SurroundStreamer v0.1.1

SurroundStreamer v0.1.1

Deliver live music and multichannel audio in surround.

SurroundStreamer v0.1.1 is the current release for macOS and Windows. It sends audio from an audio interface or audio file to an Icecast/Shoutcast-compatible streaming server as Ogg Opus surround audio, stereo MP3, or both.

Use it for live music, spatial-audio playback, surround stream testing, and multichannel file streaming. Monitor output, channel templates up to 7.1, and KU100 near-field HRIR preview help you check the stream before and during playback.

Linux support is in preparation, but no Linux package is published in this release.

Platform Notes

macOS

• Supported target: macOS 14.2 or later on Apple Silicon.
• Audio Input capture uses the packaged Core Audio helper.
• File source uses the packaged FFmpeg file-input path.

Windows

• Supported target: Windows x64.
• Audio Input capture supports native ASIO and MMDevice/WASAPI paths.
• DirectShow is available as a fallback when the native helper is unavailable.
• For surround Audio Input streaming on Windows, use an ASIO-capable audio interface or ASIO virtual audio device with 6 or more input/output channels.

Linux

• Linux packages are not published for v0.1.1.
• Linux support is planned around a future native Linux audio backend.
