About this plugin
The Studio Player – Sync by Design
The Studio Player is a professional WordPress audio player for mixing and mastering portfolios, before/after demos, recording studio portfolios, producer portfolios, composer portfolios, and other serios audio presentations. It lets visitors compare synchronized audio versions with sample-accurate switching, lossless FLAC streaming, waveform support, and shortcode-based embedding.
Unlike generic MP3 players built mainly for consumer playback, The Studio Player is designed for professional portfolio use. It helps audio professionals present their work in a way that makes sonic differences immediately audible while keeping playback locked in sync. Switching between tracks feels just like pressing the solo buttons in the studio.
This makes it especially useful for portfolio websites where sound quality, comparison accuracy, and a professional presentation matter.
The plugin includes an integrated Muxer-Uploader in the WordPress admin. Drag and drop your stereo WAV files, and the plugin encodes and combines them into a single efficient multichannel lossless FLAC streaming file. This reduces server requests, ensures 100% sync accuracy, and creates a workflow that fits real studio portfolio publishing.
The audio content is streamed and protected from direct download by time-limited tokens.
The Studio Player is not just another WordPress music player. It is a portfolio player built for professional audio comparison, lossless presentation, and WordPress-based portfolio workflows.

Free and Pro
The free version of The Studio Player includes the full player, the playlist editor, the FLAC muxer/uploader, integrity checks and optional sample content. It works completely on its own and does not expire.
The free plugin core remains fully functional without Freemius license activation or Freemius connect opt-in.
de so you can test the plugin immediately with real data.
A separate Pro add-on unlocks an advanced audio engine and tools like data recovery, waveform JSON generation and waveform rebuild utilities. Those Pro features are implemented in a separate premium-only integration, not as disabled code inside the free plugin.
A dedicated Tools page provides recovery, waveform rebuild and integrity utilities to keep existing Studio Player libraries healthy over time.
Players are built as dedicated “Player-Builder” entries (custom post type), so you can create multiple independent players with their own templates and designs.
Security
The Studio Player secures its admin AJAX endpoints with nonces, strict capability checks and sanitized input (titles, filenames, subdirectories, JSON payloads) before storing anything.
The playlist REST API follows WordPress visibility rules (published playlists are public, drafts/private playlists only for users who can edit them) and restricts audio attachments to FLAC/WAV via extension and MIME allowlists.
The streaming engine uses signed, time-limited URLs, directory protection, safe path checks and IP-based rate limiting, and loads player templates only from sanitized slugs in fixed directories with a guarded fallback so broken templates show a safe error UI instead of causing a fatal error.
Remote Content & Privacy
de – onboarding, banners, documentation and the changelog – in your WordPress admin area only.
Remote content loading is strictly opt-in and can be turned off at any time in the plugin settings. No tracking pixels or analytics scripts are injected, no listening or playback data from your visitors is sent to us, and all remote responses are cleaned down to basic, safe HTML before being displayed.

The sample import is started manually by an administrator, stores the downloaded files temporarily in the WordPress uploads directory, and does not transmit visitor playback data to our server.
