TS-AudioToMIDI

TS-AudioToMIDI is an application that you can use to convert an audio signal into a MIDI sequence. With it you are able to transform MP1, MP2, MP3, MPP, MPA. AIF, SND, AU and WAVE files to MIDI.
This way you can compress any of the previously mentioned audio formats into a track that can be easily uploaded to a website or attached to an interactive piece of software without having to worry about it taking up too much disk space.
Moreover, once a track is converted into MIDI format, its structure and notes can be modified in a simple manner. Instruments, voices and even the melody can be altered to fit your needs or taste. Doing so makes TS-AudioToMIDI a handy tool to have for when you need to create or customize a song and load it on your phone as a ringtone.
The application displays a comprehensive interface and offers you quick access to playback controls, a Wave recorder, spectrum analyzer and keyboard, a graphic equalizer, adjustments for the noise gate threshold, the instrument selector and much more.
TS-AudioToMIDI features monophonic and polyphonic recognition modes and uses four algorithms. The application also provides the use of both real-time and pre-recorded modes for sound recognition.
With this program you benefit from manual and auto tuning for the audio signal, frequency deviation, CD track input and real-time spectrum analysis of the loaded song. It also comes with a note duration filter that can be used to ignore short notes.
To help you out with track editing, TS-AudioToMIDI supplies a large library of piano, bells, organ, guitar, trumpet and many more instruments which you can add with a simple click.
As far as the note detection algorithms go, you can choose between Poly Sensors, Mono Correlator, Mono Breaking, Mono Sensors and Beat Detection.
