Akoff Music Composer is a song making software that assists in music creation. Hum your melody into the microphone and Composer captures the audio, transcribes it into the MIDI sequence, makes chords and arranges the song. Neither a MIDI keyboard nor any musical experience is required to create music. To create a MIDI sequence for a melody recorded in audio format (WAV, MP3, etc.) a musician must determine pitch, velocity and duration of each note being played and record these parameters into a sequence of MIDI events. A music transcribing software must do the same things. Even for a single instrument composition it is not a simple task, because an audio recording contains sampled waveform signals and doesn't contain any music specific data. Akoff Music Composer normally transcribes polyphonic music with one instrument or voice. This means you won't get the appropriated results if you try to recognize many instruments playing at the same time especially with drums. After transcibing Composer analyzes the harmonical structure of the melody line and makes the chord progression.
