FreQuency is a music video game developed by Harmonix and published by SCEI. It was released in November 2001. A sequel, titled Amplitude was released in 2003.

Gameplay

In the game, a player portrays a virtual avatar called a "FreQ" (pronounced "freak"), and travels down an octagonal tunnel, with each wall containing a musical track. These tracks contain sequences of notes. As the player hits buttons corresponding to the note placement on the track, the "sonic energy" from within is released and the music plays. If the player plays two measures of the track without any errors, the track is "captured" and the music plays automatically until the next pre-determined section of the song.

Some tracks are bonus tracks and only open up when all notes are played, allowing the user to pick up "freestyle" points. Powerups are available which allow the immediate capturing of the track or the doubling of points. If a player continually misses notes, their energy meter reduces until the game is over.

High scores are achieved in the game by quickly moving from track to track, as they are completed, which increases a point multiplier. Tracks with more notes are worth more points, so choosing those over simple tracks is advantageous as well.

The game features 8 different 'arenas' that the player could attempt the song in. These arenas, as well as the tracks and notes, take on the appearance of Tron-style graphics, including limited video screens that would show the player's FreQ if the player was doing well, or static if the player was about to run out of power. Depending on the arena chosen, the track would curve and loop around indefinitely until the end of the song. One arena is noted for being a completely straight track, thus working well as a practice arena for some of the more difficult songs.

FreQuency allowed players to create remixes of any of the songs in the game. While the player was limited to the instruments and structure of the song, the remix could include different melodies or beat lines, change in tempo, and modulation of the sound of an instrument. Remixes could then be saved and played as normal songs, though no high score records are kept for these.

FreQuency was one of the first games to be supported by the PS2 Network Adapter, allowing for up to four players to play against each other as well as to trade their remixes. Multiplayer mode has all players attempting to complete the song on the same track, allowing for players to fight for as yet uncompleted tracks to get the highest score. New powerups only available in multiplayer mode are able to disrupt the performance of another player. However, Sony has shut down the matchmaking server for online play and has made no provisions for third-party replacements.^[1]

Songs

Some of the songs are actually "in-house" productions by Kasson Crooker, who served as a musical director for the game and is also a member of the band Freezepop. Some of his aliases include: DJ HMX (HMX standing for Harmonix, the game's developer), Symbion Project, and Komputer Kontroller.

Here is a list of artists who perform in the game, with corresponding song title, in the order they are encountered:

† - denotes an original track created specifically for FreQuency

1. Dub Pistols - "Official Chemical"
2. Lo Fidelity Allstars - "Lo Fi's In Ibiza"
3. Fear Factory - "FreQuency"
4. Paul Oakenfold - "See It"?
5. Ethan Eves - "Selecta"?

Stage 3

1. Powerman 5000 - "Danger is Go!"
2. Orbital - "Funny Break (One Is Enough) - Weekend Raver's Mix"
3. DJ Q-bert - "Cosmic Assassins"?

4. Komputer Kontroller - "Control Your Body"
5. Symbion Project - "FreQout"?
6. Surgecore - "Luge Crash"?
7. Robotkid vs - "End Of Your World"?

It should be noted that while a song called "Cosmic Assassins" is featured on DJ Q-Bert's album Wave Twisters, it is not the same as the one featured in the game.

In some versions, there is one extra song on first stage, called "Reeload - Why": [1]

Trivia

• The title of the game comes from Frequency modulation or "FM", commonly used for radio broadcasting. The game's sequel, Amplitude, is named for Amplitude modulation ("AM").
• The Crystal Method, BT, Akrobatik, Chris Child (of Surgecore), Melissa Kaplan, Freezepop, DJ HMX, Symbion Project and Komputer Kontroller would all be featured in the game's sequel, Amplitude.
• FreQuency was the first of many video games to feature music from the band Freezepop. Most of these games were developed by Harmonix including FreQuency's sequel, Amplitude, Karaoke Revolution and Guitar Hero & Guitar Hero II.

Frequency is the measurement of the number of occurrences of a repeated event per unit of time. It is also defined as the rate of change of phase of a sinusoidal waveform.

Measurement

To calculate the frequency of the event, the number of occurrences of the event within a fixed time interval are counted, and then divided by the length of the time interval.

To calculate the frequency of an event in experimental work however (for example, calculating the frequency of an oscillating pendulum) it is crucial that the time taken for a fixed number of occurrences is recorded, rather than the number of occurrences within a fixed time. This is because your random error is significantly increased performing the experiment the other way around. It [the frequency] is still calculated by dividing the number of occurrences by the time interval, however, the number of occurrences is fixed, not the time interval.

In SI units, the result is measured in hertz (Hz), named after the German physicist Heinrich Hertz. 1 Hz means that an event repeats once per second, 2 Hz is twice per second, and so on. This unit was originally called a cycle per second (cps), which is still sometimes used. Other units that are used to measure frequency include revolutions per minute (rpm). Heart rate and musical tempo are measured in beats per minute (BPM). Often, angular frequency is used instead of frequency, measured in radians per second (rad/s).

An alternative method to calculate frequency is to measure the time between two consecutive occurrences of the event (the period) and then compute the frequency f as the reciprocal of this time:

where

T= time or period is the period.

A more accurate measurement takes many cycles into account and averages the period between each.

Frequency of waves

Frequency has an inverse relationship to the concept of wavelength. The frequency f is equal to the speed v of the wave divided by the wavelength λ (lambda) of the wave:

In the special case of electromagnetic waves moving through a vacuum, then v = c, where c is the speed of light in a vacuum, and this expression becomes:

When waves travel from one medium to another, their frequency remains exactly the same — only their wavelength and speed change.

Apart from being modified by the Doppler effect or any other nonlinear process, frequency is an invariant quantity in the universe. That is, it cannot be changed by any linearly physical process unlike velocity of propagation or wavelength.

Examples

• The frequency of the standard pitch A above middle C is usually defined as 440 Hz, that is, 440 cycles per second (Listen (helpinfo)) and known as concert pitch, to which an orchestra tunes.
• A baby can hear tones with oscillations up to approximately 20,000 Hz, but these frequencies become more difficult to hear as people age.
• In Europe, the frequency of the alternating current in mains is 50 Hz (close to the tone G), however, in North America, the frequency of the alternating current is 60 Hz (close to the tone B flat — that is, a minor third above the European frequency). The frequency of the 'hum' in an audio recording can show where the recording was made — in Europe, or in America.
