The unsung hero of meeting room audio: digital signal processing (DSP)

Discover how DSP transforms meeting room audio – removing noise, echo & optimising sound so every voice is heard clearly.

In a meeting room, good audio should feel effortless. However, achieving that clarity takes more than just quality microphones and speakers. Behind the scenes, Digital Signal Processing (DSP) plays a vital role in ensuring that every voice is heard clearly, every word is intelligible, and distractions are kept to a minimum.

But what exactly is DSP, and why is it such a crucial part of effective AV system design?

What is DSP?

Digital Signal Processing uses software-based algorithms to clean and shape audio in real time. It can remove background noise, manage loudness levels, eliminate echo, and adapt sound to the room’s acoustics.

In a meeting room context, this means participants can focus on the conversation – not on struggling to hear or be heard.

Why DSP matters in meeting spaces

No two meeting room’s acoustics behave the same. Materials, ceiling height, room shape, glazing, furniture, and mic placement all affect intelligibility. DSP can help compensate for these variables using techniques such as:

Acoustic echo cancellation (AEC) – Stops remote participants from hearing their own voice fed back to them.

Noise reduction – Filters out unwanted sounds such as HVAC systems, keyboard typing, or distant conversations.

Automatic mixing – Balances the volume from multiple microphones, ensuring each voice is clear without manual adjustments.

Equalisation and tuning – Tailors the audio profile to suit the specific acoustics of the room, and to optimise microphone and loudspeaker performance

De-reverb – Reduction of the audible effects of reverberation to help eliminate hollow sound that degrades intelligibility.

Dynamics – Tools such as compressors and limiters can reduce levels to an acceptable dynamic range for comfortable listening.

Even premium hardware can underperform without this processing implemented correctly and appropriately to the room.

Different rooms need different DSP approaches

At MVS, we work closely with clients to ensure the right DSP solutions are in place based on the room type and use case. For example:

Huddle rooms & small meeting rooms

Often feature all-in-one solutions with built-in DSP that automatically manage echo and background noise.

Medium meeting rooms

Typically benefit from dedicated DSP processors, particularly when using multiple ceiling or table microphones.

Large boardrooms & multi-purpose spaces

Require more advanced DSP systems capable of handling complex audio routing, zoning, and bespoke tuning to guarantee consistent performance across the entire space.

Content creation & broadcast studios

While podcasts and studio recordings are often refined in post-production, many studios use DSP to clean audio in real time. This provides higher-quality sound from the start and reduces the time engineers spend editing later.

Integrating DSP with the wider AV ecosystem

DSP isn’t just a standalone solution. It’s integrated with microphones, loudspeakers, control systems, and video conferencing platforms to create a fully optimised AV experience. Brands like Q-SYS and Shure offer powerful DSP platforms that integrate seamlessly into larger ecosystems – something our technical team at MVS ensures is fully aligned with the client’s objectives and infrastructure.

How MVS approaches DSP

Choosing the right DSP requires technical insight and an understanding of how rooms are used day-to-day. Our team assesses layout, acoustics, and user behaviour before designing a system that delivers dependable clarity—not just on day one, but long-term.

If your meeting rooms suffer from weak audio, unstable performance, or complaints from remote participants, it’s worth reviewing your DSP setup.
