Hello Danny and welcome to the Cow Audio Forum.
I get hired to “single-end record” an interview about 4-5 times a year. In that scenario, I go to the person’s home or office, find a nice quiet spot, setup my hard disk recorder boom and mic. The interviewer calls in. I record the interviewee’s half of the conversation and forward it by sending the .wav or mp3 file to a server where it can be downloaded.
NPR does this a lot. That way, you have a pretty near studio quality recording (ambience dependent) and it sounds quite nice.
Any use of regular telephone lines subject you to the vagaries of the line itself and the individual telephones used. I do know of a radio station that used a speakerphone and an electrovoice 635a mic to put their callers on the air, but it never sounded very good.
SKYPE sound pretty good these days when I’ve tried it, but not as good as my first example and, again, the quality is very subject to the hardware.
The question is, how good do you want it to sound?
Regards,
Ty Ford
