Eversolo OTA V1.5.90 – evotune Pro, Boundless Display and New Music Library for DMP Series, PLAY Series and T8

A mature streaming platform is defined not only by the hardware on which it runs, but also by how consistently its software develops over time. With OTA V1.5.90, Eversolo Audio Technology Co. Ltd. is addressing several central aspects of its ecosystem at once, extending compatible products from the Eversolo DMP Series, Eversolo PLAY Series and the Eversolo T8 with nine new functions, 21 optimisations and five stated bug fixes. The most prominent additions are evotune Pro, browser-based control through Boundless Display and a fundamentally redesigned Music Library. Considerably more control over CD ripping, experimental cached streaming and a long list of detailed refinements make the release one of the more consequential updates to the Eversolo platform.

evotune Pro – More Sophisticated Room Correction and Sound Tuning

One of the headline additions in Eversolo OTA V1.5.90 is evotune Pro. According to the manufacturer, this extended version of its room-correction system improves the measurement process, filter calculation and the options available for tailoring the resulting sound.

Users can define their preferred listening position, select an appropriate measurement microphone and load the corresponding microphone calibration file. On this basis, evotune Pro is intended to assess the acoustic influence of the room more precisely and provide more targeted adjustment for the loudspeakers, their placement and the actual listening position.

This considerably broadens the role of room correction within the Eversolo platform. Rather than serving solely as a straightforward corrective feature, evotune Pro is designed as a more comprehensive tool for methodically tuning the entire audio chain to the listening environment.

Boundless Display – Control Directly from a Web Browser

Boundless Display extends the user interface of compatible Eversolo products to computers and tablets. It can be accessed directly through a web browser, provided that the browser device and Eversolo component are connected to the same local network.

Access is established using the Eversolo device’s IP address and port 9599. The address is entered in the format IP address:9599, for example 192.168.1.33:9599. No additional application or dedicated software installation is required.

The larger working area should prove particularly useful when browsing extensive music collections, editing metadata or assembling longer playlists. Boundless Display therefore complements both the touchscreen built into many Eversolo products and the Eversolo Control app with another practical operating option.

Additional Vintage VU Meter Styles

OTA V1.5.90 also expands the visual options available for the Now Playing screen. Users can choose from additional Vintage VU Meter styles, including traditional pointer instruments and designs developed specifically by Eversolo.

These displays naturally have no influence on signal processing or sound quality. On products equipped with a large front-panel display, however, they form a conspicuous part of the user experience and allow the visual presentation to be matched more closely to personal taste or the surrounding HiFi system.

Far More Control over CD Ripping

CD ripping receives one of the most extensive revisions included in Eversolo OTA V1.5.90. Users can now define an individual reading strategy, including the reading speed, the number of repeated passes and the comparison of multiple reading results.

A precise offset adjustment has also been added. Track numbers can be placed automatically at the beginning of filenames, producing a structure such as 01 – Track.flac. The system can additionally inspect previous ripping processes and compare an audio CD with existing ripping logs, even when the associated files have subsequently been moved to a different folder.

FLAC compression can be selected from Level 0 to Level 8. Higher settings require more processing time during file creation but reduce storage requirements without changing the lossless nature of the audio data.

Once a rip has been completed, the system can generate a report automatically. Eversolo also states that album-art retrieval has been improved. Taken together, these changes provide considerably more control over reading accuracy, file naming, compression and documentation.

A Rebuilt Architecture for the Eversolo Music Library

Another fundamental change concerns the Eversolo Music Library. According to the company, both its underlying architecture and the logic used to manage data have been revised.

The new implementation is intended to shorten loading times, improve navigation and handle large local music collections more efficiently. Album and artist sorting have also been adjusted, which should be particularly relevant to users managing substantial libraries stored locally or accessed across a network.

The familiar views for tracks, artists, album artists and composers remain available. The difference is intended to lie not merely in how quickly these views appear, but also in the way the underlying music data is processed and organised.

Pull-to-Refresh for File Lists and Indexing Status

Complementing the rebuilt Music Library, OTA V1.5.90 introduces a pull-to-refresh gesture. Swiping down refreshes file lists and the current indexing status directly within the relevant view.

New, deleted or modified content can therefore be reflected more quickly without opening a separate menu or leaving and re-entering the current screen. It is a modest addition in technical terms, but one that should make routine library maintenance noticeably more immediate.

