Large local libraries Folder scans, SQLite storage, tags, cover cache, album walls, likes, and playlists built around local files.
Local-first HiFi, made to last
Local HiFi ECHO Next
An open-source desktop player for serious local libraries and HiFi output: scanning, tags, artwork, queueing, native output, and a professional DSP chain, all done properly on the desktop.
02 ◉
Native output chain System output, WASAPI Shared / Exclusive, ASIO, sample-rate state, and bit-perfect hints each have a clear entry.
03 ◇
Professional DSP center Parametric EQ, FIR room correction, OPRA headphone correction, and channel tools in one explainable chain.

Not just playback. A complete music workstation.
ECHO Next puts scanning, tags, artwork, lyrics, queueing, remote sources, DSP, output devices, and diagnostics into one readable chain. It is not an online-platform shell; it is built for real local collections.
Songs, album walls, artists, likes, history, and playlists serve one local collection.
System output, WASAPI, ASIO, HQPlayer, and sample-rate state each have a clear place.
Lyrics, MV, remote sources, and plugins add capability without scattering the main flow.
Logs, crash recovery, cache migration, and settings backup keep long-term use stable.
DSP Center
A readable workstation for serious audio processing.
Signal path, module state, tonal shaping, headphone correction, FIR room correction, and output safety share one control surface. Clear when processing, clear when back on the direct path.
Input, sample rate, shaping, spatial processing, and output state form a visible signal path.
Headroom, preamp, Auto Gain, and clipping risk are part of the flow, not hidden parameters.
Simple mode keeps everyday tone shaping approachable; Pro remains for precision work.
Parametric EQ, FIR / IR, OPRA, channel tools, and APO import/export, enabled layer by layer.
ECHO Audio Lab
More than playback: a transparent digital signal path.
ECHO SRC and ECHO SDM serve different output goals: one handles PCM sample rates, while the other explores PCM-to-SDM conversion. Both prioritize visible state, device matching, and safe fallback.
PCM · Sample Rate ConversionAvailable now
ECHO SRC
A local PCM sample-rate conversion path. It follows the 44.1 kHz and 48 kHz rate families, with selectable quality, filtering, and low-latency strategies.
- PCM input
- ECHO FIR / SRC
- Target rate
- DAC
DSD · Sigma-Delta ModulationTechnology preview
ECHO SDM
An experimental PCM-to-SDM path separate from PCM and native DSD passthrough, combining oversampling, filtering, modulation, and noise shaping for supported DACs.
- PCM input
- Oversampling / FIR
- Sigma-Delta
- DSD / SDM
Recommended path
From the first track to the full library.
The route is not "switch everything on": confirm stable 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, likes, and history to recover the collection map.
- 03 Tune the output path
Choose system output, WASAPI, ASIO, or HQPlayer, then verify sample rate and bit-perfect state.
- 04 Add experience layers
Bring in lyrics, MV, artwork, metadata, remote sources, and plugins when needed.
Manual
Many features, explained clearly
Install, library, audio output, DSP, HQPlayer, remote sources, plugins, and troubleshooting each have a documentation entry. The homepage shows the range; the docs explain the boundaries.

Bring every music capability within reach.
Local files, NAS, WebDAV, Jellyfin, DSP, lyrics, MV, and plugins live in one experience. ECHO Next organizes, plays, and routes them so the collection feels close again.
