Google’s Pixel line has long been a benchmark for mobile innovation, especially in computational photography and AI-driven experiences. But a new leak from tech tipster Vijayasarathy (@vijayasarathy91mobiles) via 91mobiles suggests that the Pixel 9 Pro is about to break new ground — not with its camera, but with audio. The feature in question? Audio Eraser — a rumored tool that could revolutionize how we edit and experience sound on smartphones.
With Google I/O just around the corner, this leak couldn’t have come at a more tantalizing time. Here’s a deep dive into everything we know so far about the Audio Eraser feature, what it could mean for users, and how it stacks up against existing audio tools on the market.
What Is Audio Eraser?
According to the leak, Audio Eraser is designed to isolate and remove specific background sounds from videos recorded on the Pixel 9 Pro. Imagine shooting a video in a bustling street and later being able to erase car honks, chatter, or construction noise — leaving only your subject’s voice or the desired ambient sound. That’s the core promise of this feature.
The leaked screenshots suggest that Audio Eraser will live inside the Google Photos app, much like Magic Eraser — the popular tool that removes unwanted objects from photos using AI. Users will reportedly be able to scrub through the audio timeline, detect unwanted noise sources, and eliminate or minimize them.
How Will It Work?
While Google hasn’t officially detailed how Audio Eraser works, the leak indicates that the technology uses AI-powered audio segmentation and spatial sound recognition to analyze layers of sound captured in a video. This process is similar to how studio-level audio editors isolate frequencies to clean up recordings, but done locally and in real time — right on your phone.
The UI in the leaked images shows waveform visuals alongside audio detection zones. Users can select audio elements (e.g., traffic, crowd, wind), and the Pixel’s Tensor G4 chip — rumored to power the Pixel 9 series — will process and filter those elements.
If this sounds like magic, that’s because it almost is. Google has already applied similar tech in its Recorder app, which transcribes speech and allows users to search through specific words or speakers. Audio Eraser is essentially an evolution of that underlying tech, now focused on video content.
Why It Matters
Smartphones have become our primary tool for recording everyday life, from family moments to vlogs, travel content, and even mini-documentaries. But audio has always been the Achilles’ heel of mobile recording. Bad sound — whether from wind, traffic, or a noisy room — can ruin an otherwise perfect shot.
If Audio Eraser works as promised, it could dramatically raise the bar for casual content creators and professionals alike. Here are a few key benefits:
-
Vloggers and Creators: No need for external microphones or post-processing in apps like Adobe Audition.
-
Travelers: Clean up background noise from crowded tourist spots or noisy transit.
-
Students and Journalists: Record lectures or interviews in noisy environments and enhance speech clarity later.
-
Parents: Remove distracting sounds from your toddler’s first words or your dog’s funny moments.
The implications go beyond convenience. Audio Eraser represents a shift in how we think about mobile editing — putting tools once reserved for professionals into everyone’s pocket.
Comparison: How Does It Stack Up Against Existing Tools?
There are already a few apps and tools on the market that offer similar capabilities — at least in theory. Adobe’s Premiere Pro and Audition allow noise reduction, and apps like Dolby On or Krisp offer real-time noise suppression. However, they’re either cloud-dependent, subscription-based, or require more technical know-how.
What sets Audio Eraser apart is integration and simplicity. It’s expected to work within Google Photos, requiring no external app, and leverages on-device machine learning — meaning faster processing without compromising privacy.
Here’s a quick comparison:
| Feature | Audio Eraser (Pixel 9 Pro) | Adobe Audition | Krisp | Dolby On |
|---|---|---|---|---|
| On-device Processing | ✅ | ❌ | ❌ | ❌ |
| AI Sound Segmentation | ✅ | ✅ | ✅ | ❌ |
| Free for Users | ✅ (Expected) | ❌ (Subscription) | ✅ (Basic tier) | ✅ |
| Integration with Camera | ✅ | ❌ | ❌ | ❌ |
| Ease of Use | ✅ | ⚠️ | ✅ | ✅ |
What Vijayasarathy’s Leak Tells Us
The leak by Vijayasarathy included several screenshots and early impressions of the feature in action. While the source did not offer a video demo, the visual evidence seems convincing. One screenshot shows the system labeling background noises as “Traffic”, “Voices”, and “Wind”, while another shows a user interface slider to “Reduce Noise Intensity”.
Eraservijayasarathy91mobiles is known for reliable Pixel-related leaks, and Vijayasarathy has previously reported accurately on Pixel 8 Pro features like AI Wallpaper and Magic Editor.
In short: this leak is credible, and it seems Audio Eraser is more than just vaporware.
Will It Come to Older Pixel Devices?
One big question users are asking: Will this feature be exclusive to the Pixel 9 Pro, or will it roll out to older models like the Pixel 8 Pro or Pixel Fold?
While there’s no official word, early speculation suggests that Audio Eraser may require the upgraded Tensor G4 chip due to the heavy AI workload involved. However, Google has surprised us before — Magic Eraser was backported to older Pixels and even select non-Pixel Android phones (with Google One).
It’s likely that a lighter version of Audio Eraser may come to the Pixel 8 series, albeit with reduced performance or fewer sound targets.
Release Timeline and Availability
The Pixel 9 Pro is expected to debut at Google’s annual hardware event in October 2025, with a teaser potentially landing at Google I/O in May. If Audio Eraser is a flagship feature, we may see it highlighted alongside Android 15 enhancements and new AI services like Gemini Assistant.
Once launched, Audio Eraser will likely ship out-of-the-box on the Pixel 9 Pro, with an update to the Google Photos app enabling it. The feature could later be part of the Feature Drop updates, a strategy Google uses to roll out software enhancements over time.
Final Thoughts: Game-Changer or Gimmick?
If Audio Eraser performs as promised, it could be one of the most impactful audio innovations ever seen in a smartphone. We’ve grown accustomed to AI enhancing our photos — now it’s time for sound to get the same treatment.
Just as Magic Eraser became a viral sensation, Audio Eraser could become a must-have for every Pixel user and a serious draw for content creators looking for a streamlined editing experience.
Of course, the true test will be real-world usage. Can Google deliver studio-level editing on-device without latency or quality loss? If they do, the Pixel 9 Pro may not just be the best smartphone for photos — it could also become the best for sound.
Stay tuned as we wait for more details from Google. Until then, Audio Eraser might just be the quiet revolution we didn’t know we needed.
