Here, we review the neuroscience literature to examine whether neural processes associated with semantics are also involved in emotion.

But sadly not DropBox.What role does language play in emotion? Behavioral research shows that emotion words such as “anger” and “fear” alter emotion experience, but questions still remain about mechanism. You can export sounds as *.wav files and export to iTunes or SoundCloud. I would probably prefer the iRig for vocals (it just feels better) but the Mickey is great if you are using Harmony Voice for other types of audio. I tried with both the iRig Mic and the Blue Mikey and it sounded spectacular. Whilst you can sing via the built-in microphone it’s noticeably better using a dedicated bit of kit. I loaded a scratch track I’m made in GarageBand and then sung over the top, before Audio pasting the recording back into GarageBand (iPads are clearly no longer toys). Sticking with the karaoke theme, you can load a background track from your iTunes library and sing along. The room simulation on the reverb alone is pretty impressive. There are only a few built-in effects – Reverb, Chorus and Delay but they sparsity is offset by the quality. Some of the more extreme female sounds tend to get a little chipmunky but at the moderate end of the scale it’s not hard to imagine there’s a lady or Barry White-a-like in the room with you. There’s also a gender dial so you can adjust your voice to sound more “male” or “female” according to preference. There’s a realtime visual intonation-display gives you feedback of the tunes you sing – much like when you play Singstar or any similar karaoke game. If you wanted to add some atmosphere to your doom metal it’s definitely worth investigating. Whilst singing you can fiddle with key notes and scale for harmonisation and pitch correction – so you can do some pretty interesting chanting or drone effects.

You just have to hit the base note and Harmony Voice will add the appropriate chords. If you’re not a keyboard player you can let Harmony Voice play chords automatically. You can use a CoreMIDI compatible Interface to control Harmony Voice with a MIDI Keyboard. The best scenario is to break out a 30-pin to USB connector (will there be a Lightening to USB connector some day as daisy-chaining a lightning to 30 pin to usb to get a keyboard working is pretty silly) and attach a USB keyboard. This is impossibly small on the iPhone but serviceable on the iPad. As you sing Harmony voice adds up to four voices depending on what you play on the keyboard. There’s a built-in keyboard so as you sing, Harmony Voice can sing along with you, automatically enriching the sound of your voice with … well harmony. Much more than a just a toy (although it is fun to play with), Harmony Voice Four part realtime Harmoniser / Pitch corrector that enables you to become a one man/woman barbershop quartet (a barbershop singlet?). Harmony Voice is a pitch shifter and harmoniser with a host of “professional features” including automatic tuning correction. Well they weren’t content to rest on their laurels and have just released Harmony Voice a harmoniser for iOS devices. You might remember VirSyn from the pretty amazing iVoxel, which brought an amazing combination of a voice optimised synthesiser and a vocoder to your pocket.
