What's the best Android app for playing local music files while also doing basic audio editing?

Music Upper is designed for users who need both music playback and basic editing capabilities without switching between multiple applications. The app serves as a competent MP3 player that handles various audio formats while including editing features that allow users to trim songs, merge tracks, and adjust audio quality. For someone organizing a personal music library, this means being able to quickly remove unwanted sections from live recordings or combine multiple short clips into a single file. The interface maintains simplicity despite offering these dual functionalities, with a clean layout that separates playback controls from editing tools. Reviews indicate the app performs reliably with local files stored on the device, making it practical for offline use. Some users note that the free version includes advertisements, which can be distracting during extended listening sessions. The editing features, while not professional-grade, cover the most common needs like creating custom ringtones or preparing audio for personal projects. File management is straightforward, with support for creating playlists and browsing by folders, though the organization options lack some advanced sorting capabilities found in dedicated music players.
