We want to keep Beat Sage free for everyone, but our server costs are high and continue to increase as more and more people use the service. To both keep the service free and reward our loyal supporters, we are offering some features only after we meet certain milestones of Patreon subscribers.
Currently, Patreon subscribers get the following upgrades:
- For Disciples, 2x max level length (up to 20 minutes)
- For Sages, 3x max level length (up to 30 minutes)
- For Gurus, 3x max level length, and immediate access to 360 Levels!
Note that these may change over time. Stay tuned!
To activate these features, follow these three easy steps:
- Join our Discord server
- Link your Discord account to your Patreon
- Activate upgrades via Step 0 above
If you have followed all of these steps and your upgrades are not working, please try clearing your cookies for beatsage.com (instructions). If that does not fix the issue, please reach out by DMing a dev on Discord or directly messaging us on Patreon!
Yes, your Patreon subscription must be active to receive the upgrades.
We would strongly prefer to keep Beat Sage free and open to the public as opposed to charging per song or having subscription fees. However, we are only able to keep Beat Sage freely available if our level of Patreon support meets our server costs. If you like Beat Sage and have the means, please consider supporting us on Patreon.
In order, Patreon support will be used to (1) offset server costs, (2) develop the features promised for our subscriber milestones, (3) improve the overall quality of the Beat Sage AI, and (4) fund design and development of speculative features for Beat Sage. Regarding (4), we have some exciting ideas for where to take Beat Sage in the future. Among these ideas are things like integrating Beat Sage directly into VR headsets, building a leaderboard system, and adding support for other VR rhythm games. If you would like to see any of these features, please consider supporting us on Patreon.
You may upload your favorite Beat Sage maps to BeatSaver and share them with others.
The most common reason a particular YouTube video will not work with Beat Sage is that the video is not available in the US. Another reason is that our server has occasional difficulties communicating with YouTube. As a workaround, please try uploading an MP3!
When we built the new Beat Sage AI, we identified two different strategies for generating levels from the same neural network that produced fun but different results; we named these models "V2" and "V2-Flow". V2 will typically produce far more song events like bombs and obstacles. V2-Flow tends to produce fewer events and seems overall less creative, but it produces arrow block patterns which are typically more readable and work well for songs with fast tempos ("stream"). Feel free to experiment and choose which model fits your personal playstyle!
Beat Sage will now return a different level every time you use it. If you don't like the first map that it produces for your song, feel free to try it again! Note that while the block sequence will change the next time you map the same song, the timing of the blocks will not change.
While we strive for a Beat Sage AI that produces a human-quality level for any song, the reality is that the current version of Beat Sage was trained mostly on electronic music. Hence, Beat Sage will work best for music with a strong beat, and may completely fail on other genres such as rock or vocal-heavy music. We encourage you to try out many songs from different genres, and please give us feedback by slashing the purple block above if you are unsatisfied! Your comments will help us improve our AI.
While it may seem highly unusual, the sparsity of blocks in easier Beat Saber difficulties is actually more difficult for our AI to handle. In the future, we may solve this problem, and in that case we will offer the Easy mode.
We were disappointed to hear reports about this, so we created a verification tool that can actually infer if a song was created with Beat Sage versus a human-made map! You can check it out here: verify.beatsage.com. We hope this can help protect folks from feeling helpless if this happens!
Beat Sage uses two neural networks to map an audio file into a plausible Beat Saber level. These neural networks were trained on Beat Saber levels created by humans. The first neural network listens to the audio and predicts at what points in time blocks should be placed. The second neural network looks at the predicted timings and maps each to a timestamp to a block type (e.g. red up, blue down, red up + blue down). If you want to learn more, you can read the paper for Dance Dance Convolution, an earlier system Chris built which is nearly identical in architecture to Beat Sage.
Beat Sage doesn’t reason about beats the same way humans do and as such does not know the tempo for a given song. The generated level will not be affected by this BPM value.
If a song is not available in the United States, our server will not be able to process it because we cannot access it. As an alternative, you may upload an MP3 of the same song.
By enabling song events (e.g. bombs), you simply gave the Beat Sage AI the option to add these events to the generated level. Beat Sage will sometimes choose to ignore this power and there's little us humans can do to convince it otherwise!
You are absolutely welcome (and encouraged) to share footage of you playing Beat Sage maps anywhere (YouTube, Twitch, etc.) and share on any social channels (Twitter, Instagram, etc.)! If you share on Twitter, tag @BeatSage_AI so we can retweet!
If you have feedback (positive or negative) on an individual song, please give us feedback by slashing the purple block above. If you have general feedback, please let us know by posting in the #feedback channel on our Discord or posting on our subreddit!
Beat Sage was created by two enthusiastic users of Beat Saber, but is not in any way affiliated with Beat Saber (the game), or Beat Games (the company that works on it).
We are thrilled that many of you have expressed interest in building software which uses Beat Sage! We ask that you please contact us first on Discord so that we can make sure the application you have in mind agrees with our overall vision for Beat Sage. Since we aren't yet officially supporting an API, we reserve the right to modify our backend at any time which may break your 3rd-party application.
