Your music deserves the truth.
Bit for bit. Untouched.
You've invested in high-resolution recordings, in a good DAC, in headphones that reveal every detail. And then the player quietly downsamples the signal, re-clocks it, pushes everything through a mixing pipeline you never asked for. FLAC, DSD, studio masters — treated like an MP3 from 2004.
On top of that, the management madness: one program for playback, one for tone, one for metadata. Each with its own logic, its own learning curve. And in the end it still doesn't sound the way it was recorded.
MuSéa does it differently.
MuSéa is a high-res audio player that respects the signal. Bit-perfect all the way to the hardware — no hidden resampling, no secret processing. Pro-grade output via WASAPI Exclusive and ASIO, DSD and hi-res natively. An equalizer when you want it — cleanly bypassed when you don't. SoundRay shows what your files actually deliver. And a library that finally puts your collection in order.
No need to run three programs in parallel. No driver settings to decode. You pick the source — MuSéa delivers exactly what's on the recording. Bit-accurate. Untouched. The way it was meant to be.
Everything for true sound
Eight promises, uncompromisingly focused on the signal — each one better in its own way.
🎯 Uncompromisingly bit-perfect
Your signal reaches the DAC unchanged – no resampling, no hidden tone shaping.
🔊 Pro output: WASAPI Exclusive & ASIO
A direct line to the hardware, selectable buffer size, exclusive access – the way studios do it.
💿 DSD & hi-res, natively
DSF/DFF over DoP, high-resolution formats, internal float64 processing.
🎛 EQ & convolution – only if you want
Parametric EQ, tone controls and room/headphone correction. Off = guaranteed bit-perfect.

🔒 Your data stays yours
Local library, freely chosen storage location, one-click backup & restore.
Uncompromisingly bit-perfect
MuSéa's output pipeline adds nothing and removes nothing — and it's honest: it doesn't claim to be bit-perfect, it proves it. The key part: you never have to toggle a DSP mode anywhere. With the volume at unity (0 dBFS) and no tone processing active, the decoded samples go to the DAC unchanged. The moment you turn the volume or use the EQ, the engine switches automatically and seamlessly into 64-bit processing — no menu, no checkboxes.
An engine that delivers what it promises.
Real bit-perfect playback all the way to the DAC, driver-hardened WASAPI Exclusive negotiation, a dedicated ASIO path and bit-exact DSD over DoP. Processing — if at all — in 64-bit precision with a single, cleanly dithered quantization right at the end.
Bit-perfect without switching
No DSP switch, no settings menu. At unity gain and with no tone processing, the signal goes to the DAC unchanged. Turn the volume or enable the EQ and the engine automatically and seamlessly switches into 64-bit processing — and back again.
WASAPI Exclusive & ASIO — driver-hardened
Instead of trusting the often dishonest format reports of DACs, MuSéa tries the formats by real init in priority order. If exclusive fails, there's an honest shared fallback — clearly marked as "not bit-perfect". ASIO as a dedicated path with selectable buffer size.
DSD & hi-res, bit-exact
DSD over DoP truly bit-exact — with a dedicated exclusive renderer and a device guard against noise on non-DoP DACs. High-resolution PCM all the way up to studio masters, without downsampling.
Quantized exactly once
An exemplary signal chain with processing in 64-bit precision and exactly one cleanly dithered quantization right at the end. Volume works strictly below 0 dBFS — software never amplifies above full scale and therefore can't clip.
⚙ Technical details
- Adaptive paths
- Three separate paths: bit-perfect pass-through · 64-bit float DSP · resampling
- Automatic path switching based on volume and DSP state — no manual toggling
- Soft 45 ms fade on path change so nothing clicks
- Signal chain
- Source → EQ → convolution → crossfeed → volume → limiter → [resampling] → dither → PCM
- EQ before volume: a boost is cleanly pulled back below 0 dBFS
- Quantized exactly once — right at the end of the chain
- Output backends
- WASAPI Exclusive with driver-hardened format negotiation (real init instead of a mere format query)
- Honest shared fallback, clearly shown as "not bit-perfect"
- ASIO as a dedicated path with selectable buffer size and a clean track end
- DSD
- DoP bit-exact for DSD64 / 128 / 256 / 512, dedicated exclusive renderer
- Device guard against noise on non-DoP DACs
- Volume & dither
- Volume in 64-bit float, hard-limited to ≤ 0 dBFS — no clipping from amplification
- 30 ms ramp against zipper noise
- TPDF dither (textbook-correct), deliberately omitted at 32-bit
- Formats
- PCM: FLAC, ALAC, WAV, AIFF up to 32-bit / 384 kHz
- DSD: DSF, DFF
- Lossy: MP3, AAC, Ogg Vorbis, Opus
The EQ – built from scratch
The equalizer is the heart of MuSéa — deliberately comprehensive, yet surprisingly easy to use thanks to its many graphical views and modes. The guiding principle throughout development was an organic, musical character: adjustments sound natural, never technical.
