Terms of service
Last updated: May 1, 2026
The Slerp demo (slerp.audio) is provided “as is” for personal evaluation and creative use. It is not warranted to be fit for any particular purpose. You are responsible for any audio or other content you load in your browser and for compliance with the rights of others.
Local-only processing. Audio playback, frequency analysis, and the optional Studio reactivity feature all run inside your browser on your own device. The Studio reactivity analysis (stem separation, beat detection, energy and vocal envelopes) runs entirely on your device’s graphics processor through the browser’s WebGPU API. We do not operate any server-side inference path, and audio you load is not uploaded to us. See the Privacy policy for full details.
Loud audio, reactive visuals & on-device compute
The demo plays audio through your speakers or headphones, renders bright, music-reactive visuals, and (when you opt in to Studio reactivity) runs an audio analysis model on your device’s graphics processor. Three safety notes:
Audio. The deck applies a digital output ceiling, but the loudness you actually hear depends on your operating-system volume, your headphone or speaker amplifier, and the loudness of the file you load. Start with the volume low and raise gradually. If you experience discomfort, lower the volume or stop playback. You are responsible for your playback level and use audio features at your own risk.
Photosensitive epilepsy. The reactive backdrop pulses, flashes, and rotates with the music. A small percentage of viewers may experience seizures or other adverse reactions when exposed to certain visual patterns, including flashing lights or graphics. If you have photosensitive epilepsy or any history of seizures triggered by light, set the Scene picker to “Off” (that tears down the backdrop), or do not use the demo. A first-visit splash warns you before the deck is interactive; the demo loads a bundled starfield backdrop by default so the visualizer is obvious, and you can turn it off in Scene at any time. By using the demo you acknowledge these risks and agree that you use the demo, including audio and visuals, at your own risk.
On-device compute & device performance. Studio reactivity (opt-in; you tap the STUDIO button) runs an audio analysis model — stem separation, beat detection, and similar — locally on your device’s graphics processor through the browser’s WebGPU API. While the read is in progress your device may use meaningful GPU and memory resources, draw battery, and run warmer than during ordinary playback. The deck performs a one-time download of the analysis model bundle (roughly 50 MB) on the first read and verifies its integrity before running it. If your browser or device cannot run on-device inference, the Studio feature is disabled and the deck falls back to live frequency-based reactivity. You are responsible for whether your device is appropriate for this workload (battery state, thermal headroom, mobile data use for the initial model download), and you can stop the read at any time by tapping STUDIO again.
To the maximum extent permitted by law, the demo is provided without warranty of any kind, and the operator is not liable for any indirect, incidental, special, consequential, or punitive damages arising from your use of the demo — including, without limitation, hearing damage, photosensitive seizures, device performance issues, battery drain, or loss of data.
We may change or discontinue the demo or these terms; continued use after changes are posted means you accept the updated terms.
