Dobrý den,

mám písničku ve formátu mp3. Tu bych chtěl oříznout. Vybral jsem si takový blbý postup, nic lepšího mě nenapadlo (tu písničku mám jako jedinou v playlistu mocp):

1. mocp --sound-driver ALSA --server
2. mocp --play
3. mocp --jump 185s ; arecord --format=cd --file-type wav --duration=66 orez.wav
4. aplay --format=cd --file-type wav orez.wav
5. No a když bych už měl "orez.wav", tak bych ho pomocí lame převedl do mp3.

Jenže ať nastavuju přes alsamixer cokoli, tak ve výsledku je ten ořez neposlouchatelný hnus.

Přikládám též výstup z amixer. Zkoušel jsem nahrávat jak v "čistém příkazovém řádku (žádné DE či WM, resp. žádný X Window System), tak v KDE 4.13.0, kde jsem v kmix dal preferovat ALSu.

Předem děkuju za všechny rady.
