ADOBE AUDITION 181 User Guide Listen If you have MIDI playback capabilities, you can listen to a preview of your sequence before actually applying it. Play begins at the leftmost note visible on the staff (which means play begins at the position you are scrolled to), and continues on to the end of the song. The music is played through channels 1 and 13 for Extended and Base level compatibility. Choose the desired instrument by typing its MIDI instrument number in the box to the right. You can record music played by the Listen preview button. Simply start Adobe Audition's recording process, then go into the Music dialog and press Listen. When the song is done, hit Cancel, and then press Adobe Audition's Stop control to terminate recording. Important: Make sure your sound card's mixer is set correctly for recording the MIDI channel. Tempo The tempo is given in quarter notes (beats) per minute. Your sample's length is the length of a quarter note. If your note is longer than the period determined by the tempo, then the notes will overlap. Key Choose a key for your song from the Key drop-down list. Only standard major key signatures are listed, so for a minor key simply choose the relative major (B flat for C# minor, for example). The key of C is the default. Octave This drop-down list lets you transpose the sequence by octaves. Choosing "C" plays the notes at normal transposition. Constant Duration When you check the Constant Duration box, all notes will be the same length as the original sample, regardless of pitch. The operation that does this takes longer to calculate, but high-pitched notes will be the same length as lower pitched notes. If the Constant Duration box isn't checked, the note is created by directly stretching or compressing the original sample, resulting in higher pitches being shorter than lower pitches. Exact Tune Check the Exact Tune box to tune your sample so that when played at A (above middle C), the frequency of your sample is at 440Hz. If the Exact Tune box isn't checked, your sample's original frequency will be played at A (above middle C). Time/Pitch The effects in this menu to are used to alter the time (duration) and pitch (tonality) of an audio file or selected range. Doppler Shifter Use Adobe Audition's Doppler Shifter effect to create the "fly by" sounds that are most familiar from cars racing by or airplanes flying overhead. Let's use a car for our example.
