Beat Twirl Turns iPhone, iPad Into A Beat-Slicing Workstation

Beat Twirl

Beat Twirl is a new “beat slicer” app for the iPhone, iPod touch or iPad.

The app lets you analyze existing sounds and detect their rhythm with its note onset algorithms. With Beat Twirl you can work with drum loops and rhythm patterns, enhancing them with additional percussion sound, or create new patterns.

With Beat Twirl you can:

  • Change the tempo (time) of drum loops without changing the pitch.
  • Analyze percussion patterns and find the underlying timing.
  • Mix-in additional percussion sounds, or replace the original sounds
  • Export single beats from a sound file.

Features:

  • Import audio from your ipod library, using iTunes file sharing or using audio copy/paste from supporting applications.
  • Record using an external mic or the built in mic.
  • Universal app. UI designed iPhone, iPod touch and iPad. Supports retina displays.
  • Two spectrum based note onset detection algorithms.
  • Manual slicing capabilities on top of the automated algorithm.
  • Mix in percussion beats from a library of 300 samples.
  • Export audio as wav, caf or aac. Export using audio copy, iTunes files sharing or email.

Suggested uses:

  • You can record yourself singing or clapping a rhythm, than add percussion instruments to the rhythm you created.
  • You can extract a rhythmic/percussive section from a song and convert it to a loop you can play along with at different tempos.
  • Mix-in percussion instruments to a song to enhance its’ rhythm.
  • Extract beat samples from a song for use with a beat sequencer.

Beat Twirl is $12.99 in the App Store.

  1. WILL YOU STOP WITH THIS APPLE SHIT ALREADY !!! I GET THAT APPLE IS PAYING YOU TO DO IT; BUT AT LEAST CHANGE THE NAME FROM SYNTHOPIA TO APLLAND!!! IT WOULD BE MORE APPROPRIATE,… AT LEAST BY LOOKING AT YOUR RECENT POSTS.

    there,…. i got it out,… i feel much better tahnks πŸ™‚

  2. I see two apps on the page. This one, and the MIDI iPhone controller. Sure, this one is kind of lame, but the MIDI controller fits in context of this site.

    Also the iMS-20 is rad. Don't hate on the iPad too much.

  3. I don't really understand why there's so much hate on the Apple stuff; it seems to me that it would be prudent for any person even remotely interested in electronic music production to have an iPad by now, if ONLY to use it as a multitouch control surface for some other fancier toy…

    It's incredibly useful and quite cheap compared to most music hardware I've seen; yeah, it's not specific and it's only as good as its software, but there's a lot of software out there and that's why it's good to see stuff reviewed/previewed here.

    888 GREAT POST WOULD READ AGAIN

  5. I second that.

    As a semi pro musician, I see no use in any of the music apps that are available APART from the odd midi control type doo daas which look like they would be fun. Would I pay £500 to be able to have non tactile feedback of midi parameters…no definately not.

    I see the iPad as just a basic computer with a touchscreen. I would never think of using apps on it to make music when I have a top spec Mac as the central hub off all my music, the software and the hardware.

    The apple fan boys really REALLY do my head in. Especially the ones with no life that queue up over night to buy the latest Apple product….must consume…MUST CONSUME NEXT FAD…… etc πŸ™‚

    Check this out – Charlie Brooker on the iPad 2: "The device that changed everything…starting with the way [email protected] nkers draw attention to themselves!"

  11. The tablet ecosystem comprises one of the more interesting developments in the world of music technology. Sure, it's mostly consumer-oriented so far but it will catch up to us.

    I don't own an iPad but I am interested to see what's available for it in case I do make that jump. Keep these posts coming.

  12. I agree with the fact there is often too much ads for apple.

    I had mine , for free.

    Guess what ?

    In music software, like :

    Ims20, Electribe, Nlog Pro; BeatMaker…

    You can do music that sounds 'pro', and it costs me much much less than having to buy this stuff for real or on pc.

    Thanks to god, I can connect a midi keyboard (no name) and it works great.

    You can have a 'portable' music production with you.

    Have some ideas, start on Ipad. Come home or in studio and finish it.

    So stop, sayin it is shit.

    The future is here. Just don't buy fool apps like Garage band * smile, if you are a pro.

    Don't miss the train.

  13. I remember similar hate posts when digital cameras first start to show up, and those old timers said they wont even come close.

  14. Stumbled across this from 2011 – I wonder if the blinkered folks above still feel the same way now that things have matured a bit?

    I’m definitely very pro-iPad music stuff – love it!
