You've probably noticed that pulsing soundwave animation on Reels with original audio—and wondered whether it's just visual flair or a genuine ranking signal. Let's dig into what that animation actually means for your Reels performance, and whether you should be chasing it as an Australian creator.
What the soundwave animation actually tells Instagram
The soundwave appears when you've uploaded a Reel with original audio that Instagram hasn't indexed as a trending sound. It's essentially a visual indicator that you're the first—or among the first—to use that particular audio clip. The animation itself pulses in sync with your audio waveform, creating that dynamic visual on the Reel thumbnail.
Here's what matters: the soundwave doesn't directly boost your ranking. Instagram's algorithm doesn't award bonus points simply for having that animation visible. What it does signal is originality, and that's where things get interesting for watch time and retention metrics.
Original audio tends to perform differently than trending sounds. When you use a trending sound, viewers often arrive with pre-set expectations—they've heard it dozens of times, they know the format, they're primed for a specific type of content. Original audio means you're creating something fresh, which can work strongly in your favour if your content is genuinely engaging, or backfire if viewers bounce because they don't recognise the audio cue.
The real question isn't whether the soundwave itself helps—it's whether original audio strategies align with how Australian audiences engage with Reels content right now.
How original audio affects Australian Reels performance
Australian creators have a distinct advantage with original audio, particularly when incorporating regional humour, local references, or authentic voiceovers with Australian accents. The soundwave often appears on:
- Voiceover Reels where you're narrating tips, telling stories, or walking through a process
- Behind-the-scenes content with ambient sound from your location
- Original music or comedy sketches you've created yourself
- Screen recordings with your own commentary
The key performance factor isn't the animation—it's whether your original audio holds attention better than a trending sound would for that specific piece of content. According to Buffer's 2026 data, Australian Reels posted between 6-8pm AEST on weekdays see peak engagement, which means your original audio content hits feeds when audiences are actively watching with sound on during evening scroll sessions.
If you're testing original audio performance, check your insights against your baseline. You can audit your overall engagement rate to establish what "normal" looks like for your account size. For context: nano creators under 10K typically see median engagement of 5.0%, while healthy performance sits around 7.0%. If your original audio Reels consistently outperform that baseline, you've found something that resonates.
When to choose original audio vs trending sounds
Use original audio when:
- Your content relies on specific voiceover or narration that carries the value
- You're creating educational or tutorial content where your voice guides the viewer
- You're building a recognisable brand voice or personality
- Your niche is location-specific to Australia (real estate tours in Sydney, Melbourne café reviews, regional travel content)
- The trending sounds in your niche feel oversaturated
- You're participating in a format that requires that specific audio for context
- Your visual content is strong enough to hold attention without original narration
- You're trying to ride discoverability from a rapidly trending sound
- Your target audience actively searches for content using that audio
The soundwave animation naturally appears in the first scenario, but remember: it's a byproduct of your audio choice, not the goal itself. If you're saving competitor Reels for reference or inspiration, you can download any Reel without the watermark to study their audio choices and format structures more closely.
Testing original audio: what to track
If you're experimenting with the soundwave approach, here's what actually matters in your Insights:
Watch time and retention curve: Original audio Reels should show strong retention through the first 3 seconds and maintain it through your key message. If viewers are dropping off immediately, your audio isn't hooking effectively—even if the soundwave looks dynamic.
Shares and saves: These weighted actions matter significantly more than likes. Instagram's formula values saves at 3x and shares at 4x the weight of a standard like. If your original audio content drives viewers to share it with friends or save it for later, that's a stronger ranking signal than any animation.
Audio page visits: Check whether anyone is clicking through to use your audio. If even a handful of accounts adopt your original sound, Instagram starts treating it as potentially trending, which can boost your Reel's distribution retroactively.
Sends per reach: This metric shows how often your Reel gets sent in DMs relative to how many people saw it. High-quality original audio—especially relatable voiceovers or clever commentary—tends to drive strong send rates because it feels personal and shareable.
For Australian creators targeting local audiences, consider whether your original audio uses regional language or references that resonate specifically with Australian viewers. A voiceover mentioning "servo" instead of "gas station" or timing references to AEST creates subtle cultural alignment that can improve retention with your core audience.
The hidden advantage: audio page ownership
Here's something most creators overlook: when you create original audio that others use, you own that audio page. Every Reel made with your sound links back to your account. This becomes incredibly valuable if even one of those secondary Reels goes viral.
Australian creators have seen success with:
- Original comedy voiceovers about local experiences (public transport chaos, weather extremes, café culture)
- Niche tutorial narration in industries with strong Australian presence (tradie tips, property content, surf/beach safety)
- Regional music snippets that tap into Australian music culture
You can check whether creators in your niche are experimenting with original audio by using the hashtag library to research trending tags in your space, then manually reviewing top-performing Reels for that soundwave indicator.
Making the call for your content strategy
The soundwave animation itself won't make or break your Reels performance. What matters is whether original audio serves your specific content better than trending sounds would.
Test both approaches strategically: Run original audio on content where your voice, narration, or specific audio adds genuine value. Use trending sounds when you're creating visual-first content or participating in established formats. Track your engagement rate across both categories—you can calculate your weighted engagement using the proper formula that counts likes x1, comments x2, saves x3, and shares x4.
For Australian creators posting according to optimal local timing, original audio performs best when your audience is actively watching with sound enabled—typically evening hours when commuters are scrolling on public transport or winding down at home.
The soundwave might catch a viewer's eye as they scroll, but it's your first three seconds of actual content—original audio or not—that determines whether they stay for the full watch. Focus on that retention, and the ranking signals will follow naturally.
