Bar Visualizer Settings for Suno Genres: Lofi, Jazz, Ambient, EDM, Pop
If you generate music in several styles, one visualizer setting rarely suits all of it. A lofi beat with a soft top end and a loud EDM track behave very differently on a spectrum display: one leaves the right half of the bars nearly flat, the other pins every bar to the ceiling. This guide explains what each reaction control does, then gives starting values for five styles that are common in Suno playlists.
All reaction controls apply live during preview. Analysis runs once when you load a track, and these sliders only change how stored data is turned into bar heights, so you can drag them while the song plays and see the result immediately. Export uses exactly the same calculation as the preview.
The three presets
The presets are a quick way to set all five reaction sliders at once:
| Preset | High-frequency boost | Sensitivity | Floor | Smoothing | Decay |
|---|---|---|---|---|---|
| Calm | 2.0 | +4 | −90 | 0.75 | 0.82 |
| Default | 3.5 | +8 | −78 | 0.45 | 0.62 |
| Punchy | 4.2 | +14 | −66 | 0.24 | 0.55 |
Pick the nearest preset, then adjust individual sliders. Changing a slider after picking a preset does not reset the others.
What each control does
Sensitivity (−6 to +30 dB, default +8)
Sensitivity adds a fixed number of decibels to every bar before it is scaled to the screen. Raising it makes all bars taller; lowering it makes all bars shorter. It does not change the shape of the spectrum, only its overall height.
Use it to fix a track that is mastered quieter or louder than usual. If the bars rarely pass the halfway mark, raise Sensitivity. If most bars sit at the top for the whole chorus, lower it.
Floor (−110 to −45 dB, default −78)
Floor sets the level that maps to a bar height of zero. The top of the scale sits at a reference level of −18 dB, so the visible range normally runs from Floor up to about −18 dB. Very loud tracks shift this range up automatically so the bars keep their shape instead of piling up at the top.
- Raising Floor (toward −45) cuts off quiet content. Bars drop to zero more often, and the movement looks sharper and more rhythmic. It also narrows the range, so the same change in loudness produces a bigger change in bar height.
- Lowering Floor (toward −110) lets quiet details show. Bars rarely reach zero, and the display looks fuller but calmer.
Floor and Sensitivity interact. Raising both at the same time gives a high-contrast look: loud hits jump, quiet passages disappear.
Smoothing (0.00 to 0.92, default 0.45)
Smoothing blends each frame’s spectrum with the previous frame’s. At 0 every frame stands alone, so bars twitch on every transient. At 0.92 each new frame contributes only 8% to the result, so bars glide.
Smoothing is applied per frequency bin before bars are formed, and it also sets how quickly each bar climbs toward a louder value. A kick drum will rise more slowly with high smoothing, not just fall more slowly. Even at 0, a bar does not leap all the way to a new value in a single frame; that small cushion is what keeps noisy content such as hi-hats from making the bars flicker up and down every frame.
Decay (0.00 to 0.95, default 0.62)
Decay controls how fast a bar falls after a peak. When the level drops a lot, the bar falls no faster than its previous height multiplied by Decay. Small dips and small rises are eased in both directions, so a bar does not shiver when the sound wobbles slightly; only big changes such as a kick get the full speed. Decay never slows a rise; that is set by Smoothing.
This is different from Smoothing. A low Smoothing with a high Decay gives fast, sharp hits that fall slowly, which reads as “punchy but not nervous”. A high Smoothing with a low Decay looks soft on the way up and abrupt on the way down, which is rarely what you want.
Smoothing and Decay are defined in time, not per frame, so the same values look the same at 24, 30 and 60 fps. Decay 0.62 halves a bar’s height in about 48 ms; Decay 0.82 takes about 116 ms.
High-frequency boost (0.0 to 8.0 dB per octave, default 3.5)
Music carries much more energy in the bass than in the treble. Without correction, the left side of the display towers and the right side barely moves, which looks like a staircase. High-frequency boost tilts the spectrum: the lowest bar gets no boost, and each octave higher gets the slider value in extra decibels. The bars cover about nine octaves (30 Hz to 16 kHz), so at the default 3.5 the highest bar receives roughly 30 dB more than the lowest.
