Realtime recognition allows you to capture sound either from a microphone or any other WAVE input device chosen and perform transcription in real-time, with instant MIDI output. You can expect approximately 50-70 ms delay for realtime recognition if your MIDI hardware is fast.

Realtime recognition quality is usually poorer than the quality of pre-recorded audio recognition. Realtime recognition algorithm has no ability to "overview" all the piece at once, and it has to output notes as soon as they appear, not as they end. This makes virtually impossible to determine note volumes and leads to much higher error rate. You should always record a file and recognize it offline unless you really need recognition in realtime.

Realtime recognition feature is useful for replacing instrument when playing or singing live, or to control external devices such as  synthesizer or light show equipment.

Realtime Recognition is performed in following steps:

•	Start Realtime Module (Click Realtime). Recognition is controlled by Recognize now checkbox, enabled by default.

•	Check the input source. You can select input source with Windows Mixer (Click Mixer Settings). See documentation on Windows Mixer on how to do that.

If you need to record recognized notes:

•	Start recording by pressing Record button.

•	Save it (Click Save). The trial version allows you to save up to 10 seconds of MIDI.

Recorded notes differ from the ones played in realtime. Before saving a record, note volumes are calculated, and "Minimal Note Duration" setting is applied. The contents of MIDI Options tab also influence saved MIDI file.
