Tag: Version 2

Fixes some GUI logic regressions and some other minor bugs.

Some fine tuning of DSD7 modulator. Number of small fixes.

Redesigned DSD7 modulator plus number of fixes and improvements in various different areas.

First experimental release of full HQPlayer Desktop for ARM platform is now available for the SolidRun CuBox.

Fixes a 2.9.0’s regression in the half-band down-sampling algorithm and in the convolution engine.

Significant performance and small quality improvement in the poly-sinc down-sampling algorithm. Now the poly-* DSD-to-PCM converters can run on almost any machine and are now the most recommended way when conversion is needed. Two new delta-sigma modulator variants. The “dual-wire” DoP 1.1 DSD128 (0x06/0xF9) is now supported with both WASAPI on Windows and ALSA on…

HQPlayer Desktop 2.8.4.3 for Windows available to fix a playback start problem on Windows 8 WASAPI with some device drivers.

Optional high frequency expansion algorithm for the convolution engine. New resampling / oversampling algorithm “poly-sinc-hb”. Improved parallelization for multi-core processors. Initial support for Windows 8. Many small usability improvements.

Fix for a possible crash and rework of ALSA back-end to support wider range of audio hardware.

Improved volume control for DSD content. Fixed a playlist loading issue with certain M3U8 format playlists. Option to ignore all warnings about certain complex conversion ratios.

Rewritten minringFIR filter, now available also as oversampling filter in the delta-sigma modulator. Support for convolution engine in PCM-to-SDM conversion case. Button to invert absolute phase. Number of other fixes and improvements.

Experimental support for “dual wire” mode on Linux to reach 384 kHz PCM and 128x SDM rates over dual AES links or channel-per-I2S with standard rates on other interface types. Also includes various fixes. For other changes, see earlier beta announcements.

Special handling for DSDIFF/DSF files in playlist mode to avoid clicks/pops between unrelated tracks. Remembers last used directory of all file dialogs. Small fix for DSF file handling. A lot of small changes.

HQPlayer Desktop for Linux updated to 2.7.3.1 to solve some issues and add support for Fedora (16) distribution.

This release includes a new trial period. Numerous changes, including redesigned UI, support for playlists (pls/m3u or adding files/trees to an internal playlist), support for mixed rate transports, support for native/direct playback of DSDIFF/DSF files using different “PCM packing” schemes (Linux&WASAPI), fixed issue on native DSF playback. Significant rework of one-bit audio to PCM conversion…

Plus update for the openSUSE version.

New product split into Desktop, Embedded and Engine SDK versions. Completely reworked volume control and soft limiter. DAC bits setting for those with non-24-bit DAC behind unidirectional connection like S/PDIF or AES/EBU. Experimental “non-ringing” polynomial interpolation. And some bug fixes from the beta.

Now includes 64-bit Desktop version, improved installer, dropped network licensing support. Due to changes in directory structure and shortcut naming, uninstall older version before installing this to avoid broken shortcuts and abandoned files!

Small GUI improvements and further noise shaper tunings for NS4 and NS9.

Better handling for paths without supported files, installer and manual updates.

Fixes crashes with certain slightly buggy ASIO drivers. Also fixes incorrect total remain value in some cases as well as contains some further tunings in NS1 noise shaper.

Fixed a newly introduced first-time installation startup problem the in desktop version. If you are experiencing this problem, either download this new version, or first start embedded version, go to Settings, click OK and then start the desktop version… No need to update if you have 2.5.3 desktop version already working.

Improvements for RIFF (WAV) files with more than 24-bit resolution, fix sample bit indication and other minor changes. Fixed a default settings problem introduced in previous version. Better handling for “basic” mode and improvements in a way mode switching is done.

Fixed problems in non-mapped network share handling and minor problems in RIFF (WAV) handling. Improved ASIO support. Improved performance in FIR resampler and DSDIFF/DSF file playback. Re-tuned noise shapers and dithers. Improvements in installer. Also contains “basic” and “advanced” modes for the main screen.

Included ASIO support in Desktop version, further tuning in poly-sinc* resamplers, completely reworked FFT-resampler and other minor improvements and fixes. Network licenses available on request for existing customers. Configuration file can be specified as a commandline parameter.

Fixed a startup issue on some Windows 7 systems, support for metadata parsing from file path, changes in the desktop GUI, support for multiselect in transport/paths list, support for DSF file format, improved sound quality for DSDIFF/DSF file playback, fixes in RIFF (WAV) handling, preliminary support for (non-compressed) multichannel DSDIFF/DSF files, plus set of minor…

Available on special request and for system integrators. If you would like to see a generic release, please vote by sending an email!

Minor update, more optimizations to the desktop version to make it consume less CPU power. Now the desktop version can play DSDIFF-files on equally slow CPU as the embedded one.

This is a major update, includes release version of the desktop and embedded versions! Various fixes and new features, most notably support for WAV (RIFF) playback, support for any sampling rate for convolver impulse responses, new desktop UI with high quality digital volume control, selectable convolution engines, configurable gain compensation for the convolution engine, etc,…

Now includes a beta version of a new desktop/laptop UI! Installation of the new UI is optional; it is WASAPI-only and available only as 32-bit at the moment, but included in all installation packages. (Note! Startup of the desktop version may take a while!)

Collection of small fixes, including small correction for the poly-sinc gain calculation.

This release contains improved unicode support and a fix for 32-bit float WAV impulse response files. You may need to regenerate transport list.

Added new key bindings and improved transport list editor.

Now hardware buffer length defaults to driver default. Also includes convolution engine fixes related to non-minimum-phase impulse responses. Overall performance of the convolution engine has been improved.

Fixed a bug in soft limiter (used for material containing clipped peaks).

Changed transport list layout a bit for better readability, no other changes.

Complete reimplementation of polyphase resampler, now capable of converting between most typical rates at very high quality. Also includes minimum phase variant. New feature for adding entire directory tree into the transport list. (File – Paths – Add tree…)

Fixed a recently introduced bug in no rate conversion case.

Fixed a problem on creating user settings directory and updated the manual. Otherwise same as the beta.

Small modifications on minimum-phase sinc-resampler; improved pass-band SNR on slight expense of stop-band attenuation. Also performance optimizations on sinc-resamplers and slightly different handling for media keys.

Some bugfixes and support for up to 768 kHz sample rates.

Second wave of bugfixes. Most notable fixes include a fix for recently introduced IIR filter breakage as well as fix for dither selection. As a new feature, this release contains significantly better load balancing for multicore CPUs.

Bugfix release, including internationalization fixes as well as new path selector for transport editor.

Contains minor fixes and driver workarounds compared to last beta. Try 48/96 kHz rates on HD-Audio adapters if you get silence with other rates…
