Ep26 Loudness and Impact

Key takeaways

Loudness and impact, while related, are distinct concepts that can be managed using various audio techniques.
Effective mixing requires a balance of SPL management, especially under environmental constraints like live performances.
Utilizing tools like EQ and compression thoughtfully enhances the perception of loudness and impact in a mix.
Dynamic EQs and multi-band compressors serve specific purposes in mixing, allowing for targeted control over frequency ranges.
Engagement with the audience is vital for sharing knowledge and improvement in audio engineering topics.

Summary

Understanding Loudness and Impact

The podcast hosts explore the definitions of loudness, impact, and sound pressure level (SPL). Loudness is discussed as a perceptual attribute that affects how sound is experienced, while impact refers to the physical sensation of sound. The discussion delves into how these two concepts, while related, are not synonymous. They emphasize the importance of controlling SPL in live settings to avoid hearing damage and maintain a high-quality audio experience.

Challenges of Achieving Impact in Different Environments

The hosts discuss various limitations faced in live sound situations, including SPL restrictions imposed by regulations and the constraints of live streaming. They highlight the challenges posed by acoustically unfavorable environments, such as reverberant rooms, where simply increasing volume isn’t effective. The discussion encourages sound engineers to be innovative in their approach to achieve loudness and impact without exceeding SPL limits.

Using Tools for Loudness and Impact

Key mixing techniques and tools are presented to enhance impact and loudness, including EQ, compression, saturation, and dynamic management strategies. They discuss the role of EQ in achieving perceived loudness by adjusting frequency content, along with how compression can shape dynamics to make sounds feel more impactful. The conversation also covers the use of saturation to add harmonic content that contributes to a fuller sound.

Dynamic EQ and Multi-Band Compression

This section explains the distinct roles of dynamic EQ and multi-band compression in live sound. Dynamic EQ is highlighted for its precision in targeting specific frequencies and its ability to respond to varying signal levels, making it useful for managing vocals and instruments dynamically. Multi-band compression is discussed as a more general tool for managing frequency bands, particularly useful during mix output.

Conclusion and Audience Engagement

The hosts wrap up the discussion by inviting listeners to engage with the show through feedback, questions, and topic suggestions. They encourage their audience to follow them on various platforms and to continue learning about audio engineering through their content.

Show notes

We ask the age-old question, What can I do to make my mix feel loud without actually just turning it up? And what about streaming, how do I make a livestream seem loud? What defines impact, and what are some tools we can use to maximize the feeling of impact without having to simply make the show push more SPL?
