encodec.cpp

A C++ implementation of Meta's Encodec using Eigen.

API

encodec::encoder enc;
encodec::decoder dec;

float audio[24000];
size_t bps = 24000; // 12000, 6000 or 3000
std::span<const uint8_t> packet = enc.encode(audio, bps);
std::span<const float>   audio2 = dec.decode(packet, bps);

Notes

• The weights are compiled into the library using the fantastic incbin library.

• You must manually implement streaming for now. Partition your audio into 1s chunks with 10ms overlap. For decoding, use a linear weighting in the overlap regions.

Features

• Block based API
• Streaming API
