• Project Background
• Design a visually stunning and functionally
  powerful system which can effectively morph dance
  tracks using technologies and techniques far
  beyond that possible using standard analogue
  equipment.
• Built to support a range of users, from a home
  user with an interest in mixing music, to
  professional musicians and DJs.
• Provide a simple, one-click approach to morphing
  entire playlists of songs.

• Technologies Implemented The Solution
• Java Sound API - Extensive use of the Java Sound
  API to provide low level access to the digital
  audio.
• Waveform Processor, Low Pass Filters
  Normalisation Implemented to provide powerful
  processing of digital audio used throughout the
  system within the automatic algorithms and also
  for the visual waveforms.
• Start / End Point Detection - Good Start and End
  points are required for an effective morph and
  bridge period, therefore an automatic search
  algorithm has been implemented to make this
  process easy for the user whilst also allowing
  manual manipulation via a specifically designed
  user interface.
• BPM (Beats Per Minute) Detection - Beat rates
  are required for successful morphing therefore we
  have implemented both an automatic algorithm and
  two techniques for manual beat detection/calculati
  on.
• Digital Audio Manipulation within the Morph
  Process When generating bridges between tracks,
  several techniques were used Incremental beat
  rate increase/decrease, smooth cross fading
  between tracks, automatic bridge start/end
  correction and finally bass cuts. Together these
  provide a powerful and effective mix.
• Internal Meta Data Xerces XML DOM parser used
  to read and store meta data about various tracks
  used within the system and also within the
  load/save process of playlists.
• Custom Music Morpher Player Providing all the
  required functionality of a music player, Music
  Morpher includes a player interface which is
  linked into the entire system.
• GUI / GUI Handler / Controller / Service
  Framework Used in business projects to separate
  the application logic into a series of layers to
  support easy development and extensibility of the
  system.
