Insert audio into the middle of a file

[Philipp Wagner]

Hi,

I'm developing a software which needs to insert (recorded) audio in the 
middle of a Speex-encoded file in the default OGG container. How could I 
do that? I know that with filesink I can append to a file, but is there 
some way not to append but to insert and/or overwrite at a certain time 
(e.g. at the current playback position, record and insert new audio). 
The whole thing is going to be a dictation software, that's why this 
feature is needed.

Any pointers how that could be done?
