1 · Why this exists
Audio files from different sources are mastered differently. A Suno-AI track might sit at -8 dBFS, a live recording of a singing bowl at -22 dBFS. In the mix one is too loud, the other almost inaudible.
That's what the per-track level in dB is meant for; it doesn't change the original file. In version 0.2.2 it only works in the "Track details" preview: in the session and in the recording, the track stays unchanged by it. The value is still saved per track (section 7). How to adjust the volume during a session is covered in section 5.
2 · Where to find the slider
- "Library" → hover over the track's row → a slider icon appears on the right of the row (tooltip "Edit loop markers") → click it. If the track already has markers, "∞" is shown there permanently. The "Track details" view opens.
- In "Track details", scroll to the "Level adjustment" section
- "Track volume" slider from -18 dB (very quiet) to +6 dB (louder)
- Default: 0 dB (original)
3 · Live preview
While moving the slider, you hear the change immediately — in version 0.2.2, though, only in the preview:
- In the "Track details" preview — if "Preview (from loop-in)" or "Preview (from start)" is running, level changes live (50 ms smooth ramp)
- In the session and in the recording — no change. If the track is currently playing in the cockpit, it sounds just as loud after you move the slider. The note above the slider ("applies instantly, even while the track is playing") only holds for the preview.
4 · Reset
Next to the slider: "0 dB" reset button. Click → level back to original.
5 · Range and recommendations
In version 0.2.2, these recommendations only apply to the "Track details" preview.
- −18 to −12 dB: track is too loud against the rest (e.g. AI-generated tracks with aggressive loudness)
- −9 to −3 dB: light correction
- 0 dB: original — default
- +3 to +6 dB: track is too quiet (e.g. uncompressed nature recordings). Watch for clipping on loud peaks.
During a session, adjust the volume with the "Music" slider at the top of the cockpit. It applies to all tracks in the phases together and affects both the speakers and the recording (the nature-sounds layer has its own "Nature" slider). If a single track is too loud or too quiet, adjust while it plays — the new value also stays for the following tracks. Details: Cockpit overview.
6 · When level adjustment isn't enough
For highly dynamic tracks (very quiet verses + very loud choruses), a pure gain adjustment doesn't help much. Real compression would be needed — we don't have that in the app right now. Workaround: compress the track in a DAW (Audacity, Reaper) and re-import it into Hypnotika.
7 · Persistence
The dB value is stored per track in localStorage. It survives app updates. On track re-import or after "Reset the app to factory defaults" (Settings → "Software & License"), it's reset to 0.
