==== Freesound (<nowiki>https://freesound.org</nowiki>) is an audio OER repository. You can search for sounds in this repository. ====

You can use a search engine such as  [https://google.com Google search engine] or [https://duckduckgo.com/ DuckDuckGo] search engine, using a FOSS web browser such as [https://www.mozilla.org/ Mozilla Firefox]

# You can use a search engine such as Google search engine or DuckDuckGo search engine, using a FOSS web browser such as Mozilla Firefox.

This can be made easier by providing OER as a criteria in your search itself. In Google search you need to select Settings → Advanced Search. In Advanced Search, you can select Usage Rights as ‘free to use, share or modify, even commercially’ to get OER that you can re-use with or without modification.

When you visit the site or check a specific resource, you need to look for copyright information to ascertain that the audio resource is OER and you can re-use it. If the resource is not explicitly declared to be an OER (allowing you to re-use), you should not use it in creating your OER.

Audacity is very powerful audio editor, with many sophisticated features. For advanced features, refer to the [http://manual.audacityteam.org user manual] and [http://manual.audacityteam.org/man/tutorials.html tutorials] .

Just like you can cut (or copy) paste a selection of text in a text document, you can cut (copy) and paste a selection of audio in an audio file. You can use this function to remove any part of the audio clip you do not want. You can move a part of a clip from one place to another (for instance if you want to re-order responses in an interview). You can also delete a part of the clip also using the same functionality.
