    en.wikipedia.org/wiki/Audio-to-video_synchronization

    If the sound source is 340 meters from the microphone, then the sound arrives approximately 1 second later than the light. The AV-sync delay increases with distance. During mixing of video clips normally either the audio or video needs to be delayed so they are synchronized. The AV-sync delay is static but can vary with the individual clip.

  3. Dissimilation - Wikipedia

    According to John Ohala, listeners are confused by sounds with long-distance acoustic effects. In the case of English /r/, rhoticization spreads across much of the word: in rapid speech, many of the vowels may sound as if they had an r. It may be difficult to tell whether a word has one source of rhoticity or two. When there are two, a listener ...

    Some audio conversion functions can be performed by software or by specialized hardware. For example, an audio transcoder converts from one compressed audio format to another (e.g., MP3 to AAC) by means of two audio codecs: One for decoding (uncompressing) the source and one for encoding (compressing) the destination file or stream.

    The voiced alveolar approximant is a type of consonantal sound used in some spoken languages.The symbol in the International Phonetic Alphabet that represents the alveolar and postalveolar approximants is ɹ , a lowercase letter r rotated 180 degrees.
