Re: Sound recording

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]



Thanks for everyone's response.

I eventually got it working by switching from OSS to ALSA (which, it
sounds like is the better sound system) and ensuring the Capture line
wasn't muted.

This brings me to my new problem.  When I record from TV, everyone's voice
seems too high pitch and there is a high pitch 'ringing' sound in the
background.  I am using the standard cable that goes from the output of
the TV card to the line-in on my sound card.  I am using mencoder and here
is what I issue:

mencoder -tv
on:driver=v4l:input=0:width=320:height=240:fps=29.97:norm=ntsc:alsa \
-ovc lavc -lavcopts vcodec=mpeg4 \
-oac mp3lame -lameopts cbr:br=96 \
-vop pp=lb -o mp_out.avi < /dev/null

It almost seems to me that the TV Card is outputting too low a volume.  I
tried using v4lctl volume 60000 but it seems to have no effect.  Does some
sort of mixer for the TV Card need to be loaded for this command to work??
Increasing the Capture (Input gain) only seems to make it worse.  
 I have tried everything to fix this but nothing improves the situation. 
I did try to record through the btaudio driver instead but I couldn't get
it working.

If anybody has encountered this problem and has a solution I would be
happy to hear it.  Otherwise, I might try the ALSA list.