Raise it if the right side of the display stays flat. Lower it if hi-hats and cymbals dominate and the bass bars look weak.
Starting values for common Suno genres
The table gives a starting point for each style. Every song differs, so treat these as a place to begin tuning, not as final values.
| Genre | Start from | High-frequency boost | Sensitivity | Floor | Smoothing | Decay |
|---|---|---|---|---|---|---|
| Lofi | Calm | 3.5–4.5 | +6 to +10 | −85 to −80 | 0.60–0.75 | 0.75–0.85 |
| Jazz | Default | 3.5–4.5 | +8 to +12 | −85 to −80 | 0.45–0.60 | 0.65–0.75 |
| Ambient | Calm | 2.5–3.5 | +10 to +16 | −95 to −88 | 0.75–0.90 | 0.85–0.92 |
| EDM | Punchy | 3.8–4.8 | +4 to +10 | −70 to −62 | 0.20–0.30 | 0.50–0.60 |
| Pop | Default | 3.0–4.0 | +6 to +10 | −76 to −70 | 0.30–0.45 | 0.55–0.65 |
Suno is a separate product; SongToBars is not affiliated with Suno. The genre names here describe musical styles, not settings inside Suno.
Lofi
Lofi often has rolled-off highs (frequently on purpose), steady drum loops, and warm keys. The risk is a display whose right third never moves, so it needs more tilt than the Calm preset’s 2.0. Keep Floor low enough that soft keys still register; if vinyl crackle or tape hiss keeps every bar hovering above zero between notes, raise Floor toward −78.
Look: 32–40 bars, Bar width 60–70%, Corner radius 6–10, a warm color (amber, off-white), Bottom layout.
Jazz
Jazz has a wide dynamic range: quiet piano or bass passages can sit far below the full-band sections. Play the quietest and loudest sections before exporting. If the quiet parts look dead, lower Floor. If the loud parts pin the bars, lower Sensitivity rather than raising Floor, so the quiet passages survive.
Look: 40–48 bars, enough resolution to see a walking bass line move separately from the piano. Mirror layout, with its faint reflection under the bars, suits a calm composition placed mid-frame.
Ambient
Ambient pads and drones change slowly and often sit at a low level with few transients. With normal settings the bars barely move. Raise Sensitivity and lower Floor so the sustained sound fills the display, and use high Smoothing and Decay so the bars swell and fade instead of flickering. Look: 24–32 bars, Bar width 50–60%, large Corner radius, a pale or cool color. Center layout reads as a soft waveform.
EDM
Loud, dense masters with heavy sub-bass and bright synths. The risk is the opposite of lofi: every bar sits at the top during drops. Lower Sensitivity until only kicks and peaks reach the ceiling, and raise Floor so breakdowns drop to near zero and the drops stand out.
Look: 48–64 bars, Bar width 70–85%, Corner radius 0–3 for a hard edge. Center layout works behind a logo or title.
Pop
Pop sits between jazz and EDM: a loud, polished mix with vocals in the middle bars and a clear beat. The Default preset is close already. Raise Floor a little so verses and choruses look different, and keep Smoothing moderate so the vocal range does not jitter.
Look: 40–48 bars, Bar width 65–75%, Corner radius 3–6, a color taken from the song’s cover art. Bottom or Mirror layout.
Playlists that mix genres
The visualizer applies one set of reaction settings to the whole combined export. If your playlist moves from ambient to EDM, export each block of similar songs separately with its own settings and join the clips in your editor.
A five-minute tuning routine
- Pick the nearest preset.
- Play the loudest 10 seconds. Adjust Sensitivity until only the strongest hits reach the top.
- Play the quietest 10 seconds. Adjust Floor until the bars still move but do not hover above zero during silence.
- Look at the shape. If the left side towers, raise High-frequency boost; if the right side dominates, lower it.
- Adjust Smoothing and Decay last, by feel.
Use the arrow keys to jump 10 seconds back or forward and the space bar to play or pause while you tune.
