Cleaning up interview audio with RƎLAY waveform editing
Talkback radio still rules Australian drive-time, and community stations fill the FM dial from Broome to Burnie. Producers at the ABC's Ultimo studios and podcast crews working out of Melbourne share the same headache: cleaning up phone-ins and field recordings without flattening the cadence of an Australian conversation.
RƎLAY has become a practical software tool for radio producers needing pro-grade cleanup without a full DAW's footprint. Built around Lawo's Broadcast 3.0 thinking, it runs on a standard workstation and sits comfortably beside Power Core or Ruby. For studios juggling regional staff, remote guests, and tight turnarounds, that flexibility matters.
Waveform editing inside RƎLAY turns an interview file into a visual map of every breath, pause, and phone artefact. Cuts land on zero-crossings, breaths get flagged, and lengthy silences trim away without leaving the application. The work happens close to on-air speed, which is exactly what newsrooms in Sydney and Perth demand when a press conference lands at 5pm ahead of the 6pm bulletin.
Below: what the editing surface offers, how the repair tools handle messy real-world audio, and why studios in Adelaide and Brisbane have folded RƎLAY into their daily routine.
What RƎLAY brings to the editing room
RƎLAY is a virtual radio platform, but its waveform editor behaves like a focused workbench. Clips load quickly from a network share or local drive, and the display zooms down to individual samples. For a producer chasing a usable soundbite from a forty-minute council recording, that responsiveness saves minutes.
The interface feels familiar to anyone who cut tape in a station trained by engineers from Adelaide. Selections snap to markers, edits stay non-destructive, and a history panel lets the user step back when a trim removes half a sentence. Layered tracks handle cleanly, making interview-with-host workflows straightforward.
| Editing Function | RƎLAY Waveform Editor | Full DAW | Browser Editor |
|---|---|---|---|
| Non-destructive cuts | Yes | Yes | Limited |
| Breath detection markers | Built-in | Plug-in only | No |
| Networked session loading | Native | File-based | Variable |
| Console recall | Power Core / Ruby | External | No |
Repair tools for real-world recordings
Phone audio dominates Australian talkback, and RƎLAY exposes a tight repair set tuned for that job. The de-noise module keeps the warmth of a broadcaster's voice while lifting hiss from a mobile uplink patched through a Comrex box at a regional footy match. Click removal handles dropouts from VoIP contributors phoning in over patchy NBN.
Interviews recorded across multiple sessions tend to drift in level. The editor's gain-ramping tool handles this inside the clip, removing a separate normalisation pass. Producing a current-affairs segment for ABC RN or a community outlet along the Murray becomes a matter of selecting the right region and dragging the gain handle.
Stereo field recordings captured at a Fremantle market or rural show need left-right balance attention. The editor surfaces phase and balance controls as soon as a clip opens, so there is no menu hunting between cuts.
Working inside a networked workflow
Australian broadcasters rely heavily on shared storage and remote working. RƎLAY treats sessions as files that travel, which suits a freelance producer in Hobart sending cuts back to a network hub in Canberra without losing edit decisions.
The platform pairs naturally with Power Core and Ruby consoles, letting a station engineer place the editor exactly where the workflow needs it. Studios already using VisTool can extend that flexibility into the visual layer. For stations distributing audio across multiple web properties, a useful primer on redirecting domain traffic shows how a single canonical URL can be enforced without losing existing listeners. Export paths preserve metadata that matters downstream, including timestamps and segment markers used by automation.
Tailoring the visual workspace
A clean waveform display only earns its keep if it matches how a producer reads a file. RƎLAY lets users pick colour palettes, zoom presets, and keyboard maps suited to either a fast-paced newsroom or a slow documentary unit. Producers coming from older systems like SADiE map their muscle memory across within an hour.
The metering beside the waveform draws from the same engine that powers VisTool, so loudness targets set for Australian broadcasting standards stay consistent from edit to on-air. Studios wanting finer control over the visual layout can follow the guide on how to create custom metering layouts in VisTool for broadcast engineers and apply the same ideas to the editing surface.
A useful touch: the editor docks into a second monitor while the host stays on the primary display. Studios running four-screen desks in Pyrmont or South Bank favour this layout, and it works just as well on a kitchen-table laptop in Geelong.
Adapting the workflow for Australian broadcasters
Regional budgets and licensing shape how Australian broadcasters choose tools, and RƎLAY covers the range. A community station in Darwin runs it without the licence overhead of a full DAW, while a Melbourne newsroom scales it into a wider Lawo install backed by Power Core.
Hot-climate realities matter too. Studios in Cairns and Townsville deal with humidity that wears out outboard gear, so a software-centric editing path is a quiet win. The same applies to fly-away kits built for cricket on the road, where a heavy editing rack is a hassle through airport checks.
Stations bringing on new producers usually start with one workstation and a familiar template, then extend as staff grow confident. The team at Lawo walks Australian clients through deployment and licensing through their contact page, the most reliable starting point for studios weighing the switch.
Putting it all together
The most useful habit when cleaning interview audio is to work in passes rather than chase one perfect sweep. Start with structural cuts, then dial in breath management, finish with light de-noising and gain shaping. Each pass leaves an undo trail, so returning to a cleaner baseline is straightforward if processing is overshot.
For any Australian broadcaster sitting on a backlog of messy interviews, the practical takeaway is to open the longest file first and let the waveform editor's display drive the pace. Producers who trust the visual map of the audio ship cleaner packages faster, and that speed keeps regional bulletins on time and metro talkback rolling without stray phone artefacts bleeding into the next break.
