Many pieces of studio hardware produce low-level electrical hum. Transformers can radiate at mains frequency. Power supplies can inject ripple at double mains. Grounding issues can create low-frequency interference between chassis. StudioHum is built around that controlled low-level hum layer, so the silence between tracks does not feel unnaturally empty.
StudioHum synthesises that hum from scratch. It is not a sample loop: it uses a harmonic oscillator bank locked to 50 or 60 Hz, with up to 16 harmonics shaped by one of three hum archetypes. Console Iron provides rounded even-harmonic emphasis. PSU Buzz adds the denser, grittier harmonic ladder of a power-supply-style source. Open Frame provides the more balanced, raw character of open EI-core transformer-style hum.
A drift engine gently modulates the fundamental frequency, keeping the hum moving slightly instead of sitting static. A ripple oscillator adds the 100/120 Hz power-supply pulse. A hash noise shaper adds mains-synchronous high-frequency grain inspired by magnetic and electrical switching behaviour.
Tone controls shape the harmonic profile. Brightness tilts the harmonic ladder brighter or darker. Warmth boosts the lower harmonics for a thicker, more present hum. Spread decorrelates the stereo image so the hum sits wide instead of centre-locked. Mismatch adds a subtle left/right gain difference for channel variation.
StudioHum reports 0 samples of latency. Repeatable by design: the same seed and settings recreate the same hum behaviour. Place it after the limiter when you want the hum layer to remain untouched by later dynamics, or on individual tracks when you want separate channel-by-channel hum.
StudioHum is offline-first. No internet connection required for activation or use. No plugin telemetry, no phone-home activation check, and no in-plugin account login. One local license file, one plugin.
Studio-hardware-style hum generator. Three archetypes, drift engine, reports 0 samples of latency.
Rounded and low-mid focused. Transformer-style hum with a clear even-harmonic bias: the second harmonic sits noticeably above the higher odd harmonics, giving it a large-console idle tone.
Edgy, aggressive. Dense harmonic ladder with odd harmonics present. Grittier and more forward than Console Iron — the sound of a power supply under load.
Raw and airy. Open EI-core transformer-style hum with a more balanced harmonic profile: the fundamental is relatively more present. Less polished, more exposed.
A synthesis engine built around mains-frequency hum: 50 Hz or 60 Hz, with the related harmonic stack generated live. Not a sample library, not a static drone. The hum, ripple, and hash components are synthesized in real time, so the noise floor sits around the places electrical noise actually appears.
Three distinct hum voicings. Console Iron focuses on transformer-style low-order harmonic body. PSU Buzz pushes stronger harmonics, rectifier ripple, and switching texture. Open Frame keeps the fundamental more exposed with a less transformer-weighted harmonic shape.
Drift adds slow frequency and stereo movement so the hum never sits perfectly still. Ripple adds rectifier-style 100/120 Hz movement. Hash adds filtered switching grain shaped by the mains cycle. Three layers that turn a static hum into living noise-floor texture.
A real-time spectrum view shows four traces simultaneously: the input signal, the hum being added, the resulting output, and the difference between input and output. See what StudioHum is adding to the source, and where it sits in the spectrum.
