AudioToMidi converts a standard audio signal to a MIDI messages in real-time. The resulting MIDI messages can be played through a standard MIDI device, PC speaker or built-in sequencer. The audio signal spectrum is displayed in a special window in real-time. Note: PC speaker is disabled under Windows NT.

Features

• Input audio signal volume normalization.
• Input audio signal correction by built-in graphic equalizer.
• Audio signal frequency deviation compensation from standard note frequencies (guitar sound and the tuning fork discrepancy).
• Note sensor selectivity for the relation of one note to the adjacent note signals.
• Note volume filter; ignores low notes and noise.
• Output note filter; ignores the notes of pre-set loftiness in MIDI signal generation. The note interval and/or presumed key can also be set.
• Note duration filter; ignores accidental short notes when writing to the built-in sequencer.
• Graphic simulation of the first four harmonics of recognized instrument or voice.
• MIDI signal transposition. Resulting note loftiness shift at the integer number of semi-tones.
• MIDI instrument selection for signal generation.
• Volume selection for resulting note.
• MIDI channel selection during MIDI signal generation.
• Monophonic mode. Allows the lowest note selection from a number of simultaneous notes, thus providing the separation of the first instrument/voice harmonic, and errorless conversion of monophonic melodies.
• The general setting is automatically saved. Separate saving, opening and resetting of the equalizer, harmonic model and filter settings are provided.
• The conversion result is presented in real-time by highlighted piano keys. The piano keyboard window can also be used to generate the sound corresponding to the pressed key.
• Guitar tuning through signal spectrum representation.
• Built-in sequencer allows opening and playing MIDI (*.mid) and RIFF MIDI (*.rmi) files. New tracks can be also added to the open files.
• Ability to operate with an external software sequencer. Sonic Foundry Virtual MIDI Router (VMR) is recommended.

Requirements
