Resomix is a music discovery platform that helps you find tracks based on how they sound — not by genre, popularity, or metadata.
Powered by our proprietary PYXIS-1 engine, Resomix analyses over 70 distinct audio characteristics of each track, including:
Rhythm patterns
Harmonic content
Spectral energy
Timbre
Dynamics
Structural composition
The result is a discovery experience built around genuine sonic similarity, helping you find tracks that share the same mood, feel, and musical character.
PYXIS-1 creates a unique sonic profile for every track by extracting and analysing more than 70 measurable audio features.
When you select a reference track or upload your own audio file, the engine compares that sonic profile against the full catalogue and returns the closest sonic matches.
This is deterministic analysis: the same input always produces the same results. That gives you a reliable and consistent way to discover music that matches the sound, mood, and feel of any track you provide.
PYXIS-1 is a deterministic computational algorithm.
It is:
Not artificial intelligence
Not machine learning
Not based on neural networks
Not trained on user data
Not adapted through user interactions
Not generating probabilistic outputs
Instead, PYXIS-1 applies mathematical transformations to extract measurable audio characteristics and calculate similarity scores through algorithmic comparison.
All results are reproducible and consistent for identical inputs.
This architecture falls outside the definition of an “AI system” under Article 3(1) of Regulation (EU) 2024/1689, the EU AI Act.
Resomix is designed for DJs, producers, music supervisors, and curators who prioritise sound over trends.
It is especially useful if you want to:
Find tracks that blend well together
Discover music beyond genres and charts
Build more coherent playlists or DJ sets
Explore hidden gems based on sonic similarity
Match tracks by mood, energy, rhythm, and feel
Most music platforms recommend tracks based on popularity, user behaviour, or genre tags.
Resomix focuses on the sound itself.
Our PYXIS-1 engine examines over 70 sonic characteristics, including timbre, dynamics, energy, rhythm, harmonic content, and structural composition, to identify tracks that genuinely sound alike.
Because PYXIS-1 is a deterministic algorithm — not AI or machine learning — results are consistent, transparent, and reproducible.
This helps you discover hidden gems and explore musical connections based on how music sounds, not how it is categorised.

Full, current details are available on the Pricing page, which forms part of the Terms of Service.
Paid plans renew automatically at the end of each billing period — monthly or annual — until cancelled.
Before payment, the total price is displayed clearly, including any applicable VAT.
Payments are processed by Stripe. Resomix does not store full card details.
If a renewal payment fails, we may retry the payment and notify you. Paid features may be suspended until payment succeeds, and your data and analysis history are retained according to the Privacy Policy during suspension.

You can cancel at any time from:
Settings → Subscription
This is the same place where you subscribed.
No email, no support ticket, and no phone call are required.
Cancellation takes effect at the end of your current billing period, and you keep access until then.
If you are an EU consumer, you have a statutory right to withdraw within 14 days of your first purchase, unless you consented at checkout to immediate access and acknowledged losing that right once the service begins.
If the service materially failed during a billing period — for example, due to a verified outage or defect — contact [email protected] within 30 days. We may refund or credit you at our discretion.
Renewal charges for a period that has not yet started are refundable if you requested cancellation before the renewal date but the cancellation was not processed due to our error.
Full details are available in our Refund Policy. Nothing in the Refund Policy limits your statutory consumer rights under EU or Greek law.
If we change our prices, we will give you at least 30 days’ notice by email.
Any price change will only apply from your next renewal.
If you do not accept the change, you can cancel before it takes effect.
Yes. Each plan includes quotas, such as uploads per month, to help keep the service fast and reliable for everyone.
The following are not allowed under the Terms of Service and Acceptable Use Policy:
Automated bulk submission through the consumer interface
Sharing API keys
Circumventing quotas
Attempting to bypass plan limits
If you need higher volumes, API plans are designed for that use case.
Resomix is primarily a discovery platform, not a traditional streaming service.
You can play tracks to evaluate sonic matches via Apple Music playback, but the core purpose of Resomix is to help you discover music based on how it sounds — not to provide a library for casual listening.
Depending on your plan, Resomix allows you to:
Discover sonic matches generated by the PYXIS-1 recommendation engine
Play catalogue tracks via Apple Music
Upload your own audio files for similarity analysis
Create, manage, and export playlists
Export playlists on Premium
View the full feature report on Premium
Access the structure view on Premium
Use the analysis engine programmatically through API plans
Integration with external DJ software is planned for future releases.
Features may change as the platform develops. Material reductions to a paid plan will not apply to an active billing period.
Yes.
Resomix can help you explore tracks linked by sound, making it easier to build more coherent and original DJ sets.
You can use the playlist features to organise discoveries and develop new musical directions for your performances.
While integration with external DJ software is planned for future releases, Resomix can already help inspire new transitions, combinations, and creative set ideas.
Resomix works on all modern desktop and mobile browsers, including:
Chrome
Firefox
Edge
Safari
Yes. You can upload audio files for similarity analysis.
By uploading audio, you confirm that you own or control the rights to the audio, or that you are authorised to submit it for analysis.
Uploaded audio is processed ephemerally:
The full source file is deleted immediately after feature extraction
A 30-second verification fragment is purged within 24 hours or when your session ends

PYXIS-1 does not train on any content — yours or anyone else’s.
It performs deterministic feature extraction and similarity analysis only.
Your uploaded audio is processed temporarily to generate a sonic profile for matching purposes, and the source file is not retained.
PYXIS-1 does not adapt, learn, or modify its behaviour based on user content or interactions.
