While wow is perceived clearly as pitch variation, flutter can alter the sound of the music differently, making it sound ‘cracked’ or ‘ugly’. A recorded 1 kHz tone with a small amount of flutter (around 0.1%) can sound fine in a ‘dead’ listening room, but in a reverberant room constant fluctuations will often be clearly heard.
The changes in frequency are caused by irregular tape motion during recording or playback. For example, a change in the angular velocity of the capstan, or dragging of the tape within a reel or audio cassette shell. The terms "wow and flutter" are often referred to together, flutter being a higher-rate version of wow.
Wow and flutter are a change in frequency of an analog device and are the result of mechanical imperfections. Wow is a form of flutter that occurs at a slower rate. Wow and flutter are most noticeable on signals which contain pure tones. For LP records, the quality of the turntable will have a large effect on the level of wow and flutter.
Presentation time stamps (PTS) are embedded in MPEG transport streams to precisely signal when each audio and video segment is to be presented and avoid AV-sync errors. . However, these timestamps are often added after the video undergoes frame synchronization, format conversion and preprocessing, and thus the lip sync errors created by these operations will not be corrected by the addition ...
Audio players, on the other hand, specialize in digital audio. For example, AIMP exclusively plays audio formats. MediaMonkey can play both audio and video formats, but many of its features including media library, lyric discovery, music visualization, online radio, audiobook indexing, and tag editing are geared toward consumption of audio ...

Flutter-tonguing is a wind instrument tonguing technique in which performers flutter their tongue to make a characteristic "FrrrrrFrrrrr" sound. The effect varies according to the instrument and at what volume it is played, ranging from cooing sounds on a recorder to an effect similar to the growls used by jazz musicians.
