Hi.
I process file "sinus_pcm-signed_16bit.wav" (further as "Input file") with default parameters (-tempo=0 -pitch=0 -rate=0) using SoundStretch 2.1.1 for Windows [15-Nov-2018]. SoundStrecth creates file "sinus_pcm-signed_16bit_tempo0_pitch0" (further as "Output file").
Output file should not differ from Input file because default parameters were used. But as i can see it is not.

For example:
Input file consists of parts of the same data (sinus with different frequencies). Size of every part is 529200 samples (see image "1.jpg" in attachments).
But in Output file these parts have different sizes (529177, 529200, 529225 etc.) (see image "2.jpg" in attachments).
Can you fix it or explain why this is happening?
