It reads audio stream from a Microsoft PCM (pulse code modulated) (.wav) file (all versions of GNU Radio) and every other file format that libsndfile supports (GNU Radio 3.9.0.0 and later).
Its output is a float stream.
Unless called otherwise, the values are inside the range of [-1:1].
Parameters
(R): Run-time adjustable
- File
- Path to the .wav file to be read
- Repeat
- Repeat playback of the file when end is reached
- N Channels
- Number of audio channels to output
Example Flowgraph
This flowgraph shows a Wav File Source block producing pre-recorded radioteletype signals.