Online Playback Using a Local Cache

OTA V1.5.90 also introduces cached playback for online content. When enabled, streaming data is stored temporarily in a local cache before playback, helping to bridge short-term variations in network performance.

Eversolo explicitly labels this function as experimental. It can be enabled under Settings > Playback or Playback Settings > Cached Streaming Playback, depending on the interface in use.

Its effectiveness will inevitably depend on the network connection, streaming service and available data rate. The underlying approach is nevertheless sound: if enough audio data has already been buffered locally, brief reductions in network throughput need not interrupt playback immediately.

Playback and Buffer Status at a Glance

To accompany cached streaming, Eversolo has expanded the progress bar on the Now Playing screen. In addition to showing the current playback position, it now indicates which sections of a track have already been buffered.

Yellow or white identifies content that has already been played, depending on the selected display theme. Light grey represents audio held in the buffer, while grey marks sections that have neither been downloaded nor played.

The additional information is available when Cached Streaming Playback is active. It provides a direct visual indication of how far a track has been preloaded and whether the buffer contains sufficient data to compensate for an unstable network connection.

Clearing Playback History from the Play Queue

The Play Queue gains a previously missing housekeeping function. Tracks that have already finished playing can now be removed manually without clearing or rebuilding the entire queue.

A delete icon at the top of the view initiates the process. Following a confirmation prompt, the previously played tracks are removed while the remaining queue stays intact.

21 Optimisations for Playback and Music Management

In addition to its nine new functions, Eversolo OTA V1.5.90 contains 21 optimisations. These affect major areas such as room correction, the Music Library and CD ripping, as well as many smaller aspects of everyday operation.

The optimisations cover:

• Room-correction performance
• SMB sharing
• CD ripping
• Playback through Enjoy Music
• Global favourites
• Global search
• Retrieval of album information during CD playback
• Starting large playlists through the File Manager
• Genre assignment in the Music Library
• Artist recognition and processing
• Adding complete albums to the Play Queue
• Retrieval of ID3-tag information from local audio files
• Importing large files into the Music Library
• Display of multiple artists
• Presentation of playback details
• Radio playback
• Detection and integration of UPnP devices
• Resetting the local Music Library
• Playlist import and export
• Processing of CUE files in the File Manager
• Retrieval of images for artists and composers

Resetting the local Music Library now removes only the data directly associated with that library. Other system areas and settings remain unaffected.

Bug Fixes for LMS, Music Services and Playlists

Eversolo states that OTA V1.5.90 contains five bug fixes, although the detailed information supplied for the update identifies four individual corrections.

The documented fixes address an issue that could occasionally cause LMS to become unresponsive, while music services should now refresh automatically after a login session has expired. The track count shown for global playlists is also corrected after songs have been removed.

In addition, adding an album from the Music Library to the Play Queue should no longer cause it to start playing immediately when no such command was intended.

The Main Benefits at a Glance

• More precise room correction: evotune Pro expands the measurement process, filter calculation and individual sound adjustment.
• Operation on a larger screen: Boundless Display provides browser-based control from a computer or tablet.
• Faster music management: The rebuilt Music Library is intended to navigate and process extensive collections more efficiently.
• Immediate updates: Pull-to-refresh updates file lists and indexing information without leaving the current view.
• Greater control over CD ripping: Reading strategy, offset, FLAC compression and file naming can be configured individually.
• More stable online streaming: The experimental local cache can help compensate for temporary fluctuations in network performance.
• Visible buffer status: The extended progress bar shows which parts of a track have been loaded or already played.
• Improved everyday operation: Search, favourites, metadata handling, the Play Queue and UPnP have all received targeted refinements.

Price and Availability

Eversolo OTA V1.5.90 is available now as a free firmware update for compatible products in the Eversolo DMP Series and Eversolo PLAY Series, as well as the Eversolo T8. The installation can be initiated directly through the integrated OTA update function of the respective device.

Conclusion

Eversolo OTA V1.5.90 is considerably more than a collection of minor corrections. evotune Pro, Boundless Display and the rebuilt Music Library address three central parts of the platform: sound optimisation, system control and the management of personal music collections. The expanded CD-ripping facilities and experimental streaming cache respond to very specific practical requirements, while the 21 optimisations refine many functions that users encounter every day. With this release, Eversolo Audio Technology Co., Ltd. delivers a substantial platform update that should be relevant both to owners of large local libraries and to listeners who primarily rely on online streaming services.
