SilkSharp

SilkSharp is a simple bundle of silk-codec https://github.com/foyoux/silk-codec

It converts audio in s16le format to and from silk v3 format.

Compatible with WeChat and QQ formats

Currently only win-x86 win-x64 linux-x86 linux-x64 linux-arm linux-arm64 osx-arm64 binary lib are available.

SilkSharp 是一个 silk-codec https://github.com/foyoux/silk-codec 的简单绑定

它实现s16le格式的音频与silk v3格式的相互转换

兼容微信和QQ格式

目前仅提供win-x86 win-x64 linux-x86 linux-x64 linux-arm linux-arm64 osx-arm64版本的二进制文件

😇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

CMake 3.16 or above
Dotnet 8.0 SDK
git

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

Steps

Compile the silkcodec with CMake

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

Compile SilkSharp using dotnet (following the above command)

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

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

CMake 3.16或以上版本
Dotnet 8.0 SDK
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

使用CMake编译silkcodec

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

使用dotnet编译SilkSharp (接上述命令)

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

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