Text-Driven Audio Sequencer, now with AI

SynapSeq is an open-source audio sequencer for generate binaural, monaural, isochronic, and ambient audio.

AI-assisted sequencing

From intent to SPSQ.

Describe the listening experience you want, then review a plain-text SPSQ sequence ready for your CLI workflow.

A creative flow you can revisit

Sketch an idea, shape an SPSQ session, render it, and return to the design when a new pass is useful.

  1. 01

    Imagine

    Start with a mood, duration, or texture to explore.

  2. 02

    Design

    Choose a tone, modulation option, and noise layer.

  3. 03

    Compose

    Arrange presets on a plain-text timeline.

    • Binaural beats
    • Monaural beats
    • Isochronic tones
    • Noise
    • Ambient audio
  4. 04

    Render

    Turn the sequence into an audio file.

  5. 05

    Listen

    Play it externally on headphones, a computer, or a phone.

  6. 06

    Refine

    Adjust the design and make another version whenever it helps.

Remote Sequence Library

Listen to community sequences from SynapSeq Remote, then switch between their description and SPSQ source.

Loading the remote sequence library…

Install SynapSeq

Install SynapSeq and its required audio tools with your platform package manager.

The remote script supports Debian derivatives (including Ubuntu ) and Fedora.

>_curl -fsSL https://synapseq.org/install.sh | sudo bash

Fedora requires RPM Fusion Free and Nonfree first. View the RPM Fusion configuration instructions.

From SBaGen to SynapSeq

SynapSeq began by keeping SBaGen's idea alive. Over time, preserving the idea mattered more than preserving the implementation.

“Describe the experience as text. Turn it into sound.”

  1. SBaGen

    SBaGen

    Created by Jim Peters, SBaGen established sequenced, timed audio described as text.

  2. SBaGen+

    SBaGen+

    Ruan's direct fork maintained the original engine on modern systems and added isochronic tones.

  3. New design

    SynapSeq 2.x

    SPSQ was part of the first SynapSeq release, 2.0.0. The 2.x series shifted toward a simpler, render-first architecture.

  4. New implementation

    SynapSeq 3.x

    Rewritten from scratch in Go, it no longer depended on SBaGen or SBaGen+ code.

  5. Independent engine

    SynapSeq 4.x

    The independent engine and SPSQ reached a more mature foundation.
