A sound effect (or audio effect) is an artificially created or enhanced sound, or sound process used to emphasise artistic or other content of films and music or other media. Here we are thinking mainly of a sound recorded and presented to make a specific storytelling or creative point. Such effects are found on some few Focus tracks.
1. Elspeth of Nottingham. The sounds of birds and cows can be heard towards the end of the track and this is the first example of such a thing on a Focus recording.
2. Ship of memories. This track closes with wind and seagull sounds.
3. Red sky at night. This track begins and ends with the sound of a wind machine that appears to go on throughout the track.
4. Blizu Tébe. Seagulls are again heard both at the beginning and the end.
5. Flower shower. This strange track includes the sound of a bathroom shower.
6. Aya-yuppie-hippie-hee. At the beginning of this track van Leer blows a clay bird whistle.
7. Nature is our friend. The sound of ducks in the water and then various birds in a wood are heard throughout this track.
8. Let us wander. This track has a similar but different set of nature sounds near water and in woods.
