Description
Ultra Scary Horror Sounds is a powerful iOS utility app designed to deliver an immersive horror soundboard experience with 22 distinct synthesized effects organized into three chilling categories: Ghosts & Voices, Creatures & Stings, and Ambience. Perfect for atmosphere, pranks, or creative projects, this app offers extensive customization and utility features to control playback and create layered horror soundscapes.
Key Features:
- Extensive Sound Library: 22 unique horror-style sounds synthesized on-device, including ghostly moans, whisper bursts, creepy cackles, jump stings, glass scrapes, deep drones, wind howls, door creaks, and more.
- Categorized Soundboard: Easily browse sounds by category with a segmented control and adaptive grid layout optimized for both iPhone and iPad.
- Recent Plays Strip: Access your last 14 played sounds quickly with a horizontal chip strip; clear recents anytime.
- Search & Favorites: Filter sounds by title or subtitle with case-insensitive search. Mark favorites with a star icon and toggle to view favorites only; favorites persist across sessions.
- Random Sound Playback: Use the toolbar dice button to play a random one-shot sound respecting mix layer settings; shake your device optionally to trigger a random sound with haptic feedback.
- Playback Controls: Adjust playback speed from 0.5× to 1.75× with live rate readout, altering pitch and duration.
- Mix Layers: Enable mixing to play two one-shots simultaneously or overlay one loop with a one-shot, or disable for single-stream playback.
- Reverb Space Effect: Apply a wetness slider (0–100%) to add algorithmic cathedral-style reverb (multi-tap delay) enhancing the spooky atmosphere.
- Burst Playback: Play 1 to 5 sequential hits for non-looping sounds, perfect for knock patterns or repeated stings.
- Sleep Stop Timer: Schedule automatic audio stop after 5 to 180 minutes to avoid prolonged playback; timer shows remaining minutes.
- Keep Screen Awake: Option to prevent the device from sleeping while audio plays, ensuring uninterrupted ambiance.
- Master Volume Control: Adjust overall app volume with persistence across sessions.
- Lock Screen & Control Center Integration: Now Playing info updates with sound title, artist, duration, and playback rate; remote commands support stop and pause.
- Prank Timer: Arm a delayed playback timer from 5 to 120 seconds with selectable sound or random sound each time, ideal for prank setups with on-screen responsible use reminders.
- Haptics Feedback: Optional impact feedback on sound play, random triggers, and heavy impact on shake events when enabled.
- Safety & Info Tab: Detailed guidance on responsible use, health and hearing safety, layered audio loudness warnings, and explanation of the new synthesized sound engine.
Technical Highlights:
- All sounds are synthesized on-device using deterministic noise, FM synthesis, envelopes, and DSP algorithms without third-party audio files.
- Audio pipeline includes PCM generation, algorithmic reverb processing, WAV packaging, and playback via AVAudioPlayer instances supporting multi-track layering and burst sequencing.
- Uses AVAudioSession with playback category allowing mixing with other audio and Bluetooth A2DP support.
- Background audio mode enabled for looping ambience to continue briefly when app is backgrounded.
- Shake detection uses CoreMotion accelerometer with debounce to prevent spam triggers.
- No network connections, no analytics, no ads, no in-app purchases, and no permissions beyond standard app requirements.
Usage Tips:
- Use the timer feature to prank friends safely and consensually.
- Combine looping ambience with one-shot stings using mix layers for layered horror effects.
- Adjust playback speed and reverb wetness to customize mood and intensity.
- Use favorites and search to quickly access preferred sounds during live use.
- Enable shake trigger with caution and only in appropriate contexts to avoid unintended scares.
