ADPTR Audio Streamliner free download
You’ve finished a master, but you’re not sure how it will actually sound once it’s processed by Spotify or Apple Music. ADPTR Audio Streamliner addresses this by letting you preview your audio through the exact codecs used by streaming platforms before you upload. It’s a free download that gives you a direct listen to what your listeners will hear.
What It Does
This plugin sits on your master bus and lets you audition your audio through the same algorithms used by major streaming and download services. You can switch between codecs instantly to hear the differences. It also includes an integrated A-B switching system to compare your track against a reference, with automatic loudness matching to make comparisons fair.
Key Functionality
Codec Auditioning
You can preview audio through streaming and download codecs from services like Spotify, Tidal, Apple Music, YouTube Music, Deezer, and SoundCloud. The list also covers platforms like Facebook Video, Instagram, and Twitch.
Analysis and Matching Tools
The plugin provides loudness, dynamics, and true peak level metering. The Automatic Loudness Matching feature lets you A/B your track against a reference at the same perceived volume. You can also set target levels.
Workflow and Export
The Reference Track Comparison feature works with the A-B system. You can export tracks at all the bitrates used by each major platform from within the plugin.
Who Should Use It
This is built for mastering engineers and producers who need to check how platform processing will affect a final master. It fits the scenario where you need to hear the impact of loudness normalization before your track lands in a playlist. It’s also useful for previewing tracks for clients across different streaming codec configurations, or when you need to export a single track at multiple service-specific bitrates.
Final Verdict
If your work ends up on streaming platforms, this plugin lets you hear the final step of processing that happens after you export. You get a direct way to find out how much loudness normalization will affect your master in a playlist context and to compare mixes to reference tracks through actual service codecs. It works as a VST, VST3, Audio Unit, or AAX plugin. For a mastering engineer, it’s a straightforward tool to validate a master for streaming, and as a free download, it’s worth adding to your chain for that final check.
