adjust the Pulse Analysis parameters, then click Audition to see the results and
decide if the pulses are satisfactory. The Pulse Analysis parameters are as follows:
In the second step, you set the Timing Synthesis parameters to determine how the
pulses are converted to musically meaningful data. The Timing Synthesis
parameters are as follows:
Parameter/Option Meaning
Preset field Use this field to choose and enter presets. Click
the Save button to save any group of new
settings after you enter a name in the Preset
field. Click the Delete button to delete any
selected group from the Preset field.
Trigger Level (db) The loudness of audio needed to trigger a new
pulse.
Minimum Length (ms) The minimum allowable amount of time
between pulses. If you are working with
dynamic source material, and Extract Timing
seems to generate clusters of pulses that seem
incorrect, you should experiment with
increasing the value of this parameter.
Find a Steady Rhythm Tells SONAR to look for a steady rhythm among
all the pulses it finds. For example, if you're
analyzing a drum track that consists of a steady
beat on the snare and kick-drum, but which also
has some syncopated accents, you can use this
option to ignore the syncopation and retain only
the backbeat.
Parameter/Option Meaning
Insert Tempo Changes Tells SONAR to insert tempo changes in the appropriate
places in your song to ensure that the sequence plays in time
with the rhythm track. Remember to also set the Expected
Pulse Duration, because it defines the metronome markings
for all tempo changes.
Expected Pulse Duration The musical time value for each pulse that was found. For
example, if you're analyzing a drum beat that has steady
eighth notes on the high-hat, you should set this value to
Eighth for the correct tempo changes to be inserted.
