There is disclosed an audio recorder that automatically determines, when preset microphones are configured to be detachable and different microphones are attached to the same jacks, whether or not the different microphones are in-house microphones, and automatically determines which of the X-Y technique or the A-B technique is used as the attachment technique. Holders in the audio recorder include a switch structure in which, in cases where the different microphones are attached in place of the preset microphones, a contact is turned on only when the different microphones are in-house microphones. Further, a main body unit includes a processor that, when the contact in the switch structure is turned on, automatically determines which of the X-Y technique or the A-B technique is used based on a voltage value of a certain terminal in a plug of the different microphones.

Audio recorder

An audio device is provided which distributes via the Internet a telephone talk between a distributer and a viewer, with a simple structure. An audio interface device can be connected to a PC, and distributes via the Internet a sound signal which is input from a microphone along with a BGM by outputting the sound signal to the PC. When a call is made with a caller, the audio interface device branches the sound signal which is input from the microphone into a first sound signal and a second sound signal, and supplies the second sound signal to the caller. Also, the first sound signal, the sound signal from the caller, and the BGM are synthesized and output to the PC, and the telephone talk is distributed via the Internet.
