Audio analysis- slow. When I select a new song to play or click next, it takes few seconds (5-10 seconds) before music starts to play. I checked off fastest setting for audio analysis. I believe this was much faster 6-12 months ago. Any way I can have faster playing or turn OFF the analysis? I don’t have any DSP on. Just pure streaming.
(Curious - does Roon analyze music every time it plays a song? If no, does it analyze fresh when I switch audio device? Can I have all music analyzed so Room does not have analyze again?)
Describe your network setup
Synology DS1019+ with Intel Celeron J3455 quad-core processor with Room server, Orbi gigabit wired network, multiple audio devices - Krell K300i, Sonos, Bowers&Wilkins Wedge, Hifi Rose Rose 150B, Lumin T2. I have my library - 2TB, Qobuz, TIDAL.
Based on your setup, your Synology DS1019+ with an Intel Celeron J3455 is likely the limiting factor. This processor is relatively low-powered by today’s standards and can struggle with real-time operations like on-the-fly audio analysis, especially with larger libraries and multiple zones.
A few clarifications:
Roon does not analyze music every time it plays a track — if analysis was already completed and stored, playback should begin quickly.
However, if you recently added new tracks or changed storage paths, some files may be re-analyzed. .
Audio analysis is also required to provide waveform, dynamic range data, and volume leveling, and may affect how fast metadata like lyrics or cover art appears.
We do not perform the analyze again if you switch audio device
Additionally, extensive background analysis is ongoing to keep the library up to date
To improve performance:
You can disable or slow down audio analysis under Settings > Library > Background Audio Analysis Speed. Disabling it may improve playback speed but may prevent Roon from fetching some metadata for unprocessed tracks.
If you choose “Fastest” but your CPU is underpowered, you’ll still notice delays.
Troubleshooting suggestion:
To determine if the issue is due to the processor or the network, we suggest temporarily moving the Roon Core to a more powerful device (e.g., a desktop or laptop) within the same network, and checking if playback speed improves.
If it does, the issue is very likely CPU-bound rather than network-related.
Let us know if you’d like guidance on setting up Roon temporarily on another device for testing.
