A new road to music discovery lies ahead!

It’s been just about a year since I last wrote about search, so I figured it was a good time to provide an update on what’s been going on behind the scenes.

The Roon team has been working on improving the search engine throughout 2022, and last week, we rolled out a new architecture for search. If you are running Roon 2.0, you have been using the new stuff for several days.

Previously, the cloud performed a search of TIDAL/Qobuz libraries and the Core performed a search of your personal library, then merged the results.

Now, the Core gathers potential matches for the search query and submits them to a cloud service. The cloud service then searches the TIDAL/Qobuz libraries if needed, ranks and merges the results, and returns the final list to the app.

This change will allow us to deliver better results and improve the search engine more quickly. For more information, keep on reading.

Automated Testing Tools

One of the challenges of improving a search engine is understanding the effects of each change that we make. A change that improves one search might accidentally make other searches worse. In order to make progress, we need to be able to test our search system and understand the intended and unintended consequences of each change.

We introduced an automated testing system in 2022 to help us with that. This system allows us to test thousands of searches in the cloud without using the Roon Core. Our test infrastructure will help us make sure we’re not making things worse as we continue to improve the search engine.

Shorter Cycle Time for Improvements

By moving the search engine to the cloud, we can release improvements without shipping new versions of the Roon Core and apps. This reduces the time it takes to deliver improvements to our users, and allows us to iterate quickly on specific issues when they are reported.

Metrics

While our primary goal is to make our users happy, it’s also helpful to have objective signals that show we are making things better. The new search system includes an array of metrics that allow us to monitor search results quality on an ongoing basis. This helps us see if our changes are helping, and also helps us catch any accidental issues that might degrade the quality of search results for our users.

As an example, the “Average Click Position” metric measures the average position where a user clicks when they select an instant search result. For example, a result of ‘1’ means that the user selected the first item in the list.

These are the results from last week’s rollout. You can see that the number dropped quickly around the time of our rollout, which shows that our changes were an improvement.

Smarter Ranking

One of the challenges with the old search system was merging lists that had been ranked separately in the Core and in the cloud. It was difficult to compare scores from different ranking systems, so we relied on heuristics that tried to balance the ranks, popularity information, and text match accuracy.

This often led to less-than-ideal results, and troubleshooting issues was time-consuming because we had to replicate each user’s library in-house in order to see the issues. Since search ranking is now performed in the cloud in a unified way, this class of tricky issues has disappeared.

More Powerful Algorithms

Today, state-of-the-art search systems use Machine Learning to deliver results. It was difficult to use these techniques in the old Roon Core, so one of the main goals of the re-architecture was to enable this.

In the future, we will be able to tailor results to individual users. For example, a Beatles fan typing “John” into the search box probably expects “John Lennon” to be the top result, while a Jazz listener might expect “John Coltrane”.

This will also enable the implementation of modern search techniques like spelling corrections, search suggestions, semantic search, and gradient boosting, none of which are practical within the Roon Core.

Instant Search Improvements

After deploying the new architecture internally in September, we started the process of tuning it to perform better than the old system. We focused on improving the instant search dropdown, making sure that fewer characters are required to reach the desired result, and that the results continue to feel sensible as more characters are entered.

In addition to automated testing, we have a weekly review process where the product and search teams come together to examine a set of 50 representative searches and discuss how the results changed because of the previous week’s work. This helps us understand the tradeoffs and make decisions that prioritize the user experience.

Dozens of Smaller Improvements

As part of this work, we made many of smaller improvements to the search system. Shorter queries like “john” or “pink” should now return more coherent results. The system is not directly auto-correcting misspellings, but it is more tolerant of misspelled terms in multi-word searches. It is also better at prioritizing exact matches, deduplicating similar results, and choosing the best version of an album or track when there are multiple versions available.

While things have definitely gotten better in the past year, 2022 was mostly about laying the groundwork. We plan to make faster and more visible progress in 2023 and beyond.

I want to thank everyone for their patience as we work on improving the search engine, and for all the feedback in last year’s thread. It has been very helpful in understanding our users’ perspectives, and we hope you will continue to use our product and provide feedback in the future.

With our Fall 2021 release, you’ll see some great improvements to Roon, but the big news is that we’re rolling out the first of a series of fun web-based tools to our community of music fanatics. The goal of these tools is to let you contribute your expertise to Valence, our cloud-based data system, making the Roon experience richer for the whole community!

