SECIA Music Player

Your files, straight to the DAC. A player that doesn't gloss over anything.

SECIA Music Player plays the music files stored on your device. No ads, no subscription, one purchase. Instead of promising "great sound," it shows you the path your audio actually takes, and where anything gets converted along the way.

■ The signal path, on one line

The player screen always shows the route from file to DAC.

Example: FLAC 24bit/96kHz → Exclusive → USB DIRECT

Source format, output mode, destination — left to right. If a conversion happens, the changed value is shown as it is. A guide to reading the line is included in Settings.

■ Bit-perfect playback

Designed to deliver the original bit stream to your DAC without conversion. Whether it is actually getting through untouched is something you can check on the signal path line for every track. When your device or OS forces a conversion, that is shown too, not hidden.

■ Direct output to USB DACs

A built-in driver sends audio straight to your USB DAC over the USB DIRECT path, bypassing the Android audio mixer — so no OS resampling or volume processing sits in the way. Works with portable and desktop DACs, and on supported DAPs you can choose ALSA direct to reach the internal DAC.

■ DSD playback

Play DSF and DFF files via native DSD, DoP, or PCM conversion. DSD64 through DSD512 are supported, and the quality of PCM conversion is selectable. Choose the method that suits your DAC.

■ Supported formats

FLAC / ALAC (m4a) / WAV / AIFF / MP3 / AAC / DSD (DSF, DFF)

Playlists: m3u and m3u8. Gapless playback supported.

■ Choose your own output path

Pick from USB DIRECT, AAudio / OpenSL ES, AudioTrack, and ALSA direct. Automatic selection is the default, but you can switch by hand when a device behaves badly. Buffer length, output bit depth, and bypassing the device's own DSP are all adjustable.

■ Diagnostics

"Run diagnostics" performs a self-test, an endurance measurement, and a buffer-length sweep in sequence, then recommends settings for your hardware. Apply them with one tap. Playback records are kept on the device so you can review them later.

■ Library

Browse by folder, album, artist, or genre. An index rail lets you move through large libraries quickly. Tags and artwork are displayed.

■ Appearance and languages

40+ color themes, including deep-black schemes suited to OLED screens. Available in 15+ languages.

■ Also

- Chromecast sending is supported (DSD excepted).

- No ads. No account required.

- One-time purchase. No in-app purchases or subscriptions.

■ Before you buy

- This is a player for music files stored on your device. It does not play streaming services.

- Using a USB DAC requires USB host support (USB OTG) on your device.

- What actually reaches your DAC depends on your device, its OS, and the DAC itself. Results are not identical on every model, and this app will show you when a conversion has been applied.

- Whether a DAC accepts native DSD depends on its implementation. For DACs that do not, use DoP or PCM conversion.
