Questions on audio recording
Supported audio hardware
Question: What audio hardware is supported?
Answer: In principle, any Windows-compatible sound card is supported for recording. Higher quality sound cards obviously give better recording quality. The microphone used is also very important for the quality of the recording. Please also note our hardware recommendations.
Recommended audio settings
Question: What audio settings are recommended?
Answer: For the best possible sound, we recommend an audio recording with 16 bit sample size (default) and a sample rate of 16 kHz or 22.050 kHz
(default, see figure below).
Recording format
Question: In what format does LECTURNITY record audio?
Answer: LECTURNITY records audio in the special "LECTURNITY audio document" format.
Noise in the recording
Question: There is noise in my recording. What can I do to prevent this?
Answer: Check the following settings:
- Is the sample size set to 8 bits? If the sample width is set to 8 bits, this can cause very loud noise and "cracking" during the audio recording, even if high-quality hardware is used. In general an audio recording with 16 bits is always recommended.
- Is the recording level too low? If the audio signal is too weak, the playback may be noisy because the sound has to be amplified during playback. Therefore, it is important to set the sound level correctly during recording. To this end, the LECTURNITY Assistant has an audio control display (see figure 1) which displays the current recording level. Note the recording level before starting the recording: At normal presentation volume, it should hit just below the red mark. If the recording level is continuously well below this mark, you should increase the recording volume (see figure 2).
- Figure 1: Display of the audio recording level
- Is the recording level too high? If the recording level is too high, the sound may be too noisy or distorted, especially when the speaker's voice becomes a little louder. Before the starting the recording, always check the recording level (see diagram). If this is already reaching the red area at normal volume, please reduce the recording volume (see figure 2).
- Please also see the Live recording instructions on this subject.
- Figure 2: Project settings: "Audio" tab. The volume control for the recording is marked.
Audio device error message
Question: Why do I get the error message "Error when initialising the audio hardware" when calling up the LECTURNITY Assistant?
Explanation: The following error message is always displayed when the audio interface has already been opened for a recording. This is the case, for example, if a LECTURNITY Assistant is already open. After the error message appears, you can work with the Assistant as usual, but you cannot make a recording.
Solution: If you want to make a recording, you must first close all programmes that access the audio interface (including all open LECTURNITY Assistant applications). Then reopen the LECTURNITY Assistant. The error message should not appear again.
