What it does

DeeSpeaker is a free monitor simulator from Dotec-Audio for mixing on headphones. The developer says it "simulates near-field speaker" placement at 45 degrees and 1 m from the listener.

Speaker placement: a fixed virtual pair of near-field monitors at a 45-degree angle, 1 m away.
Processing: filter and phase processing recreate the sound of real monitors in a good room, which Bedroom Producers Blog describes as emulating the cross-feed and frequency response of the speakers.
Room: adds synthesised studio reflections.
Controls: essentially none; Bedroom Producers Blog found a single parameter that works as an on/off switch.
Light on CPU: the same review found it very stable and easy on the CPU.
Recent updates: 1.1.0 brought stability improvements and a notification function, and 1.1.1 improved graphics performance.

The current version is 1.1.1 (13 January 2026), and it is free.

When to use it

DeeSpeaker is the simplest way to hear a headphone mix with a speaker-like stereo image: put it on the master bus, switch it on and listen. Unlike REFERENCE 3 or Metric AB, it does not compare your mix with reference tracks; it changes how you hear your own mix. Compared with paid headphone tools such as dSONIQ Realphones or Sonarworks SoundID Reference, it has no headphone correction profiles and no choice of rooms or speakers, and nothing to adjust. In return it is free and costs almost no CPU. It should be removed or bypassed before export, since it colours the master output.

Best for: checking stereo width and panning on headphones, mixing while travelling, and quick second opinions on a headphone mix.
Genres: any.
Look elsewhere if: you want headphone correction or adjustable rooms and speakers; Realphones or SoundID Reference do more.
Tip: use it as a check on headphones, not a replacement for monitors; Bedroom Producers Blog still recommends real speakers for judging stereo width.

What producers say

Listeners find it moves a headphone mix closer to speakers, though not all the way.

Bedroom Producers Blog (Tomislav Zlatic, 2016) said it "does indeed alter the stereo image" of headphones in a positive way, but it "definitely doesn't sound as natural" as real speakers.
KVR user (2016) couldn't confirm it behaves like monitors but found it "really closer to 'truth' with it".
Criticisms: with one on/off control there is nothing to tune to your headphones or taste.
