Reads raw data values in binary format from the specified file. This file can be a file that was captured using a File Sink block, generated with a computer program or saved from an audio editor such as Audacity (using suitable RAW format options).
Parameters
(R): Run-time adjustable
- File (R)
- Filename of binary file. Note: The file MUST be on the local computer.
- Output Type
- Because a binary file does not store information about what type of data is in it, we have to tell GNU Radio the format.
- Repeat (R)
- Whether or not to repeat the signal, once the end of the file is reached
- Add Begin Tag (R)
- Tag to add to the first sample of the stream.
- Offset
- Begin this many samples/items into file
- Length
- Produce only this number of items (offset, offset+len)
