FOR EVERYONE

[Play virtually every audio format in existence. Octopus scrapes and organises your library instantly, however large or chaotic. Lossless: FLAC, ALAC, WAV, AIFF. Lossy: AAC, MP3, M4A.]

FOR THE PURIST

[Your tracks, exactly as mastered. A bare-metal native DSP engine and a true bypass signal path deliver absolute integrity from file to ear. Nothing added. Nothing taken away.]

FOR THE PERFECTIONIST

[Sculpt your soundstage with a battle-style 3-band EQ driven entirely by native digital signal processing. Full frequency control, zero latency.]

FOR THE BOLD

[Two studio-grade FX engines turn your device into a live signal processor: Rave FX (French House, massive punch) and Punk FX (Raw, driven, unforgiving).]

FOR THE EXPLORER

[A custom-built genre intelligence engine runs locally. Every track is automatically classified using file metadata, a curated alias map, and a hand-built dictionary. It organises itself.]

FOR THE CURATOR

[Build and manage playlists the way you think about music. Drag, reorder, add entire albums or genres in one move. Everything stored locally, instantly available offline.]

FOR THE NOMAD

[A native C++ crossfeed kernel—the classic Bauer/Chu Moy topology—recreates the interaural delay and head-shadow your ears expect from speakers in a room, simulating studio monitors inside your headphones.]

FOR THE EXPERIENCE

[Feel the hardware. The interface is rooted in industrial design—Nixie tubes, hardware-calibrated VU meters, a mechanical ticker. An analog soul wrapped in digital metal.]

WAVEFORM

[Watch your tracks breathe through a high-frequency spatialized audiograph.]

FERROFLUID

[A live-rendering ferrofluid-like turbo-fps GPU-driven audio sculpture, forged in real time on bare metal.]
