Audio Volume Normalization & Re-Encoding
Avoid volume jumps when switching between loud action movies and quiet acoustic tracks. RideStream offers two complementary tools: a real-time Dynamic Audio Normalization setting that levels loudness during playback, and a new batch Normalize Audio Volume feature that re-encodes your files to a permanent, consistent loudness.
Two Ways to Normalize Audio
Dynamic Audio Normalization (Playback Setting)
Enable Dynamic Audio Normalization in Settings ⚙️ to level loudness in real time while you listen. RideStream measures each track's loudness using the EBU R128 loudness standard (LUFS) and ReplayGain-style gain adjustments, then applies balanced gain so every song and movie plays at a consistent volume.
- Prevents clipping: digital peaks are kept under control so loud tracks don't distort.
- Zero file changes: your original files are never modified.
- Best for: everyday listening where you simply want consistent volume between tracks.
Normalize Audio Volume (Batch Re-Encode)
The Normalize Audio Volume action re-encodes audio (and video) tracks in a playlist to a permanent, consistent loudness using an FFmpeg-based EBU R128 loudness filter. It's designed for exactly the cases where the dynamic setting isn't enough: you get files that sound level on any device, app, or stereo.
-
Open the playlist you want to normalize.
Any mixed playlist containing audio and/or video files works. Supported formats: MP3, WAV, FLAC, OGG/Opus, M4A/AAC, and video (MP4, MKV, AVI, and more).
-
Tap the volume icon / Normalize Audio Volume.
From the playlist screen, tap the normalization button to open the dialog.
-
Choose a target loudness level (LUFS).
STANDARD (RECOMMENDED) 🎯 -16 LUFSMUSIC 🎧 -14 LUFSCINEMA / SOFT 🎬 -18 LUFS
- Standard (-16 LUFS): balanced default, ideal for mixed audio & video playlists.
- Music (-14 LUFS): slightly louder output, tuned for music tracks.
- Cinema (-18 LUFS): preserves a wider dynamic range, tuned for film soundtracks.
-
Pick a destination and start.
You can write the normalized files into a new playlist (a copy — your originals are preserved), or replace the current files in place (the normalized versions replace the originals).
-
Done — level, everywhere.
RideStream re-encodes each track with the EBU R128 loudness filter (including true-peak limiting), so the result plays at a consistent volume in RideStream and in any other player.
Which One Should I Use?
In short: use Dynamic Audio Normalization for effortless daily listening, and use Normalize Audio Volume when you need the loudness baked into the files themselves — like for Bluetooth car audio or sharing media with other apps.
