This is regrettably not the case, as many wireless audio devices incorporate hardware compression, reducing the quantity and quality if the information sent. They also often employ noise gates and may even employ level compressors to account for the more limited dynamic range of many wireless transducers. 

If in doubt, a simple measurement can be performed to test if this is the case with a given setup, and I highly encourage you to do this before any experiment using such equipment.

Hi!! Since my poor knwodlege just I can say you that there are not degradiation at all.  when you are using a wireless comunication you dont change the packets of the signal!! So, you receive exactly the same that you send.

Go a head, man!

Asunto: Wireless Audio for Research

Hi All,

I was wondering if anyone had thoughts about wireless audio connections
for research.  We are running our spectral resolution task (SMRT;
smrt.tigerspeech.com) on a small windows 8.1 tablet.  It would be nice
for the audio to be transferred wireless to the speakers.  I am
considered about degrading the signal quality.

Any suggestions on how to do this without adding signal noise or lossy
data compression?  I understand bluetooth is not acceptable.  What
about  using airplay, miracast, or chromecast?  Has anyone had luck /
experience with these technologies for wireless PC audio streaming of
quality acceptable for psychoacoustic research?

Thanks,
David
