TätigkeitsbeschreibungMyMusic plays and visualizes locally stored music in real time. The Java app provides a View based UI for choosing songs grouped by Playlists, Albums, Genres and Artists. The native project created from scratch is self directed and motivated by passion for trap music and seeing it visualized. Songs and their metadata are queried with Androids ContentResolver. To realize a high resolution visualization via FFT, low level Android Media APIs like MediaCodec and AudioTrack are used to get access to raw audio data. The FFT data is processed in realtime and rendered via Androids TextureView with the use of low level canvas drawing APIs. The application includes 5 different visualizations with special focus to visualize lower frequencies in an entertaining manner.
