Terms of Service & Usage Conditions
Last updated: 11 November 2026
Operational Overview
Access to and use of Deckmatics constitutes acceptance of these terms. This application is free to use and is designed to assist DJs, audio engineers, and producers in verifying audio fidelity prior to live performance. It is not open-source software: the source is not published and no licence is granted over it.
1. Original files, exports and write permissions
Deckmatics processes audio locally and distinguishes analysis from write operations:
- The analyzer reads your original audio files without modifying them.
- Library or USB management features can create or update database files when you grant the browser write permission. Analysis and conversion do not overwrite your original audio files.
- All export, conversion, or processing features (including stem separation, format conversion, trimming, and editing) generate completely new and independent files in browser memory, downloadable by the user, without ever modifying, overwriting, or mutating the original source files.
- All diagnostic summaries, LUFS computations, and spectrograms render in temporary browser memory.
2. Technical Disclaimer & Inference Nuance
Audio diagnostics (spectral low-pass cutoffs, transcode detection, True Peak calculation, dynamic range, and EBU R128 metrics) are generated through real-time mathematical algorithms:
- These diagnostics serve as technical guidance for DJs and engineers prior to club playback or mastering.
- Specific music genres (Lo-Fi, vintage hip-hop, vinyl rips, field recordings) possess intentional acoustic roll-offs that do not constitute counterfeit files.
- The user remains ultimately responsible for artistic choices, playback leveling, and acoustic calibration during live sets.
3. Intellectual Property
Deckmatics does not publish the platform source code and does not distribute a licence for it. This page previously stated that the source was released under the MIT License and that anyone was free to inspect, audit and integrate it. That was not true — there is no public repository and no licence file — so the claim has been withdrawn rather than left standing.
All scanned musical recordings and phonograms remain the exclusive property of their respective creators and copyright owners. Deckmatics claims zero rights over scanned audio.
4. System Availability & Browser Compatibility
The software relies on modern web standards (Web Audio API, WebAssembly, and Canvas 2D):
Optimal performance requires standards-compliant browsers. Legacy browsers lacking W3C Web Audio API support are unsupported.
5. Governing Law & Jurisdiction
These terms are governed by applicable Spanish and European Union regulations. Any dispute shall be submitted to the competent courts.
6. General Information & Identification (Art. 10 LSSI-CE)
