SnowSky Tiny A EQ app for Android
Contour EQ is a free, open-source Android app that reads and writes the parametric EQ stored inside the SnowSky Tiny A. The EQ is written into one of the dongle's USER slots, so it works in every app, with no system equaliser.

What Contour does not do on the Tiny A
- Firmware updates.
- Resetting the DAC. The Tiny A (firmware 1.2.0) ignores the reset command, so Contour has no FACTORY RESET for it.
- Changing USB AUDIO. The DAC page shows it, but Contour does not change it.
Contour EQ and FiiO Control
FiiO's own tools for the Tiny A are the FiiO Control app and FiiO's web app. Contour's DAC page has the settings FiiO Control lists for the Tiny A: VOLUME, VOLUME STEPS, BALANCE, IN-LINE MIC and LIGHT. FiiO Control also lists USB AUDIO, which Contour shows read-only, and Restore default settings, which Contour leaves out because the DAC ignores the command. Contour runs on the Android phone the dongle is plugged into, keeps your profiles in a library on the phone and needs no internet or account.
Using Contour with the Tiny A
- Pick USER1, USER2 or USER3 above HOLD TO SEND. Contour writes the profile to that slot, checks it and makes it the active one. A shorter profile is filled up with flat bands, because the Tiny A always holds ten.
- After you plug the Tiny A in, Contour reads every USER slot by switching to each one, then goes back to the one that was playing.

Questions about the Tiny A
Is there an EQ app for the SnowSky Tiny A on Android?
Yes. Contour EQ reads and writes the Tiny A's 10-band EQ and preamp in its USER slots from an Android phone. It is free and open source (Apache 2.0). FiiO's own tools for this DAC are the FiiO Control app and FiiO's web app.
Can Contour update the Tiny A's firmware?
No. Contour does not update firmware. It reads and writes the EQ, the preamp and the settings on the DAC page, and shows the firmware version at the top of the DAC page.
Do I need a driver or root?
No. Android supports USB audio dongles out of the box, and Contour talks to the Tiny A over USB after you allow it in Android's permission prompt. No root, no extra driver.
