What Stream What You Hear is

Stream What You Hear (SWYH) is a free, open-source Windows application that captures audio playing on a Windows PC and sends it across the local network to compatible TVs, amplifiers, speakers, and media players. It finds UPnP/DLNA Media Renderers on the same network and can start or remotely control playback on those devices. SWYH also provides direct HTTP stream URLs for compatible players. Audio can use MP3 or uncompressed PCM/L16, depending on the receiving device. Its Record page saves computer audio as an MP3 file while displaying live levels and recording duration. The PC and playback device must share a local network; SWYH does not use Bluetooth. Media Players require playback to be started on the device itself. DLNA buffering can create delay determined largely by the receiver. SWYH began in 2012, became open source in 2015, and was rebuilt as SWYH 2 in 2026. Version 1.5.0, published 19 May 2020, is listed as the latest stable release, while 2.0.0-beta.30 is a pre-release that may contain bugs. The maker identifies Sébastien Warin as creator and maintainer.

Who it suits

It suits Windows users who want to send computer audio to compatible networked playback devices or save it as MP3. It is also relevant to users with UPnP/DLNA equipment on a shared local network.
