Track Splitter™ technology

Audio Playback Recorder (3D MP3 Sound Recorder ) implements the standard features of many available sound recorders but incorporates one extremely useful feature that sets it apart: its Track Splitter™ technology allows you to record audio streams from CD or Internet Radio that are split into separate WAV/MP3/WMA files automatically. This means that you don't have to baby-sit the process as other audio recorders demand. Nor do you have to convert CD music files from CDA to WAV/MP3/WMA one track at a time.

Tracks are separated by silence. 3D MP3 Sound Recorder can detect silence in the sound source automatically and save each track to different files. With this method, you can set the length of silence for splitting, This enables you to make decision on what kind of silence can split tracks. If you don't want split tracks, you can also use this method to eliminate silence in the sound files, this is much useful when your audio stops for buffering or if there is net congestion.

Track Splitter™ Configuration

According to your setting, the Audio Playback Recorder will pause, stop recording or create new files when signal changes.. Click the signal setup button , you will see the signal setup window. You can set signal threshold and action types. The possible action types can be:

Pause

Only one sound file will be created. The recorder will pause when sound signal goes out and continue to record when sound signal comes back. You need to click stop button to stop recording.

Stop

Only one sound file will be created. The recorder will stop recording when sound signal goes out.

New File

Multiple files will be created. Every time sound signal goes out and comes back again, a new file will be created. You need to click stop button to stop recording.

Delay---- Select a number from 0 to 25 seconds for the period of silence that must pass before a new file is created. This feature prevents a new file from being created when there is a short period of silence within a certain music or speech track.

Threshold -- in dB scale. If signal level high than the threshold, it's a sound signal. otherwise, it will be treated as silence. As mention above, the program will do proper process according to your settings.

Tip: How to determine the silence level and set correct threshold
Do not play anything, start signal recording (by press down the Yellow "Start" button ), pay attention to the signal window, take a note on the signal dB level value (this should be the silence level ), then set the threshold a little bit higher than that value. for example:
If the silence value is -30dB, you can set the threshold as -25dB , -20dB etc
