Flacgain [Ad-Free]

where ( i ) is the frame index containing sample ( n ). Crucially, the player applies a 10ms linear crossfade between ( g[i] ) and ( g[i+1] ) to avoid discontinuities.

We invite implementation in ffmpeg, sox, and open-source players. A reference Python library and a set of 50 test samples (classical, jazz, electronic, field recordings) are available at https://github.com/example/flacgain . flacgain
