encodec.cpp

High-performance inference of Meta's Encodec deep learning based audio codec model:

• Plain C/C++ implementation without dependencies using ggml

Demo

Here is a demo of running Encodec on a single M1 MacBook Pro:

Roadmap

• [x] Support of 24Khz model
• [x] Mixed F16 / F32 precision
• [ ] 4-bit and 8-bit quantization
• [ ] Metal support
• [ ] cuBLAS support

Implementation details

• The core tensor operations are implemented in C (ggml.h / ggml.c)
• The encoder-decoder architecture and the high-level C-style API are implemented in C++ (encodec.h / encodec.cpp)
• Basic usage is demonstrated in main.cpp.

Usage

Here are the steps for the bark model.

Get the code

git clone --recurse-submodules https://github.com/PABannier/encodec.cpp.git
cd encodec.cpp

Build

In order to build encodec.cpp you must use CMake:

mkdir build
cd build
cmake ..
