The 15-second cutdown, done right
Fifteen seconds is the workhorse length: pre-roll, bumper, Reels/TikTok/Shorts, a tight cutdown of a longer spot. The wrong way to hit it is to speed the whole clip up — you get a rushed, high-pitched read. Audio2Time trims the pauses first (often enough on its own), then applies only a small pitch-preserving stretch for the remainder. You get 15 seconds on the nose, sounding natural, with loudness set for your platform.

Frequently asked questions
How do I make audio exactly 15 seconds?
Upload it, set the target to 15 seconds, download. The output is exactly 15 seconds — pauses trimmed, pitch preserved.
Is 15 seconds enough for a voiceover?
Roughly 35–45 words of clear speech. A slightly-over read usually fits after trimming pauses.
Can I turn a 30-second read into 15?
Only partly — big cuts need a shorter script. Audio2Time refuses speed-ups above ×2 (unintelligible).
