Multiband Audio Effect

FAC Bandit is a multiband audio effect that splits your audio signal into three independent frequency bands, each processed with its own effect and then recombined to create the final sound. Choose from a set of effects, including saturation, lo-fi degradation, ring modulation, delay, and reverb, and blend them precisely within each band. Two adjustable crossover points give you full control over which frequencies are affected, allowing you to shape your tone with precision.

By targeting each part of the spectrum separately, you can apply effects in ways that full-range processing simply cannot achieve. FAC Bandit is a powerful sound design tool for musicians who want to craft unique, personal, and exciting sounds, either subtly, without altering the original tone, or in a more creative way.

Following the diagram below, the input sound is split into three bands (Low, Mid, High), which are then recombined at the output:

Show/Hide Help Section

Band Parameters: Low, Mid, and High

• ①②③ Gain, sets the level of the band after the effect. This helps maintain tonal balance when the outputs are recombined
• ④⑤⑥ Mute/Solo, mute or solo the band to audition the effect on the frequency range. Can be used as a band killer
• ⑦⑧⑨ Fx, effect section. At the top there is a menu to select the effect, followed by three effect controls and a mix control to blend the dry signal with the wet signal. Check the section below to get a detailed overview of all the effects and their parameters

Other Parameters

• ⑩⑪⑫ Multi-Band Filter Low/High Bands crossover frequencies and slope (ranging from 6dB to 48dB)
• ⑬ Group control: Free or Linked. In linked mode, all band controls are linked; this includes crossover frequencies, gains, mixes, and FX parameters. The first knob/slider touched will control the others, and the changes are proportional to the original gesture
• ⑭ Dry, controls the level of the original signal
• ⑮ Wet, controls the level after the effect
• ⑯ Limiter, choose from brickwall, hard, or Off option
• ⑰ Preset button, preset manager (tap/long touch)
• ⑱ Info, review the app, Tip Jar to support FAC, documentation...

Saturation: Tube-like distortion

Parameters Drive, amount of saturation applied to the pre amplified signal PreGain, pre amplification of the drive section Pre/Post Filter, cutoff of the filter according to the model

Models Soft, soft clip before the drive then post LPF Hard, hard clip before the drive then post LPF BPF, pre BPF then soft clip before the drive BELL, pre BELL then soft clip before the drive

LOFI: Low resolution character of retro vintage samplers

Parameters Rate, down sampling rate. 1: none, 40: resampling SR of 1102hz Bit depth, resolution of each individual sample involved in the resampling process Filter, post LPF. Useful to reduce the artifacts generated by the decimation

Models Classic, classic quantization Dither, classic quantization with dithering noise applied Rizer, advanced quantization, works great down to 1 bit depth! Jitter , classic quantization with fixed down sampling jitter

Ring Modulator: Inharmonic content to your input signal, producing great percussion, metallic, or bell sounds

Parameters Note, sets the rate (MIDI note number) of the modulator. Use it as the root scale, great for jamming and creating tuned percussion Waveshape, shape of the modulator waveform: SIN/SQUARE Tone, LPF affecting the modulated signal, useful to reduce the artifacts generated by the process

Models RM 01, single ring modulator RM 02, dual ring modulator

Delay: Tempo based delay, providing depth and ambience

Parameters Feedback, the amount of altered signal returned to the input Division, the delay time as beat division Color, the width of the band-pass filter

Models: Ping Pong LR, echoes bouncing from left to right channel Inv Ping Pong, echoes bouncing from right to left channel Stereo Echo, classic echo. Keeps the stereo image untouched

Reverb: Recreate the sonic ambience of rooms and spaces

Parameters Size, the dimensions of the room or space Pre Delay, the time (as beat division) between the dry & wet signal Damp, sets the damping of the high frequencies

Models: Small, adds a sense of small space, less noticable Room, natural room with fast decay Hall, wider than the Room model with a longer decay Big, large space with medium diffusion and long decay Abyss, wider than the Big model with more diffusion

Linked Controls: In LINK mode, all band controls are linked, including crossover frequencies, gains, mixes, and FX parameters. The first knob or slider you touch controls the others, the changes are applied proportionally to the original gesture.

Multiple Outputs: Each band output is sent to a separate output bus, labeled Low, Mid, and High.

Host Routing: The plugin sends audio through these additional output buses, but routing is entirely handled by the host. It’s up to the host to receive these buses and provide a way for you to route them to mixer tracks or audio interface outputs. Check your host’s documentation for specific instructions on working with AUv3 multi-output plugins.

Always check your audio levels: In general, use the gains in parsimony, to avoid excessive levels that may damage your ears or your system. FAC Bandit shall not be liable for any loss or damage of whatever nature (direct, indirect, consequential, or other) to your materials (software, hardware, or other).

As with all FAC products, the interface has a unique sober look and provides a great user experience. The value of each knob can be monitored at any time. The knobs are very responsive, natural and follow a specific curve according to the parameter type.

Preset Management

FAC Bandit also comes with factory presets to provide you a source of inspiration to satisfy your needs in any situation you might require.

The preset button provides common management features: loading, organization, saving, importing and exporting. The left and right arrows allow fast navigation shortcuts among all the presets (factory + user), a short press on the center label provides a detailed list of all the available presets, select the one you want to work with. On the other hand a long touch (hold) provides contextual operations.
