Cifre.ME: Gerador de Cifras automáticas

Abstract

Onamusical journey, it is common for beginners to face certain difficulties when trying to play their favorite songs. This mainly occurs due to the complexity of the chords, which can be challenging to execute. Additionally, beginners often encounter the frustration of not finding the chord of their favorite song on online platforms. This happens because the specific chord has not yet been submitted by any user on these platforms, thus becoming unavailable for consultation. In this context, the project addresses the implementation of Cifre.ME, a web platform whose main objective is to automate the generation of musical chords, as well as assist beginner musicians in playing their songs in a simple and intuitive way through simplified chords. The application uses an API specialized in extracting information from audio files, allowing for chord identification, transcription of lyrics, and even generating timestamps to align the chords with the song lyrics. Therefore, Cifre.ME presents three main functionalities. The first one is the file upload, where the user selects a preferred song in “.mp3” or “.webm” formats for the necessary processing to generate the chord. Additionally, there is an option to add a YouTube URL containing the desired song. Finally, the user also has the possibility to download the chord in “.txt” format. During the application development process, various cutting-edge web development technologies were employed. Initially, Figma was used to create the application prototype, allowing for a preview and detailed visualization of its structure and functionalities. Then, for the user interface construction, ReactJS was chosen, a powerful tool enabling the creation of dynamic and responsive interfaces. For the server-side of the application, FastAPI was chosen, an agile and efficient framework enabling the rapid development of robust APIs. Furthermore, the Music.AI API was integrated into the platform, responsible for providing essential data for the application’s operation, such as chord information, lyric transcriptions, and timestamps to align the chords with the song lyrics. Regarding the product evaluation, a comprehensive internal testing plan was devised and executed to validate the functioning of all application functionalities.
