# CSCodec - .NET Standard Audio Codec Development Library #

CSCodec is an open-source Audio Codec development library that has many features supporting development of your decoder and/or encoder for both your original or well-known formats.

### Currently Implemented Features: ###

- **Core Project is LICENSED UNDER __[Apache-2.0](https://github.com/MineCake147E/CSCodec/blob/master/LICENSE.md)__**

- A lot of `Span` Based APIs

- 24Bit Signed Integer Structure `Int24`

- An original **Fast Fourier Transform (FFT) IMPLEMENTATION** for `System.Numerics.Complex` arrays.

- A Discrete Cosine Transform (DCT) Type-IV for `double` and `float` based on FFT

- Wavelet Transform(Haar and CDF 5/3 Wavelets for now) for some types(`double`, `float`, `int`, `Int24`, `short`, `sbyte`)

- A Time-Domain Aliasing Cancellation (like in MDCT) support for some types(`double`, `float`)

- Hardware-Accelerated Add, Subtract, and Scalar Multiply for Arrays using `System.Numerics.Vector`

- Bit Encoded Binary Data I/O

  - BitReader and BitWriter supports I/O of bit encoded binary data

- Cyclic Redundancy Check(CRC) of 8bits, 16bits, 32bits Support(Tested with some polynomials)

- Linear Prediction support for `double` and `float` using FFT when possible and appropriate

### Features Under Development: ###

- Unit Tests for existing APIs

- Better Documentations for existing APIs

### Planned Features: ###

- Linear Prediction support for `int` and `long` in order to implement FLAC Encoder and Decoder

- Binary Compression

  - Rice Coding

  - Huffman Coding

  - Arithmetic Coding without patents

    - Range Coder

- New type `SingleComplex` that supports `float` based Complex calculation

  - FFT for `SingleComplex`

- `Parallel`ization for existing apis where possible and appropriate

- Unrounded Irreversible CDF 9/7 wavelet transform for `double`, `float`

- Rounded CDF 9/7 wavelet transform for `int`, `Int24`, `short`, and `sbyte` if possible and needed

- ID3 Tags Support

### Project Goals: ###

- .NET Standard/Core/Frameworks, Mono, and **Xamarin** Support

- Inter-operation with [MonoAudio](https://github.com/MineCake147E/MonoAudio)(*this part will be licensed under Ms-PL*)

- Inter-operation with [CSCore](https://github.com/filoe/cscore), [NAudio](https://github.com/naudio/NAudio), [MonoGame](https://github.com/MonoGame/MonoGame), etc...(*these parts will be licensed under Ms-PL*)

- Reference Implementations of cross-platform FLAC Decoder and **Encoder** for both Samples and Uses.
