Audio: 500 Hz, 1 kHz, and 1.5 kHz tones (can be modulated quickly to produce different tones)

The last section consists of 2 kHz tone at -24dBFS on all six channels.

Used in television production and filmmaking post-production, a 2-pop is a 1 kHz tone that is one frame long and placed 2 seconds before the start of program.

The SPIFC transfer shows a 21 kHz tone which casts some doubt on the quality of the transfer.

Scrape flutter measurement requires special techniques, often using a 10 kHz tone.

The modulation is repeated alternating Morse-style dots and dashes of a 1.3 kHz tone at the rate of two per second ( - -).

It is sometimes played in sequence between a 100 Hz and 10 kHz tone to ensure an accurate response from the equipment at varying audio frequencies.

In this experiment, mice were reared either in normal environments or in the presence of 7 kHz tones during early postnatal days.

The Bistro transmitter, operating at 4.7 m (64 MHz), produced near 200 W and was frequency-modulated by a 1 kHz tone.

"Deliver Me" has a stray 14 kHz tone throughout.
