Hello friends. I don't know exactly if the problem is with my device or with the general power amplifier. However, when the Poweramp's speed is 1.22 and higher in the accelerator setting, the squeaking sound is distorted. Bass-like sounds are added to the songs at 1.33x speed, but these added sounds are definitely annoying and can disrupt my speaker. If this problem is not on my device, please fix it in the next update, fix it.
