A Note About Accuracy and Speed
Several factors affect the accuracy of the intelliScore's proprietary music recognition algorithm in addition to the limits imposed by MIDI. Non-tuned sounds such as drums, cymbals, applause, and noise are not converted to MIDI. However, if you record the music yourself, recognition will be much improved if you leave percussion out of the recording. The tone quality of different instruments affects recognition accuracy. A bright instrument, such as a trumpet for instance, is not recognized as accurately as a flute, which produces a dull, steady tone. As a result intelliScore will recognize some forms of music quite accurately, while it may refuse to recognize others.
Music with longer notes tend to be recognized more accurately. Accuracy can be improved by adjusting the recognition settings rather than accepting their default values. There is a trade-off, as greater accuracy usually results in lengthening the time that intelliScore requires to recognize a piece of music. The best way to reduce recognition time without compromising accuracy is to run intelliScore on the fastest processor possible.
When evaluating how well intelliScore recognizes a piece of music, it is important to judge what the MIDI file sounds like rather than what it looks like after being notated. MIDI files do not contain enough information to specify exactly how it should be notated. As a result, two different music notation software programs will interpret the exact same MIDI file differently, creating sheet music that is different in appearance. In a similar fashion, published sheet music often represents a copyist's interpretation of a piece of music.
