impress greatly; "The speaker wowed the audience"
Wow is a relatively slow variation in the frequency of reproduced sound caused by slow speed variations in records, tape recorders, etc. Pitch fluctuations of one or two per second are classified as wow, while faster variations are called flutter. In spec sheets wow is usually rated, along with flutter, as a percentage where the percentage is the percent of pitch deviation produced by these two phenomenon in the machine. In practice we have found wow and flutter specs to be more of a ballpark or relative measure. Machines can behave very differently depending upon the type of tape used or even environmental factors which can affect tape consistency. This is especially true with cassette type tapes where the tape shell's interaction with the tape is a huge variable. Wow and flutter are almost never an issue in digital recorders because tape speed has no direct bearing on the pitch of the audio playback or recording.
A crisp, engaging story or pitch that frames the selling proposition as, at least in part, and entertainment experience: the sheer delight a prospect feels on imagining a VW Beetle parked in her driveway. The unexpected pleasure of design, the anticipated compliments of friends and passers-by: it all adds up to, "Wow!" XYZ
Fluctuation in pitch as a result of mechanical recording or reproducing equipment.
The speed variation of a mechanical playback device such as an LP record player or analog tape recorder. Short-term speed variations are sometimes called flutter. Digital recording and playback devices do not produce wow, because their outputs are controlled (and slightly delayed) by an internal clock mechanism. Wow created by warped LP records is called warp wow.
Small variations in the playback speed of a tape, CD, record or other audio/video device resulting in pitch wobbling or variation.
A low pitch audio artifact caused by speed fluctuation in the playback device. See " Flutter."
Wow is a relatively slow form of flutter (pitch variation) which can affect both gramophone records and tape recorders. In the latter, the collective expression "wow and flutter" is commonly used.
