Short description

AURORA is a free dynamic parametric EQ from 13x.audio. Shape a mix with up to 24 bands, per-band dynamics, mid/side control and three phase modes. Its Smart Ops assistant helps match references, tame resonances and unmask tracks, leaving every change editable. No account or licence key is required.

Long description

AURORA is a free dynamic parametric EQ from 13x.audio for mixing, mastering and everyday cleanup. Its live spectrum lets producers see what they hear and shape it with up to 24 editable bands. Per-band dynamics can respond to problem frequencies as they appear, while mid/side and left/right placement provide control over the stereo image.

The built-in Smart Ops assistant can match a reference spectrum, find resonances, de-ess, bracket a signal with high- and low-cut filters, and unmask one track against another. Each action produces bands that remain editable, keeping the final decisions with the producer.

Zero-latency, Natural and Linear phase modes cover different tracking and mixing needs. Clean, Subtle and Warm character options provide additional tonal choices. The plugin works offline with no account, licence key or trial limit. Download the format for your platform and load it in a compatible DAW; platform requirements are listed in the fact sheet below.

What’s new in 1.6.1

# Aurora 1.6.1 — no more loud peaks when you change a filter during playback

An urgent fix, thanks to a user who sent a screen recording. Please update.

- **Changing the slope of a Low Cut or High Cut no longer causes loud peaks.** Switching the
  slope while your track played, for example from 24 to 30 dB/oct, could make Aurora's
  output jump to far above the level of your music for a moment. We measured peaks up to
  +25 dBFS from a signal at -12 dBFS, loud enough to hurt speakers and ears. Aurora 1.5
  behaved the same way. Now the new slope fades in smoothly once it is ready, a
  fraction of a second after you pick it.
- **Other changes during playback are smooth now, too.** The same kind of jump could happen,
  less strongly, when you:
  - changed a band's filter type or its stereo placement (Stereo, Left, Right, Mid, Side);
  - switched between Zero Latency or Natural Phase and Linear Phase;
  - changed a frequency in one big step, for example by typing a value, loading a preset or
    switching A/B;
  - changed the Character setting (Clean, Subtle, Warm), also through a preset or A/B.

  All of these now fade over to the new setting. Switching a band on or off fades too.
- **Full screen opens in front of FL Studio's plug-in window.** On a Mac, the full-screen
  spectrum could open behind FL Studio's floating plug-in window. It now opens in front.
- **Safety net.** If a broken value ever arrives from the host or appears inside Aurora,
  it is silenced instead of being passed on, and Aurora carries on playing normally.

**Good to know:** Some changes take effect a moment after you make them, because Aurora
lets the new setting settle before it fades it in. That is usually a few hundredths of a
second, and up to about a second for a Brickwall cut at a very low frequency.

Your sound doesn't change: with settings that stay as they are, Aurora 1.6.1 sounds
exactly like 1.6.0. Projects and presets load unchanged.
