Enhanced audio recording settings in iSpring
When you are recording an audio narration for a course, there may sometimes appear an extra background noise, or sound volume may vary. To help you make recordings sound more clear and increase their quality, iSpring tools have been enhanced with advanced audio recording settings. You can fine-tune these settings according to your requirements, which may depend on the narrator's voice or mic parameters.
You can fine-tune audio recording settings for audio narrations in courses, quizzes, interactions, dialog simulations, and screen recordings.
How to customize audio recording settings in advance
To customize audio recording settings in advance, open your course in PowerPoint. Then go to the iSpring tab on the ribbon and click Options.
The Options window will open. There, you can customize audio and video recording settings.
In this window, you can fine-tune the following audio recording options:
-
Volume normalization
-
Noise removal
Volume normalization while recording
Sometime volume levels in a recording vary. For example, the narrator’s voice may get louder and quieter throughout the recording. Volume level can be adjusted with normalization. By default, the option is disabled. To normalize sound volume in future recordings, click the Normalize clip volume while recording checkbox. If the volume level in your recordings usually seems fine, you can leave the option disabled.
Noise removal while recording
By default, automatic noise removal is off. If you don’t need to remove noise from your audio recordings or plan to configure noise removal manually for each recording, leave the option disabled.
If you want to remove noise automatically while recording, click the Automatic noise removal checkbox.
You can fine-tune several parameters of noise removal. To do this, click Customize.
The Noise reduction settings window will open:
You can sel ect from three noise removal presets: High, Medium, and Low. Also, you can apply custom settings and save them as your own preset. There are three settings to configure:
- Sensitivity
- Frequency smoothing
- Noise reduction
Click OK to save the settings. Now, they will be applied automatically to all audio recordings in your iSpring courses.
Note: iSpring selects the noise sample automatically, and you don’t have to choose it manually.
How to apply noise reduction settings to an existing audio recording
If your course already contains audio narration, you can manually set up noise removal for each audio recording.
To do this, click Manage Narration on the iSpring Suite ribbon in PowerPoint.
Select the audio track you need to remove noise fr om:
Click Edit Clip on the toolbar.
In the open window, click the arrow near the Remove Noise button on the toolbox. In the drop-down menu, sel ect Noise Reduction Settings.
The Noise Reduction Settings window will open:
Fine-tune the settings as you need and click OK.
To evaluate the quality of the recording after noise removal, click Play at the bottom of the Audio Editor window. Listen to the recording.
If the result doesn’t work for you, you can undo the settings. To do this, click Undo on the toolbar.
Customize the noise reduction settings once again. When you are fine with the result, click Save and Close on the toolbar to return to the course.
Please note that you can remove noise fr om a recording only once.
