Case Study: Fixing Podcast Sound with a RØDECaster Pro II

By Paul Andrews, Founder

The Challenge

A new venture in West London had invested thousands into creating a visually stunning podcast studio, complete with comfortable sofas, professional lighting, a RØDECaster Pro II, and industry-standard Shure SM7B microphones. However, despite the premium gear, the recorded sound was described as “sub-par,” leaving guests unhappy and the owners bewildered. Fearing they might need to purchase even more expensive equipment to fix the problem, they brought me in to diagnose why their professional setup was yielding amateur results.

The Amazing Audio Solution

My forensic investigation began with the basics: tracing the physical signal path, checking cables, and verifying the input gain staging. The signals were clean, strong, and not clipping, and the multi-track recording into Adobe Audition was configured correctly. The root cause was hidden in the RØDECaster’s internal processing: the onboard effects were aggressively over-processed and inconsistently applied across different channels, creating a jarring, unnatural sonic caricature of the human voice.

The solution was to strip the technology away, establish a clean foundation, and apply processing with surgical precision. Here is how we achieved that:

• Neutralising the Main Processors: The studio’s initial settings had ‘Depth’ (a low-frequency harmonic exciter) and ‘Sparkle’ (a high-frequency exciter) pushed to near-maximum on some channels. I disabled these entirely across all channels, allowing the Shure SM7B to capture a natural, pure vocal signal.
• Applying Subtle Compression: I dialed in a small amount of ‘Punch’—around 15%—uniformly across all channels. This acted as a gentle leveller, ensuring broadcast-ready consistency so no guest was dramatically louder or quieter than another, without crushing the dynamics.
• Refining Advanced Settings: I bypassed heavy post-production tools like the De-Esser, Exciter, and Big Bottom, and left the EQ completely flat. I then engaged a steep High-Pass Filter (30-40Hz) to remove room rumble from air conditioning, set the compressor for gentle peak taming only, and added a conservative, fast-acting noise gate to reduce room noise without cutting off softly spoken words.
• Creating Reusable Templates: To ensure the settings wouldn’t be lost, I saved this clean configuration as a new ‘Show’ on the RØDECaster and created a corresponding multi-track template in Adobe Audition, allowing the clients to launch future sessions with a single click.

The Result

Before leaving, I recorded a sample with one of the hosts and taught them how to apply a custom EQ preset in Adobe Audition tailored specifically to add mid-range presence to their voice. This empowered them to apply the same logic to their regular guests. A week later, the owners messaged me to say their first session was a resounding success. Everyone commented on the dramatically improved audio quality, and their studio finally sounded as professional as it looked.
