The synchronized overlap-add (SOLA) algorithm is an audio time-scale modification technique. It operates in the time domain and uses a correlation technique to ensure that synthesis frames overlap in a synchronous manner.
Usage: sola <source> <destination> <alpha> [<framesize>]
source Specifies the file to be time-scale modified
destination Specifies the filename for the new file
alpha Specifies the time-scale factor [0.5 to 2.0]
framesize Specifies the size of the overlapping frames
[25 to 1000] {default = 160}
