PROFILE

Lucas Newman

Worked on the Blaizzy/mlx-audio repository, delivering modular audio processing features and robust model integrations over five months. Developed custom STFT/ISTFT routines in Python to reduce dependencies and improve maintainability, and introduced neural audio codecs for higher quality and compression. Integrated Wav2Vec2 and transformer-based TTS models, refactored Spark pipelines, and optimized audio codec performance for scalable deployment. Addressed bugs in ISTFT window handling and TTS token semantics, enhancing reliability and output coherence. Expanded test coverage and implemented per-segment cache optimizations, focusing on efficient, reproducible workflows. Demonstrated expertise in audio processing, deep learning, and model integration using PyTorch and Spark.

March 2026 monthly summary for Blaizzy/mlx-audio: Delivered key STT and TTS improvements and a token semantics bug fix. STT Output Length Expansion extended default max tokens from 128 to 8192, enabling longer outputs and reducing post-processing. Added Fish Audio S2 Pro TTS model support for voice cloning and multi-speaker TTS. TTS Token Semantics Coherence Fix improved replacement of semantic tokens to handle repeated tokens more coherently. These changes improved downstream processing, expanded use cases, and strengthened model reliability, delivering measurable business value in end-user experience and deployment flexibility.
