A local AI audio studio for music, speech, editing, and automation.
Demodokos Foundry is a Windows desktop app that lets you generate music and speech, separate stems, patch sections, mix on a timeline, and export finished audio - all on your own machine.
Describe a song, a voice-over, or a narration. Foundry generates complete audio with vocals, instruments, or spoken word, ready in seconds, entirely on your machine.
Generate music or speech from one prompt
Caption Builder
Type what you imagine — music or speech. Adjust mood, tempo, voice style, press Generate. A full track or spoken read, done in seconds.
Audiobooks & Podcasts
Turn scripts, chapters, and show segments into polished spoken audio. Multi-speaker scenes with distinct voices, emotional direction, and 15× real-time generation speed.
Turn scripts into multi-speaker narration
Script to Speech
Assign voices to roles, steer emotion per line, and produce full audiobook chapters or podcast episodes without a recording session.
Voice & Music, One Timeline
Layer narration over original scores, blend dialogue with sound design, and mix spoken word with music beds — all in the same editor. Build trailers, immersive stories, and rich audio productions without switching apps.
Layer voice, music, and effects on one timeline
Unified Timeline
Drag voice, music, and effects onto the same visual tracks. The spectrum analyzer identifies BPM, time signature, and key. Mix everything, then export your finished production.
Whisper
Joy
Fury
Sorrow
Voices That Actually Feel
A narrator who breaks with sadness at just the right moment. A villain whose calm whisper turns to fury. A podcast host who sounds genuinely thrilled. 40 emotions, 5 intensity levels — every cloned or preset voice stays perfectly in character.
Direct emotion line by line
Emotion Engine
Pick any emotion — whisper, rage, heartbreak, storytelling — and dial the intensity. Assign different moods per line or paragraph. 60 speaker presets, voice cloning, and it all sounds like the same person. Not a robot.

Separate the Instruments
Take any song apart: vocals, drums, guitar, piano — each clean on its own track. Use Karaoke mode and mix in your own vocals or an AI-generated track.
Split any song into separate instruments
