When you record streaming audio, or digitize recordings from cassette you get a large audio file that will contain all the songs. Of course, this is awkward. The audio recorder allows you to split the file in two ways - automatically during recording or manually when a record has been completed.
To separate tracks during recording, you can use the sound activated recording mode. This mode will detect pauses between songs and every time create a new audio file. It is important to choose a threshold value and delay so that the recorder did not split the song in half by mistake. These values will depend on the parameters of the audio stream. The very idea of separation by pauses has one drawback - some radio stations broadcast music without pauses between tracks. However, this method works fine on cassette and vinyl.
The surest way to split the file into separate tracks - use audio editor. If you don't have it, you can install a free sound editor directly from i-Sound. You can select an individual track in waveform display or set range while listening. If you know the exact time of the track, you can specify the start and end of the track in the editor by hand. After that you can just call the context menu and select "Save selected as ..."
In the case of sound editor is better to choose the WAV output format. File size will be large, but you can avoid any loss of quality during recompression.
