Audiobus: Use your music apps together.

What is Audiobus?Audiobus is an award-winning music app for iPhone and iPad which lets you use your other music apps together. Chain effects on your favourite synth, run the output of apps or Audio Units into an app like GarageBand or Loopy, or select a different audio interface output for each app. Route MIDI between apps — drive a synth from a MIDI sequencer, or add an arpeggiator to your MIDI keyboard — or sync with your external MIDI gear. And control your entire setup from a MIDI controller.

Audiobus is the app that makes the rest of your setup better.

Anyone struggling with EQ, Compression or Reverb should watch this video

1/2 an hour but totally worth it.
This video is focused on guitars, but the principles in it work for everything.
It explains using EQ and uses ProQ2 for the demo, it covers attack times for compression and then using delay instead of reverb.....
What I like about this vid is that it explains not only how, but WHY.


  • Nice! Thanx for sharing.
    I like the vegatables analogy! He does do a good job of explaining how and why. The vid showed me that if you train your ears it makes a huge difference to you mix.

  • Ya this was really good!

  • This is great and thanks for sharing, but my god he knows how to labour a point. The whole video could have literally been 3 minutes long!

    Great video, thanks! Makes me start thinking about getting ProQ2.

    Any suggestions for a good standalone delay with a lot of presets?

    1. Kozmonaut
    2. Multi-tap Delay

    Many of these apps work along this spectrum of effects:
    1. SHORT DELAYS: Reverb Unit (AudioReverb by @Virsyn)
    2. MEDIUM DELAYS: Echo Unit ( Kozmonaut by Bram Bos)
    3. LONG DELAYS: Tape Looper (RE-1 by Kai Aras)
    4. REALLY LONG REPEATS: Looper App (Loopy HD by Michael's "A Tasty Pixel")

    The Bram Bos Kozmonaut app is a multi-tap Delay with a lot of presets. It can sound like a huge reverb effect or a slow running 4 head tape looping machine. Nice sound engine that doesn't over-color the results.

    4Pockets makes a MultiTap Delay App but only provides around 10 presets. It's also a very transparent "echo device" that can be configured to sound like a "chorus" effect.
    Almost any echo unit that allows for short echo settings can be configured to simulate a reverb unit.

    Kai Ara's has a tape delay product that intentionally colors the sound with tape saturation.

    Loopy HD included to finish the line of thought...

    With delay and reverb, you often want to sync it to your host bpm - it will sit in the mix better. If you're going for an effect to stand out from the mix, don't sync it. When "dialing in" a delay, try starting with no regen or feedback and only use the % mix and the time. Get that sounding good and then try using the regen/feedback to see how it sound to you.

    Transients in music are often important. Using compression is a good way to eat transients - be really careful with your attack settings (sometimes you want to reduce transients, so a short attack is good). When it comes to delay and reverb, the more transient you let through, the more it will sit in the mix and not "lose" your original sound (again, special effects are special) - this is where pre-delay comes in. In general, you want to try some different pre-delay lengths that fit your sound, but also can try some fit to bpm using something like this site

    Finally, also for a more natural sound and reverb/delays that will sit better in the mix, try rolling off (cutting) the low end and highest end from the sound before it hits the reverb or delay.

    Reverb and delay plugins or apps that have LP, HP and pre-delay settings are more convenient to use and can save CPU % by using only one thing instead of a chain.
