Key Facts:
- Sound cleanup involves addressing noise, reverb, and inconsistent volume using techniques like noise reduction and EQ.
- Equalization (EQ) helps reduce boominess (100-250 Hz) or harshness (15 kHz+) and manage reverb (300 Hz to 1 kHz).
- Compression balances dynamic range, making quieter parts louder and louder parts softer for consistent volume.
- De-essers target sibilance, typically in the 5-15 kHz range, for clearer vocal delivery.
- Adherence to loudness standards, like -21 to -23 LUFS, is crucial for a professional and consistent listening experience across platforms.
Audio Mixing Principles
Audio mixing is the process of combining individual audio tracks into a cohesive and balanced stereo mix, ensuring each element is clear and contributes to the overall narrative without overpowering the primary content. This involves setting proper audio levels, applying equalization, and using compression.
Key Facts:
- Proper Audio Levels ensure each track's volume is balanced, especially crucial for podcasts with multiple speakers where independent adjustment is key.
- Equalization (EQ) shapes the tonal balance of audio, using high-pass filters to remove low-frequency rumble and targeting specific frequency ranges to address boominess (200-250 Hz) or enhance clarity (1-4 kHz).
- Compression controls the dynamic range of audio, making quieter parts louder and louder parts softer for a more consistent sound.
- Compressor parameters include Threshold (level at which compression begins), Ratio (amount of volume reduction), and Attack/Release (speed of compression application and cessation).
- General EQ best practices suggest cutting frequencies before boosting them and limiting adjustments to +/- 3 dB to avoid a cluttered mix.
Loudness Standards and Mastering
Mastering is the final stage of audio post-production, ensuring the podcast has a polished, professional sound with consistent loudness across different platforms and devices. This includes adherence to loudness normalization standards like LUFS and managing true peak levels.
Key Facts:
- Loudness Normalization, measured in LUFS (Loudness Units Relative to Full Scale), ensures consistent perceived loudness across platforms, preventing listeners from constantly adjusting volume.
- Common LUFS targets for podcasts range from -16 LUFS for stereo files to -19 LUFS for mono files, with Apple Podcasts recommending -16 LUFS.
- True Peak (TP) levels should be kept around -1.0 dB to prevent clipping and distortion, especially when using lossy encoders for distribution.
- Mastering involves final, subtle adjustments to compression and EQ to optimize overall tonal balance and dynamics.
- Quality source audio is paramount, as mastering enhances but cannot fundamentally fix poor recordings, emphasizing the importance of good recording practices.
