LinkEffekt brings Ableton Link Audio to every AUv3 host. New in 2.0: it receives as well as sends. Stream any track between iPad and iPhone, from app to app on one device, into Ableton Live and back, or to a friend over the internet. Your host doesn't need to support Link Audio itself. ONLY IN LINKEFFEKT β€’ Right on the beat across devices. Other streaming plugins leave the network delay to the receiving side: either the whole receiving app plays later, or the stream arrives behind the beat. LinkEffekt Send plays its track ahead instead, by exactly the trip over the network, using the delay compensation of AUM and Logic Pro for iPad. The audio lands right on the beat on the other device, in both directions at once, from the first play, with nothing to set. β€’ Bar Sync for every other host. With any other sending app, and with Ableton Live, incoming audio locks to your bar: one bar late, but perfectly tight. Better late than never. β€’ Link Audio over the internet. Share a room code and jam with a friend anywhere, locked to your bars, peer-to-peer and encrypted. If the connection drops, it comes back by itself. WHAT YOU CAN DO β€’ Jam across devices: iPad and iPhone stream to each other over Wi-Fi, both ways at once β€’ Route audio between apps on one device: AUM into Cubasis, or track to track inside one host. No network: on this direct path LinkEffekt adds under 1 ms, plus one audio buffer when iOS runs the receiving app first. Want it right on your metronome? Switch on Bar Sync, one bar later β€’ Record in Ableton Live: every iOS track arrives in Live 12.4 as its own input, no interface, no cables. Live sends back, too. β€’ Record Ableton Move and Note: both stream over Link Audio, so LinkEffekt Receive plays them in any host, ready to record in Logic Pro, AUM or Cubasis. β€’ Monitor a band: sum several channels in one Receive, or give each its own track FEATURES β€’ Three plugins: Send, Receive as an audio effect, Receive as an instrument β€’ Local network over Wi-Fi, or by cable with Personal Hotspot for the steadiest connection β€’ Ableton Live 12.4 and later in both directions β€’ Ableton Move and Note 2.0 and later as sources β€’ Send at 48 kHz for receivers that need it, like Ableton Live β€’ Adjustable buffer against Wi-Fi gaps β€’ Gain, stereo pan and click-free mute on every channel β€’ Stereo level meters β€’ Channel names carry the device, like "Channel 1 Β· iPad", and update live on every receiver β€’ Mute Local Output, so a sent track isn't heard twice β€’ Bypass all LinkEffekt Sends with one switch: your session plays on the device instead of streaming β€’ Live Mode for playing live on the sending device β€’ Nudge and Link Offset for fine timing β€’ Ableton Link settings in every plugin β€’ iPhone and iPad FREE TO START One Send and one Receive are free with no time limit: full quality, on the beat, Bar Sync included. A single in-app purchase unlocks unlimited Sends and Receives, several channels in one Receive, and Online mode. No subscription. IMPORTANT: OPEN THE APP ONCE After installing, open the LinkEffekt app once and allow Local Network access. Without it the plugins can't find each other and stay silent. REQUIREMENTS β€’ An AUv3 host such as AUM, Cubasis, Loopy Pro, Drambo, GarageBand or Logic Pro β€’ iOS 15 or later β€’ For Ableton Live, Move or Note: Live 12.4, Move 2.0 or Note 2.0 or later on the same network β€’ For Online mode: the in-app purchase on both sides

About

Audiotest (hearing_app)

Features
Read full description

Check how you hear. Take a sound apart. Build a noise you have never heard. The spectrum shows what speech, music, or the quiet around you is made of. Noises stack in layers: a steady bed, a rustle, a hum. That becomes a sound scene of your own. Save it and play it again. Glide a tone from a low hum up to a thin high note and notice where it disappears. The hearing chart is saved too, so you can compare it with last time. A hearing-aid–like imitation is available: phone-microphone sound in headphones. Beta, not a hearing aid and not a medical device. A sweep tone, a sine-wave generator, a spectrum analyzer, and a sound level meter are available, along with a simulation of reduced hearing, the ability to create different noises, and export of any data. Hearing can be checked with spoken digits, including in noise, and with the usual tones, giving a chart similar to an audiogram at the doctor’s. This is for you, at home, with headphones. It is not a visit to the doctor: if your hearing worries you, see a professional.
