2.1 Setup and device configuration
This chapter explains how Windows, Soundpad and voice applications must be configured, in order for Soundpad to work correctly.
By default Soundpad gets installed on the default recording device and it also configures all of its requirements automatically. But if Soundpad isn't working on your computer, then this chapter may help you to figure out the reason.
1. Right click the audio symbol in your system tray and then select Recording devices.
2. This window pops up.
It shows your recording devices and marks the default one with a green check icon.
This is the device control panel in Soundpad. You can access it by going to File ▷ Preferences and switching to the Devices tab.
The default recording device is marked with a green check icon, just like in Windows.
Soundpad is only activated for devices, whose Use-Checkbox is checked.
Furthermore, the checkbox Disable Windows Audio DRM Validation must be checked, too.
If everything is okay, the status will be a green Good, otherwise it is red and will show you further information about the reason.
In your voice application you need to select the same recording device, which you configured Soundpad for.
2.2 Audio configurationThere is a total of three volumes, which must be distinguished when using Soundpad.
- Soundpad speaker output volume:
You can adjust it with the volume slider in the main window.
- Soundpad microphone output volume:
It's the volume, at which others will hear your sounds.
You can adjust this volume in the audio control panel at File ▷ Preferences ▷ Audio ▷ Volume normalization. It is recommended, that you measure the volume of your voice with the integrated test and that you use dynamic volume adjustment. This will ensure, that your sounds are played as loud as your voice, no matter how loud or quiet the sound's original volume is.
Details are explained in the Audio preferences of Soundpad when you click the question marks therein.
- System wide microphone recording level:
It is the volume, that you can configure in this panel in Windows' audio preferences.Changing the microphone volume level or muting it does not affect Soundpad.
It means, that even if your microphone is muted and you play a sound with Soundpad, others will hear that sound.
Soundpad's algorithm is based on the EBU 128 recommendation, which is also used by European television and radio stations.
When used on a complete file, then the result is exact. But the analysis of a whole file can take some time. Therefore, when used with the option dynamic volume adjustment, then the first 6 seconds of a sound file are analyzed on playback to estimate the intial adjustment factor. This takes only a few milliseconds. The analysis continues while the file is being played back and the initial estimation becomes more and more precise and as such the volume adjustment improves.
This works independently of channels, meaning that a stereo file with a quiet left channel and a loud right channel will get normalized, so that both channels have the same volume.
You can enable this option at File ▷ Preferences ▷ Audio ▷ Block voice.
This option blocks everything your microphone records while you play a sound on the microphone and allows you to transmit your sounds in best quality without disturbing microphone noise.
Voice activation sound
You can enable this option at File ▷ Preferences ▷ Audio ▷ Play voice activation sound.
It can be of help if you're using voice activation instead of push-to-talk in your
Sometimes sounds may start off a little too quietly, so that the voice activation threshold is met too late and the beginning of the sound is not transmitted to your interlocuters.
This option plays another very short, but properly loud sound before playing the actual sound and triggers the voice activation beforehand. You can also exchange the provided sound with one of your own sounds.
The sound is not affected by the volume normalization and is played in its original volume.
