Frequently Asked Questions
- Does changing speed affect pitch?
- Without pitch correction, faster = higher pitch. Our tool can preserve original pitch while changing speed.
- What's a good speed for podcasts?
- 1.25x-1.5x is comfortable for most people. 2x takes practice. Start slower and work up as your brain adjusts.
- Why slow down music?
- Musicians slow down difficult passages to practice at a manageable tempo, then gradually increase speed as they improve.
