• 3-Band multi effects processor • Each band provides its own effect with mix blending control • Comes with built-in effects: Saturator, Lofi and Ring Modulator • Extendable via In-App purchase in Bandit store: Delay and Reverb • Frequency isolator equaliser (DJ style filter) • Two adjustable crossover points for low and high bands with slope up to 48dB • Separate Dry/Wet output controls • Suitable for any situation, going from subtle to drastic change • Multi-outs support, route each band to separate channels in your DAW • Advanced Responsive Design, portrait and landscape views • AuV3 for iOS (iPad/iPhone) FAC Bandit is a multiband audio effect that splits the audio signal into three bands of frequencies according two adjustable crossover points. Each band is processed independently by its own effect processor and the outputs are then recombined to produce the final effect. Each frequency range is altered with different effects and settings that won't sound the same if applied to the full frequency range. As you have probably realized, FAC Bandit is a wonderful and powerful sound design tool for designers who want to sculpt new personal, exciting and outstanding sounds. Either in a subtle way, without compromising the original tone, or in a more drastic way. - AuV3 and Standalone App - To use multiple outputs, you need a host able to provide additional output busses to the AuV3 plug-in The documentation is available at fredantoncorvest.com/FAC_Bandit.html

TfxEcho is an echo effect AudioUnit Extension plugin. It uses delay lines which are inspired by BBD (bucket brigade device). BBD is used in various analog delay unit and is known for its warm and dark sound. The delay line uses fixed length buffer and an artificial clock to sample input signal in variable sampling rate. When the delay time is changed, the delay line can produce pitch change effect which is similar to the behavior of the BBD based analog delay unit. The delay line is inspired by BBD, but it is not emulation of the any particular BBD. Unlike the typical BBD based delay unit, frequency range of the delay line is not limited. The delay line is capable to capture signal in higher frequency up to about 22KHz. Features AudioUnit Extension - Delay Time: From 20 ms to 1200 ms - Feedback: From 0 % to 100 % - Adjustable lowpass filter and high-pass filter. - Modulation rate: From 0.01 Hz to 10 Hz - Modulation width: From 0 ms to +/- 10 ms - Delay time can be synced to tempo provided by the host application. Host Application Host application uses system audio input as an audio source and processed audio signal is routed to the system audio output.
