Hey everyone, I've been editing a short documentary for a local non-profit, and the dialogue audio from my interviews just sounds... off. It's not clipping or noisy, but it's muffled and has this weird 'boxy' resonance, like the person is speaking inside a cardboard box. I'm using a Rode Wireless GO II with the built-in lav mic, clipped to the talent's collar about 4-5 inches below their chin. I've tried messing with EQ in Premiere Pro (cutting around 300 Hz and boosting 3-5 kHz), but it still feels unnatural. Could this be a placement issue, or is it something else? I'm not using any room treatment, just filming in a small office with some furniture. Would a different lav mic or a boom setup help? Any advice on getting cleaner dialogue without a full studio setup would be awesome.
Dialogue audio sounds muffled and boxy – is my lav mic placement to blame?

Yeah, that 'boxy' sound is a classic sign of a lav mic being buried under clothing or too far from the mouth. The Rode Wireless GO II's built-in mic is omnidirectional, so it picks up a lot of room ambiance and chest resonance. At 4-5 inches below the chin, you're getting more chest boom and less direct voice. Try moving the mic higher, right at the sternum notch, and make sure it's not under a thick shirt – use a lav clip and run the cable so it doesn't rub. Also, check the internal recording level – if it's too low, you might be adding gain in post, which brings up the boxy room tone. I'd also suggest using the high-pass filter on the Rode (if you have the latest firmware) to cut the low-end rumble at the source.

Adding to that – the 'boxy' resonance is often from the mic capsule being partially covered by fabric or from reflections off the chest. I'd also recommend using a proper lav like the Sennheiser MKE 2 or a Countryman B3 if you can, as they have a more natural frequency response. But first, try the placement fix. Also, in post, instead of just EQ, try using a de-reverb or a dialogue denoiser like iZotope RX – the spectral de-noise and de-reverb modules can work wonders. But the real fix is to capture it clean. If you can, use a boom pole with a shotgun mic like the Rode NTG3 or Sennheiser MKH 416 – that will give you a much more direct, intimate sound. For interviews, a boom from above just out of frame is ideal.

One more thing – check your recording format. The Wireless GO II records a backup track internally at 24-bit/48kHz, but if you're using the 3.5mm output into your camera, make sure you're not clipping. Also, the internal recording can be used as a safety if the wireless signal drops. But for the boxy sound, I've had great results with a simple trick: in Premiere, use the 'Parametric EQ' and cut a narrow notch around 250-350 Hz (that's the 'boxy' zone), and then add a gentle presence boost at 5 kHz with a wide Q. But as mentioned, placement is key. Also, consider using a high-pass filter at 80-100 Hz to remove low-end rumble from HVAC or traffic – that can add to the muddiness.

I've also had good luck with using a 'lavalier in a bag' trick – if you're in a noisy or reverberant room, you can put the mic in a small windscreen or even a piece of foam to reduce some of the room tone. But the biggest improvement I've seen is using a dedicated lav with a proper clip that keeps the capsule exposed. And for editing, don't forget to use the 'Voice Over' effect in Premiere – it has a 'Presence' EQ that can help. Also, try matching the room tone in the edit – if you have gaps in dialogue, replace them with room tone to avoid sudden changes in background noise. That will make the dialogue feel more natural.

Thanks everyone, that was super helpful! I moved the lav higher up (right at the sternum) and made sure it wasn't under the shirt, and it made a huge difference – the boxy sound is gone. I also used the high-pass filter on the Rode and tweaked the EQ in Premiere with a notch at 300 Hz. The dialogue now sounds clear and natural. I'll definitely invest in a proper lav and maybe a boom for future shoots. Appreciate the quick responses – you guys saved my edit!
