An audio repair editor. Dialogue Isolate, spectral tools, and other modules vary by edition.
Dialogue in a noisy location
First identify the noise that makes the interview difficult to hear. Steady room noise and a sharp sound next to the microphone call for different approaches. In iZotope RX, you can inspect the recording on a spectrogram. In supported editions, Dialogue Isolate can reduce sounds around the voice. The developer's module list explains which tools are available separately and how they can be used in an editing project.
Compare a short excerpt
Take a learning snippet of the conversation where the buzz of the air conditioner overlaps the quiet end of the phrase. Save a copy of the source, mark the pause before the phrase and the area with the consonants. Only handle this segment. When comparing, set a close volume. If it is easier to understand the words, but exhaled and quiet consonants are gone, weaken the processing and listen to the end of the line.
When a single knock between words interferes, it makes sense to check the point edit in the spectral editor. It allows you to leave the rest of the site in its original state.
Preserve the ambience
Silence between phrases can sound unnatural next to an untreated shot. Listen to the result with the preceding and following takes. If the edit is still changing, keep both the original and a separate processed copy. Tools and processing modes differ across RX editions. For a project with many tracks, determine which modules run inside your editor and which need to run separately.

Terms
RX works as a separate audio editor and as a set of modules in supported programs. The availability of the desired operation depends on the version and format of the connection.From task to first result
Practical example
- Task
- Reduce background noise in an interview
- What to prepare
- An original speech recording with background noise; keep a separate, unchanged copy.
Task brief or prompt
Task brief: reduce noise in a speech recording while preserving natural word endings, breathing and vocal timbre. Compare the processed audio with the original at the same volume.
Expected result
A cleaned-up version of the recording; judge it by listening, not just by looking at the waveform.
How to check the result
- Listen to quiet word endings and pauses.
- Listen for metallic artifacts, cut-offs and changes in vocal timbre.
An editorial teaching example of a task brief, not the result of hands-on testing of the service. Check that the required mode is available, that you have rights to the source material and that the intended use of the result is permitted.
