Pixel pixel pro Audio Eraservijayasarathy91mobiles

Just when the smartphone industry seemed to have plateaued in terms of innovation, a new leak suggests Google is preparing to redefine mobile audio editing with its next flagship. The upcoming Google Pixel 9 Pro is rumored to introduce a powerful new feature called Audio Eraser, thanks to a detailed leak by noted tipster Vijayasarathy on 91mobiles. If the leak is accurate, this feature could place Google once again at the forefront of AI-powered smartphone functionality.

With Audio Eraser, users may be able to remove unwanted sounds from recorded videos — background chatter, passing traffic, or wind noise — directly on their phones, without using third-party software. This development is more than just a cool new tool — it could be the start of a broader evolution in how mobile devices handle audio.

Let’s explore everything we know so far about Audio Eraser, the implications of this leak, and how it ties into Google’s long-term vision of AI-first smartphone computing.

The Leak: First Hints from Vijayasarathy via 91mobiles

The leak, first reported by Vijayasarathy (Eraservijayasarathy91mobiles), includes what appears to be early screenshots of the Audio Eraser interface within the Google Photos app. The screenshots show a waveform editor with identified audio segments — things like “Traffic,” “Voices,” or “Wind” — along with a UI that lets users mute or reduce these sound layers with a simple tap or slider.

According to the report, Audio Eraser is expected to debut on the Pixel 9 Pro, which is set for release later in 2025. It will reportedly rely heavily on on-device AI, likely powered by the upcoming Tensor G4 chipset.

91mobiles has a solid track record of credible leaks, especially when it comes to Google’s Pixel series, and Vijayasarathy has previously shared accurate pre-release details of features like Magic Editor and Photo Unblur.

What Exactly is Audio Eraser?

Imagine this: You’re filming your child’s birthday party in a crowded park, and someone starts mowing the lawn in the background. In most cases, that video would be permanently marred by the noise. But with Audio Eraser, you could potentially isolate and remove the lawnmower sound, leaving only the laughter, voices, and background music.

Audio Eraser is an AI-powered noise-removal tool that allows users to:

• Identify multiple audio sources in a video file

• Isolate specific sound types (e.g., wind, traffic, chatter)

• Delete or reduce selected sounds without affecting the main audio track

This isn’t your basic noise reduction filter — it’s intelligent audio segmentation, likely combining Google’s years of work in speech recognition (from Google Assistant and Recorder app) with machine learning models that differentiate between types of background noise.

How Does It Work? (Speculative Tech Breakdown)

While the leak didn’t provide technical details, we can make informed assumptions based on Google’s existing capabilities:

1. Sound Source Identification: The system likely uses AI to detect different audio frequencies and patterns. Similar to how Google’s Recorder app can identify different speakers, Audio Eraser might label and tag various sound sources.

2. Spectrogram Analysis: Behind the scenes, the phone could be generating a spectrogram — a visual representation of audio frequencies over time. The AI would then allow users to mute or reduce specific areas of that spectrogram.

3. AI Compression and Separation: Using on-device AI, powered by the Tensor G4 chip, the tool could separate the target sound from the mix while preserving the rest of the audio.

4. Machine Learning Models: Google has previously trained models to distinguish human voices from environmental sounds. These models could be at the core of Audio Eraser.

Most importantly, all of this is expected to run on-device, meaning your videos are processed securely without needing to upload them to the cloud.

Why Audio Eraser Is a Big Deal

This isn’t the first time we’ve seen audio editing tools, but this would be the first time such a powerful, context-aware tool is built directly into a smartphone’s photo/video editing suite.

Here’s why it matters:

1. Pro-Grade Editing for Everyone

Currently, removing unwanted sounds from videos typically requires advanced tools like Adobe Audition or Premiere Pro — tools not everyone knows how to use. Audio Eraser democratizes this process, making pro-level sound editing accessible to all.

2. Content Creators Rejoice

Whether you’re a YouTuber, TikToker, or mobile filmmaker, clean audio is essential. With Audio Eraser, creators can capture high-quality videos in less-than-ideal environments and fix the sound later — no expensive mic setups needed.

3. Reduces Need for Accessories

Currently, many mobile video creators rely on external microphones and deadcats to reduce noise. If Audio Eraser works as promised, users could achieve similar results with just their phone.

4. Privacy and Security

Since the feature processes audio locally, users won’t have to worry about their private videos being uploaded to third-party servers for editing.

How It Compares: Audio Eraser vs. the Competition

Here’s how Audio Eraser might stack up against other noise-reduction tools currently available:

Will It Be Pixel 9 Pro Exclusive?

This remains a critical question. If Audio Eraser requires the Tensor G4 chip and high-end hardware, it may be limited to the Pixel 9 Pro and perhaps Pixel Fold 2. However, Google has previously rolled out its AI features to older Pixels after initial exclusivity.

There’s a chance Audio Eraser could come to Pixel 8 Pro users in a future Feature Drop, albeit with performance limitations or longer processing times.

Broader Implications for AI and Mobile Editing

Google’s focus on on-device AI aligns with its broader mission to make smartphones more intelligent and autonomous. With features like:

• Magic Eraser (photo cleanup)

• Photo Unblur

• Live Translate

• Recorder’s smart transcription

…the Pixel is rapidly becoming the most AI-rich smartphone ecosystem available. Audio Eraser, if it lives up to the hype, could solidify Google’s position as the king of intelligent content editing on mobile.

It also raises an interesting question: will Apple respond with something similar in iOS 19?

What’s Next?

With Google I/O 2025 fast approaching, all eyes are on whether Audio Eraser will be officially unveiled during the keynote. Based on past behavior, Google may use I/O to showcase the technology before launching it with the Pixel 9 Pro in October.

Expect demo videos, live presentations, and plenty of AI talk as Google continues to push the Pixel series as the gold standard for smart devices.

Conclusion

The Audio Eraser leak by Vijayasarathy via 91mobiles might seem like a small feature at first glance, but it represents a major leap in mobile audio technology. If this tool works as advertised, it could change how millions of people capture and edit their everyday moments.

Just as Magic Eraser redefined our expectations of photo editing, Audio Eraser could do the same for sound — and that’s music to every content creator’s ears.
