Ambient Audio

Play scientifically-proven ambient sounds for focus, relaxation, meditation, and sleep. Perfect for programmers, office workers, students, and anyone needing...

Security Scan

The skill's purpose (play pre-generated ambient audio) mostly matches the code, but there are multiple implementation inconsistencies and omissions (missing samples, control/stop bugs) that make its behavior unpredictable — likely sloppy packaging rather than malicious, but you should inspect and test before use.

Purpose & Capability

The skill claims pre-generated 10s audio files in samples/ and instant playback; the repository contains only SKILL.md and scripts/play.sh (no samples directory or audio files). That omission means the skill as provided cannot perform its stated purpose without the missing sample files.

Instruction Scope

SKILL.md instructs the agent to run scripts/play.sh and to use ffmpeg/ffplay. The script itself only spawns ffplay locally (no network activity or secret access), which is within scope. However the control logic is buggy: it computes LOOP_COUNT but never uses it, starts ffplay with -loop 0 (infinite loop), and the background shutdown uses pkill -f 'ffplay.*focus-audio' even though the ffplay process command line does not include 'focus-audio' — so the script may not stop playback as advertised. These are functional/incoherence issues in scope rather than data-exfiltration concerns.

Install Mechanism

No install specification — instruction-only plus a local bash script. No downloads or external installers. This is the lowest-risk install mechanism.

Credentials

The skill requests no environment variables, credentials, or config paths. It requires ffplay (part of ffmpeg) and an audio output device, which are proportionate to the stated purpose.

Persistence & Privilege

The skill does not request always:true and does not modify agent/system configs. It writes a PID file to /tmp/focus-audio.pid and uses process management, which is reasonable for a local player. No elevated persistence or cross-skill configuration is requested.

What to consider before installing

This skill appears to be an instruction-only ambient audio player but is packaged incompletely and has bugs. The samples/ audio files referenced in SKILL.md are not included, so it won't play until you add or generate the MP3s. The player starts ffplay with an infinite loop (-loop 0) and attempts to stop it using a pkill pattern that won't match the ffplay command line; as a result playback may not stop when the script reports it did. Before installing or running it: (1) inspect or add the samples/ files yourself (or generate them with the provided ffmpeg example), (2) review and fix the stop logic (use the saved PID to kill the ffplay process and/or include a unique marker in the ffplay invocation so pkill matches), and (3) test in an isolated environment (not a shared production server) so stray audio processes or aggressive kill -9 calls don't affect other services. There are no signs of network exfiltration or credential requests, but because the package is incomplete and buggy, treat it as untrusted code until you verify/fix it.

Ambient Audio - Ambient Sound Player

Play white noise, pink noise, brown noise, brain wave tones, and more for deep focus, relaxation, or sleep. Runs on Linux servers with audio output.

All audio files are pre-generated (10-second loops) for instant playback. No copyright concerns - sounds are algorithmically generated.

Quick Start

# Play white noise (default, 10 seconds)
bash scripts/play.sh white

# Play specific type
bash scripts/play.sh pink
bash scripts/play.sh brown
bash scripts/play.sh theta

# With duration
bash scripts/play.sh white -d 30     # 30 seconds
bash scripts/play.sh pink -d 60       # 1 minute

# With volume control (0.1 - 2.0)
bash scripts/play.sh white -v 0.5     # 50% volume

# Stop playing
bash scripts/play.sh stop

# List all available modes
bash scripts/play.sh --list

Available Audio Types

🎯 Focus (Concentration)

Mode	Best For	Description
white	Deep work, coding	Classic white noise - eliminates ambient distractions
alpha	Light focus	Alpha waves (8-14Hz) - relaxed alertness
beta	Active thinking	Beta waves (14-30Hz) - mental clarity
gamma	Peak focus	Gamma waves (30Hz+) - cognitive enhancement

😌 Relax (Stress Relief)

Mode	Best For	Description
pink	Gentle background	Softer than white, easier on ears
rain	Reading, working	Simulated rain ambience
nature	Breaks	Filtered natural-style ambience

😴 Sleep (Rest)

Mode	Best For	Description
brown	Deep sleep	Deep, rumbling noise - best for sleeping
delta	Sleep onset	Delta waves (0.5-4Hz) - helps fall asleep

🧘 Meditation

Mode	Best For	Description
theta	Meditation	Theta waves (4-8Hz) - deep relaxation
binaural	Focus/relax	10Hz binaural beats - brain wave entrainment
bowl	Calming	Singing bowl - instant calm

Usage Examples

Voice Commands (via AI Assistant)

• "Play white noise" → Starts white noise
• "I need to focus for coding" → Plays white/alpha
• "Can't sleep, play something" → Plays brown noise
• "Let me meditate" → Plays theta waves
• "Stop" → Stops playback

Custom Duration

# 5 minutes (300 seconds)
bash scripts/play.sh white -d 300

# 1 hour
bash scripts/play.sh brown -d 3600

Volume Control

# Half volume
bash scripts/play.sh white -v 0.5

# Quiet (25%)
bash scripts/play.sh pink -v 0.25

# Louder
bash scripts/play.sh brown -v 1.5

How It Works

1. Pre-generated Audio: All sounds are 10-second loops stored in samples/ directory
2. Instant Playback: ffplay loops the file seamlessly
3. Duration Control: Calculates loop count: duration / 10
4. Volume Control: Uses ffplay's -af volume= filter

Requirements

• ffmpeg: For audio playback

  sudo apt-get install ffmpeg
  

• Audio output: Speakers or headphones connected to the server

Troubleshooting

No sound plays

• Check if audio device is connected: aplay -l
• Check if ffplay is installed: which ffplay
• Verify audio file exists: ls samples/

Audio too loud/quiet

• Adjust volume: bash scripts/play.sh white -v 0.3

Want to add more sounds

• Generate new 10-second loop:

  ffmpeg -y -f lavfi -i "anoisesrc=d=10:c=pink:a=0.35" -c:a libmp3lame -b:a 64k -t 10 newname_10s.mp3
  

• Place in samples/ directory

Technical Notes

• Audio Format: MP3, 48kHz, mono, 64kbps
• Loop Duration: 10 seconds (seamless loop)
• Volume Range: 0.1 - 2.0 (default 1.0)
• Max Duration: No hard limit (limited by system resources)

Security

• Input validation on volume and duration parameters
• File paths are hardcoded (no user input for paths)
• No external network calls
• No sensitive data access