Art Director

Everyone benefits from better-looking artist photos and band logos, so we’ve created Art Director, the first in a series of fun web-based tools that puts Roon users in control of how artist images are shown in Roon. Using Art Director, you can adjust the positioning of artist photos, upload your own band logos and images, and vote for your favorites. By doing so, you’ll be helping the whole Roon community and making perfect artist images a reality.

How does Art Director work?

When you visit our new Valence page and select “Contribute”, you sign in with your Roon account and select Art Director. You’ll be presented with images from the Valence database that need your artistic eye. If you want to adjust images for a specific artist, just type their name into the search box. From there, you’ll see all of the adjustments contributed by other users, as well as any images that still need your direction.

Art Director allows us to be far more dynamic with the images used in Roon, giving us the ability to adjust photos to fit into specific shapes. For example, you can adjust the main image that is displayed at the top of an artist page, as well as their circular ‘avatar’ that is shown on the Artists page and within search lists. This means no matter where an artist image is displayed in Roon, it will always look fantastic. If you have a band logo or a photo of an artist that you love, you can also upload it to Art Director to be featured in Roon. 

You and the rest of the Roon community can also vote for your favorite image on an artist’s page. Just click on the heart next to any adjusted image; this is how Valence decides which images are shown in Roon. As the Roon community begins to vote and adjust artist photos, you’ll always see the best possible images in Roon, and they’ll constantly improve based on the efforts of our community.

Local image edits are still possible, but if you have previously spent time improving artist images in your own library, you can now make these changes in Art Director to update your library while improving the Roon experience for everyone.

To start contributing, just sign into Valence using your Roon account details at valence.roonlabs.com

Playlists by Roon

Our team lives for music, and it’s our goal to create the best experiences for other music lovers. In addition to Roon itself, we do this by collaborating with artists, our community, and with our own music team to bring you editorial content and playlists that we think you’ll enjoy. Over the past year we’ve worked with artists including Patricia Barber, Daymé Arocena, AHI, and Stephen Moccio to bring you exclusive interviews and editorial, as well as producing weekly playlists with a particular genre or theme. 

Up until now, the playlists we have created have only been available on TIDAL and Qobuz, and haven’t been accessible in Roon. In our latest release, you can now access everything our music team has curated, directly from your Home screen on both streaming platforms.

Smarter search

Back in the summer, we released the first of many updates to improve how you search for music in Roon. In this update we’ve taken the next step and completely overhauled the search function to make it easier than ever to find the music you’re looking for.

Now, when you search for music in Roon you’ll see more accurate and concise results (with fewer inaccuracies!), especially when it comes to your library content. Roon will be able to detect when you’re searching for classical music, presenting composers and compositions first. We’ve also overhauled text filtering across the app, for more consistent handling of special characters and punctuation.

The updates we’ve made to search this year are just the beginning. Search has been a top priority for us this year, and led by our data team, it will continue to be a focus into 2022 and beyond.

Rock-solid streaming

We’ve completely overhauled Roon’s buffering and caching infrastructure for playing streaming content. The new implementation is designed to be less demanding when interacting with your network and internet connection, making streaming music both more stable and less intensive on your Roon Core. This should minimize playback interruptions from TIDAL and Qobuz, as well as making it possible for people with slower internet connections and networks to have a better and more reliable experience while using Roon. It will also ensure your Roon Core is more resilient to latency issues caused by Content Delivery Networks (CDN) and the geographic distance from your source.

Easier volume limits

We’ve redesigned the Zone Settings screen so it’s even easier to set volume limits that prevent your music from getting too loud. The new design also makes it easier to configure auto-sleep functionality and other settings for your audio devices.

Other new improvements in this release include: improved iOS lockscreen control implementation, new cover art on playlist screens on mobile devices and added the album type to artist’s “Recommended albums” for easier browsing of main albums, singles, and EPs. You can see a complete list of improvements over on our Community post.

We want to thank our subscribers for everything you have done to help us improve Roon and grow our amazing community this year – we couldn’t have done it without you!

We hope you enjoy the new update and if you have any questions or need some support , you can reach out to our dedicated Customer Success & Support team via our Help Center or head over to our Community and join in the discussions with thousands of other Roon subscribers.
