Tackling Outdoor Recording Challenges in Audio Editing

Recording audio outdoors brings a certain rawness and energy that no studio can replicate. The ambient hum of a marketplace, the natural reverb of an open courtyard, the texture of a real-world environment – these are the qualities that make field recordings compelling. But that same authenticity comes with a price: unwanted noise, uneven levels, sudden sonic intrusions, and a host of technical problems that can undermine even the most riveting content. Editing outdoor recordings is a discipline of its own, demanding a more careful, nuanced approach than editing a clean studio session. Here is how to handle the six core challenges that every outdoor audio editor faces.

Managing ambient noise without losing the location’s feel

Outdoor environments are never truly silent. A busy street interview will have traffic underneath it. A park recording will have children, wind, and birdsong. This constant background texture is called ambient noise, and the biggest mistake an editor can make is trying to eliminate it entirely.

Noise in recordings comes in many forms – from the constant hum of traffic to sudden bursts of transient sound – and understanding the difference between the two is the first step to treating them correctly. For steady, constant ambient noise (traffic hum, wind rumble, crowd murmur), the right tool is a noise reduction effect. Tools like Adobe Audition’s Noise Reduction feature work by first sampling a portion of audio that contains only the background noise, then using that “noise profile” to subtract those frequencies from the rest of the recording.

The critical rule here is restraint. Pushing noise reduction too hard creates a hollow, artificial “underwater” effect that sounds far worse than the original ambient noise. Apply it at a conservative level – enough to reduce the distraction, not enough to sterilize the soundscape. The goal is clarity, not silence. The location’s acoustic fingerprint is part of the story.

Handling occasional, intermittent sounds

Intermittent noises – a dog barking in the distance, a car horn, someone laughing off-camera – are a completely different problem from constant ambient noise, and they demand a completely different solution. Applying noise reduction across the entire track to address a single dog bark is both ineffective and destructive to the rest of the audio.

The correct approach is surgical, localized editing. Manually editing out unwanted sounds from specific segments of your recording – rather than treating the whole track – gives you precise control that automated tools simply cannot match. Zoom into the waveform, isolate the exact section containing the intrusive sound, and apply noise reduction, volume automation, or a fade only to that specific clip. This way, the rest of the recording remains completely untouched and natural.

Spectral editing, available in tools like iZotope RX and Adobe Audition, takes this even further by allowing you to visualize your audio as a spectrogram and literally “paint out” the unwanted frequency at the exact moment it occurs. This is particularly effective for isolated, sharp sounds that sit in a different frequency range from the speaker’s voice.

Eliminating unnecessary repetitions

In a natural conversation – especially one recorded outdoors where interviewees may feel less “on mic” – people repeat themselves constantly. They restart sentences, circle back to a point already made, or rephrase the same idea three times before landing on the version they actually wanted. Left in the edit, these repetitions slow the pace, frustrate the listener, and make the programme feel longer than it needs to be.

Removing superfluous content – repeated sections, lengthy tangents, and restarts – is a foundational editing task. Listen through the full recording first to understand the arc of the conversation, then go back and cut the repetitions that add no new value. When combining content from the same speaker across a cut, always use a brief crossfade to prevent a jarring, abrupt jump in the audio.

However, not every repetition should be cut. Removing every filler and repetition can make speech sound robotic and unnatural. Sometimes a speaker repeats a key phrase for deliberate emphasis – “this was not just a mistake, it was a fundamental mistake” – and removing that second instance would strip out the rhetorical force the speaker intended. The editor’s job is to distinguish between a repetition that is noise and a repetition that is meaning. This judgment should always be guided by the purpose of the programme and who its audience is.

Balancing audio levels from a single recorder

In an ideal world, an outdoor interview would use two microphones on two separate tracks – one for the interviewer, one for the interviewee. In practice, particularly in field journalism and documentary podcast work, a single portable recorder is often the only option. The result is a single track where the interviewer’s voice (closer to the mic) sounds significantly louder than the interviewee’s, or where one speaker’s volume shifts dramatically as they turn their head or move.

