Filtrate is similar to having a third ear, listening to all the sounds around you while you enjoy other things on your iOS device such as watching a video, listening to music or playing a game. If an important sound occurs, such as a car horn, or an announcement, Filtrate will pause your music  play the sound live in your headphones. If you miss something, you can just rewind and listen again with Filtrate Instant-Replay. You can even speed up or slow it down until the sound is clear and audible . All without ever removing your headphones!

When auto-playback is on, Filtrate will automatically pause your music and playback important sounds as they are happening! For example: 

GOING FOR A JOG, WALK, OR BIKE RIDE - Don’t miss important sounds such as car horns or the sound of someone trying to get your attention. This is especially important for users of noise isolating headphones which block out most of the outside sounds. 

ON THE TRAIN OR PLANE - Enjoy your music without missing any announcements from the conductor or captain. 

AT THE AIRPORT - Relax before your flight with some tunes, but don't miss your boarding call or maybe gate change. 

AT THE TRAIN STATION - Nothing like great music with your morning commute, but don't miss important track/service announcements. Filtrate always adapt to the background noise. 

AT HOME - Like to get pumped up up while cleaning the house, or maybe just lazying around in your favorite chair. Enjoy, without missing a phone call or the door bell, or more importantly, the little one waking up from a nap. 

AT THE GYM - Enjoy Radiohead, Drake or David Guetta as loud as you'd like while working out without missing announcements on the PA. Filtrate! will adjust the sounds of the many machines going around you.
