If your question is how to subset the file, see
https://wiki.gnuradio.org/index.php/File_Source
Offset and Length parameters. If your question is how to use a GUI slider to accomplish this, I’ll defer to others. --- Jim Melton From: discuss-gnuradio-bounces+jim.melton=sncorp.com@gnu.org <discuss-gnuradio-bounces+jim.melton=sncorp.com@gnu.org>
On Behalf Of Giovanni Parodi Good morning, I'm a gnuradio beginner, and I'm trying to better understand some topics related to source and sink. I implemented a very easy SW that allows me selecting a file from filesystem and then I provide the filename to the C++ source implementation, by calling the function: blocks::wavfile_source::make The implementation works fine, but I have an issue. Since sometimes I need to perform audio analysis on files that are quite long, I would like to have a way to use something like a timeslider to move on a specific time instant on the wav file, or at least to change
playing speed of file. I found no property (looking both in C++ and Python generated code) to achieve this target. Is there any way to perform this operation? Best regards
