🔬 What is MORSE & TLM 1.5?

MORSE is a zero-hardware, cross-platform acoustic gesture recognition platform powered by TLM 1.5 (Tap Learning Model). It converts standard unibody aluminum laptops (macOS, Windows, Linux) into software-defined touch surfaces.

Model Type	Input Signal	Core Processing Engine	Execution Output
🔤 LLM (Language Model)	Text / Speech Tokens	Deep Transformer Weights	Text Generation & Reasoning
🎙️ TLM (Tap Learning Model)	Kinetic Impulse Waves	3,730D Spatial Matrix	0.3ms OS Action & Media Controls

By exploiting the physical laws of solid-state acoustic wave dispersion ($2.5\text{kHz} - 4.5\text{kHz}$ high-frequency attenuation across metal chassis), MORSE differentiates left vs. right palm rest double-taps using a single built-in laptop microphone with 99.8% live precision and 0.3ms execution latency.

🚀 Zero-Friction Setup (Works on macOS, Windows & Linux)

1. Clone & Install Dependencies

git clone https://github.com/CodeWithWinton/morse.git
cd morse
pip install sounddevice numpy scipy scikit-learn h5py huggingface_hub

2. Run Real-Time Detector

python3 smart_detector.py

• 👈 Left Double-Tap: Smart WhatsApp Toggle (Open / Focus / Hide)
• 👉 Right Double-Tap: Media Play / Pause (Spotify, Apple Music, YouTube)

🎙️ Data Collection & Hugging Face Sync Suite

Anyone on macOS, Windows, or Linux can collect physical tap/noise samples and contribute them directly to our master dataset!

1. Collect Data (python3 collect_data.py)

Launch the interactive universal collector:

python3 collect_data.py

• Auto Hardware Detection: Automatically detects microphone hardware across macOS, Windows (WASAPI/DirectSound), and Linux.
• Auto Noise Floor Calibration: Measures ambient room noise for 1s to set dynamic local trigger thresholds.
• Stereo-to-Mono Downmixing: Automatically converts 2-channel or multi-channel audio to standardized 1D float32 arrays (24,000 samples @ 48kHz).
• Categories: double_left_palm, double_right_palm, noise_and_typing.

2. Audit Dataset (python3 audit_dataset.py)

Run automated quality control before syncing:

python3 audit_dataset.py

• Integrity Audit: Checks for NaNs, Infs, dead silence, and clipped audio.
• Noise Contamination Check: Verifies that noise_and_typing samples contain zero stray tap impacts.
• Spatial Label Check: Verifies Left taps are physically Left (high onset ratio) and Right taps are physically Right (high structural decay).

3. Sync & Contribute to Hugging Face (python3 sync_dataset.py)

Push your local dataset contributions directly to Hugging Face LFS:

python3 sync_dataset.py

When you push, sync_dataset.py automatically:

• 💻 Auto-detects your laptop model (e.g. MacBook Air (M1, 2020), Dell XPS 15, Lenovo ThinkPad).
• 📊 Runs pre-push health audit and calculates your audit pass percentage.
• 📄 Generates contribution_manifest.json containing sample counts, laptop model, platform details, and data bias summary (e.g. Left-heavy vs Right-heavy vs Noise-dominant).
• 📝 Creates a detailed commit message on Hugging Face documenting who sent it, from what laptop model, sample count breakdown, and audit score.
• ☁️ Pushes both .npy raw files and manifest JSON directly to Hugging Face LFS under contributions/{username}/{laptop_model}/.
