prostir zvuku

Product Introduction

1. Definition: prostir zvuku is a spatial nature sound mixer application designed exclusively for macOS (14 and later). It functions as a personalized ambient sound studio, allowing users to construct immersive, three-dimensional soundscape environments using a library of high-fidelity nature recordings.
2. Core Value Proposition: The application exists to solve the modern problem of auditory distraction and digital overwhelm by enabling users to build a focused, restful, or sleep-inducing acoustic space. Its primary function is to place and manipulate sounds not just in a stereo field, but on a spatial canvas, allowing for precise environmental sound design to enhance concentration, relaxation, and sleep quality.

Main Features

1. Spatial Audio Canvas: The core interface allows users to drag and position individual sound layers onto a 2D canvas that represents a 3D space. Sounds like rain, fire, ocean waves, wind, birdsong, forest ambience, thunder, crickets, and streams can be placed at varying perceived distances and directions. This spatial mixing capability lets users create dense or open, close or distant, calm or active environments, providing granular control over their auditory surroundings.
2. Notch Bar Integration: For seamless control, the app integrates a persistent control panel in the macOS menu bar and a dedicated Notch Bar. Users can save their custom soundscapes (presets) and instantly pause, switch between scenes, or adjust layers without needing to open the main editor window. This feature ensures unobtrusive, always-accessible session management.
3. Gentle Endings & Custom Timers: To support work sessions, meditation, or sleep routines, the app includes a configurable sleep timer. Unlike abrupt stops, the scene fades out gradually when the timer completes. Presets include 5, 15, and 30-minute options, plus a 1-hour setting and a custom duration, making it ideal for timed focus blocks or falling asleep.
4. Optional Head Tracking with AirPods: Utilizing Apple's native HRTFHQ (Head-Related Transfer Function High Quality) binaural engine, the app can anchor the entire sound field to the user's head position when using supported AirPods (Pro or Max). As the user turns their head, the auditory scene remains stationary in the virtual room, creating a truly immersive spatial audio experience. All processing is handled natively via the AVAudioEngine framework on the Mac, ensuring privacy and performance.
5. Full Offline Operation & Freeware Model: The entire sound library is bundled within the app, requiring no streaming or account login after download. The core product is permanently free, offering the full sound library, spatial canvas, head tracking, and menu bar controls. Free tier limitations include a maximum of 3 simultaneous sound layers and a 5-minute timer. A one-time Lifetime Pro purchase (no subscription) unlocks unlimited layers, timers, and saved rooms.

Problems Solved

1. Pain Point: Auditory distraction and lack of a controllable acoustic environment in open-plan offices, noisy homes, or during travel, which disrupts concentration, relaxation, and sleep quality. Generic white noise or simple looping sounds fail to provide a personalized, engaging, or spatially realistic environment.
2. Target Audience: The primary users include remote workers and programmers needing to block out distractions for deep work, individuals with insomnia or sleep difficulties seeking effective auditory sleep aids, students studying in noisy environments, creative professionals looking for a customized background ambiance, and mindfulness practitioners using sound for meditation.
3. Use Cases: Essential for creating a focused work zone in a shared office, establishing a pre-sleep wind-down routine, masking disruptive urban noise, enhancing relaxation during a massage or yoga session, or building a personalized auditory backdrop for creative writing or coding.

Unique Advantages

1. Differentiation: Unlike standard white noise or static ambient sound applications, prostir zvuku differentiates itself with its interactive spatial canvas. While other apps offer preset mixes or simple volume controls, this product provides a direct manipulation interface for positioning sounds in a virtual 3D space. Furthermore, its deep OS-level integration via the Notch Bar and its use of Apple's native spatial audio and head-tracking technology set it apart from web-based or cross-platform alternatives.
2. Key Innovation: The key innovation is the fusion of a user-friendly spatial mixing interface with professional-grade, native Apple binaural audio processing. By leveraging the HRTFHQ engine and AVAudioEngine directly on macOS, it delivers a low-latency, high-fidelity spatial sound experience that feels anchored to the physical environment when used with compatible AirPods, moving beyond simple stereo panning to true environmental acoustics simulation.
