Instant Playback, Lossless Quality
Why choose between speed and fidelity? SoundToggle gives you both.
Large lossless files can take time to load — especially on mobile or slower connections. Fast Streaming solves this by loading a lightweight proxy stream the moment your listener presses play. The full lossless file loads silently in the background and hotswaps in seamlessly, with no interruption and no re-buffering.
Instant start
Playback begins in under a second, even for large WAV/FLAC files
Seamless upgrade
Lossless quality fades in automatically, zero interruption
Listener transparency
A quality badge in the player shows "Streaming → Lossless" in real time
Always your choice
Enable fast streaming globally, per-project, or not at all
Fast Streaming is completely optional. You can enable it globally from Settings, override it per-project (Always On, Always Off, or Use Default), or leave it off entirely. SoundToggle always serves lossless audio — Fast Streaming just gets your listener to "play" faster while the full-quality file loads behind the scenes.
