In your set up is it possible to route the audio out of the bluetooth adapter and then from the RTL-SDR into a DAW (digital audio workstation such as Cakewalk, Reaper, Audacity etc etc) as separate tracks, then compare the waveform traces?
Keep in mind that bluetooth has some real drawbacks if you are interested in clean and fast audio.
First up, bluetooth has enormous latency, generally thought to be between 34-200 milliseconds depending on the equipment and the usual RF issues, which can seriously screw with audio performance. Does this latency matter in an SSB audio set up? I have no idea, but in recording and mixing with a DAW it all but makes bluetooth headphones and microphones unusable.
The other thing to consider that using bluetooth means that the audio stream is encoded and decoded by various components along its journey (which is part of the latency issue) so each transformation makes its own changes to the stream.
