The Samsung Galaxy S25 Ultra's Audio Eraser Can Eliminate the Screeching Howls of the BART

Jan 27, 2025 - gizmodo.com
The article discusses the Galaxy S25 Ultra's AI-powered Audio Eraser feature, which allows users to adjust audio levels in videos by analyzing and separating different sound types, such as "noise," "wind," and "voices." The feature is designed to reduce background noise, like a child's screams or BART's screeching, and enhance voices in noisy environments. However, the author notes that while the tool can be useful for minor adjustments, it is not suitable for extreme edits and can result in poor audio quality if overused.

The author shares their experience using the Audio Eraser on a video recorded during a BART ride, where the feature struggled to clearly separate and enhance voices amidst the noise. The result was a garbled audio reminiscent of early cellphone calls, suggesting that the tool may not perform well in very noisy situations. Overall, the Audio Eraser is seen as an enhancer rather than a problem solver, useful for subtle improvements but not a replacement for high-quality audio recording.

Key takeaways:

  • The Galaxy S25 Ultra’s AI-powered Audio Eraser can adjust sound levels in videos, such as reducing background noise or enhancing voices.
  • The feature is useful for minor audio adjustments but not suitable for extreme edits or noisy environments.
  • Audio Eraser analyzes audio tracks and allows users to adjust layers like "noise," "wind," and "voices."
  • Overuse of the feature can result in poor audio quality, similar to a garbled cellphone call from the 2000s.
