Developer apeSoft will be familiar to many iOS musicians through their various iOS music apps. These include iDensity, Stria and iPulsaret (all UK£5.99) plus the rather wonderful (and, to me, quite intimidating to program!) iVCS3 synth-meets-audio effect. If you have encountered any of these apps then you will know that apeSoft don’t really do ‘conventional’. Indeed, the iVCS3 – as a virtual recreation of a classic hardware synth from days gone by – is perhaps as conventional as it gets and, even then, they picked a very distinctive synth to model in software.
One of their other very interesting apps is apeFilter and I reviewed the app when it first appeared on the App Store and also posted when the app got a fairly substantial update in v.1.2 including an overhaul of the UI. At one level, apeFilter can be described as an EQ effect and, as every DAW app that you care to think of includes some EQ options, and there are a number of very decent iOS audio effects apps that cover EQ, you can be forgiven for perhaps thinking ‘so what?’ when reading about another EQ app.
However, do bear in mind apeSoft’s track record here; this is a developer that doesn’t really do ‘standard’ and, once you dig in, you soon realise that apeFilter is anything but another ‘me too!’ EQ option. Indeed, while I’m not sure I’m fully qualified to comment on some of the app’s more technical details (I have no idea what a Spectral Grid compiler is, for example), given that you can create an EQ curve with up to 36 peak filters, and that you get very precise control over the settings for each of those filters in terms of gain, frequency and bandwidth, I don’t think it would be too much of a stretch to label apeFilter as ‘most surgical EQ currently available for iOS’.
Anyway, apeSoft have released a further update yesterday and the latest version – v.1.3 – brings an update to the Audiobus SDK and a fix for the occasional issue when using the app via IAA.
At just UK£4.49, apeFilter packs a heck of a lot of features in for a very modest price. Anyway, check out the original apeFilter review for the full details as much of that still applies despite the new look. Perhaps not an essential tool for everyone but certainly a tool everyone could make good use of, both correctively and creatively.
