Ambience sound effects

A low, even rush with nothing happening in it, the layer almost every interior scene needs first. It fills the silence a cut leaves behind without ever asking to be noticed.

Hundreds of voices at once with no word coming through. It is the fastest way to put people into a shot that has none in it, and it works behind dialogue because nothing in it competes for words.

A steady motor drone with a fine flutter riding on it. Reach for it when a space needs to feel serviced and occupied rather than abandoned, and cut it dead for the opposite effect.

Thousands of small splashes averaging into one even wash. Water carries a lot of high frequency, so this layer brightens a scene that has gone dull without anything else changing.

A high, dry chirr from thousands of small insects rubbing at once. It reads as warmth and stillness at the same time, which is why it does so much work under a scene with no dialogue.

Sparse dry creaks with long silences between them. A layer made of gaps rather than texture, useful when stillness itself is the point and a continuous bed would fill it in.
