Frequently Asked Questions
Will changing speed affect pitch?
By default, yes (chipmunk effect when faster). Some tools offer pitch-preserved speed change.
What speeds are useful for podcasts?
1.25× to 1.5× speeds up content without sacrificing clarity. Great for long podcasts.
Can I slow down audio for learning?
Yes! 0.75× or 0.5× speed is perfect for language learning or transcribing fast speech.
Will file size change?
Duration changes, so file size changes proportionally (2× speed = ~50% smaller file).
