Louden: Video Volume Booster

Video too quiet? Louden is a video volume booster that makes the sound in your videos louder, right on your phone. Move the slider and hear the change while the video plays, then save it. INCREASE VIDEO VOLUME UP TO 3000% • Auto picks the right volume for each video • Or set it yourself with the slider, from 100% to 3000% • Switch between Original and Louder to hear the difference • Tap the waveform to jump to any moment NO CRACKLE AT HIGH VOLUME Most video volume boosters just turn everything up, so loud parts distort. Louden holds back the loudest moments, so voices get louder and the sound stays clean. FULL-LENGTH VIDEOS, FREE No 30-second limit. Make long videos louder: lectures, birthday speeches, interviews, class recordings and screen recordings. THE PICTURE STAYS THE SAME Only the sound changes. Your video keeps its resolution, frame rate and quality, and the audio keeps its original quality. CLEARER VOICES Turn on Clearer voices to cut low rumble and bring speech forward. Good for wind, traffic and phone recordings. It works like a simple video sound enhancer. PRIVATE AND OFFLINE Everything happens on your phone. Your videos are never uploaded, and Louden works without an internet connection. SAVE AND SHARE Save the louder video to your gallery (Movies/Louden) or share it straight to WhatsApp, Instagram, YouTube or any app. FREE AND PRO Louden is a free video volume booster with no sign-up. The free version shows a short ad after a video is done. Louden Pro removes ads and adds: • Batch: make several videos louder at once • Clearer voices Pro is a one-time purchase or a yearly plan. You can also try a Pro feature once by watching a short ad. Use Louden as an audio booster for videos, a video volume increaser for quiet clips, or to boost video audio before you post.
