Frequently asked questions

Will Spotify always turn a quiet track up?

Playback normalization depends on platform and user settings. A quiet master is not always raised fully to the nominal target.

Is mode C actually encoded?

Yes. Mode C plays a real AAC or MP3 file created with FFmpeg.

Why can true peak rise after encoding?

Lossy reconstruction can create new inter-sample peaks.
