ChannelStrip is, as its name implies, a channel strip app and AUv3 plugin. With a gate, equalizer, and compressor, ChannelStrip can provide a solid and easy-to-use channel control for your iOS mixing needs. GATE: The gate is of our own design, and very smooth. With envelope that vary from nearly instantaneous to ludicrously long, you can use it for both basic noise control and more extreme tonal shaping. EQUALIZER: Modeled on the PEV, a famous German "cartridge" equalizer, the EQ in ChannelStrip is super useful for basic tone shaping. A very smooth and forgiving general-purpose EQ. COMPRESSOR: The compressor in ChannelStrip is, at its heart, our Rough Rider model. We removed all the filtering from Rough Rider to make it cleaner, and changed the times to be more appropriate to general mixing duties. I/O: ChannelStrip has positive gain on both the input and output, to get your levels right. It also has a bit of a personality on the output stage if you drive it hard (with either or both the input and output gains). Nominally very clean, it picks up a bit of dirt with high levels just like a hardware console. Along with that, both mute (which mutes the input entirely) and bypass (which sends the inputs right to the outputs without passing the DSP stages) are available as automatable parameters. In short, ChannelStrip is a general utility mixing tool, with a bit of character and a lot of usefulness. We _strongly_ recommend you use the AUv3 version. The standalone is provided as a courtesy, but ChannelStrip is designed as an AUv3 plugin, and prefers to be hosted in a DAW or modular host like GarageBand, AUM, Cubasis, nanoStudio, etc.

"LO‑FI‑AF is a very capable lo‑fi toolkit capable of surgically targeted destruction and it could easily find applications in just about any musical genre" -SoundOnSound Unfiltered Audio's lo-fi-af is now available on iOS as a Standalone app or AUv3 plugin! lo-fi-af takes your sound on a journey of artifacts and noise throughout recorded history, from tape warbles and vinyl noise to MP3 chirps and cell phone speaker chatter. lo-fi-af's many sections and versatile algorithms can place your sound in a different decade, or give it a thoroughly modern spin through compound processing. The first section is a convolution reverb preloaded with impulse responses from broken microphones, toy speakers, cell phones, and more. With this section alone, you can place your sound into an entirely different space. The Spectral section then splits your sound into thousands of frequencies before reconstructing it with a twist. Here you can reproduce the sound of a pirated MP3 or pitch shift your signal with clean perfection. Your signal then takes a trip through the digital section. All sorts of hazards are present here, from a skipping CD stutter effect to a multimode bitcrusher. Finally, the rich, colorful analog section adds that vibe that you crave. A maximizer, a tape saturator, a noise generator, an analog-style filter, a pitch warbler, and a radio demodulator all work together in harmony to toss your sound into the past. But wait! That's only one possible signal chain. The Convolution, Spectral, Digital, and Analog sections can be completely rearranged in any order. Dozens of presets will get your started on your sound warping adventure. As an AUv3 plugin, lo-fi-af has been tested to work perfectly with Garageband, Drambo, AUM, Cubasis, Beatmaker, Nanostudio, apeMatrix, Loopy Pro, and more! Additionally, with its clear layout and smart resizing, lo-fi-af can be used on tablets and phones with ease. (Note for Drambo users: Drambo does not yet have automatic Plugin Delay Compensation for managing plugins with latency. As a result, tracks with lo-fi-af will not line up properly with other tracks. An upcoming patch for Drambo will add this feature in.)
