Musikdateien von AAC to MP3 konvertieren

Hallo,

ich möchte AAC-Dateien nach MP3 konvertieren, weil mein MP3-Player kein AAC kann.

Dabei kommt es zu Fehlermeldungen, die ich nicht nachvollziehen kann:

faac, faad2, lame sind installiert.

Dateinamen werden im neuen Verzeichnis angelegt, und mit (vermutlich)
den Headerdaten gefüttert.
Abhängikeiten von der Installation her kann ich nicht erkennen. Aber das sollte nichts heißen.

Das sieht so aus, als würdest du 'lame' direkt auf das aac File loslassen. Das kann meines Wissens nach nicht funktionieren.

Ansonsten finde ich Deine Angaben sehr ungenau.

gestartet mit mit Hilfe von Audiokonverter 5.8. Davor hatte ich den Audiokonverter 5.7.1 benutzt
 

whois

Sonst probier doch mal zum testen den Mediaconverter hier aus.
Damit hast du zumindest ein Ausschlussverfahren.

So habe jetzt Ergebnis von soundKonverter:
sieht genauso besch... / schlecht aus.
Es muß an faad liegen bzw den übergebenen Params , denn auch hier kommt die Fehlermeldung Error: Bitstream value not allowed by specification

Die Befehle
Code:
mplayer file.aac -ao pcm:file=out.wav
lame -h out.wav out.mp3
führten dann zum Erfolg.
Allerdings auch nicht ohne Fehlermeldungen. Vieleicht kann der geneigte Fachmann mehr aus den nachstehenden Zeilen erkennen :
