee that it will behave like dotnet 8.0.

Steps

1. Compile the silkcodec with CMake

git clone https://github.com/DrAbcOfficial/SilkSharp
cd SilkSharp/silkcodec
mkdir build && cd build
cmake ..
make

2. Compile SilkSharp using dotnet (following the above command)

cd ../SilkSharp
dotnet publish -c Release -r osx-arm64

3. Copy libsilkcodec.so (or silkcodec.dll/libsilkcodec.dylib) and SilkSharp.dll to your project.

如果你正在使用win-arm或其他架构系统，请自行从源代码构建本项目

不保证可在所有架构系统上编译

准备

1. CMake 3.16或以上版本
2. Dotnet 8.0 SDK
3. git

C#代码可能可在dotnet更低版本上编译，但我不保证其行为与dotnet 8.0一致

步骤

1. 使用CMake编译silkcodec

git clone https://github.com/DrAbcOfficial/SilkSharp
cd SilkSharp/silkcodec
mkdir build && cd build
cmake ..
make

2. 使用dotnet编译SilkSharp (接上述命令)

cd ../SilkSharp
dotnet publish -c Release -r osx-arm64

3. 将libsilkcodec.so（或silkcodec.dll/libsilkcodec.dylib）及SilkSharp.dll拷贝至你的项目使用
