Welcome to the easiest local-first audio forwarder designed to fix low volume, muffled sound, or broken laptop speakers instantly.

Why stream PC audio to your phone instead of using a Bluetooth speaker?
-
Bypasses Weak or Broken Laptop Speakers: Instantly solve low volume limitations by converting your phone into a loud, high-fidelity external wireless speaker system. (You can also plug headphones into your phone if you prefer private listening).
-
Eliminates Audio Lag & Lip-Sync Issues: Standard Bluetooth connections often suffer from severe audio lag, making movies completely unwatchable. By using a standard charging cable to enable USB Tethering, this tool pushes the audio stream over a physical wire for a zero-latency movie watching experience.
-
Network Agnostic (Wi-Fi or Hotspots): This tool works seamlessly across any shared local network layout. It connects instantly whether your devices are on home Wi-Fi, hotel Wi-Fi, or directly connected via a mobile hotspot hosted by either device.
-
100% Private Peer-to-Peer Streaming: Adhering to a strict local-first data architecture, your captured audio uses WebRTC technology to transmit data locally. Your system sound stays entirely on your own network and never touches an external internet cloud server.

Boost Low Volume & Fix Poor Laptop Speakers
Is your laptop speaker too quiet, crackling, or completely broken? Instead of straining to hear your videos, this free browser-based tool allows you to convert your mobile phone into a loud wireless speaker for your PC audio instantly. It effectively turns your smartphone into an external sound system to bypass weak computer audio, though you can always plug in headphones if you prefer private listening.
Unlike complicated third-party software, this utility relies entirely on modern browser capabilities. It captures the audio from your specific web browser tab (like YouTube, Twitch, or a local MP4 file opened in Chrome) and forwards it directly to your smartphone's built-in speaker. If you are looking for an app to use phone as pc speaker via wifi or a laptop to mobile audio streamer to fix low volume issues, this zero-installation web tool handles it flawlessly.
Pro Tip for Movie Watchers: While local Wi-Fi or hotspots work great for casual listening, video playback requires perfect lip-sync to compensate for weak computer audio. By enabling USB Tethering on your Android or iPhone and connecting it to your computer with a standard charging cable, this tool pushes the audio stream over a physical wire, eliminating wireless lag completely.

Frequently Asked Questions (FAQ)
Do I need to install an app on my phone or laptop?
No. This tool runs entirely within your web browsers. You do not need to install any software, virtual audio cables, or mobile applications.
Why am I getting no sound?
The most common issue is forgetting to check the "Share tab audio" checkbox when the browser asks you which tab to share on the laptop. Additionally, some mobile browsers block autoplaying audio. If you don't hear anything, tap the "Tap to Unmute/Play Audio" button that appears on the phone screen.
Why does Netflix or Amazon Prime show a black screen / no audio?
Browsers use DRM (Digital Rights Management) to prevent piracy on premium streaming sites like Netflix, Disney+, and Hulu. When a browser detects that you are capturing the tab, it automatically blackouts the video and mutes the audio track. This tool works best for standard web video (YouTube, Vimeo, Reddit) or local video files dragged into your browser.
How do I fix audio lag/latency?
If the audio is slightly behind the video, it is due to your Wi-Fi router. To fix this, connect your phone to the laptop with a USB cable, go to your phone's connection settings, and turn on USB Tethering. Refresh this page and connect again. The audio will travel over the wire instantly.
