Sound Recording Techniques
Recording is the foundation of many audio projects, requiring precision and technical skill.
Microphone Placement
- Close Miking
- Overhead Miking
- Room Miking
- Stereo Techniques (XY, ORTF, Blumlein, MS)
Signal Flow in Recording
1. Microphone captures sound
2. Signal passes through preamp
3. Signal is processed via EQ and dynamics
4. Recorded onto DAW or tape
Best Practices for Recording
- Use quality cables and connectors
- Maintain proper gain staging
- Minimize ambient noise
- Monitor levels to avoid clipping

Mixing and Mastering
Mixing involves balancing multiple audio tracks, while mastering prepares the final product for distribution.
Mixing Fundamentals
- Volume Balancing
- Panning
- Equalization (EQ)
- Dynamics Processing (Compressors, Limiters)
- Effects (Reverb, Delay)
Mastering Essentials
- Final EQ Adjustments
- Compression and Limiting
- Stereo Width Enhancement
- Sequencing and Spacing
- Format Conversion and Dithering
Tips for Effective Mixing
- Listen on multiple systems
- Take breaks to prevent ear fatigue
- Use reference tracks
- Trust your ears, not just meters
