Convert AudioData stream to arrays of floats, and convert arrays of floats to AudioData #84

…rrays of samples.

…rrectly so the callback gets triggered repeatedly with the same buffer. It seems like I need something else in the pipeline to receive the app_buffer.

… I have to know that and cast the data appropriately, or can I force conversion to expected format?

…s in it results in internal data error. Also trying to make noise sound more like online examples- I think when sample rate exceeds output sample rate there needs to be averaging. Also it is possible the mp3 compression is making the sound much different (could increase bitrate?), which is why I want wave to work.

…udio_from_float to have the same prefix as the rest of the projects? Also deleted a lot of commented out code. Inability to kill float_to_audio easily remains, also other major issue is that audio_to_float assumes format to convert to float, I think I understand gstreamer enough to make it do the floating point conversion.

…h float_to_audio, but when I run it manually it does work: rosrun float_to_audio float_to_audio audio:=audio2 samples:=decoded __name:=float_to_audio __ns:=/audio