Inconsistent volume is one of the clearest signs of low-quality audio, and it forces listeners to constantly adjust their device volume – an experience that drives them away. The solution is to address levels in post-production using a combination of techniques. Clip gain adjustments let you raise or lower the overall level of individual sections. Compression works dynamically within a clip, reducing the peaks of loud passages and bringing up the quieter parts to produce a consistently even sound.

Tools like Auphonic are specifically designed to automate this process, balancing levels between speakers and normalizing loudness across the entire programme with minimal manual intervention. For manual work in Adobe Audition, the Speech Volume Leveler tool, set to its “Careful” preset, can also help even out speaker levels without making the changes sound heavy-handed. The industry standard target for spoken content is around −16 LUFS for stereo output, ensuring your programme sounds consistent on all platforms and playback devices.

Removing plosive “blow” sounds

When a speaker’s mouth is positioned too close to a recorder – common in handheld field recordings – certain consonants cause a sudden, forceful burst of air to hit the microphone’s diaphragm. The result is a low-frequency thump or “pop” sound on the recording. Plosives are caused by consonant sounds – particularly P, B, D, T, and K – where airflow is completely blocked in the vocal tract before being suddenly released. This burst of pressure overloads the microphone and produces an audible distortion that is distracting and unprofessional.

Unlike ambient noise, plosives cannot be addressed with a blanket noise reduction pass. They require targeted, individual treatment. Here are the most effective approaches:

De-amplify/volume reduction: Zoom into the waveform and isolate only the plosive transient. Highlight the plosive section and use your DAW’s gain or volume tool to reduce the volume of that specific moment, leaving the surrounding audio untouched. Reduce enough to make the pop inaudible, but not so much that a noticeable dip in volume is introduced.
Fade-in tool: Split the clip at the height of the plosive and apply a very short fade-out and fade-in. If the fade is brief enough, it becomes effectively invisible to the listener while eliminating the pop.
Draw tool / automation: In DAWs that support volume automation, you can manually draw a volume dip precisely over the plosive’s waveform peak, then bring the volume back up – a highly precise method that avoids destructive editing.
High-pass filter: Low-cut and high-pass filters can attenuate the bass frequencies that plosives occupy, typically below 120Hz, reducing the energy of the pop. Apply this filter selectively to the plosive section only, not the entire track.
Dedicated plug-ins: Tools like iZotope RX De-Plosive automate plosive detection and removal with minimal artifacts, making them invaluable for recordings with frequent occurrences.

It is worth noting that plosives primarily affect the low end of the frequency spectrum. When using any of these tools, be careful not to cut so aggressively that you strip warmth and presence from the speaker’s voice in the surrounding audio.

Avoiding complete silence in gaps

Once noise reduction has been applied to an outdoor recording, there is a strong temptation to also silence the gaps between sentences and words – those brief pauses where the background noise is most noticeable. This is one of the most common and damaging mistakes in outdoor audio editing.

When a listener hears audio – even imperfect outdoor audio – they unconsciously calibrate to the sonic environment. Their brain accepts the ambient noise as the baseline of “normal.” If you then hard-cut to complete digital silence during a pause, that absence of sound is instantly jarring. A natural change in ambient levels is acceptable to listeners, but a sudden cut to complete silence signals that something is wrong with the recording and breaks immersion entirely.

The professional solution is to retain a low level of room tone or ambient fill in every gap. If your noise reduction has left the pauses too clean, record a few seconds of the location’s ambient sound at the same recording session and use it to fill the gaps – a technique called room tone replacement. A touch of background ambience adds a sense of realism, and its absence is what makes over-processed audio sound artificial. The ear expects the world to have texture. Give it that texture, even in the silences.

The editor’s mindset for outdoor audio

Editing outdoor recordings is fundamentally about serving two competing priorities at once: clarity and authenticity. Every decision – how much noise to reduce, which repetitions to cut, how to treat a plosive – has to be weighed against the question of whether it makes the programme easier to listen to without making it feel like it was recorded in a studio. The location is part of the journalism. Preserve it.

The best outdoor edits are the ones nobody notices. The voices are clear, the levels are consistent, the distractions are gone – and yet the listener still feels like they were there.

What do you think? When you listen to a podcast or radio documentary recorded outdoors, do you notice the ambient sound as a distraction – or does it actually make the content feel more real and credible? And where do you think the line is between cleaning up audio and scrubbing away its authenticity?
