SynthAX: A Fast Modular Synthesizer in JAX

SynthAX: A Fast Modular Synthesizer in JAX ⚡️

Accelerating audio synthesis far beyond realtime speeds has a significant role to play in advancing intelligent audio production techniques. SynthAX is a fast virtual modular synthesizer written in JAX. At its peak, SynthAX generates audio over 90,000 times faster than realtime, and significantly faster than the state-of-the-art in accelerated sound synthesis. It leverages massive vectorization and high-throughput accelerators. You can get started here

Basic synthax API Usage

import jax
from synthax.config import SynthConfig
from synthax.synth import ParametricSynth

# Instantiate config
config = SynthConfig(
    batch_size=16,
    sample_rate=44100,
    buffer_size_seconds=4.0
)

# Instantiate synthesizer
synth = ParametricSynth(
    config=config,
    sine=1,
    square_saw=1,
    fm_sine=1,
    fm_square_saw=0
)

# Initialize and run
key = jax.random.PRNGKey(42)
params = synth.init(key)
audio = jax.jit(synth.apply)(params)

Installation

The latest synthax release can directly be installed from PyPI:
