public function setParameters(aSampleRate:int, aSequenceMS:int, aSeekWindowMS:int, aOverlapMS:int):voidSets routine control parameters. These control are certain time constants defining how the sound is stretched to the desired duration. 'sampleRate' = sample rate of the sound 'sequenceMS' = one processing sequence length in milliseconds (default = 82 ms) 'seekwindowMS' = seeking window length for scanning the best overlapping position (default = 28 ms) 'overlapMS' = overlapping length (default = 12 ms)

| DEFAULT_OVERLAP_MS | constant |
public static const DEFAULT_OVERLAP_MS:int = 8Overlap length in milliseconds. When the chopped sound sequences are mixed back together, to form a continuous sound stream, this parameter defines over how long period the two consecutive sequences are let to overlap each other. This shouldn't be that critical parameter. If you reduce the DEFAULT_SEQUENCE_MS setting by a large amount, you might wish to try a smaller value on this. Increasing this value increases computational burden and vice versa.
| DEFAULT_SEEKWINDOW_MS | constant |
public static const DEFAULT_SEEKWINDOW_MS:int = 0Seeking window default length in milliseconds for algorithm that finds the best possible overlapping location. This determines from how wide window the algorithm may look for an optimal joining location when mixing the sound sequences back together. The bigger this window setting is, the higher the possibility to find a better mixing position will become, but at the same time large values may cause a "drifting" artifact because consequent sequences will be taken at more uneven intervals. If there's a disturbing artifact that sounds as if a constant frequency was drifting around, try reducing this setting. Increasing this value increases computational burden and vice versa.
| DEFAULT_SEQUENCE_MS | constant |
public static const DEFAULT_SEQUENCE_MS:int = 0Default length of a single processing sequence, in milliseconds. This determines to how long sequences the original sound is chopped in the time-stretch algorithm. The larger this value is, the lesser sequences are used in processing. In principle a bigger value sounds better when slowing down tempo, but worse when increasing tempo and vice versa. Increasing this value reduces computational burden and vice versa.
| USE_AUTO_SEEKWINDOW_LEN | constant |
public static const USE_AUTO_SEEKWINDOW_LEN:int = 0Giving this value for the seek window length sets automatic parameter value according to tempo setting (recommended)
| USE_AUTO_SEQUENCE_LEN | constant |
public static const USE_AUTO_SEQUENCE_LEN:int = 0Giving this value for the sequence length sets automatic parameter value according to tempo setting (recommended)