Parametric, precise, musical
A fully parametric EQ with graphical curve control, on a biquad basis with 64-bit precision. Presets with 5, 7 or 10 bands — freely expandable and placeable anywhere. Bell, shelf, high/low pass (12 / 24 / 48 dB/oct.) and notch, in minimum- or linear-phase.
Clipping-safe by design: the intelligent auto-gain keeps the summed curve guaranteed below 0 dB — and even without it, an optimized anti-clipping algorithm keeps levels stable. For full control you also have a manual pre-gain (−24 … +12 dB).
Plus: global bass/mid/treble controls, crossfeed for headphones, balance with stereo level metering, import of free correction profiles and convolution with your own impulse responses. Switchable look between LED spectrum and frequency curve. The EQ can also be shown directly in the playback view as an embedded view.

A library that protects your files
Four equal browse axes, freely configurable tables, a full metadata editor with pro fields — and a safety principle collectors will love: every change first lives protected in the app database, your original files stay untouched.
Your original files stay untouched.
"Write to file" is off by default for every edit. Each change — tags and cover art — first goes only into the app database and merely overlays the file tags in the display. Only when you deliberately choose to are the tags actually written into the audio file. So edit your collection completely worry-free — and even assign tile cover art to artists and compilation albums that can't exist in any file.
Four browse axes, one workflow
Albums, artists, genres and tracks are equal entry points — no menu is "the main path". A sidebar holds favorites and any number of named, persistent playlists. Clever display filters per axis go well beyond simple sorting, and each axis remembers its sort order separately: switching between album and artist never loses your setting.
🧭 Browsing, filters & sorting
- Browse axes & sidebar
- Albums, artists, genres, tracks as equal entry points
- Sidebar with favorites and several named, persistent playlists
- Display filters per axis
- Album axis: "Album" (flat list) ⇄ "Album artist" (grouped)
- Artist axis: "Artist" (artist tag) ⇄ "Album artist" (AlbumArtist tag)
- Sort order is remembered separately per axis and stored persistently
- Sorting
- Albums: title · year · track count · total duration · quality
- Artists: name · track count · album count · total duration
- Ascending/descending; track table sorts on column-header click, click empty = default
▦ Table columns — freely configurable
- 17 selectable columns
- Title, artist, album artist, album, composer, genre, year, track no., disc, comment, format, quality, sample rate, bit depth, bitrate, duration, path
- Handling
- Arrange via drag & drop, freely resizable width, selection persists
- Default: title · artist · album · quality · duration
🏷 Metadata editor
- Editable fields
- Title, artist, album artist, album, genre, composer, comment, year, track no./count, disc no./count
- Pro fields
- Sort name (e.g. "Beatles, The"), grouping, BPM, rating 0–5 stars, compilation flag, leading zeros for track/disc number
- Multi-editing of several tracks at once
- Read automatically
- Format, lossless flag, sample rate, bit depth, channels, bitrate, duration
🛡 Database protection & cover art
- Safe editing
- "Write to file" off by default — changes first go only into the app database
- DB changes overlay the file tags in the display only; original files stay clean
- Deliberately enable → tags are actually written into the audio file (incl. cover art, separated into album and album-artist cover)
- Cover art beyond the file
- Custom tile cover art even for album artists and albums that can't exist in any file — stored in the DB only
- DB cover takes precedence over the embedded file cover
- Performance
- Thumbnail cache (thumbs.db) for a fast cold start of the tiles
- Favorites are persisted separately
Your music. Your galaxy.
With MuSéa, playlists become a universe. Every playlist appears as a glowing nebula in the starfield — arrange freely, resize, zoom in. You no longer sort music into lists, you shape it.
Constellations
Connect nebulae into constellations. A drawn line of light links two worlds: the direction sets the playback order, a closed circle plays endlessly. Each nebula can shuffle on demand — individually, as a group, or the whole galaxy at once.
Orbits
Evenings become orbits. From the jazz nebula into the eighties and back — one double-click, and your constellation starts to circle.
MuSéa — the audiophile player that makes your music glow.
Your data stays yours
The library is stored locally, at a freely chosen location. No forced account, no mandatory cloud. With one-click backup and restore you secure your collection and bring it back anytime.
