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!


✓ Instant-Replay
Filter can continuously record up to the most recent few minutes, so even when you're not listening, Filter is... If you miss anything just rewind and play it again!

✓ Automatic volume control
Never touch your volume control again!! Let Filter raise and lower your music volume as the noise level in your environment increases or decreases. Filter makes fine grained changes that cannot be easily be made using manual controls.

✓ Automatic playback
When auto-playback is on, Filter 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. Filter 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. Filter! will adjust the sounds of the many machines going around you.

✓ Control your iOS music player
You can now fully control your iOS music player right from Filter!
・See album art
・Swipe to change tracks

Do you ever just want to know a little more about the artist or song you're listing to? With Filter, you can search the web, images or videos of the current song, album or artist with a single tap.

✓ Live playback when music is paused
When enabled, Filter will automatically start playing live sounds when you pause the music so if you want to have a quick conversation, no need to remove your headphones!

✓ Voice Equalizer
Helps reduce background noise and makes it easier to understand spoken words in loud environments.
