Configuring the Voice Recorder

Only Voice Recorders with a stereo microphone input will work with RECAP. Check your voice recorder’s user manual to ensure it records in stereo. Note that some models can be configured between monaural and stereo modes, so make sure you have it configured as a stereo microphone before using it with RECAP.

Advantage of Stereo Recording

It’s handy that RECAP grabs the audio of a phone call in stereo. The left channel captures the sound you hear in the speakers, that is the audio coming from the party being interviewed. In the right channel it records your voice, picked up by your headset’s microphone.


Having separate channels for each party facilitate the audio post processing. It’s very convenient to have separate channels for your voice and the other party’s voice, because after recording takes place one would typically perform some audio processing to remove background noise picked up during the call and / or to amplify the speaker’s voice.


RECAP is a simple and useful tool for mobile journalists, reporters, lawyers, consultants and other professionals who wish to record interviews, client calls into their digital voice recorders.
