Realtime Module

Realtime Recognition window allows you to recognize incoming audio into MIDI notes in real time. See Realtime Music Recognition for details. Realtime Module is called by pressing Realtime button on the main window toolbar.

 

 

Record MIDI starts recording of the recognized MIDI notes (Recognize now box should be checked).

Auto Record starts recording of MIDI notes as soon as the first note is detected.

Stop stops recording. If you press Record MIDI again, your previous record will deleted and you will start recording from the beginning.

 

Options invokes Options Dialog and allows you to choose a WAVE input and MIDI output devices.

Settings allows you to set up Realtime Recognition Parameters and output MIDI file options.

Equalizer displays the Equalizer window. Equalizer settings are applied instantly, you do not need to close it to see the result.

Windows Mixer  enables you to set up the system mixer.

 

The following options and settings are also available:

 

Recognize now checkbox enables Realtime Recognition of the incoming audio.

Play MIDI Notes checkbox enables instant simultaneous playback of the detected notes via MIDI.

Recorded Data indicator shows you the duration of the recorded MIDI sequence.

<< and >> buttons show and hide the sliding spectrogram.

 

Algorithm list lets you choose among several recognition algorithms. Chosen algorithm enables extra controls for adjustment.

Polyphony slider appears when "Polyphonic - Sensors" algorithm is selected. It allows you to adjust the threshold for detecting several notes that sound simultaneously.

Harmonic Filter slider appears when "Monophonic - Sensors" algorithm is selected. It allows you to avoid capturing of the overtones instead of fundamentals.

Noise Gate slider allows you to adjust the noise filter to prevent undesirable sounds being recognized as notes. Adjust it carefully, in order not to lose the essential sounds.

 

Level indicator shows you the level of incoming sound that can be adjusted by the system mixer (see Mixer Settings button). Recommended signal level is approximately -20dB to -5dB.

 

You may adjust the recognition parameters without breaking the recognition process,  all changes are applied immediately. However when recording MIDI notes some controls are disabled.

 

To finish recognition process and proceed with the recognized MIDI notes press Done. The new file will be opened in a new MIDI window.

 

To cancel the recognition and discard any recorded notes press Cancel.

 

Note: Use Audio File Recognition whenever you can first record a file and then recognize it - it will yield better results.
