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.
