iOS App of the Week There are dozens of equalisers, visualisers and similar audio apps available for iOS devices, but I have to tip my hat to Reg reader Danny Mann for bringing EQu to my attention, as it’s one of the best audio apps I’ve seen of late.

EQu: tap and drag to change the equalisation curve

EQu is a fairly straightforward equaliser, yet it’s easy to use and produces real improvements in sound quality – even when listening to music on the tinny little internal speakers that are built into the iPhone and iPad.

The app allows you to browse your music by album, artist or playlist, and then presents you with a detailed equaliser display that provides precise control over individual frequency bands.

Or apply a preset

Initially, the app plays unmodified sound using its ‘Flat’ preset, which displays a simple flat line running across the equaliser display. Tapping on this line turns it into a curve that you can manipulate in order to modify the sound output.

Bomb the bass

Further taps on the curve create additional node points that allow you to focus on specific frequency bands, giving you really fine control over your sound.

EQu taps straight into your iDevice's music library

There are ten built-in presets to help you get started. Most of these need a bit of additional fine-tuning to get decent results, but the ‘small speaker’ preset worked well when listening to music on my iPad’s internal speaker.

You can also save your own custom presets, perhaps having different presets for use with headphones and larger speaker systems.

Create your own presets

The app does need a better ‘Undo’ command – it’d be easier to fine-tune your settings if you could step back and undo or redo your most recent tweaks – and it can’t play DRM-protected music tracks, if you have any of these left.

However, EQu has already changed the way that I use my iPad, as I’m now happy to listen to music using just the iPad’s own internal speaker – and that surely is the mark of a good app. ®
