Features

• Voice and expression — use a reference voice, match a reference performance, adjust emotions, or describe the delivery in words.
• A complete audio workflow — import or record reference audio, trim clips, preview speech, and export your work.
• Voice design and cloning — VoxCPM2 offers text-guided voice design, controllable cloning, and transcript-assisted cloning with automatic multilingual handling, and 48 kHz output.
• Music generation — describe a style, write lyrics with section markers, and generate full songs or instrumentals with ACE-Step 1.5; every take is kept as a version to compare.
• Score — write each part by bar and beat, import MIDI or let an Agent write the score, then render it with a General MIDI sound font and a role-based mix; results are exactly repeatable and export to MIDI and stems. See Score.
• Optional AI service — connect DeepSeek, Qwen, Kimi, OpenAI, Anthropic, Ollama or any compatible API to let AI write arrangements and lyrics; keys stay on this computer. See AI service.
• Local models — run IndexTTS 2.0 / 2.5, VoxCPM2, OmniVoice, Qwen3-TTS, Breeze TTS 2 and Kokoro through audio.cpp, with resumable model downloads and GGUF import.
• Hardware acceleration — Metal on Apple Silicon; CPU, NVIDIA CUDA, and experimental Vulkan on Windows.
• Agent Skill & MCP — ask your AI agent to set up local speech generation and create voiceovers from text and reference audio.
