L5 mic picks up the same frequencies with Samsung A50 but the gain (volume of recording) is too low. I would say at least 60% less than A50. Why this?
I will try the following setup that uses 4 phones and a PC.
Ph1=L5
Ph2=A50
Ph3=S8
Ph4= a tablet
PC plays a song with talk clearly above music, to Ph1 mic which is in a call with Ph3.
Ph3 has open its speaker and the sound gets recorded by Ph4.
Same setup but now PC plays the song to the mic of A50 which is in a call with Ph3.
Ph3 has open its speaker and the sound gets recorded by Ph4.
All Ph1, 2 and 3 are on the same cellular company.
Then I will recreate spectrograms.
