Coming soon A complete engineered audio suite for local music

A complete Android audio engine.
Inside a music player.

Seedling Music Premium is built around a self-contained native realtime DSP graph engineered as part of the player itself. Graphic and parametric EQ, bass processing, Spatial 3D, reverb, ReplayGain, headphone crossfeed, convolution/FIR, Hi-Res output control, resampling, dithering, truthful bit-perfect handling, profiles and live diagnostics sit alongside the full Seedling visual system and optional Google Drive music sync.

Seedling Studio • Premium audio architecture

Advanced Android audio processing.
Engineered as one native signal path.

Premium's sound system is a coordinated processing graph owned by Seedling. Audio is processed in the player's native PCM path, with the signal chain, output policy and diagnostics designed together so the controls behave as one engine rather than unrelated vendor effects.

For listeners who want more than a basic Android equalizer, Premium brings up to 20-band parametric EQ, ReplayGain, headphone crossfeed, convolution/FIR, Hi-Res processing, resampling, dithering and output diagnostics into one integrated signal path.

≋

Graphic EQ + up to 20-band parametric EQ

Use the quick five-band Studio curve or build a detailed PEQ with Bell, shelf, low-pass, high-pass, notch and band-pass filters. Each PEQ band can target stereo, left or right channels, with frequency, gain and Q control plus preamp and automatic headroom management.

Bass, Spatial 3D and Seedling reverb

Dedicated low-frequency enhancement, adjustable spatial soundstage processing and an app-owned ambience engine with room size, decay, damping, pre-delay, diffusion and wet/dry control.

ReplayGain with clipping protection

Track or album ReplayGain can normalize listening levels using metadata-aware gain, optional preamp and peak-based clipping prevention—integrated into the same processing graph.

Headphone crossfeed

Blend controlled opposite-channel energy with adjustable strength, cutoff and delay to soften extreme hard-panning and create a more loudspeaker-like stereo image for headphones.

Convolution / FIR impulse processing

Load an impulse response into Seedling's convolution engine, control the mix and process it as part of the realtime native path. The engine also tracks convolution latency as part of playback topology.

Hi-Res processing and output policy

Choose native rate, 2×, 4×, 8× or maximum-supported upsampling, select resampler quality, prefer float PCM output and choose TPDF or noise-shaped dithering. Bit-perfect mode is reported only when Android accepts an exact final-PCM output match on a supported route.

Studio bypass and profiles

Compare processed and original signal with A/B bypass, save the larger Studio state as profiles, and recall sound choices without rebuilding them every session.

▥

Live DSP diagnostics

Premium can inspect the active native signal path: processor activity, RMS differences, limiter reduction, applied settings, resampler state and convolution status. It is engineered to verify what the engine is actually doing, not merely what a switch says.

Fail-open playback philosophy

Studio is designed so an unavailable native DSP component does not make the player unusable: original playback remains the priority. Bit-perfect mode also disables incompatible processing instead of pretending altered PCM is still bit-perfect.

Premium feature catalog

Not a badge.
A genuinely larger player.

The audio engine is only one half of Premium. The current build also unlocks a substantially larger visual and interaction system: themes, artwork-derived themes, playback controls, seekbars, album-art styles, visualizers, action rows, timer actions, control depth, widget controls and premium assets.

Google Drive, not a Seedling cloud locker

Files go to the Google Drive account you authorize. Seedling Music Premium does not grant copyright rights to the music you upload.

Official-purchase verification

Premium uses Google Play Integrity and a server-signed entitlement so Premium capabilities are tied to a valid official Google Play installation and purchase. Cached entitlement supports normal offline use between verification windows.

Premium without weakening the Free edition

Separate package.
Separate capability boundary.

Seedling Music Premium uses package com.seedling.music.premium. Its premium feature catalog and assets remain separate from the Free build, protecting the intended distinction between the editions.

Premium audio engine FAQ

For listeners who want
deeper control of the signal path.

Direct answers about the parametric EQ, Hi-Res processing, ReplayGain, crossfeed, convolution and other parts of Seedling Music Premium's native audio engine.

Does Seedling Music Premium have a parametric equalizer?

Yes. Premium supports up to 20 parametric EQ filters with Bell, shelf, low-pass, high-pass, notch and band-pass options. Bands can target stereo, left or right channels with frequency, gain and Q control.

Does Premium support ReplayGain, headphone crossfeed and convolution/FIR?

Yes. ReplayGain, configurable headphone crossfeed and convolution/FIR impulse processing are integrated into the same native realtime DSP graph rather than being presented as unrelated external effects.

What does Hi-Res processing mean in Seedling Music Premium?

Premium provides output-policy controls for native-rate or higher-rate processing, multiple resampling quality levels, float PCM preference and TPDF or noise-shaped dithering. Actual device output still depends on Android, the connected route and hardware capabilities.

Is bit-perfect playback always active?

No. Premium reports bit-perfect mode only when the final PCM path can genuinely remain unaltered and Android accepts the required output conditions on a supported route. Incompatible processing is disabled rather than being mislabeled as bit-perfect.

Is Seedling Music Premium designed for audiophile-style listening?

It is designed for listeners who want unusually deep, inspectable audio control on Android: parametric EQ, ReplayGain, crossfeed, convolution, resampling, dithering, output policy and live DSP diagnostics are all part of the engineered signal path.

How is Premium different from a separate Android equalizer app?

The audio engine is built into Seedling's playback path. Processing order, headroom, output policy, convolution latency, A/B bypass and diagnostics are coordinated as one system instead of relying on a chain of unrelated device effects.

Can Seedling Music Premium sync music with Google Drive?

Yes. Premium includes optional Google Drive music sync using the limited drive.file scope and a dedicated Music folder, with upload, restore, Wi-Fi and automatic-sync controls.

Premium privacy

Cloud features are
explicit, not hidden.

Premium's privacy policy separately covers Google Drive authorization and music sync, Play Integrity/license verification, optional Last.fm, artwork and lyrics services, plus local app data.
