The measurements

Same song in. Two effects out. Compared side by side.

We play the same recording through the Galaxy S8/S9 tube effect and through Amp S Again, align both outputs to the sample, and compare them. Every chart below uses the drum solo from the player above.

One kick drum, up close

120 milliseconds of the actual waveform, from the excerpt you can play. The flat sound goes its own way; Amp S Again stays on the S8/S9's line through every swing.

0 – 120 ms

Drag across the waveform to zoom in · the vertical scale follows the zoom · double-click to zoom back out.

How we measured: identical music goes into both effects; outputs are aligned to the sample. Amp S Again contains no Samsung code.

Questions

Good to know.

Is Amp S Again made by Samsung?

No. Amp S Again is an independent product. It is not affiliated with, endorsed by or sponsored by Samsung Electronics. We compare it with the Galaxy S8/S9's tube effect because many listeners miss that sound.

Does Amp S Again contain any Samsung code?

No. Amp S Again is written from scratch and tuned with measurements of how the phone's effect changes real music.

What do I need?

A 64-bit Windows 10 or 11 PC. Amp S Again installs a small virtual audio device so your sound can pass through the effect on its way to your speakers.

Does it work with Bluetooth headphones?

Yes. Pick them in Amp S Again's tray menu. Each output keeps its own EQ curve and level, so switching between headphones and speakers needs no re-tuning.

Will videos stay in sync?

Amp S Again adds about a tenth of a second of delay with the standard buffer, which is usually unnoticeable in videos. If lips and sound drift apart, free browser extensions fix it by shifting the picture to match the sound. We use LagSync (Chrome and Firefox), which works on YouTube, Netflix and most web videos. Bluetooth Video Sync and Audio Bluetooth Sync are alternatives. A longer buffer is also available for difficult Bluetooth connections.

Can I switch it off?

Any time, with one click on the tray icon. Your sound then goes straight to your speakers.
