Introduction

Codec-SUPERB sets a new benchmark in evaluating sound codec models, providing a rigorous and transparent framework for assessing performance across a range of speech processing tasks. Our goal is to foster innovation and set new standards in audio quality and processing efficiency.

Key Features

Out-of-the-Box Codec Interface

Codec-SUPERB offers an intuitive, out-of-the-box codec interface that allows for easy integration and testing of various codec models, facilitating quick iterations and experiments.

Multi-Perspective Leaderboard

Codec-SUPERB's unique blend of multi-perspective evaluation and an online leaderboard drives innovation in sound codec research by providing a comprehensive assessment and fostering competitive transparency among developers.

Standardized Environment

We ensure a standardized testing environment to guarantee fair and consistent comparison across all models. This uniformity brings reliability to benchmark results, making them universally interpretable.

Unified Datasets

We provide a collection of unified datasets, curated to test a wide range of speech processing scenarios. This ensures that models are evaluated under diverse conditions, reflecting real-world applications.

Installation

git clone https://github.com/voidful/Codec-SUPERB.git
cd Codec-SUPERB
pip install -r requirements.txt

Usage

Leaderboard

Out of the Box Codec Interface

from SoundCodec import codec
import torchaudio

# get all available codec
print(codec.list_codec())
# load codec by name, use encodec as example
encodec_24k_6bps = codec.load_codec('encodec_24k_6bps')

# load audio
waveform, sample_rate = torchaudio.load('sample audio')
resampled_waveform = waveform.numpy()[-1]
data_item = {'audio': {'array': resampled_waveform,
                       'sampling_rate': sample_rate}}

# extract unit
sound_unit = encodec_24k_6bps.extract_unit(data_item).unit

# sound synthesis
decoded_waveform = encodec_24k_6bps.synth(sound_unit, local_save=False)['audio']['array']
