“Compare two audio tracks with just one tap of a button.”
You upload 2 audio files (A and B).
If you want, you add labels (e.g., “pre”, “post”, “ref”, “v2”).
You click OK, LET ME HEAR.

You press and hold the button — you hear the second track switched live.
You release — you instantly return to the first one.
This approach is intentionally minimalist:
zero distractions, maximum listening.

Demos by Black View Studio (ready examples)

To show what it’s about right away, Black View Studio prepared 2 of our own demo files straight after mastering, connected to the compare buttons. These are ready examples — you can click and test without uploading, to hear in practice how A/B works in tap & hold mode.

Why it matters for mastering engineers (and mixers)

AudioToggle’s biggest advantage is instant switching without breaking context.

That makes it easier to catch differences in:

• kick/bass lock (sub, punch, low-end control),
• midrange clarity (vocals, leads, guitars),
• top end (air vs harsh),
• stereo/mono (width without pulling the center apart),
• dynamics (when “louder” doesn’t mean “better”).

Typical use cases

• master v1 vs v2 (revisions),
• before/after (pre-chain vs post-chain),
• reference vs your version,
• export comparisons (e.g., different limiters / different settings).

Pro tip (honest A/B)

Match loudness — louder almost always sounds “better” at first.
Compare short sections and one parameter at a time (low end / top end / stereo).
Do quick A ↔ B switches instead of listening through to the end.

Feedback and support

There’s also a small nod to the community: if you feel the tool saves you time, you can support it symbolically (“tip a mate”). And if you have ideas or something isn’t working — there’s a “Have some issues or ideas?” button that sends you to feedback (Discord).
