ffmpeg wma to wav

Question

我已经用ffmpeg尝试了各种参数来使这个工作,但它们都导致了一个staticy音频文件.

我试过的一些是:

ffmpeg -i file.wma file.wav
ffmpeg -sameq -i file.wma file.wav
ffmpeg -i file.wma -ar 44100 -ac 1 -ab 64000 file.wav
ffmpeg -i file.wma -vn 64000 file.wav

这是音频文件的链接:(删除了断开的链接)

Answer 1

它正在ffmpeg -i Untitled.wma Untitled.wav为我使用,使用来自Ubuntu存储库的ffmpeg.

版本输出:
