Vinyl records are easily scratched and vinyl readily acquires a static charge, attracting dust that is difficult to remove completely. Dust and scratches cause audio clicks and pops and, in extreme cases, they can cause the needle (stylus) to skip over a series of grooves, or worse yet, cause the needle to skip backwards, creating an unintentional locked groove that repeats the same 1.8 ...

Typically these tasks can be performed in a manner that is non-linear. Audio editors may process the audio ...

The smallest signal without dithering is 1, so the number of different levels is one less, 2 16 − 1. So for a 16-bit digital system, the Dynamic Range is 20·log(2 16 − 1) ≈ 96 dB. Sample accuracy/synchronisation Not as much a specification as an ability.
Linear timecode waveform as displayed in Audacity with 80 bit data frame highlighted. The basic format is an 80-bit code that gives the time of day to the second, and the frame number within the second.
On playback, the louder section has little or no muting applied, so the tape hiss is also left alone at its natural volume. When the softer section plays, having been amplified during recording, the expander mutes it down its original level. This also mutes down the tape hiss. [9] This causes the volume of tape hiss to change during playback.
