Why Audio Pros Choose A/B Players
Professional-grade comparison tools that make your work speak for itself
Instant Switching
Toggle between A/B versions in under 5ms with zero audio gap — or set a smooth crossfade up to 2 seconds. Your listeners hear the difference immediately.
Lossless Quality
Full lossless fidelity for accurate comparisons — no compression, no degradation. Fast streaming available for instant playback.
Equal-Loudness Comparison
Optional loudness matching plays versions at equal perceived volume, so the comparison is about quality — not "the louder one sounds better." Your files are never modified.
Share Anywhere
Generate embed codes or direct links. Works on websites, social media, emails, and more.
Track Engagement
See how many times people listen and toggle. Understand which version resonates more.
Customizable Design
Match your brand with custom colors, fonts, and 6 different player layouts.
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.
