ToneBoosters Equalizer is a top-quality, professional, dynamic equalizer AUv3 plug-in with an unrivalled workflow, warm, non-linear filters and a gorgeous, functional user interface. The ToneBoosters Equalizer app captures the microphone (or external sound card) input and processes the signals in real time. To use it as a plug-in, use an AUv3-compatible host app such as Steinberg Cubasis, Apple Garageband, Audio Evolution Mobile Studio, Auria, AUM, or others. ToneBoosters Equalizer will appear in the list of Audio Unit extensions for effect plug-ins. Key features: - Mastering grade, professional equalizer - Integrated spectrum analyser and dynamics analyser - The same professional sound as the acclaimed desktop version - Up to 16 filter sections with a very wide range of filter types - Run each section in dynamic or static mode - Run each section with digital purity or with analog character and non-linearities - Oversampling and anti-aliasing modes to further improve sound quality - Use Artificial Intelligence (AI) for content-dependent equalisation suggestions - Audition mode to easily identify problematic frequency areas - Automatic level make up function for every section - Zero latency mode for live operation - Lasso function to select and move multiple filters simultaneously - Piano display to select musical note frequencies - Output VU meters showing peak and RMS levels simultaneously - Undo/redo, and A/B comparison - Color themes for the user interface - Adjustable colours for every filter section - Mid, side, left, right processing for stereo input for each section - Max screen support in Garageband - Optimised for iPad and compatible with iPhone and iPod Touch - Efficient, low CPU usage What you should know: - Licenses acquired for this platform are not compatible with other platforms. - Audio Unit (AUv3) extensions require an iPad mini 2, iPad 4 or later models.

RRS CL1 AUv3 plug-in — comes as time-limited Demo-version for you to try. It gives you 5 minutes of Free play time. (You can reload the CL1 AUv3 plug-in as many times as you want, thereby you get the Demo period again and again.) Unlimited version of CL1 AUv3 plug-in comes as In-App Purchase. CL1 is stereo and mono audio signal dynamic range compressor. CL1 compressor has distinctive sound allowing its usage not only for technical purpose of dynamic range compression but also for artistic sound coloration, which happens due to usage of saturation with even harmonics, dithering that gives effect of «air» and oversampling with non-linear phase response that gives effect of «depth». CL1 compressor besides main dynamic range compression module also contains limiting module («limiter»), which allows controlling peaks passing through the compressor, mid-range equalizer module doing ISO-226 curves equalization and input signal or gain reduction VU-meter with lamp indicator for limiter operation control. CL1 compressor has adjustable high-pass filter for side-chain signal, also supports «parallel» compression and M/S operational mode. FEATURES: • Two different attack modes: «fast» and «slow»; • Softness of compressor characteristics control; • 6 operation modes: double mono, mono with external side-chain signal, mid channel, side channel, M/S, linked stereo; • Mid-range equalizer and Side-chain signal high-pass filter; • Pre- or Post-Limiter; • Attack and Release times multiplier; • Internal Dithering; • Parallel compression; • 8x oversampling and 64-bit floating point processing; • External Side-chain. • A/B comparison; • 2x/4x/8x Upsampling; • Macro controllers; • Built-in Gain Match; • Scalable GUI. ATTACK MODE: • In «Fast» mode when control signal reaches Threshold the compressor immediately and very fast starts to lower the signal level slowing down by exponential law; • In «Slow» mode the compressor in the same situation starts gain reduction very slowly thus most attack of the signal passes through. MID SCOOP: • The built-in mid-frequencies equalizer is based on mid-frequency range equal loudness curves design and can be used as another tool to position instruments, with ability to highlight backside elements or to add a bit density to frontal elements and move them back at the same time. CL1 developed on the basis of «МОЛОТ» compressor by Vladislav Goncharov. To use CL1 as a plug-in, you need an AUv3-compatible host app like GarageBand, Auria, AUM, Cubasis and more — CL1 will appear in the list of Audio Unit extensions for effect plug-ins in the host app.
