Using the Sync Track's Waveform Display to Help Create Dynamics Lets IMPORT two more components from our Sound Family called Spankin_fill_01.aif and Spankin_crash.aif. Sound Family chunks have been engineered without drum fills and cross-phrase melodies for looping purposes. Because of the uniqueness of every multimedia project, having fills and melodies as part of the chunk would be a disadvantage. But fills and melodies add impact and dynamics, right? Isn't that why traditional loops get so mundane? The answer is, yes. Loops alone are almost the opposite of dynamic and compelling. However, using the sync track and layerable audio components like drum fills, give you the ability to add these impact building elements back into our mix... when YOU want them. Fills provided with Sound Families are always edited to be one or two full measures in length. This means that they will always align with a waveform spike on our sync track.
Dealing with Seams and timing inconsistencies Seams are small gaps or pauses between chunks or loops that are placed back to back. Depending on processor speed, playback quality may vary within Flash, causing small seams between chunks. However, if all chunks have been inserted in the correct frames, this should not be a problem upon export to SWF format. If seams still exist in your exported movie, there are a couple of possible causes and resolutions. The first reason you may experience seams is due to mis-matched frame rates and beats per minute. Flash's timing method is frames per second, while music is measured in beats per minute. The average ear can hear a 1/100 of a second gap in a solid music stream. So, if your frame rate is set at 10 frames per second, and your first chunk ends in the middle of a frame, you will have a 5/100 of a second space before the next chunks starts, causing a seam. This problem is solved by choosing frame rates and beat-per-minute rates that divide evenly. Basically the number of frames per beat must be a whole number. To illustrate this better, go to MODIFY> MOVIE and change your frame rate to 12 FPS. Notice in the timeline that the audio waveforms no longer end precisely at the end of a frame. All DoReMedia Sound Families are recorded at optimal BPM rates and engineered to have timing accurate to 1 millisecond. DoReMedia provides a BPM to Frame Rate calculator which is available free for all registered users.
