	1. INTRODUCTION

TS-AudioToMIDI is a tool for automated recognition of polyphonic 
music. Music recognition is what musician does when playing 
music by ear and then recording it to staves. This program 
analyzes input waveform and tries to detect what notes were 
played.
TS-AudioToMIDI is able to both recognize pre-recorded audio 
files and perform recognition in real-time.
Recognizing pre-recorded music provides the possibility to 
convert digital sound (mp3, wav, CD tracks etc.) to MIDI 
format.
Real-time recognition is a process performed in real-time, 
without noticeable delay. Detected notes can be either recorded 
as MIDI file or played in real time, or both. 

As MIDI file is, in fact, a layout of music, you can change its
arrangement in contrast to digital sound. Instruments, 
number of voices or melody itself can be easily modified using 
any third-party score editor, which allows creating remixes or 
variations.
