model transcription with music.ai api)<br> LLM used for further abstract analysis (key/tonal modulation correction, song analysis, and structural segmentation through color coded in the beat chord grid).</p> <p>The webpage is at: <a href="https://www.chordmini.me" rel="noopener noreferrer">ChordMini</a><br> The repo is at <a href="https://github.com/ptnghia-j/ChordMiniApp" rel="noopener noreferrer">Github</a> if you are interested.</p> <p>Feedback, questions, suggestions are very welcome and any contribution is appreciated!</p> <p><a href="https://media2.dev.to/dynamic/image/width=800%2Cheight=%2Cfit=scale-down%2Cgravity=auto%2Cformat=auto/https%3A%2F%2Fdev-to-uploads.s3.amazonaws.com%2Fuploads%2Farticles%2Fr513u8wyg2ktddomydzn.png" class="article-body-image-wrapper"><img src="https://media2.dev.to/dynamic/image/width=800%2Cheight=%2Cfit=scale-down%2Cgravity=auto%2Cformat=auto/https%3A%2F%2Fdev-to-uploads.s3.amazonaws.com%2Fuploads%2Farticles%2Fr513u8wyg2ktddomydzn.png" alt="Home page" width="800" height="466"></a></p> <p><a href="https://media2.dev.to/dynamic/image/width=800%2Cheight=%2Cfit=scale-down%2Cgravity=auto%2Cformat=auto/https%3A%2F%2Fdev-to-uploads.s3.amazonaws.com%2Fuploads%2Farticles%2Fz7zcb4cywbvou57p1vk7.png" class="article-body-image-wrapper"><img src="https://media2.dev.to/dynamic/image/width=800%2Cheight=%2Cfit=scale-down%2Cgravity=auto%2Cformat=auto/https%3A%2F%2Fdev-to-uploads.s3.amazonaws.com%2Fuploads%2Farticles%2Fz7zcb4cywbvou57p1vk7.png" alt="Guitar diagram" width="800" height="406"></a></p> <p><a href="https://media2.dev.to/dynamic/image/width=800%2Cheight=%2Cfit=scale-down%2Cgravity=auto%2Cformat=auto/https%3A%2F%2Fdev-to-uploads.s3.amazonaws.com%2Fuploads%2Farticles%2F3yqypnzeeaxrklvqcc89.png" class="article-body-image-wrapper"><img src="https://media2.dev.to/dynamic/image/width=800%2Cheight=%2Cfit=scale-down%2Cgravity=auto%2Cformat=auto/https%3A%2F%2Fdev-to-uploads.s3.amazonaws.com%2Fuploads%2Farticles%2F3yqypnzeeaxrklvqcc89.png" alt="Beat chord grid" width="800" height="424"></a></p> webdev mir ai fullstack
