Local library Folder scans, SQLite library storage, tags, cover cache, and album grouping for large collections.
Local library / Native output / Long-term care
Local HiFi ECHO Next
An open-source desktop music player for local libraries, HiFi output, and long-term maintainability. Library scans, covers, lyrics, queueing, and native audio output stay in clear boundaries.
02 ◇
Native output WASAPI Shared / Exclusive, ASIO, sample-rate state, and bit-perfect hints with a clear signal path.
03 ▣
Cloud library Supports SMB, Navidrome, Baidu Netdisk, and other remote library sources while keeping network files inside a clear playback boundary.
04 ✎
Diagnostics Logs, crash recovery, library health, cache migration, and settings backup make issues traceable.
Library, full scale
From folder scanning to album walls, from tags to cover cache, ECHO Next treats large-library browsing as a core capability. Screenshots are from the real app, not staged promo art.
Folders, album wall, songs, likes, history, and playlists are organized around local files.
System output, WASAPI, ASIO, EQ, preamp, and sample-rate state each have a clear place.
Renderer handles UI; main process and native hosts own playback, scans, cache, and system integration.
What ECHO actually does
Not an empty shell. A local-music and DSP control center.
The homepage should surface the real product: local library, native output, professional DSP, lyrics and MV, remote sources, plugins, and diagnostics built for long-term use.
Local music stays first
Folders, songs, album walls, artists, inbox, likes, history, playlists, and duplicate checks are organized around local files instead of online-platform assumptions.
- SQLite library
- Cover cache
- Tag reading
- Large-library browsing
Professional DSP is not decoration
ECHO Next turns EQ into a real DSP workspace: DspChain, headroom, safety limiting, FIR room correction, channel balance, spatial calibration, OPRA headphone correction, and APO import/export live in one explainable chain.
- DspChain
- Headroom
- FIR / IR
- OPRA
A signal path you can read
System output, WASAPI Shared / Exclusive, ASIO, ReplayGain, sample-rate state, and bit-perfect hints each have a clear place; DSP is marked when active, and native direct path stays clear when it is off.
- WASAPI
- ASIO
- ReplayGain
- Bit-perfect state
Lyrics and MV stay controllable
Local lyrics, online candidates, translations, romanization, kana enhancement, per-track offsets, and MV matching live in a flow that users can correct.
- Candidate matching
- Translation display
- Lyric offsets
- External playback boundary
Remote is an extension, not a lock-in
WebDAV, Jellyfin, Emby, SMB, SSHFS, Subsonic, Navidrome, and cloud sources can enter the same browsing and playback experience without replacing local ownership.
- SMB / WebDAV
- Jellyfin / Emby
- Subsonic
- Remote indexing
Expandable without losing boundaries
Plugins, downloaders, network metadata, streaming search, and remote background tasks run behind controlled permission and task boundaries.
- Permission model
- Plugin logs
- Import / export
- Task boundaries
Problems should be traceable
Logs, crash recovery, library health, cache migration, settings backup, and dangerous-action confirmation give long-term maintenance a practical escape route.
- Log export
- Cache migration
- Health checks
- Settings backup
Recommended path
From the first track to the full library.
ECHO Next is not about switching everything on at once. It behaves more like a stable desktop setup: confirm local playback first, then add output, lyrics, remote sources, and plugins.
- 01 Start with a small folder
Confirm scan, artwork, playback, and lyrics before importing the whole collection.
- 02 Shape the browsing view
Use songs, albums, artists, folders, inbox, and history to recover the collection map.
- 03 Tune the output path
Choose system output, WASAPI, or ASIO, then check sample-rate and bit-perfect state.
- 04 Add experience layers
Bring in lyrics, MV, artwork, metadata, remote sources, downloaders, and plugins when needed.
UI, lists, lyrics, MV, settings, and player controls.
Controlled API boundary between UI and native power.
Scans, SQLite, cache, plugins, remote sources, and diagnostics.
WASAPI, ASIO, device state, low-latency output, and recovery.
