## What is Apollo Sound Injector?

We're going to be focusing on development for Aleph Looper and Infinite Looper, and have decided to make this app free.  Enjoy!
--
Apollo Sound Injector makes it easy to stream audio from one iOS device to another.  Use the app Sidecar with the device that is sending audio, and Sound Injector on the device that needs to receive the audio -- we have two separate apps so that it's easy to know which end is which.

Both Sidecar and Sound Injector work with Inter-App Audio, so you can integrate iOS synthesizers and sequencers, and build complex audio processing chains.  And if you're making music, you should also take a look at Apollo MIDI over Bluetooth -- the fast way to send MIDI between multiple devices.

Secret Base Design has years of experience developing leading edge apps for serious musicians.   Our "Apollo" series of apps are designed to let you use multiple iOS devices, as well as desktop and laptop computers, to build an integrated and flexible music studio.

If you are using desktop DAWs, you can take advantage of Sound Injector on the desktop.

Note that with audio streaming over WiFi, there can be some latency, and performance will depend a great deal on your router, and the WiFi traffic.  Sound Injector features a novel latency reduction algorithm -- but there are limits to how far this can go, and very low latency connections may also introduce audio glitches.

### 1/5 — No longer working

*2019-09-24*

Apollo Remote Recorder is no longer available, and is required for this app to be of any use. Pointless. Too bad this was a great idea.

### 5/5 — Stellar

The Apollo series of apps allows users to do things that were previously impossible. Their functionality is streamlined and simple. Seamless audio integration between iOS and Mac OS. Brilliant!

### 5/5 — Great app.

*2014-10-01*

This app works great, also the recorder app that lets you save you work for export,I'm very new to making music with all my synths and music apps but the seem to link up great. This is just what I was looing for a way to save my work.

### 5/5 — As always very useful app from SBD!

*2014-09-23*

Always excellent quality and out of the box thinking.

### 5/5 — GENIUS APP!!!!!

*2014-09-23*

This guy is the Einstein of App design! Seriously. These Apollo apps can let you play your IPhone synths on your IPad, and now they can go straight into your Computer DAW with no wires. And it's free! Your Grandpa can be sitting in the room jamming along into your DAW with you on his IPad! It's amazing what this guy has allowed us to do. Get it!
