What is OptiClone CLAUDE.md?

A project instruction file for OptiClone, a standalone Windows application that clones voices using Python and the LuxTTS model. It records the project's structure, technical decisions, dependencies, and commands for building and running it.

Use it when developing, running, or maintaining the OptiClone voice-cloning application. It helps locate the main program, user interface, audio tools, model wrapper, settings, and launch commands.

It gives a coding agent the background needed to work on OptiClone without rediscovering how the project is organized or which choices it depends on.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00601	$0.00601
Opus 5.5	$0.00240	$0.00240
Sonnet 5.5	$0.00120	$0.00120
Haiku 4.5	$0.00060	$0.00060

Security

Grade A, and why

OptiClone CLAUDE.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

OptiClone — Project Tracking

Overview

OptiClone is a standalone Windows PC voice cloning application built with Python. It integrates the LuxTTS model (by YatharthS, based on ZipVoice) for high-speed (150× realtime) zero-shot voice cloning at 48 kHz fidelity.

Key Decisions

Decision	Choice	Rationale
Model source	HuggingFace `YatharthS/LuxTTS`	Official weights; auto-downloaded on first run
UI framework	CustomTkinter	Modern dark-mode look; pure Python; lightweight
Backend	Direct in-process calls	No FastAPI needed for a local desktop app
Audio I/O	soundfile + sounddevice	Cross-platform recording & WAV export
Sample rate	48 000 Hz	Native LuxTTS output rate

LuxTTS API Reference (from upstream repo)

from zipvoice.luxvoice import LuxTTS

lux_tts = LuxTTS('YatharthS/LuxTTS', device='cuda')       # or 'cpu'
encoded  = lux_tts.encode_prompt('ref.wav', duration=5, rms=0.01)
wav      = lux_tts.generate_speech(text, encoded,
              num_steps=4, t_shift=0.9, speed=1.0,
              return_smooth=False)

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
