The Aura Rack — A Live Multi-Effects Processor by Victory Musical Instruments
A Complete Effects Rack.
For the Solo Performer.
The Aura Rack is a free, browser-based multi-effects processor built for musicians who perform alone. Whether you sing, play saxophone, trumpet, or an acoustic instrument, it gives you a full professional signal chain — equalization, compression, tube warmth, chorus, delay, and convolution reverb — running live from a laptop or iPad. No installation, no downloads. Connect a microphone or audio interface and perform.
Solo vocalists — shape your tone, even out your dynamics, and add room, hall, or chapel reverb so your voice fills any venue.
Saxophone, trumpet, and wind players — give your horn presence, warmth, and space when you perform without a band behind you.
Acoustic and worship musicians — a clean, professional signal chain for intimate rooms and full stages alike.
The Aura Rack processes a live input signal, so you'll need a way to get your voice or instrument into your device — typically a microphone and a USB audio interface, plus the right cables. The quality of that input chain directly shapes your sound. Explore microphones, audio interfaces, and cabling at Victory Musical Instruments to build the setup that fits your performance.
EQ (Equalization)
Turning specific frequency ranges up or down to shape tone — brightness, warmth, clarity.
High-Pass Filter (Low Cut)
Removes everything below a chosen frequency. Cleans up rumble, stage thump, and microphone handling noise.
Shelf & Bell Filters
A shelf lifts or lowers everything past a point; a bell boosts or cuts a focused hump around one frequency.
Q
The width of a bell filter. Low Q is wide and gentle; high Q is narrow and surgical.
Compression
Automatically reduces the volume of loud moments so your overall level stays even and controlled.
Threshold & Ratio
Threshold is the level where compression begins; ratio is how firmly it acts once crossed.
Attack & Release
How fast the compressor reacts when sound gets loud, and how quickly it lets go afterward.
Saturation / Tube Warmth
Gentle, musical distortion that rounds off peaks and adds harmonic richness — the warmth of vintage analog gear.
Chorus
Layers slightly delayed, slowly-wavering copies of a sound to make it thicker, wider, and shimmering.
Delay & Feedback
Delay repeats your sound after a set time; feedback controls how many repeats trail off before fading.
Tap Tempo
Set the delay time by tapping a button in rhythm, so echoes land in time with your song.
Ducking
Automatically lowers an effect while you sing so it doesn't muddy your words, then lets it return between phrases.
Reverb
The sound of a physical space — the natural decay you hear in a room, hall, chapel, or cathedral.
Impulse Response (IR)
A recording of how a real space responds to sound, used to recreate that exact acoustic space.
Pre-Delay
A short gap before the reverb begins, which keeps your voice clear and upfront before the space blooms.
Wet / Dry Mix
The balance between your unprocessed sound (dry) and the effect (wet).
Master Bypass
Instantly routes your voice clean and dry, skipping every effect while the rig stays live and audible.
Limiter
A safety processor that stops the signal exceeding a maximum level, protecting your speakers from clipping.
