A Note About Accuracy and Speed
Several factors affect the accuracy of the intelliScore's proprietary music conversion algorithms in addition to the limits imposed by MIDI. Non-tuned sounds such as drums, cymbals, applause, and noise are not converted to MIDI unless you are using intelliScore's drum recognition feature. However, if you record the music yourself, conversion will be much improved if you leave percussion out of the recording. The tone quality of different instruments affects conversion accuracy. A bright instrument, such as a trumpet for instance, is not converted as accurately as a flute, which produces a dull, steady tone. As a result intelliScore will convert some forms of music quite accurately, while it may refuse to convert others.
Music with longer notes tend to be converted more accurately. Accuracy can be improved by adjusting the conversion 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 convert a piece of music. The best way to reduce conversion time without compromising accuracy is to run intelliScore on the fastest processor possible and reduce the pitch range to the smallest range that includes all the pitches in the audio.
When evaluating how well intelliScore converts 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.
