High fidelity neural audio codec
Decision gist · record as of 2026-08-14
Yes, if you are conducting research on audio compression or need discrete audio codes for a non-commercial pipeline and can manage PyTorch as a dependency. No, if you need commercial licensing, active maintenance, or a lightweight codec for production systems. The noncommercial license and dormant maintenance status are the primary constraints.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires Python 3.8, PyTorch 1.11.0 or later, and external audio libraries; models auto-download via Torch Hub on first use.
- High install friction: requires Python 3.8 and PyTorch 1.11.0 or later.
- Maintenance is dormant—last release was 2022-10-25 and repository has not been updated since 2024-01-04, so expect no active bug fixes or dependency updates.

What it is and what it does
EnCodec is a neural audio compression system that encodes audio into discrete codes at very low bitrates. It provides two pre-trained models: a causal 24 kHz model for mono audio and a non-causal 48 kHz model for stereo audio, each supporting multiple target bitrates. The codec can compress to 1.5, 3, 6, 12, or 24 kbps depending on the model, and includes an optional language model that can achieve up to 40% additional compression through entropy coding.
The package is designed for research and non-commercial use. It operates as both a command-line tool for direct audio compression and decompression, and a Python API for extracting discrete audio representations. Models are automatically downloaded via Torch Hub on first use. Installation requires Python 3.8 and a recent PyTorch version, making it a heavy dependency for projects that do not already use deep learning frameworks.
Use it for
- Research on neural audio compression and discrete audio representations for machine learning.
- Compressing audio archives to very low bitrates for storage in non-commercial settings.
- Extracting discrete codes from audio for use as input to downstream models.
- Comparing audio quality at different compression levels via the command-line interface.
- Prototyping audio codec improvements using the provided MS-STFT discriminator code.
