Bug#896190: Acknowledgement (ffmpeg convertion from dsf to flac - noisy at the end of file)

[Serge Pouliquen]

Hi

In case of interest, I attached an audacity capture.

ffmpeg output convertion was:

ffmpeg output is :

ffmpeg -i "2L-125_stereo-11289k-1b_04.dsf" -acodec flac -ar 96000 
"2L-125_stereo-11289k-1b_04.flac"
