All audio files are not recorded with the same volume levels. Recently mastered audio files are recorded at higher volume levels when compared to older audio tracks. When you stream a playlist with a combination of both new and old audio tracks, the inconsistency in the volume levels would be evident.
BluOS provides an option to stabilize the volume using the Replay-gain setting embedded in the digital file encoding of the audio track. This avoids the need to manually adjust volume levels between tracks.
To configure the Replay-gain setting, perform the following steps:
- In the BluOS Controller App, select the Player Drawer. The list of connected Players is listed.
- Select the required player and select the context menu (3 dots).
- Select Audio Settings from the modal window. The Player’s Audio setting screen is displayed.
- Select Replay-gain.
- On the Replay-gain modal window, select any of the following options:
(These modes depend on the volume adjustment metadata tags stored in the audio file to output appropriate volume levels)
- Disabled – Replay-gain is not applied.
- Track gain – Volume adjustments performed on the individual tracks, ensuring all tracks playback with equal volume.
- Album gain – Volume adjustments performed on albums - this maintains dynamic volume differences of tracks in an album.
- Smart gain – Combination of Track gain and Album gain providing the best volume level for each file during playback.
Alternatively, the Replay-gain modal window of the selected Player can be accessed from the left Navigation Drawer, navigating through Settings > Player > Audio > Replay-gain.
