Endel
What is Endel?
Endel generates personalized soundscapes that adapt in real time to help you focus, relax, sleep, or stay grounded during activity. The audio engine uses patented Endel Pacific technology that reacts to inputs like time of day, weather, heart rate, and location instead of looping static tracks. The marketing site describes it as neuroscience-backed functional audio for everyday wellness.
Playlist apps give you fixed songs; Endel keeps regenerating sound on the device so the mix shifts with your context. Focus mode claims up to a 7x increase in sustained concentration versus playlists in peer-reviewed research cited on the site, and Relax, Sleep, and Activity modes each ship with generative visuals. The same engine runs across iOS, Android, macOS, web, Apple Watch, Alexa, Apple TV, and Fire TV.
Students, remote workers, people with ADHD, parents, and anyone fighting insomnia are the implied audience from focus and sleep landing pages plus App Store reviews quoted on endel.io. A free edition exists, while Premium unlocks all modes, offline playback, wearable integrations, and artist collaboration soundscapes like James Blake: Wind Down.
Altered Studio
What is Altered Studio?
Altered Studio morphs recorded or live speech into curated or custom voices for media production and real-time calls. Its speech-to-speech engine runs in the browser or locally on Windows and Mac, with a separate Real-Time Pro app for gaming, call centers, and voice restoration during video calls.
Most voice changers trade quality for latency or the reverse. Altered splits the stack: media production morphing targets recording quality on GPUs with post-edit refinements, while Real-Time Pro uses 1 to 4 CPU cores for low-latency skins, accent translation, and Euphonia support for dysphonia and disfluencies.
Podcasters, game studios, and call-center teams use it to dub multi-character scenes, swap accents on live calls, and clean noisy dialogue. The Studio page offers transcription in 75+ languages, translation, and text-to-speech voice-over in 70+ languages from major providers in one editor.
