README (SKILL.md)
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
- Pre-generated Audio: All sounds are 10-second loops stored in
samples/directory - Instant Playback: ffplay loops the file seamlessly
- Duration Control: Calculates loop count:
duration / 10 - 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
Focus Audio - Improve concentration, reduce stress, sleep better.
Usage Guidance
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.
Capability Analysis
Type: OpenClaw Skill
Name: ambient-audio
Version: 1.0.0
The skill contains a shell injection vulnerability in `scripts/play.sh` because the `VOLUME` and `DURATION` arguments are used in command strings without sanitization, allowing for arbitrary command execution. Although `SKILL.md` explicitly claims that 'Input validation on volume and duration parameters' is performed, the actual script lacks any such logic. Additionally, the script uses a predictable PID file at `/tmp/focus-audio.pid`, which is an insecure practice that could be exploited for local denial-of-service or process signaling attacks.
Capability Assessment
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.
How to Use
