Sound Designer Composer for Premium Mobile Breathapp: Ambient Minimalism Contemplative Soundscapes

Sound design brief — mobile audio experience

we are looking for a sound designer/composer specialized in:

* ambient minimalism
* cinematic textures
* contemplative soundscapes
* nervous system regulation audio
* guided breathing pacing
* seamless looping
* premium sensory audio experiences

the project involves creating layered audio assets for a mobile state-regulation and guided breathing experience.

---

## core objective

the audio should feel:

* calm
* grounded
* elegant
* organic
* immersive
* emotionally safe
* deeply minimal

the goal is not stimulation.
The goal is regulation.

The experience should transmit:

* safety
* deceleration
* presence
* spaciousness
* subtle emotional reorganization

Silence and negative space are considered part of the composition.

---

## general creative direction

references:

* premium minimalism (apple-level restraint)
* cinematic ambient
* contemplative sound design
* nervous system calming
* subtle sensory immersion

avoid:

* strong melodies
* “new age” clichés
* dramatic emotional builds
* aggressive frequencies
* recognizable instruments
* traditional musical structure
* anything that feels overstimulating

this should not feel like “music”.
It should feel like an evolving sensory atmosphere.

---

## session structure

audio will be created for two session lengths:

short session

* total duration: 63 seconds

long session

* total duration: 181 seconds

both sessions include:

* intro
* breathing cycles
* evolution
* landing/fade-out

all elements must fit inside the total duration.

---

## breathing / pacing

official breathing pacing:

* inhale: 5.5 seconds
* Exhale: 5.5 seconds
* Full cycle: 11 seconds

All breathing-related sonic movement must respect this pacing structure.

The audio should guide breathing subtly — never mechanically.

---

## sonic states (4 states)

we need 4 distinct sonic signatures, all emotionally coherent with each other.

1. HEAVY
  Dense, grounded, warm-low, compact, safe.

2. DRIFTING
  Airy, diffuse, floating, unfocused, spatial.

3. RETURNING
  Balanced, stabilizing, gradually reorganizing.

4. CENTERED
  Open, harmonic, expansive, coherent, calm.

All states should share the same tonal universe to preserve continuity between transitions.

Suggested tonal foundation:

* D Dorian
  or
* D minor pentatonic

---

## asset architecture

for each state, create:

* 3 drone base variations
* 1 breath pulse layer
* 1 harmonic evolve layer

suggested structure:

audio/
├── heavy/
├── drifting/
├── returning/
└── centered/

---

## asset details

drone base

* seamless loop mandatory
* approximately 60 seconds
* slow-moving
* textural
* emotionally stable
* no obvious harmonic resolution

breath pulse

* softly synchronized to the 11-second breathing cycle
* extremely subtle
* should never feel like a metronome
* should gently induce pacing and presence

harmonic evolve

* long evolving layer
* extremely gradual progression
* subtle harmonic opening over time
* no dramatic climax

---

## universal files

session_intro

* soft atmospheric swell
* approximately 5 seconds
* no defined tonal center
* transitional only

session_outro

* soft resolution into silence
* integrated within total session duration
* smooth perceptual landing

---

## technical format

master files (validation stage)

* wav
* 48khz
* 24-bit
* stereo

final delivery for app

* codec: opus
* extension: .opus
* 48kHz
* Stereo

Important:
Please avoid OGG Vorbis.

---

## loudness / leveling

per individual stem:

* approximately -28 lufs integrated
* max true peak: -6 dbtp

combined layered mix target:

* approximately -23 lufs

---

## important notes

* all loops must be perfectly seamless.
* Audio will be used with headphones and mobile speakers.
* The app itself will control:

  * crossfades
  * layer blending
  * breathing synchronization
  * fade-in / fade-out
* Audio must leave room for visual and perceptual focus.
* Subtlety is extremely important.

---

## workflow (preferred)

1. Create draft for ONE state first
2. Technical + aesthetic validation
3. Produce remaining states
4. Final masters delivery

---

## PLUS / NICE TO HAVE

Experience with:

* spatial audio
* binaural concepts
* contemplative UX audio
* wellness apps
* cinematic ambient production
* procedural audio thinking

When applying, please send:

* portfolio
* relevant examples
* DAW used
* previous experience
* availability
