Mixxx: baixar versions anteriors

We're proud to announce a new stable release of Mixxx: version 2.5.6. This version contains updates and fixes for issues, as well as improvements to effects, controller mappings, and overall stability. This should be the last 2.5 release. Note that this version is the successor of version 2.5.4 because version 2.5.5 has been skipped following an issue in the release workflow. We'd like to thank all users for their feedback and emphasize once again the importance of testing and reporting. Please join our team to help make Mixxx even better.
Enjoy Mixxx!

Mixxx 2.5.3 Release Announcement: Back to School, back to DVS.
We're proud to announce a new stable release of Mixxx: version 2.5.3, this version not only contains updates and fixes for some issues reported by users, but it also contains improvements to the Digital Vinyl System (DVS) support. These improvements are the result of some bright new insights of developers spinning the wheel instead of sunbathing. Since these improvements drastically improve the vinyl experience, we have chosen to backport 1 it to the 2.5 series instead of integrating it in future alpha & beta versions.
Have a nice Mixxx.
Digital Vinyl System - Timecode System.
An introduction to Digital Vinyl Systems and timecode can be found in this article on the site of Digital DJ Tips, and in our own news archive: How Does Timecode Vinyl Actually Work? (Pt. 1), How Does Timecode Vinyl Actually Work? (Pt. 2) and How Does Timecode Vinyl Actually Work? (Pt. 3).
Mixxx plays the song by following the signal on the timecode media, which gets internally converted to actual timeframes. So the DJ controls the playback of the digital music by manipulating vinyl or CDs.
In order to create a vinyl-like feeling, the song needs to follow the signal as closely as possible (low latency, fast responsiveness) for e.g. scratching or backspins. There is no 'standard' signal - each manufacturer uses its own code. One thing all manufacturers have in common is that the code is modulated onto a sine wave. The code is used for absolute positions e.g. after needle drops, but it is not suitable to handle pitch (e.g. the playback speed) or playback direction. For this the sine wave needs to be processed by a filter that detects phase differences and converts it into pitch information.
Mixxx has integrated the xwax library for timecode support, which uses an Alpha-Beta Filter for pitch detection. This filter provides a good feeling during scratching, but isn't able to provide a stable pitch during normal playback. In PR #15194 developers have replaced the Alpha-Beta Filter with a more advanced Kalman-Filter equivalent.
Kalman-Filters have many application as GPS navigation and weather forecast models. In Mixxx the Kalman-Filter uses a probabilistic model of the vinyl movements to predict the velocity, very similar to the Alpha-Beta Filter. This predicted speed is compared with the noisy crackling input signal. The deviation 2 is fed back into the filter and slightly alters its internal state for the next prediction.
If the vinyl is, say, spinning at 33 1/3 r/min, that value is used as the initial assumption on which the next prediction is based. If the next measurement returns 40 r/min, the value is not fully trusted, because such a high acceleration is unlikely. This measurement will be used with a low trust. However, if the following measurements detect 40 r/min as well, the filter gradually adjusts to approximate 40 r/min in further predictions.
By using this model, Mixxx is able to properly and more accurately represent e.g. the pitch control slider on the turntable or CD-player.
Another improvement has been made to the measurements which are fed to the Kalman filter PR #15217. The current model only takes rough measurements of the position on the sine wave. Furthermore these measurements work on the assumption to always be correct. A new check was added to detect if measurements were skipped or larger than assumed. This improves backspins where the deviation of estimation and measurement suddenly become very high.
These changes are major improvements for all DVS users. Too good to wait for Mixxx 2.6.

Winter and Summer are coming
Contrasts. As the leaves fall and the first snowflakes start drifting down in the North, while the southern skies start warming up with summer sun, we are thrilled to finally release Mixxx 2.4.2! "Finally" because a bit later than planned, perfection can take some time. So we are proud to present you this release, a major bugfix-release for the 2.4 series before stepping over to a new number. Don't be scared, development won't hibernate.
Testing and translating
A special thank you to everyone who takes the time to test alpha and beta versions, to who report issues and proposals and to those who propose features and improvements. Your feedback is invaluable. A lot of new users and contributors have joined our community the past months, we'd like to welcome them all, spin it up, your energy and fresh ideas have already left a mark. Everybody can contribute to Mixxx. Did you find an error on the website, an incomplete subject in the manual, an error in translation?
Contribute.
Treasure hunt
When you dive into the code to add a feature or when you are looking for a function when you want to customize a mapping, you can discover small little snippets, real pearls, the intensive work of someone to make a function smoother, to let an algorithm work some milliseconds faster, to offer a conversion of a value to another without having to write it all over again. For all these little snippets, for all these forgotten pearls: thank you to all who ever contributed.
What's in the 2.4.2-bag?
