Project Overview
AutoLyrixAlign is a next-gen AI-powered tool designed to bring precision and speed to the way lyrics are synced with music. If it's a studio track or a YouTube link, the platform simplifies word-level alignment of lyrics to audio, making it incredibly useful for music creators, educators, and platforms needing accurate synchronization. Tart Labs supported the product's development, helping bring this innovative idea to life through robust backend engineering, intuitive UI/UX design, and powerful audio-processing integrations.
About AutoLyrixAlign
AutoLyrixAlign is an intelligent web-based application built to align every single word of a song's lyrics with the corresponding section in the music file. Users can upload a music audio file or paste a YouTube video link, along with the corresponding lyrics text file. Once submitted, the system analyzes the audio, detects the lyrics, and generates a time-aligned version in formats like JSON, TXT, and LRC. The TXT format is also compatible with open-source audio tools like Audacity. It's a breakthrough for artists, producers, researchers, and karaoke developers who need fast, accurate lyric alignment without hours of manual effort.
The Challenge
Creating AutoLyrixAlign came with a set of exciting but demanding challenges. The core problem was building an AI model capable of handling varying audio quality, accents, timing inconsistencies, and diverse musical styles — all while producing frame-accurate word-level alignment. Another major hurdle was developing a user interface that could process large audio files quickly and still feel simple for non-tech-savvy users. The product also needed to manage multiple file formats and integrate directly with YouTube for real-time processing. Scalability, performance, and accuracy were at the heart of the engineering challenge Tart Labs helped tackle.
