Ambient Audio

Play scientifically-proven ambient sounds for focus, relaxation, meditation, and sleep. Perfect for programmers, office workers, students, and anyone needing concentration or rest. Use when user wants: white noise, pink noise, brown noise, rain sounds, singing bowl, binaural beats, brain wave tones (alpha/beta/gamma/theta). No copyright issues - all audio is algorithmically generated using ffmpeg.

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
