[Mpg123-users] Decoding small clip of mpeg audio

[Nicholas J H. <nj...@ec...>]

Hello,

Has anyone tried using mpg123 to decode small sections of a large MP3  
to Wave file?

I have some MPEG Audio files, that I want to extract 30 second clips  
from. It would be nice if I could give mpg123 the time ranges that I  
want to extract. I guess with CBR files, I could do it using frame  
counting, but it would be nice to just pass the times directly to  
mpg123.

At the moment I am decoding the whole file, and then using sox to  
extract the chunk of audio I want.

Before I start looking at hacking support into mpg123, has anyone  
attempted anything like this before?

        -k num, --skip num
               Skip first num frames.  By default the decoding starts  
at the first frame.

        -n num, --frames num
               Decode only num frames.  By default the complete stream  
is decoded.
