Shape the sound with EQ, room and width

The Sound tab works on everything the room plays — after each scene's own mix, before your speakers. It is the same for every scene in the playlist, so a change here keeps the whole room consistent.

Start from a preset

At the top are five buttons: Flat, Warm, Bright, Far away and Small room. Each one sets every effect at once:

• Warm lifts the lows a little, lowers the highs and adds a light living-room ambience.
• Bright cuts rumble below 60 Hz and lifts the highs.
• Far away removes lows and highs and adds a large hall with a narrower stereo image — sounds lose high frequencies and gain reverberation with distance.
• Small room adds a short room.

The pressed button shows which preset is active. As soon as you move a slider, no button is pressed any more. Ctrl+Z brings the previous settings back.

Read the curve

Under Equalizer a chart shows the combined frequency response of all filters from 20 Hz to 20 kHz. The line at 0 is "unchanged". The curve is computed with exactly the formulas your browser uses for its filters (the Audio EQ Cookbook biquads), so what you see is what you hear.

The eight bands

The sliders 63 Hz to 8 kHz raise or lower one octave each by up to 12 dB. Some ideas:

• Rumble from brown noise feels heavy: lower 63 Hz and 125 Hz by 3 dB.
• Rain sounds harsh: lower 4 kHz and 8 kHz.
• Speech-like murmur distracts you: lower 1 kHz and 2 kHz, where voices carry most of their information.

Low cut and high cut

Low cut removes everything below the chosen frequency with a steep slope; High cut softens everything above it. At Off they do (almost) nothing. A high cut at 3 to 4 kHz makes any ambience sound distant and calm.

Room and width

Room places the whole playlist in a space: small room, living room, studio, concert hall, cathedral, cave or open forest. Room amount sets how much of the room you hear. These are the same reverb presets Soundscape Atlas uses for its scenes.

Stereo width at 100 % leaves the stereo image as it is. Lower values narrow it (0 % is mono — useful with one earbud), higher values widen it.

Volume and limiter

Master volume (also in the player at the bottom) changes the level of the whole room. Gentle limiter (keeps peaks soft) rounds off peaks that would otherwise clip. It is a soft clipper, not a broadcast limiter; if you hear it working, lower the volume instead.

Same sound in the WAV file

File → Render playlist to WAV… runs the very same chain on your device, and the focusroom-playlist-render tool does it on the server for generated scenes — the files are identical for the same room. See Soundscape scenes, WAV and sharing.
