# \&echocancellation

Sender-Side Option! ([`&push`](https://docs.vdo.ninja/advanced-settings/setup-parameters/push))

## Aliases

* `&aec`
* `&ec`

## Options

Example: `&echocancellation=1`

| Value | Description                               |
| ----- | ----------------------------------------- |
| `0`   | Turns OFF the automatic echo-cancellation |
| `1`   | Turns ON the automatic echo-cancellation  |

## Details

Automatic echo-cancellation is ON by default in VDO.Ninja.

You can turn off echo-cancellation by adding `&aec=0` to a source link (guest). If you are using [`&proaudio`](https://docs.vdo.ninja/advanced-settings/audio-parameters/and-proaudio), echo-cancellation gets turned off. You can enable it again with `&proaudio&aec=1`.

You can also switch it on or off via the audio settings. If you want the guests to be able to change the audio settings by themselves, use [`&mediasettings`](https://docs.vdo.ninja/advanced-settings/video-parameters/and-mediasettings) on the link of the guests, as per default only the director can change the audio settings of the guests.

May need to be disabled to use [`&proaudio`](https://docs.vdo.ninja/advanced-settings/audio-parameters/and-proaudio) on some older browsers.
