3D MP3 Sound Recorder G2 allows you to record the real-time audio stream from the sound card (microphone, line in, and stereo mix) and save it as an MP3, WAV, or WMA file. Among the basic options you can set are: bit rate (8 or 16 bits), sample rate (from 8 to 48 KHz), number of channels to record (stereo or mono), and volume level.
You can also use advanced features, like playback a background music file while recording, use noise reduction, track splitter, and schedule recording. The background music file (mp3, wav, or wma) can be scaled thus setting the priority either for the background music or the recorded audio. You can select the channels in which the background file and the recording will be played, you can repeat the recording when the background file finishes, stop recording, or only stop the background music but continue recording. With this feature you can also remove the human voice from the background music for one or both channels.
The track splitter feature allows you to detect silence in the sound source in order to create a different file every time silence is detected; you can set the threshold and the delay time from 0 to 20 seconds.
