Convert

It might be useful to convert when finishing a dictation for later processing or if transcription is done within another software like VLC Player or foobar2000 or any other with ffmpeg support.

Automatic conversion
Open General Settings and go to Dictation, select Automatic conversion
Here you can define the audio format of dictation files which were not created in SpeechExec and which have a format that only supports playback (.wma, MP3, etc.). To open a dictation and continue recording in these files they must be converted to a SpeechExec format which supports recording.
You can also convert dictations when you have finished recording. This is useful if you need a specific format to process the dictation within another program. For example, if you are using a speech recognition system.
The following options are available:
Convert automatically when opening a dictation
Activate this option to automatically convert the dictation file to the configured audio format (.wav, .dss or .ds2) when the dictation is opened.
