## Node Properties

### Filename

Parameter ID: `GV_SOUND_FILENAME`

Sound files loaded into Cinema 4D via the **Attribute Manager** must have a format that Cinema can read (see [Sound Formats](https://help.maxon.net/c4d/en-us/Content/html/6201.html.md)). The file is opened by clicking on the button next to the file name field.

### Probe

Parameter ID: `GV_SOUND_PROBE` · Range: [0..1024]

In the **Attribute Manager**, you will also find a setting called Probe. This defines how many samples will be used to calculate the amplitude — the greater the number of samples in this calculation, the more damped the sound will become. In other words, the sound gets quieter as you increase the Probe value.
