Modo por lotes

for f in *.flac; do
  DpdoEngine -i "$f" "${f%.flac}.dsf" --oversampling 128 --order 7
done

find /music/pcm -name "*.flac" | while read f; do
  outdir="/music/dsd${f#/music/pcm}"
  mkdir -p "$(dirname "$outdir")"
  DpdoEngine -i "$f" "${outdir%.flac}.dsf" --oversampling 128 --order 7
done

Paralelo

find . -name "*.flac" -print0 | xargs -0 -n1 -P4 -I{} sh -c \
  'f="{}"; DpdoEngine -i "$f" "${f%.flac}.dsf" --oversampling 128 --order 7 --opencl'

find . -name "*.flac" | parallel DpdoEngine -i {} {.}.dsf --oversampling 128 --order 7

Modo pipe

cat input.wav | DpdoEngine -i pipe output.dsf --oversampling 64 --pipe
ffmpeg -i source.flac -f wav - | DpdoEngine -i pipe output.dsf --oversampling 128 --pipe

ffmpeg -i track.flac -f wav - | \
  DpdoEngine -i pipe track.dsf --oversampling 128 --order 7 --lufs -16 --pipe

DpdoEngine -i input.flac output.dsf --oversampling 64 --pipe | DpdoPlayer - --vol 80
